Configuring GMRP on the Switch
Setting Fixed Registration
When you configure a switch port in fixed registration mode, all the multicast groups that are currently
registered on all ports are registered on the port, but the port ignores any subsequent registrations or
deregistrations on other ports. A switch port in fixed registration mode continues to register the multicast
groups that are specific to the port. You must return the port to normal registration mode to deregister
the multicast groups on the port.
To set the fixed registration on a switch port, perform this task in privileged mode:
Task
Step 1
Set the fixed registration on a switch port.
Step 2
Verify the configuration.
This example shows how to set the fixed registration on port 2/10 and verify the configuration:
Console> (enable) set gmrp registration fixed 2/10
GMRP Registration is set fixed 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 Forbidden Registration
Setting a switch port in forbidden registration mode deregisters all GMRP multicasts and prevents any
further GMRP multicast registration on the port.
To set the forbidden registration on a switch port, perform this task in privileged mode:
Task
Step 1 Set the forbidden registration on a switch port.
Step 2 Verify the configuration.
This example shows how to set the 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.
