ExtremeWare 7.5 Command Reference Guide
ESRP Commands
configure vlan esrp group add esrp-aware-ports
configure vlan <vlan name> esrp group <number> add esrp-aware-ports [all |
<portlist>]
Description
Enables 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 receive ESRP PDUs, whether or not
they are connected to switches running the same ESRP group. 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.
The ESRP group number must be the same as the ESRP-aware VLAN number.
If you specify the
all
or
portlist
options, the ports must be connected to switches running ESRP, and
the ports must connect to the ESRP master and slave switches.
When an ESRP-aware switch receives an ESRP PDU, the software will lookup the group to which the
PDU belongs and will forward the ESRP PDU to the group's portlist and the CPU.
Example
The following command configures ESRP-aware VLAN
purple
to receive ESRP PDUs on ports 1, 2, 3,
and 4:
configure vlan purple esrp group 1 add esrp-aware-ports 1-4
History
This command was first available in ExtremeWare 6.2.2b81.

vlan name
Specifies an ESRP-aware VLAN name.
number
Specifies the ESRP group to which this ESRP-aware VLAN belongs.
all
Specifies all of the ports to be configured.
portlist
Specifies one or more ports or slots and ports. On a modular switch, can be a
list of slots and ports. On a stand-alone switch, can be one or more port
numbers. May be in the form 1, 2, 3-5, 2:*, 2:5, 2:6-2:8.
