configure vlan esrp elrp-master-poll enable
ExtremeWare Software 7.3.0 Command Reference Guide 1089
configure vlan esrp elrp-master-poll enable
configure vlan <vlan name> esrp elrp-master-poll enable {interval
<seconds>}
Description
Enables the use of ELRP by ESRP in the master state, and configures how often the master checks for
loops in the network.
Syntax Description
Default
• Use of ELRP in the master state—disabled
• Interval—1 second
Usage Guidelines
Use this command to enable the use of ELRP by ESRP in the master state. When an ESRP-enabled
switch is in the master state, and you enable elrp-master-poll, the switch periodically sends ELRP PDUs
at the configured interval level. If a loop is detected in the network, the transmitted PDUs are received
by the switch. The ESRP master switch then transitions to the slave state to break the network loop.
Specify the
interval
parameter to configure how often successive ELRP PDUs are sent while in the
master state. If you do not specify an interval value, the default value is used.
Example
The following command enables the use of ELRP in the master state on the ESRP-enabled VLAN
elrp1
:
configure vlan elrp1 esrp elrp-master poll enable
The following command configures the ESRP master to check for loops in the network every 3 seconds:
configure vlan elrp1 esrp elrp-master-poll enable interval 3
