Configure vPC+ to Cisco UCS

In DC2, Configure vPC domain 20 between DC2-N5K-1 and DC2-N5K-2 Perform these tasks:

1.Make sure that N5K-1 is always the vPC primary switch. 2.Use port channel ID 200 for the vPC peer link.

3.Do not add any new Layer 3 interfaces. 4.Use switch ID value 70.

5.Use port channel ID 10 toward Fabric Interconnect A (FI-A) 6.Use port channel ID 20 toward Fabric Interconnect B (FI-B)

7. Port channels to Cisco UCS should be configured as IEEE 802.1Q trunk interfaces that allow only VLANs 30, 40, 70, and 71.
8. Make sure that port channels 10 and 20 come up without waiting for the standard forward-time delay.
9. In few months, our server team will connect a single-leg server on VLAN 300 that is connected to N5K-2. Make sure that the interface does not go down in a dual-active scenario.
10. Make sure the vPC peer devices are the primary devices on LACP and use

priority value 2500.

Configuring fabricpath switch id will flap vPCs. Continue (yes/no)? [no] yes
