]]> Comment on Cisco Virtual Switching Systems (VSS) by Scott Vieth http://shouldhavegonewithcisco.com/2009/03/09/cisco-virtual-switching-systems-vss/#comment-45498 Scott Vieth Wed, 22 Feb 2012 19:26:45 +0000 http://shouldhavegonewithcisco.com/2009/03/09/cisco-virtual-switching-systems-vss/#comment-45498 “If you choose to use the 16 port line cards for VSL links, there are some caveats. First, you have to be running the module in performance mode, meaning it now becomes an 8 port card (no over subscription of ports for VSL).”

1. If you change the entire WS-X6716-10GE to performance mode, it turns into a 4 port card:

no hw-module switch 1 slot 4 oversubscription

2. If you change just port group 4 [ports 13-16] to performance mode, it turns into a 13 port card:

no hw-module switch 1 slot 4 oversubscription port-group 4

3. If you change two port groups to performance mode, it turns into a 9 port card:

no hw-module switch 1 slot 4 oversubscription port-group 4
no hw-module switch 1 slot 4 oversubscription port-group 3

4. If you change three port groups to performance mode, it turns into a 5 port card

no hw-module switch 1 slot 4 oversubscription port-group 4
no hw-module switch 1 slot 4 oversubscription port-group 3
no hw-module switch 1 slot 4 oversubscription port-group 2

5. Changing all four of the port groups to performance mode one-at-a-time is the same as changing the whole card with one command (you end up with a four-port 10Gig card).

What about setting MED ? Router B advertises the default route with MED 50 and Router A sets MED 100. So the PE conneting Router D will prefer to send the traffic to Router B, right?

It turns out, a Giant is anything over the 1500 MTU so even if you increase the MTU on the interface config, that doesnt change the counter behavior. Nice post!
