per recommended guidelines to make vPC peer-switch operational.

Configuring a Hybrid vPC Peer Switch Topology
You can configure a hybrid vPC and non-vPC peer switch topology by using the spanning-tree
pseudo-information command to change the designated bridge ID so that it meets the STP VLAN-based
load-balancing criteria and then change the root bridge ID priority to a value that is better than the best bridge
priority. You then enable the peer switch. For more information, see the command reference for your device.
If you previously configured global spanning tree parameters and you subsequently configure spanning
Note
tree pseudo information parameters, be aware that the pseudo information parameters take precedence
over the global parameters.
Before You Begin
Ensure that you have enabled the vPC feature.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# spanning-tree pseudo-information
3. switch(config-pseudo)# vlan vlan-id designated priority priority
4. switch(config-pseudo)# vlan vlan-id root priority priority
5. switch(config-pseudo)# exit
6. switch(config)# vpc domain domain-id
7. switch(config-vpc-domain)# peer-switch
8. switch(config-vpc-domain)# exit
9. (Optional) switch(config)# show spanning-tree summary
10. (Optional) switch(config)# copy running-config startup-config
