Creating a vPC Peer Link
Command or Action
Step 4
switch# show vpc brief
Step 5
switch# copy running-config startup-config
This example shows how to configure a vPC peer link:
switch# configure terminal
switch(config)# interface port-channel 20
switch(config-if)# vpc peer-link
Checking the Configuration Compatibility
After you have configured the vPC peer link on both vPC peer switches, check that the configurations are
consistent on all vPC interfaces.
Beginning with Cisco NX-OS Release 5.0(2)N1(1), the The following QoS parameters support Type 2
Note
consistency checks:
• Network QoS—MTU and Pause
• Input Queuing —Bandwidth and Absolute Priority
• Output Queuing—Bandwidth and Absolute Priority
In the case of a Type 2 mismatch, the vPC is not suspended. Type 1 mismatches suspend the vPC.
Command or Action
switch# show vpc consistency-parameters {global
| interface port-channel channel-number}
This example shows how to check that the required configurations are compatible across all the vPC interfaces:
switch# show vpc consistency-parameters global
