User Guidelines
This command configures the DCPDP transmission and timeout values. If an
MLAG switch does not receive DCPDP messages from the peer for the
configured timeout value, it takes the decision to transition its role (if
required).
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-vpc 1)#peer detection interval 750 timeout 3000
peer-keepalive destination
Use the peer-keepalive destination command to enable the Dual Control
Plane Detection Protocol with the configured IP address of the peer MLAG,
the local source address and the peer timeout value. The UDP port on which
the MLAG switch listens to the Dual Control Plane Detection Protocol
messages is also configurable with this command.
Use the no form of the command to return the configuration to the default.
