configure esrp timer premaster

configure esrp esrpDomain timer premaster seconds

Description

Configures the ESRP pre-master timeout value.

Syntax Description

esrpDomain Specifies an ESRP domain name.
seconds Specifies the maximum length of time, in seconds, that the transitioning master This command is available on the ExtremeSwitching X440-G2, X450-G2, X460-G2, X465, X590, X620, X670-G2, X690, X695, X870, 5320, 5420, 5520 series switches. remains in the pre-master state. The range is 6 to 1024.

Default

The default timeout is 6 seconds (three 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 three 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} | {type [vpls-redundancy | standard]} } command.

Caution

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
