ESRP Commands
Switch Behavior . If a switch is master, it actively provides Layer 3 routing services to other VLANs,
and Layer 2 switching between all the ports of that VLAN. Additionally, the switch exchanges ESRP
packets with other switches that are in slave mode.
If a switch is in slave mode, it exchanges ESRP packets with other switches on that same VLAN. When
a switch is in slave mode, it does not perform Layer 3 routing or Layer 2 switching services for the
VLAN.
Updating the Election Algorithm . ESRP uses the default election policy for extended mode. If you
have an ESRP domain operating in standard mode, the domain ignores the sticky and weight
algorithms. To change the election algorithm, you must first disable the ESRP domain and then
configure the new election algorithm. If you attempt to change the election algorithm without disabling
the domain first, an error message appears.
To disable the ESRP domain, use the following command:
disable esrp {<esrpDomain>}
To modify the election algorithm, use the following command:
configure esrp <esrpDomain> election-policy [ports > track > priority | ports > track
> priority > mac | priority > mac | priority > ports > track > mac | priority > track
> ports > mac | sticky > ports > track > priority | sticky > ports > track > priority
> mac | sticky > ports > track > priority > mac > weight | sticky > priority > mac |
sticky > priority > ports > track > mac | sticky > priority > track > ports > mac |
sticky > track > ports > priority > | sticky > track > ports > priority > mac
Example
The following command configures the election algorithm to use tracking information as the first
criteria for determining the ESRP master switch for ESRP domain :
esrp1
configure esrp esrp1 election-policy track > ports > priority > mac
