c. Configure the keepalive source and destination IP address.
(QCT) #config
(QCT) (Config)#mlag peer-keepalive destination 192.168.0.1 source 192.168.0.2
d. Configure the DCPDP transmission interval and reception timeout values (optional).

The administrator must ensure that the port channel configurations on both devices are in sync before
enabling MLAG. After the MLAG interfaces are enabled, the MLAG interfaces are operationally shut down.
The MLAG component exchanges information regarding the port members that constitute the Port-channel
on each device. Once this information is populated on both devices, the MLAG interfaces are operationally
up and traffic forwarding on MLAG interfaces is allowed. Port-channels must be configured on both devices
as MLAG interfaces for the MLAG interface to be enabled. Also, the port-channel-number: MLAG-Id pair
must be the same on both the primary and secondary devices.
Member ports can be added or removed from the MLAG interface. If a port is added as a port member to a
MLAG interface, the Primary allows the port member if the maximum criteria is satisfied. When a port
