Default
The default hello timer is 2 seconds.
Usage Guidelines
The timer specifies the interval, in seconds, for exchanging keep-alive packets between the ESRP
switches for this ESRP domain. A lower value specifies a more frequent exchange of keep-alive
messages, resulting in the faster detection of a failover condition. The timer setting must be configured
identically for the ESRP domain across all participating switches. To see the hello settings, use the
command.
esrp {<name>}
The range is 1 to 255.
seconds
If your configuration contains more than 2,000 ESRP VLANs and 256,000 FDB entries, Extreme
Networks recommends a timer setting greater than 3 seconds.

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 we

configure esrp timer neighbor
Example
The following command configures the ESRP hello timer to 4 seconds for the ESRP domain esrp1:
configure esrp esrp1 timer hello 4
