configure esrp group

configure esrp esrpDomain group number

Description

Configures the group number to be used for the ESRP domain.

Syntax Description

esrpDomain Specifies an ESRP domain name.
group number Specifies the ESRP group number to which this ESRP domain should be added. The range is 0 through 31.

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 seven ESRP groups can be defined within the same networked broadcast domain. In addition, a maximum of seven distinct ESRP groups can be supported on a single ESRP switch. You can configure a maximum of 32 ESRP groups in a network.

The range for the group_number parameter is 0 through 31.

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 the same ESRP HA ports must be members of different ESRP groups.

You must first disable an ESRP domain before you modify an existing or add a new group number. If you try to modify the group number without disabling the ESRP domain, an error message similar to the following is displayed:

ERROR: can't change ESRP group for active domain "esrp1"!

To disable an ESRP domain, use the disable esrp {esrpDomain} command.

Example

The following command configures ESRP domain esrp1 to be a member of ESRP group 2:

configure esrp esrp-1 group 2
