Manually Configuring The System Priority - Cisco AP775A - Nexus Converged Network Switch 5010 Configuration Manual

Manually Configuring the System Priority

Step 4
Step 5
This example shows how to configure a vPC domain MAC address:
switch# configure terminal
switch(config)# vpc domain 5
switch(config-if)# system-mac 23fb.4ab5.4c4e
Manually Configuring the System Priority
When you create a vPC domain, the system automatically creates a vPC system priority. However, you can
also manually configure a system priority for the vPC domain.
Note We recommend that you manually configure the vPC system priority when you are running LACP to
ensure that the vPC peer switches are the primary switches on LACP. When you manually configure the
system priority, ensure that you configure the same priority value on both vPC peer switches. If these
values do not match, vPC will not come up.
Before You Begin
Ensure that you have enabled the vPC feature.
You must configure both switches on either side of the vPC peer link with the following procedure.
