Adding servers to VPC domain

CiscoBrownBelt

Level 6

So if I have 2x Nexus switches joined to a VPC domain 1 and connect a server to both of these switches, would I configured the ports on the switch for the servers to be in another port-channel and another VPC domain let's say vpc 2. These configs look correct:

 

conf t
int e1/1-2
channel-group 2 mode active
int port-channel 2
vpc domain 2

I assume you may have missed this in your post, but are the IPs of the VLAN2 interfaces different?

Believe you need to use the "peer-switch" command under the vPC domain config. The spanning tree priority for the VLANs in the vPC will need to be identical on both switches. However, its implementation depends on your environment:

Check page 57 of the attached link:

Sorry yes that was a typo.

 

Ok yes I added the "peer-switch".

So in a topology where 2x 95k Nexus will be Core, and 4x 93k Nexus will be access, is it best to join the 2x 9504 in a VPC domain let's say VPC domain 10, then 1st pair of 93k as VPC Domain11, next pair VPC domain 12.

Just do all SVI on the cores, only 1 SVI for manangement on Access switches, then configure trunks between access and core switches if you only have 1 uplink?
