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.

As of Cisco IOS Release 12.2(18)SXE, the Cisco 7600 SIP-200 has the following restrictions:

The Cisco 7600 SIP-200 is not supported with a Supervisor Engine 1, Supervisor Engine 1A, Supervisor Engine 2, or Supervisor Engine 720A.

A maximum number of 200 PVCs or SVCs using Link Fragmentation and Interleaving (LFI) is supported for all ATM SPAs (or other ATM modules) in a Catalyst 6500 Series switch.

AToM (ATMoMPLS, FRoMPLS, HDLCoMPLS, and PPPoMPLs) on a SPA requires a Cisco 7600 SIP-200, FlexWAN, Enhanced FlexWAN, or OSM PXF interface as the core-facing interface.

AToM (ATMoMPLS, FRoMPLS) on SIP-200 also are supported with a Cisco 7600 SIP-400 as the core-facing interface.

Cisco 7600 SIP-400 Restrictions

As of Cisco IOS Release 12.2(18)SXE, the Cisco 7600 SIP-400 has the following restrictions:

The Cisco 7600 SIP-400 is not supported with a Supervisor Engine 1, Supervisor Engine 1A, or Supervisor Engine 2. It is also not supported with a Supervisor Engine 720 PFC3A, or in PFC3A mode.

For more information about the requirements for Policy Feature Cards (PFCs) on the Catalyst 6500 Series switch, refer to the Release Notes for Cisco IOS Release 12.2(33)SXH and Later Releases at the following URL:
http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/release/notes/ol_14271.html#wp2561312

The Cisco 7600 SIP-400 is not supported with PFC-2 based systems.

A maximum number of 200 PVCs or SVCs using Link Fragmentation and Interleaving (LFI) is supported for all ATM SPAs (or other ATM modules) in a Catalyst 6500 Series switch.

For AToM in releases prior to Cisco IOS Release 12.2(33)SXH, the Cisco 7600 SIP-400 does not support the following features when it is located in the data path. This means you should not configure the following features if the SIP is facing the customer edge (CE) or the MPLS core:

HDLCoMPLS

PPPoMPLS

Virtual Private LAN Service (VPLS)

For AToM beginning in Cisco IOS Release 12.2(33)SXH, the Cisco 7600 SIP-400 supports the following features on CE-facing interfaces:

Virtual Private LAN Service (VPLS)

The Cisco 7600 SIP-400 supports EoMPLS with directly connected provider edge (PE) devices when the Cisco 7600 SIP-400 is on the MPLS core side of the network.

The Cisco 7600 SIP-400 does not support the ability to enable or disable tunneling of Layer 2 packets, such as for the VLAN Trunking Protocol (VTP), Cisco Discovery Protocol (CDP), and bridge protocol data unit (BPDU).

Displaying the SIP and SSC Hardware Type

To verify the SIP or SSC hardware type that is installed in your Catalyst 6500 Series switch, you can use the show module command. There are other commands on the Catalyst 6500 Series switch that also provide SIP hardware information, such as the show idprom command and show diagbus command.

Table 3-1 shows the hardware description that appears in the show module and show idprom command output for each type of SIP that is supported on the Catalyst 6500 Series switch.
