Supported SIP Features
The Cisco 7600 SIP-200, Cisco 7600 SIP-400, and Cisco 7600 SIP-600 are high-performance, feature-rich SPA interface processors that function as carrier cards for shared port adapters (SPAs) on the Catalyst 6500 Series switch. These SIPs are supported on the Cisco 7600 series router and Catalyst 6500 series switch, and are compatible with one or more platform-independent SPAs. For more information on SPA compatibility, see the "SIP, SSC, and SPA Compatibility" section on page 2-3.
The Catalyst 6500 series switch can provide edge aggregation services, and the SIPs provide a cost-effective solution for customers seeking moderate- to high-port density and line rate services:
•The Cisco 7600 SIP-200 provides WAN edge aggregation through lower-speed and low-density SPAs for network environments requiring regional office connectivity to headquarters, or collapsed LAN/WAN deployment.
•The Cisco 7600 SIP-400 provides higher-speed, high-density link aggregation for network environments requiring leased line and metro aggregation.
•The Cisco 7600 SIP-600 provides a high-speed interface for WANs and metro aggregation.
Note Support for the Cisco 7600 SIP-600 was removed in Cisco IOS Release 12.2(33)SXH and restored in Cisco IOS Release 12.2(33)SXI and later releases.
Note The Cisco 7600 SIP-600 should not be used in the same chassis with an IPsec VPN SPA.
