After you have configured the vPC peer link on both vPC peer switches, check that the configurations are consistent on all vPC interfaces.
Parameter |
Default Setting |
switch# show vpc consistency-parameters {global | interface port-channel channel-number} |
Displays the status of those parameters that must be consistent across all vPC interfaces. |
This example shows how to check that the required configurations are compatible across all the vPC interfaces:
switch# show vpc consistency-parameters global
Legend:
Type 1 : vPC will be suspended in case of mismatch
