Cisco 7600 ES20 Ethernet Line Card Restrictions

This section documents unsupported features and feature restrictions for the ES20 line card on the Cisco 7600 series router.

As of Cisco IOS Release 12.2(33)SRB, ES20 line card:

•Is not supported by the Supervisor Engine 32e.

•Is supported by the Supervisor Engine 720 PFC3B and Supervisor Engine 720 PFC3BXL.

•Is 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 Cisco 7600 series router, refer to the Release Notes for Cisco IOS Release 12.2SR for the Cisco 7600 Series Routers at http://www.cisco.com/en/US/docs/ios/12_2sr/release/notes/122SRrn.html

Switch Port Analyzer (SPAN) Restrictions

Follow these SPAN restrictions when you configure a ES20 line card on the Cisco 7600 series router:

•SPAN is not supported on EVC ports.

•Traffic is incorrectly relayed to a local SPAN port instead of the SPAN destination port when the following conditions occur:

•When the SPAN source and SPAN destination ports belong to ports [0-9] or both ports belong to ports [10-19]

•The SPAN source port has a QoS policy-map attached and SPAN traffic matches that policy-map except for class-default.

Using ports [0-9] as SPAN source and [10-19] as SPAN destination or vice versa to avoid the above mentioned limitations.

•You cannot use Gi|Te x/0/1 as a SPAN source port when the diagnostic test TestMacNotification is enabled.

For information the diagnostic tests, refer to Cisco 7600 Series Cisco IOS Software Configuration Guide, 12.2SX - Online Diagnostic Tests at:

http://www.cisco.com/en/US/docs/routers/7600/ios/12.2SR/configuration/guide/diagtest.html

Displaying the Cisco 7600 Series Ethernet Services 20G Line Card Type

To verify the ES20 line card hardware type that is installed in your Cisco 7600 series router, you can use the show module command. There are other commands on the Cisco 7600 series router that also provide ES20 line card hardware information, such as the show idprom command and show diagbus command. For a summary of some other ES20 line card commands, see Chapter "Command Summary for the Cisco 7600 Series Ethernet Services 20G Line Card."

The following example shows output from the show module command on the Cisco 7600 series router with an ES20 line card installed in slot 2:
