ESRP Commands
clear esrp sticky
clear esrp <esrpDomain> sticky
Description
Clears the stickiness in the ESRP domain and forces the election of the ESRP master switch.
Syntax Description
Default
N/A.
Usage Guidelines
Use the
clear esrp sticky
command to force the election of the ESRP master switch. Before using
this command, schedule a downtime for your network.
For example, without stickiness configured, if an event causes the ESRP master to failover to the
backup, the previous backup becomes the new master. If another event causes the new master to return
to backup, you have experienced two network interruptions. To prevent this, use the
configure esrp
election-policy
and select stickiness as an election algorithm.
If you use sticky as an election metric, and an event causes the ESRP master to failover, ESRP assigns
the new master with the highest sticky election metric of 1. Therefore, regardless of changes to the
neighbor’s election algorithm, the new master retains its position. Sticky is set on the master switch
only.
ESRP re-election can occur if sticky is set on the master and a local event occurs. During this time, if the
current master has lower election parameters, the backup can become the new master.
If you use
clear esrp <esrpDomain> sticky
command, it only affects the current master and can
trigger ESRP re-election.
Example
The following command clears the stickiness on the ESRP domain esrp1 :
clear esrp esrp1 sticky
