Cisco Systems RJ-45-to-AUX Displaying the GMRP Configuration, Setting GMRP Timers, Displaying GMRP Timers

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

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
Timer Timer Value (milliseconds)
