White Paper

In a Cisco Virtual Switching System environment, the system PFC mode is negotiated between the supervisor

engines much earlier in the system initiation process. Additionally, there may also be a discrepancy between PFCs

used on the supervisor engines and those used on the DFCs for other VSL modules. As a result, you may encounter

instances where a module configured to support VSL member links may not be brought up because of a PFC or DFC

mismatch.

To remedy this situation, a new command allows you to manually specify the system-wide PFC mode to PFC3C

(from PFC3CXL). This configuration follows:

vss#conf t

Enter configuration commands, one per line. End with CNTL/Z.

vss(config)#platform hardware vsl pfc mode pfc3c

vss(config)#^Z

You must restart the system to activate this command. When the system is reloaded, you can verify the operational

mode of the system by issuing the following command:

vss#sh platform hardware pfc mode

PFC operating mode : PFC3C

Configured PFC operating mode : PFC3C

Using the Cisco Network Analysis Module in a Cisco Virtual Switching System Environment

The Cisco Network Analysis Modules (WS-SVC-NAM-1 and WS-SVC-NAM-2) are integrated and powerful traffic-

monitoring solutions for the Cisco Catalyst 6500 (Figure 15). Cisco NAMs combine a rich set of embedded data

collection and analysis capabilities with a remotely accessible, Web-based management console, all of which reside

on a single blade. The embedded Web-based Cisco Traffic Analyzer console offers quick access to configuration

menus and presents easy-to-read performance reports on data, voice, and video traffic. The Cisco NAM provides

both the ability to analyze packets and the ability to analyze them from within the switch or router itself, givin g greater

insight into how the network is being used and how users experience the services on the network.

In order to use the network analysis module in a Cisco Virtual Switching System environment, the minimum version

must be Cisco Network Analysis Module Software 3.6(1a).

Administration of the Cisco NAM

The most direct change with Cisco NAM in a Cisco Virtual Switching System environment relates to the way you can

access or manage it. In a Cisco Virtual Switching System environment, a switch ID is required for many of the

commands used to administer the NAM. In the following example, the NAM is installed in switch 1, slot 3:

vss#sh module switch 1 slot 3

Switch Number: 1 Role: Virtual Switch Active
