Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Revenue Recognition The Company's revenue is primarily derived from the sale of networking products, which are tangible products containing software and non-software components that function together to deliver the tangible product's essential functionality. In addition to tangible products, the Company's sales arrangements may include other deliverables such as standalone software licenses, or service offerings. For multiple deliverable arrangements, the Company recognizes revenue in accordance with the accounting standard for multiple deliverable revenue arrangements, which provides guidance on whether multiple deliverables exist, how deliverables in an arrangement should be separated, and how consideration should be allocated. Software revenue recognition guidance is applied to the sales of the Company's standalone software products, including software upgrades and software that is not essential to the functionality of the hardware with which it is sold. Pursuant to the guidance of the accounting standard for multiple deliverable revenue arrangements, when the Company's sales arrangements contain multiple elements, such as products, software licenses, maintenance agreements, or professional services, the Company determines the standalone selling price for each element based on a selling price hierarchy. The application of the multiple deliverable revenue accounting standard does not change the units of accounting for the Company's multiple element arrangements. Under the selling price hierarchy, the selling price for each deliverable is based on the Company's vendor-specific objective evidence (“VSOE”), which is determined by a substantial majority of the Company's historical standalone sales transactions for a product or service falling within a narrow range. If VSOE is not available due to a lack of standalone sales transactions or lack of pricing within a narrow range, then third party evidence (“TPE”), as determined by the standalone pricing of competitive vendor products in similar markets, is used, if available. TPE typically is difficult to establish due to the proprietary differences of competitive products and difficulty in obtaining reliable competitive standalone pricing information. When neither VSOE nor TPE is available, the Company determines its best estimate of standalone selling price (“ESP”) for a product or service and does so by considering several factors including, but not limited to, the 12-month historical median sales price, sales channel, geography, gross margin objective, competitive product pricing, and product life cycle. In consideration of all relevant pricing factors, the Company applies management judgment to determine the Company's best estimate of selling price through consultation with and formal approval by the Company's management for all products and services for which neither VSOE nor TPE is available. Generally, the standalone selling price of services is determined using VSOE and the standalone selling price of other deliverables is determined by using ESP. The Company regularly reviews VSOE, TPE and ESP for all of its products and services and maintains internal controls over the establishment and updates of these estimates. In accordance with the software revenue recognition accounting standard, the Company continues to recognize revenue for software using the residual method for its sale of standalone software products and other software that is not essential to the functionality of the hardware with which it is sold. After allocation of the relative selling price to each element of the arrangement, the Company recognizes revenue in accordance with the Company's policies for product, software, and service revenue recognition. Business Combinations The Company applies the acquisition method of accounting for business combinations, including its acquisition of Enterasys Networks, Inc. on October 31, 2013. Under this method of accounting, all assets acquired and liabilities assumed are recorded at their respective fair values at the date of the completion of the transaction. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, intangibles and other asset lives, among other items. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). Market participants are assumed to be buyers and sellers in the principal (most advantageous) market for the asset or liability. Additionally, fair value measurements for an asset assume the highest and best use of that asset by market participants. As a result, the Company may have been required to value the acquired assets at fair value measures that do not reflect its intended use of those assets. Use of different estimates and judgments could yield different results. Any excess of the purchase price over the fair value of the net assets acquired is recognized as goodwill. Although the Company believes the assumptions and estimates it has made are reasonable and appropriate, they are based in part on historical experience and information that may be obtained from the management of the acquired company and are inherently uncertain. Unanticipated events and circumstances may occur that may affect the accuracy or validity of such assumptions, estimates or actual results. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company's consolidated statements of operations. Goodwill Goodwill is assessed for impairment annually or more frequently when an event occurs or circumstances change between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying value. Goodwill is tested for impairment at the reporting unit level at the beginning of fourth quarter of the fiscal year and at least annually thereafter. To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, the Company will then perform the two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. Under the two-step goodwill impairment test, the Company would, in the first step, compare the estimated fair value of a reporting unit to its carrying value. If the fair value of the reporting unit exceeds the carrying value, no impairment loss would be recognized. However, if the carrying value of the reporting unit exceeds its fair value, the goodwill of the unit may be impaired. The amount, if any, of the impairment is then measured in the second step in which the Company determines the implied value of goodwill based on the allocation of the estimated fair value determined in the initial step to all assets and liabilities of the reporting unit. Long-Lived Assets Long-lived assets include property and equipment, and service inventory. Property and equipment assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets or asset groups. The Company reduces the carrying value of service inventory to net realizable value based on excess and obsolete inventories which are primarily determined by age of inventory and future demand forecasts. Intangible Assets Intangibles assets are reviewed for impairment annually or more frequently when an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value. License agreements are presented at cost, net of accumulated amortization and are amortized over their estimated useful life. The in-process research and development efforts are monitored regularly for completion and once they are completed, the Company will determine whether the asset will continue to be an indefinite-lived asset or it has become a finite lived asset and apply the appropriate accounting accordingly. The Company determines that its in-process research and development project is complete when all material research and development costs have been incurred and no significant risks remain. The Company reviews the carrying value of indefinite-lived intangible assets for impairment at least annually during the last quarter of the fiscal year, or more frequently if it believes indicators of impairment exist.

Goodwill

Goodwill is assessed for impairment annually or more frequently when an event occurs or circumstances change between annual tests that would more likely than not reduce the fair value of the reporting unit below its carrying value.

Long-Lived Assets

Long-lived assets include property and equipment, and service inventory. Property and equipment assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets or asset groups may not be recoverable. If such facts and circumstances exist, the Company assesses the recoverability of these assets by comparing the projected undiscounted net cash flows associated with the related asset or group of assets over their remaining lives against their respective carrying amounts. Impairments, if any, are based on the excess of the carrying amount over the fair value of those assets or asset groups. The Company reduces the carrying value of service inventory to net realizable value based on excess and obsolete inventories which are primarily determined by age of inventory and future demand forecasts.

Intangible Assets

Intangibles assets are reviewed for impairment annually or more frequently when an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value. License agreements are presented at cost, net of accumulated amortization and are amortized over their estimated useful life. The in-process research and development efforts are monitored regularly for completion and once they are completed, the Company will determine whether the asset will continue to be an indefinite-lived asset or it has become a finite lived asset and apply the appropriate accounting accordingly. The Company determines that its in-process research and development project is complete when all material research and development costs have been incurred and no significant risks remain. The Company reviews the carrying value of indefinite-lived intangible assets for impairment at least annually during the last quarter of the fiscal year, or more frequently if it believes indicators of impairment exist.
