ESRP Commands
configure vlan esrp group
configure vlan <vlan name> esrp group <group_number>
Description
Configures the group number to be used for the ESRP VLAN.
Syntax Description
Default
The default group number is 0.
Usage Guidelines
Each group runs an instance of ESRP within the same VLAN or broadcast domain. A maximum of four
ESRP groups can be defined within the same networked broadcast domain. In addition a maximum of
four distinct ESRP groups can be supported on a single ESRP switch.You can configure a maximum of
32 ESRP groups in a network.
The most typical application for multiple ESRP groups is when two or more sets of ESRP switches are
providing fast-failover protection within a common subnet for two or more groups of users. An
additional use for ESRP groups is ESRP Host Attach; ESRP VLANs that share ESRP HA ports must be
members of different ESRP groups.
Example
The following command configures VLAN esrp-1 to be a member of ESRP group 2:
configure vlan esrp-1 esrp group 2
