Cisco Router ModelsCisco 路由器型號

The Cisco router portfolio offers different hardware profiles depending on the use and specific architecture of the device. They range from equipment designed for small businesses to equipment suitable for complex environments where very high performance and reliability are required, such as in the service provider fields.

Cisco 路由器產品線依裝置的用途與特定架構提供不同的硬體規格,範圍從專為小型企業設計的設備,到適用於需要極高效能與可靠性的複雜環境(例如電信服務供應商領域)的設備。

These different types of routers do not all have the same operating system. IOS, IOS XE, and IOS XR are all possible examples but for Enterprise architecture, the commonly used operating system is IOS XE.

這些不同類型的路由器並非全部使用相同的作業系統。IOS、IOS XE 與 IOS XR 都是可能的範例,但在企業架構中,常用的作業系統是 IOS XE。

In general, routers belong to a series but within the series, different models can be found characterized by different hardware profiles.

一般而言,路由器屬於某個系列,但在同一系列中,可以找到具有不同硬體規格的各種型號。

For example, referring to the Cisco Catalyst 8300 Series for Enterprise Branch, some of the possible options are:

舉例來說,以企業分公司適用的 Cisco Catalyst 8300 系列來說,一些可能的選項如下:
