Layer 2 Switching Commands
582
peer detection enable
Use the peer detection enable command to enable the Dual Control Plane
Detection Protocol. This enables the detection of peer MLAG switches and
suppresses state transitions out of the secondary state in the presence of peer
link failures.
Use the
no form of the command to disable the dual control plane detection
protocol.
Syntax
peer detection enable
no peer detection enable
Default Configuration
Dual Control Plane Detection Protocol is disabled by default.
Command Modes
MLAG Domain Configuration mode
Usage Guidelines
Use of the Dual Control Plane Detection Protocol is optional. It provides a
second layer of redundancy beyond that provided by the peer link protocol.
System that operate without the DCPDP protocol enabled (and use static
LAGs) run the risk of a split brain scenario in the case of peer link failure.
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 detection interval
Use this command to configure the peer detection transmission interval and
the detection interval. Use the no form of the command to return the
transmission and detection intervals to the default.
