resolve a configuration with two primary devices by identifying the presence of another peer
and taking appropriate action.
and taking appropriate action.
You must configure the DCPDP on an IP interface that none of the MLAG interfaces share.
After you have enabled DCPDP, it sends a control plane detection message to the peer once
every second. The message is unidirectional and contains the senders MAC address. When
a switch receives a control plane detection message, it sets the peer is UP variable to TRUE
to indicate that a peer is detected.

The DCPDP configuration includes the following components:
•
Peer IP address. The IP address of the peer switch, which you must configure before
you enable DCPDP.
you enable DCPDP.
•
Source IP address. The IP address from which the DCPDP packets are sent. This
configuration is also mandatory. On the receiving side, DCPDP checks if the source IP
address of the packet matches the configured peer IP address. Packets with an IP
address that does not match the configured peer IP address are discarded.

CLI: Configure the DCPDP on the MLAG Interfaces
1.
Configure the destination and source IP addresses of the peer on switch P.
For this configuration, switch P has an IP address of 192.168.105.1 and switch S has an
IP address of 192.168.104.1. Both switches can reach each other on the network.
