ESRP Commands
configure vlan esrp group delete esrp-aware-ports
configure vlan <vlan name> esrp group <group_number> delete
esrp-aware-ports [all | <portlist>]
Description
Disables selective forwarding on an ESRP-aware VLAN.
Syntax Description
Default
Disabled.
Usage Guidelines
An ESRP-aware switch floods ESRP PDUs to all ports in an ESRP-aware VLAN and the CPU. This
flooding increases the amount of network traffic because all ports, regardless if they are connected to
switches running the same ESRP group or not, receive ESRP PDUs. To reduce the amount of traffic, you
can select the ports that receive ESRP PDUs by configuring selective forwarding on an ESRP-aware
VLAN. By configuring selective forwarding, you create a portlist for the ESRP groups associated with
an ESRP-aware VLAN, and that portlist is used for forwarding ESRP PDUs on the relevant ports only.
If all ports are removed from the esrp-aware-ports list, selective forwarding is disabled.
Example
The following command disables selective forwarding for ESRP-aware VLAN purple :
configure vlan purple esrp group 1 delete esrp-aware-ports 1-4
