Configures the group number to be used for the ESRP domain.
| 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. |
The default group number is 0.
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.
The following command configures ESRP domain esrp1 to be a member of ESRP group 2:
configure esrp esrp-1 group 2
This command was first available in ExtremeXOS 11.0.
This command is available on all Universal switches supported in this document.
