Using ELRP with ESRP
ExtremeWare XOS 11.3 Concepts Guide
477
To disable the use of ELRP by ESRP in the pre-master state, use the following command:
configure esrp <esrpDomain> elrp-premaster-poll disable
Configuring Master Polling
If you enable the use of ELRP by ESRP in the master state, ESRP requests that ELRP packets are
periodically sent to ensure that there is no loop in the network while ESRP is in the master state. By
default, the use of ELRP by ESRP in the master state is disabled.
To enable the use of ELRP by ESRP in the master state on a per-ESRP domain basis, and to configure
how often the master checks for loops in the network, use the following command:
configure esrp <esrpDomain> elrp-master-poll enable {interval <interval>}
Where the following is true:
●
esrpDomain
—Specifies an ESRP domain name.
●
interval
—Specifies how often, in seconds, successive ELRP packets are sent. The default is 1
second, and the range is 1 to 64 seconds.
To disable the use of ELRP by ESRP in the master state, use the following command:
configure esrp <esrpDomain> elrp-master-poll disable
Configuring Ports
You can configure one or more ports of an ESRP domain where ELRP packet transmission is requested
by ESRP. This allows the ports in your network that might experience loops, such as ports that connect
to the master, slave, or ESRP-aware switches, to receive ELRP packets. You do not need to send ELRP
packets to host ports.
By default, all ports of the ESRP domain have ELRP transmission enabled on the ports.
If you change your network configuration, and a port no longer connects to a master, slave, or ESRP-
aware switch, you can disable ELRP transmission on that port. To disable ELRP transmission, use the
following command:
configure esrp <esrpDomain> delete elrp-poll ports [<ports> | all]
To enable ELRP transmission on a port, use the following command:
configure esrp <esrpDomain> add elrp-poll ports [<ports> | all]
Displaying ELRP Information
To display summary ELRP information, use the following command:
show elrp
In addition to displaying the enabled/disabled state of ELRP, the command displays the total number
of:
●
Clients registered with ELRP.
●
ELRP packets transmitted.
