Cisco Systems RJ-45-to-AUX manual Displaying the Gmrp Configuration, Setting Gmrp Timers, 158

To configure Fixed mode, use the following command:

Coriolis> (enable) set gmrp registration fixed 2/1

GMRP Registration is set fixed on port 2/1.

To configure Forbidden mode, use the following command:

Coriolis> (enable) set gmrp registration forbidden 2/1

GMRP Registration is set forbidden on port 2/1.

Displaying the GMRP Configuration

To display the GMRP configuration setting on the switch, use the following command:

Coriolis> (enable) show gmrp configuration

Global GMRP	Configuration:
GMRP Feature is currently enabled on this switch.
GMRP Timers	(milliseconds):
Join = 200
Leave = 600
LeaveAll = 10000
GMRP−Status	Registration	ForwallAll Port(s)
———————————	————————————	—————————— ————————————————
Enabled	Normal	Disabled	1/1−12
			2/1−11,2/13−48
Enabled	Forbidden	Disabled	2/12

Setting GMRP Timers

If you have many multicast groups, you can change the GMRP timer value to improve performance. The leave timer value must be equal to or greater than three times the join timer value. The leaveall timer value must be greater than the leave timer value.

You must change the timer values in this order: leaveall timer value, leave timer value, and then join timer value. If you try to set the join timer value before you change the leave timer value, an error message will result.

Let’s look at the commands to change the timer values:

Coriolis> (enable) set gmrp timer leaveall 8000

GMRP/GARP leaveAll timer value is set to 8000 milliseconds.

Coriolis> (enable) set gmrp timer leave 900

GMRP/GARP leave timer value is set to 900 milliseconds.

Coriolis> (enable) set gmrp timer join 300

GMRP/GARP join timer value is set to 300 milliseconds.

Displaying GMRP Timers

To display the GMRP timers, use the following command:

Coriolis> (enable) show gmrp timer
