To ensure that all the configuration parameters are compatible, we recommend that you display the
configurations for each vPC peer switch once you configure the vPC.

vPC Peer Links

A vPC peer link is the link that is used to synchronize the states between the vPC peer devices.
You must configure the peer-keepalive link before you configure the vPC peer link or the peer link will

vPC Peer Link Overview

You can have only two switches as vPC peers; each switch can serve as a vPC peer to only one other vPC
peer. The vPC peer switches can also have non-vPC links to other switches.
To make a valid configuration, you configure an EtherChannel on each switch and then configure the vPC
domain. You assign the EtherChannel on each switch as a peer link. For redundancy, we recommend that you
should configure at least two dedicated ports into the EtherChannel; if one of the interfaces in the vPC peer
link fails, the switch automatically falls back to use another interface in the peer link.
We recommend that you configure the EtherChannels in trunk mode.
Note
Many operational parameters and configuration parameters must be the same in each switch connected by a
vPC peer link. Because each switch is completely independent on the management plane, you must ensure
that the switches are compatible on the critical parameters. vPC peer switches have separate control planes.
After configuring the vPC peer link, you should display the configuration on each vPC peer switch to ensure
that the configurations are compatible.
