MLAG
The Dual Control Plane Detection Protocol is a UDP-based protocol. The
administrator must configure this protocol on an IP interface with a VLAN
that is not shared with any of the MLAG interfaces. This can include the out-
of-band port. When enabled, the dual-control plane detection protocol sends
a control plane detection message to the peer once every second. The
message is unidirectional and contains the sender’s 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.
Example
console(config)#vpc domain 1
console(config-vpc 1)#peer-keepalive enable
console(config-vpc 1)#peer-keepalive destination 192.168.0.2 source
192.168.0.1
console(config-vpc 1)#peer detection enable
console(config-vpc 1)#exit
peer-keepalive enable
Use the peer-keepalive enable command to enable the peer keep-alive
protocol on the peer link. When enabled, if an MLAG switch does not receive
keepalive messages from the peer within the timeout value and DCPDP is
disabled, the switch begins the process of transitioning to the primary role (if
standby).
Use the
no form of the command to disable the peer keep-alive protocol.
Syntax
