WS-X6716-10G Performance Mode

Depending on what kind of traffic you plan to push onto a 6716 module, you might need to run one of the port groups in performance mode. You loose 3 out of the four ports in that port group when you do this but you gain a bigger buffer. This is great for bursty traffic like multicast or when you are spanning multiple ports into one.

Implementation:

6509E(config)#no hw-module slot 8 oversubscription port-group 3

Verification:

6509E#show hw-module slot 8 oversubscription

port-group      oversubscription-mode

1               enabled

2               enabled

3               disabled

4               enabled

 Verification:

6509E#show int te 8/10

TenGigabitEthernet8/10 is administratively down, line protocol is down (disabled for performance)

  Hardware is C6k 10000Mb 802.3, address is 001c.f9d7.e400 (bia 001c.f9d7.e400)
