Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Organization and Summary of Significant Accounting Policies Organization Arista Networks, Inc. (together with our subsidiaries, “we,” “our,” "Arista," "Company" or “us”) is a supplier of cloud networking solutions that use software innovations to address the needs of large-scale internet companies, cloud service providers and next-generation enterprises. Our cloud networking solutions consist of our Extensible Operating System ("EOS"), a set of network applications and our Gigabit Ethernet switching and routing platforms. We are incorporated in the state of Delaware. Our corporate headquarters are located in Santa Clara, California, and we have wholly-owned subsidiaries throughout the world, including North America, Europe, Asia and Australia. Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Arista Networks, Inc. and its wholly-owned subsidiaries and have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete financial statements. All significant inter-company accounts and transactions have been eliminated. Our condensed consolidated financial statements and related financial information in this Quarterly Report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and related footnotes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, filed with the SEC on February 15, 2022. Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Those estimates and assumptions include, but are not limited to, valuation of inventory and contract manufacturer/supplier liabilities, accounting for income taxes, including the recognition of deferred tax assets and liabilities, valuation allowance on deferred tax assets and reserves for uncertain tax positions, revenue recognition and deferred revenue, allowance for doubtful accounts, sales rebates and return reserves, valuation of goodwill and acquisition-related intangible assets, estimate of useful lives of long-lived assets including intangible assets, and the recognition and measurement of contingent liabilities. We evaluate our estimates and assumptions based on historical experience and other factors and adjust these estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates. Risks and Uncertainties Global economic and business activities continue to face widespread macroeconomic uncertainties, including supply chain and labor shortages, inflation and monetary policy shifts, recession risks, the ongoing global coronavirus ("COVID-19") pandemic and potential disruptions from the Russia-Ukraine conflict and the U.S. trade war with China. Our contract manufacturers and suppliers have experienced workforce disruptions, delays in component sourcing, production and export of their products and component shortages and increased component costs, which have disrupted our supply chain and have impacted and will likely continue to impact our ability to supply products to our customers on a timely basis. While overall demand remains strong across our customers base, we believe ongoing supply disruptions combined with other supply chain related constraints could impact our ability to fulfill this increased demand and as a result could negatively impact our business in future periods. In addition, inflation pressure in our supply chain and scarcity of some materials needed to build our products have increased our cost of revenue and have impacted, and may continue to negatively impact our gross margin. Our operating cash flows have also been and may continue to be negatively impacted by increased component inventories on hand or at our contract manufacturers, awaiting supply of a limited number of scarce components necessary to build and ship the completed product. The extent of the impact on our operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, and the impact of any initiatives and programs we may undertake to address financial and operational challenges, will depend on future developments, the impact to our customers, partners, employees, contract manufacturers and supply chain, all of which continue to evolve and are unpredictable. Management continues to actively monitor the impact of these macroeconomic factors on the Company's financial condition, liquidity, operations, suppliers, industry, and workforce. As of the date of issuance of these condensed consolidated financial statements, the extent to which these factors may materially impact the Company's financial condition, liquidity, or results of operations is uncertain. Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires companies to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination in accordance with ASC 606. Under previous GAAP, an acquirer generally recognized assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 results in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. The ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company adopted this ASU as of January 1, 2022 on a prospective basis and the adoption impact was immaterial to the condensed consolidated financial statements. The standard did not impact acquired contract assets or liabilities from business combinations occurring prior to the adoption date.

This amount includes $8.3 million that was reclassified from Investments on our condensed consolidated balance sheet following the commencement of public market trading of the issuer in January 2022. This publicly-traded equity investment generated an unrealized gain of $7.5 million for the nine months ended September 30, 2022, and an unrealized loss of $0.9 million for the three months ended September 30, 2022. The unrealized gains and losses are included in Other income (expense), net on the unaudited Condensed Consolidated Statements of Operations. Refer to Note 3. Financial Statements Details. During the three and nine months ended on September 30, 2022, the Company did not make any transfers between the levels of the fair value hierarchy. Marketable debt securities The following table summarizes the amortized cost, unrealized gains and losses, and fair value of our debt securities measured at fair value on a recurring basis (in thousands): September 30, 2022 December 31, 2021 Amortized Cost Unrealized Gains Unrealized Losses Fair Value Amortized Cost Unrealized Gains Unrealized Losses Fair Value Commercial paper $ 3,487 $ — $ — $ 3,487 $ 141,274 $ — $ — $ 141,274 U.S. government 1,187,901 — (18,002) 1,169,899 1,060,716 3 (2,909) 1,057,810 Corporate bonds 902,133 — (18,349) 883,784 1,255,149 105 (3,028) 1,252,226 Agency securities 182,771 — (3,298) 179,473 291,558 36 (333) 291,261 Total $ 2,276,292 $ — $ (39,649) $ 2,236,643 $ 2,748,697 $ 144 $ (6,270) $ 2,742,571 For debt securities in unrealized loss positions, it is not likely that we will be required to sell such securities before recovery of their amortized cost basis nor do we have the intent to sell such securities before maturity; we invest in debt securities that have maximum maturities of two years and are generally deemed to be low risk based on their credit ratings from the major rating agencies. The longer the duration of these marketable securities, the more susceptible they are to changes in market interest rates and bond yields. Given the short-term and conservative nature of our portfolio, the unrealized losses are not related to credit risk; therefore, we did not recognize any credit losses or non-credit-related impairments related to our available-for-sale marketable debt securities for the three and nine months ended September 30, 2022. All unrealized losses were recognized in other comprehensive income (loss). Realized losses were immaterial for the three and nine months ended September 30, 2022.

The fair values of marketable debt securities, by remaining contractual maturities, are as follows (in thousands): September 30, 2022 Fair Value Due in 1 year or less $ 1,773,158 Due in 1 to 2 years 463,485 Total debt securities $ 2,236,643 The weighted-average remaining duration of our marketable debt securities is approximately 0.6 years as of September 30, 2022. As we view these marketable debt securities as available to support current operations, we classify marketable debt securities with maturities beyond 12 months as current assets under the caption "Marketable securities" on the condensed consolidated balance sheets. Assets measured at fair value on a non-recurring basis Non-Marketable Equity Securities We have non-marketable equity securities in privately-held companies that do not have readily-determinable fair values. These equity securities are included in Investments on the condensed consolidated balance sheets. Their initial cost is adjusted to fair value on a non-recurring basis based on observable price changes from orderly transactions of identical or similar securities of the same issuer, or for impairment. These investments are classified within Level III of the fair value hierarchy as we estimate the value based on valuation methods using the observable transaction price at the transaction date and other significant unobservable inputs, such as volatility, rights, and obligations related to these securities. In addition, the valuation requires management judgment due to the absence of market price and lack of liquidity. We did not record any realized gains or losses for our non-marketable equity securities measured at fair value on a non-recurring basis during the three and nine months ended September 30, 2022 and September 30, 2021. We recorded unrealized gains of $1.7 million and $16.7 million on non-marketable equity securities based on observable price changes from orderly transactions of identical or similar securities in three and the nine months ended September 30, 2022. We recorded immaterial unrealized losses in the three and nine months ended September 30, 2022. We evaluate our non-marketable equity securities for impairment at each reporting period via a qualitative assessment with various potential impairment indicators, including, but not limited to, an assessment of a significant adverse change in the economic environment, significant adverse changes in the general market condition of the geographies and industries in which our investees operate, and other publicly-available information that affected the value of the its non-marketable equity securities. The following table summarizes the activity related to our non-marketable equity securities as of September 30, 2022 and December 31, 2021 (in thousands): September 30, 2022 December 31, 2021 Cost of investments (1) $ 23,625 $ 14,933 Cumulative impairment and downward adjustment (629) — Cumulative upward adjustment (1) 16,681 5,314 Carrying amount of investments $ 39,677 $ 20,247

In addition, as of September 30, 2022 the company had entered into $844.2 million of binding contractual agreements with certain customers that are primarily related to future product shipments. Revenue from Total Remaining Performance Obligations Revenue from total remaining performance obligations represents contract liabilities, deferred revenue and unbilled contract revenue that will be recognized in future periods. As of September 30, 2022, approximately $1,220.5 million of revenue is expected to be recognized from remaining performance obligations, of which approximately 82% is expected to be recognized over the next two years and approximately 18% is expected to be recognized during the third to the fifth year. These amounts do not include the $844.2 million of binding contractual agreements related primarily to future product shipments outlined above. As of September 30, 2022, it is expected that the majority of the amounts allocated to these specific performance obligations will be recognized as revenue upon product shipment over the next two years; however, given the current uncertain supply chain environment and industry wide supply constraints, we may experience manufacturing and shipment delays or cancellations related to these performance obligations, which could impact revenue recognition.

Business Combination and Asset Acquisition [Abstract]
Acquisition, Goodwill and Acquisition-Related Intangible Assets	Acquisition, Goodwill and Acquisition-Related Intangible Assets Acquisitions During the nine months ended September 30, 2022, we completed two acquisitions of private companies for total consideration of $158.9 million including $4.0 million in common stock and the remainder in cash. The purchase prices included $62.3 million of intangible assets, $82.6 million of goodwill and $14.0 million of net tangible assets acquired. We also incurred certain acquisition-related expenses of $4.7 million, which primarily consisted of retention bonuses to continuing employees as well as professional and consulting fees. The intangible assets are amortized on a straight-line basis over their estimated useful lives, as we believe this method most closely reflects the pattern in which the economic benefits of the assets will be consumed. The following table sets forth the components of identifiable intangible assets acquired and their estimated useful lives as of the date of acquisition (in thousands, except years): Acquisition Date Fair Value Weighted Average Estimated Useful Life (in years) Developed technology $ 30,200 5.7 Customer relationships 28,700 7.0 Trade name 3,400 3.0 Total intangible assets acquired $ 62,300 Goodwill The changes in the carrying values of goodwill for the three and nine months ended September 30, 2022 are as follows (in thousands): Amount Balance at December 31, 2021 $ 188,397 Additions related to the acquisition completed in January 2022 28,518 Balance at March 31, 2022 $ 216,915 Additions related to the acquisition completed in June 2022 56,530 Measurement-period adjustments 49 Balance at June 30, 2022 $ 273,494 Measurement-period adjustments (2,476) Balance at September 30, 2022 $ 271,018 Acquisition-Related Intangible Assets Acquisition-related intangible assets were as follows (in thousands, except years): Gross Carrying Amount Accumulated Amortization Net Carrying Amount Weighted Average Remaining Useful Life (in years) December 31, 2021 Additions September 30, 2022 December 31, 2021 Amortization September 30, 2022 December 31, 2021 September 30, 2022 Developed technology $ 124,730 $ 30,200 $ 154,930 $ (53,663) $ (18,553) $ (72,216) $ 71,067 $ 82,714 4.5 Customer relationships 25,920 28,700 54,620 (7,899) (4,272) (12,171) 18,021 42,449 5.9 Trade name 8,990 3,400 12,390 (4,693) (1,340) (6,033) 4,297 6,357 2.8 Others 5,720 — 5,720 (5,550) (170) (5,720) 170 — 0.0 Total $ 165,360 $ 62,300 $ 227,660 $ (71,805) $ (24,335) $ (96,140) $ 93,555 $ 131,520 4.9 Amortization expense related to acquisition-related intangible assets was $9.3 million, and $7.3 million for the three months ended September 30, 2022 and 2021, and $24.3 million and $22.1 million for the nine months ended September 30, 2022 and 2021, respectively.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Purchase Commitments We outsource most of our manufacturing and supply chain management operations to third-party contract manufacturers, who procure components and assemble products on our behalf. A significant portion of our purchase orders to our contract manufacturers for finished products consists of non-cancellable purchase commitments. In addition, we purchase strategic component inventory from certain suppliers under non-cancellable purchase commitments, including integrated circuits, which are consigned to our contract manufacturers. As of September 30, 2022, we had non-cancellable purchase commitments of $4.3 billion, of which $3.1 billion have confirmed receipt dates within 12 months, and $1.2 billion have confirmed receipt dates greater than 12 months. These open purchase orders are considered enforceable and legally binding, and while we may have some limited ability to reschedule, and adjust our requirements based on our business needs prior to the delivery of goods or performance of services, this can only occur with the agreement of the related supplier. We also had deposits to our contract manufacturers to secure our purchase commitments in the amount of $124.7 million and $49.1 million as of September 30, 2022 and December 31, 2021, respectively, which were recorded within prepaid expenses and other current assets, as well as other assets in the condensed consolidated balance sheets. Guarantees We have entered into agreements with some of our direct customers and channel partners that contain indemnification provisions relating to potential situations where claims could be alleged that our products infringe the intellectual property rights of a third party. We have, at our option and expense, the ability to repair any infringement, replace product with a non-infringing equivalent-in-function product or refund our customers all or a portion of the value of the product. Other guarantees or indemnification agreements include guarantees of product and service performance and standby letters of credit for leased facilities and corporate credit cards. We have not recorded a liability related to these indemnification and guarantee provisions and our guarantee and indemnification arrangements have not had a significant impact on our consolidated financial statements to date. Legal Proceedings WSOU Investments, LLC On November 25, 2020, WSOU Investments LLC ("WSOU") filed a lawsuit against us in the Western District of Texas asserting that certain of our products infringe three WSOU patents. WSOU's allegations are directed to certain features of our wireless and switching products. WSOU seeks remedies including monetary damages, attorney's fees and costs. On February 4, 2021, we filed an answer denying WSOU's allegations. On November 5, 2021, the case was transferred to the Northern District of California. On March 30, 2022, WSOU dismissed one of the patents with prejudice, removing Arista wireless products from those accused of infringement. On July 1, 2022, the court stayed the case pending the resolution of an inter partes review of one of the patents-in-suit. We intend to vigorously defend against the claims brought against us by WSOU; however, we cannot be certain that any of WSOU's claims will be resolved in our favor, regardless of the merits of those claims. Any adverse litigation ruling could result in a significant damages award against us and injunctive relief. With respect to the legal proceedings described above, it is our belief that while a loss is not probable, it may be reasonably possible. Further, at this stage in the litigation, any possible loss or range of loss cannot be estimated; however, the outcome of litigation is inherently uncertain. Therefore, if this legal matter were resolved against us in a reporting period for a material amount, our consolidated financial statements for that reporting period could be materially adversely affected. Other matters In the ordinary course of business, we are a party to other claims and legal proceedings including matters relating to commercial, employee relations, business practices and intellectual property. We record a provision for contingent losses when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. As of September 30, 2022, provisions recorded for contingent losses related to other claims and matters have not been significant. Based on currently-available information, management does not believe that any additional liabilities relating to other unresolved matters are probable or that the amount of any resulting loss is estimable, and believes these other matters are not likely, individually and in the aggregate, to have a material adverse effect on our financial position, results of operations or cash flows; however, litigation is subject to inherent uncertainties and our view of these matters may change in the future. Were an unfavorable outcome to occur, there exists the possibility of a material adverse impact on our financial position, results of operations or cash flows for the period in which the unfavorable outcome occurs, and potentially in future periods.

Stockholders_ Equity and Stock-

Share-Based Payment Arrangement [Abstract]
Stockholders’ Equity and Stock-Based Compensation	Stockholders’ Equity and Stock-Based Compensation Stock Repurchase Program In April 2019, our board of directors authorized a $1.0 billion stock repurchase program (the "Repurchase Program"). This authorization allowed us to repurchase shares of our common stock over three years, and we completed our repurchases under the Repurchase Program during the fourth quarter of 2021. In the fourth quarter of 2021, our board of directors authorized an additional $1.0 billion stock repurchase program (the “New Repurchase Program”), which allows us to repurchase shares of our common stock to be funded from working capital. Repurchases may be made at management’s discretion from time to time on the open market, through privately negotiated transactions, transactions structured through investment banking institutions, block purchases, trading plans under Rule 10b5-1 of the Exchange Act, or a combination of the foregoing. The New Repurchase Program commenced in November 2021 and expires on the three-year anniversary thereof. The New Repurchase Program does not obligate us to acquire any of our common stock, and may be suspended or discontinued by us at any time without prior notice. As of September 30, 2022, the remaining authorized amount for stock repurchases under this program was approximately $259.6 million. A summary of the stock repurchase activity under the New Repurchase Program for the nine months ended September 30, 2022 is as follows (in thousands, except per share amounts): Nine Months Ended September 30, 2022 Aggregate purchase price $ 667,470 Shares repurchased 6,433 Average price paid per share $ 103.75 The aggregate purchase price of repurchased shares of our common stock is recorded as a reduction to retained earnings in our unaudited condensed consolidated statements of stockholders' equity. All shares repurchased have been retired. Equity Award Plan Activities 2014 Equity Incentive Plan In April 2014, our board of directors and stockholders approved the 2014 Equity Incentive Plan (the “2014 Plan”), effective on the first day that our common stock was publicly traded, and simultaneously terminated the 2004 and 2011 equity plans as to future grants; however, these plans will continue to govern the terms and conditions of the outstanding options previously granted thereunder. Awards granted under the 2014 Plan could be in the form of Incentive Stock Options (“ISOs”), Nonstatutory Stock Options (“NSOs”), Restricted Stock Units (“RSUs”), Restricted Stock Awards (“RSAs”) or Stock Appreciation Rights (“SARs”). The number of shares available for grant and issuance under the 2014 Plan increases automatically on January 1 of each year commencing with 2016 by the number of shares equal to 3% of the outstanding shares of our common stock on the immediately preceding December 31, but not to exceed 50,000,000 shares (the “2014 Plan Evergreen Increase”), unless our board of directors, in its discretion, determines to make a smaller increase. Effective January 1, 2022, our board of directors authorized an increase of 9,230,434 shares to the shares available for issuance under the 2014 Plan. As of September 30, 2022, there remained approximately 93.4 million shares available for issuance under the 2014 Plan. 2014 Employee Stock Purchase Plan In April 2014, our board of directors and stockholders approved the 2014 Employee Stock Purchase Plan (the “ESPP”). The ESPP became effective on the first day that our common stock was publicly traded. The number of shares reserved for issuance under the ESPP increases automatically on January 1 of each year by the number of shares equal to 1% of our shares outstanding on the immediately preceding December 31, but not to exceed 10,000,000 shares, unless our board of directors, in its discretion, determines to make a smaller increase. Effective January 1, 2022, our board of directors authorized an increase of 3,076,811 shares to the shares available for issuance under the ESPP.

Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying unaudited condensed consolidated financial statements include the accounts of Arista Networks, Inc. and its wholly-owned subsidiaries and have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) and the requirements of the U.S. Securities and Exchange Commission (the “SEC”) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP can be condensed or omitted. In management’s opinion, the unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments, which include only normal recurring adjustments, necessary for the fair presentation of our financial information. The results for the three and nine months ended September 30, 2022, are not necessarily indicative of the results expected for the full fiscal year. The condensed consolidated balance sheet as of December 31, 2021 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete financial statements. All significant inter-company accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the amounts reported and disclosed in the consolidated financial statements and accompanying notes. Those estimates and assumptions include, but are not limited to, valuation of inventory and contract manufacturer/supplier liabilities, accounting for income taxes, including the recognition of deferred tax assets and liabilities, valuation allowance on deferred tax assets and reserves for uncertain tax positions, revenue recognition and deferred revenue, allowance for doubtful accounts, sales rebates and return reserves, valuation of goodwill and acquisition-related intangible assets, estimate of useful lives of long-lived assets including intangible assets, and the recognition and measurement of contingent liabilities. We evaluate our estimates and assumptions based on historical experience and other factors and adjust these estimates and assumptions when facts and circumstances dictate. Actual results could differ materially from these estimates.
Risks and Uncertainties	Risks and Uncertainties Global economic and business activities continue to face widespread macroeconomic uncertainties, including supply chain and labor shortages, inflation and monetary policy shifts, recession risks, the ongoing global coronavirus ("COVID-19") pandemic and potential disruptions from the Russia-Ukraine conflict and the U.S. trade war with China. Our contract manufacturers and suppliers have experienced workforce disruptions, delays in component sourcing, production and export of their products and component shortages and increased component costs, which have disrupted our supply chain and have impacted and will likely continue to impact our ability to supply products to our customers on a timely basis. While overall demand remains strong across our customers base, we believe ongoing supply disruptions combined with other supply chain related constraints could impact our ability to fulfill this increased demand and as a result could negatively impact our business in future periods. In addition, inflation pressure in our supply chain and scarcity of some materials needed to build our products have increased our cost of revenue and have impacted, and may continue to negatively impact our gross margin. Our operating cash flows have also been and may continue to be negatively impacted by increased component inventories on hand or at our contract manufacturers, awaiting supply of a limited number of scarce components necessary to build and ship the completed product. The extent of the impact on our operational and financial performance, including our ability to execute our business strategies and initiatives in the expected time frame, and the impact of any initiatives and programs we may undertake to address financial and operational challenges, will depend on future developments, the impact to
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. ASU 2021-08 requires companies to recognize and measure contract assets and contract liabilities relating to contracts with customers that are acquired in a business combination in accordance with ASC 606. Under previous GAAP, an acquirer generally recognized assets acquired and liabilities assumed in a business combination, including contract assets and contract liabilities arising from revenue contracts with customers, at fair value on the acquisition date. ASU No. 2021-08 results in the acquirer recording acquired contract assets and liabilities on the same basis that would have been recorded by the acquiree before the acquisition under ASC Topic 606. The ASU is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company adopted this ASU as of January 1, 2022 on a prospective basis and the adoption impact was immaterial to the condensed consolidated financial statements. The standard did not impact acquired contract assets or liabilities from business combinations occurring prior to the adoption date.
