ExtremeWare XOS 11.5 Command Reference Guide
1279
configure esrp timer neighbor
configure esrp <esrpDomain> timer neighbor <seconds>
Description
Configures the ESRP neighbor timeout value.
Syntax Description
Default
The default neighbor timeout is 8 seconds (four times the hello timer).
Usage Guidelines
The neighbor timeout specifies the amount of time that ESRP waits before considering the neighbor
down. The neighbor value must be at least 3 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 to 1024 seconds.
To view the neighbor timer settings, use the
show esrp {<name>}
command.
In a large ESRP configuration, the slave ESRP domain might inadvertently become the master ESRP
domain. This can occur when FDB entries are flushed during a master-slave transition. To avoid this
Extreme Networks recommends the general neighbor and hello timeout guidelines listed in
Table 25
.
Example
The following command configures the ESRP neighbor timeout to 14 seconds for the ESRP domain
esrp1
:
configure esrp esrp1 timer neighbor 14
esrpDomain
Specifies an ESRP domain name.
seconds
Specifies the number of seconds after which an ESRP neighbor times out. The
range is 6 to 1024 seconds.
