configure esrp aware add selective-forward-ports

configure esrp domain aware add selective-forward-ports port_list {group group number}

Description

Enables selective forwarding by creating an aware port list and adds additional ports to the list.

Syntax Description

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

Default

The group number defaults to '0'.

Usage Guidelines

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.

Example

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
