This example shows how to configure a pure vPC peer switch topology:
switch# configure terminal
Enter configuration commands, one per line.
switch(config)# vpc domain 5
switch(config-vpc-domain)# peer-switch

configuration is enabled. Please make sure to configure spanning tree "bridge" priority as
per recommended guidelines to make vPC peer-switch operational.
switch(config-vpc-domain)# exit
switch(config)# spanning-tree vlan 1 priority 8192

Purpose
Enters global configuration mode.
Enters the vPC domain number that you want to
configure. The system enters the vpc-domain
configuration mode.
Enables the vPC switch pair to appear as a single
STP root in the Layer 2 topology.
Use the no form of the command to disable the peer
switch vPC topology.
Configures the bridge priority of the VLAN. Valid
values are multiples of 4096. The default value is
32768.
Exits the vpc-domain configuration mode.
(Optional) Displays a summary of the spanning tree
port states including the vPC peer switch.
(Optional) Copies the running configuration to the
startup configuration.
End with CNTL/Z.
