Configures the ESRP (Extreme Standby Router Protocol) pre-master timeout value.
| esrpDomain | Specifies an ESRP domain name. |
| seconds | Specifies the maximum length of time, in seconds, that the transitioning master VLAN (Virtual LAN) remains in the pre-master state. The range is 6 to 1024. |
The default timeout is 6 seconds (three times the hello timer).
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
Configure the pre-master state timeout only with guidance from Extreme Networks personnel. Misconfiguration can severely degrade the performance of ESRP and your switch.
The following command configures the pre-master timeout to 10 seconds for the ESRP domain esrp1:
configure esrp esrp-1 timer premaster 10
This command was first available in ExtremeXOS 11.0.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X590, X620, X690, X870 series switches.
