ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
1261
configure esrp elrp-master-poll enable
configure esrp <esrpDomain> elrp-master-poll enable {interval <interval>}
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.
Extreme Networks recommends that you enable both premaster and master polling when using ELRP
with ESRP. To enable premaster polling, use the
configure esrp <esrpDomain> elrp-premaster-
poll enable {count <count> | interval <interval>}
.
If you attempt to configure master polling before premaster polling, the switch displays an error
message similar to the following:
ERROR: Premaster-poll should be enabled before enabling master-poll!
If this happens, first configure premaster polling followed by master polling (if required).
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 ESRP domain
elrp1
:
configure esrp elrp1 esrp elrp-master poll enable
The following command configures the ESRP master to check for loops in the network every 3 seconds:
configure esrp elrp1 esrp elrp-master-poll enable interval 3
esrpDomain
Specifies an ESRP domain name.
interval
Specifies how often, in seconds, successive ELRP packets are sent. The
default is 1 second. The range is 1 to 64 seconds.
