ExtremeWare XOS 11.5 Command Reference Guide
1282
configure esrp timer premaster
configure esrp <esrpDomain> timer premaster <seconds>
Description
Configures the ESRP pre-master timeout value.
Syntax Description
Default
The default timeout is 8 seconds (four times the hello timer).
Usage Guidelines
The premaster timer specifies how long the ESRP domain stays in the pre-master state. The pre-master
timer expires if the neighbor agrees to be the slave. The premaster value must be at least four times the
hello timer value. Entering a value outside of that range generates an error message similar to the
following:
operation Failed. Valid timer relationship "neighbor timeout >= 3*hello ; neutral
timeout >= 2*hello ; premaster timeout >= 3*hello"!
The
seconds
range is 3*hello-1024.
To view the pre-master timer settings, use the
show esrp {<name>}
command.
CAUTION
Configure the pre-master state timeout only with guidance from Extreme Networks personnel. Misconfiguration can
severely degrade the performance of ESRP and your switch.
Example
The following command configures the pre-master timeout to 10 seconds for the ESRP domain
esrp1
:
configure esrp esrp-1 timer premaster 10
