Setting Forbidden Registration Mode
Configuring a port in forbidden registration mode deregisters all GMRP multicasts and prevents any
further GMRP multicast registration on the port.
To configure GMRP forbidden registration on a port, perform this task in privileged mode:
This example shows how to configure forbidden registration on port 2/10 and verify the configuration:
Console> (enable) set gmrp registration forbidden 2/10
GMRP Registration is set forbidden on port 2/10.
Console> (enable) show gmrp configuration
Global GMRP Configuration:
GMRP Feature is currently enabled on this switch.
GMRP Timers (milliseconds):
Join = 200
Leave = 600
LeaveAll = 10000

Setting the GARP Timers
Note
The commands set gmrp timer and show gmrp timer are aliases for set garp timer and show garp
timer.
Note
Modifying the GARP timer values affects the behavior of all GARP applications running on the switch,
not just GMRP. (For example, GVRP uses the same timers.)
You can modify the default GARP timer values on the switch.
