Release History
Note For release history information about the introduction
of SPA support on the SIPs, refer to the corresponding "Overview"
chapters in the SPA technology sections of this document. In
addition, features specific to certain SPA technologies are
documented in the corresponding SPA sections of this document.
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.
This section provides a list of some of the primary features supported by the SIP hardware and software. For feature compatibility information by SIP and SPA combination, and information about configuring these features, see Chapter 4, "Configuring the SIPs and SSC."

Cisco 7600 SIP-600 in both the downlink (facing UPE) and uplink
(MPLS core).
•Output policing is not supported.
•On any Cisco 7600 SIP-600 Ethernet port subinterface
using VLANs, a unique VLAN ID must be assigned. This VLAN ID cannot
be in use by any other interface on the Catalyst 6500 Series
switch.
Note The Cisco 7600 SIP-600 should not be used in the same
chassis with an IPsec VPN SPA.
