Enables selective forwarding by creating an aware port list and adds additional ports to the list.
| domain | Specifies an ESRP domain name. |
| port_list | Specifies the ports to be added to the aware port list. |
| group number | Specifies the ESRP group within the given domain name |
The group number defaults to '0'.
An ESRP-aware switch floods ESRP PDUs from all ports in an ESRP-aware VLAN. This flooding creates unnecessary network traffic because some ports forward ESRP PDUs to switches that are not running the same ESRP groups. You can select the ports that are appropriate for forwarding ESRP PDUs by configuring selective forwarding on an ESRP-aware VLAN and thus reduce this excess traffic. Configuring selective forwarding creates a port list of only those ports that forward to the ESRP groups that are associated with an ESRP-aware VLAN. This ESRP-aware port list is then used for forwarding ESRP PDUs.
Use this command to create or add to an existing port list for the ESRP groups associated with an ESRP-aware VLAN.
The following command configures esrp domain (d1) to forward ESRP PDUs on ports 5:1, 5:2, and 6:2.
configure esrp d1 aware add selective-forward-ports 5:1,5:2,6:2 group 0
This command was first available in Extreme XOS 12.0.
This command is available on all platforms.
