Enabling GMRP Forward-All Option

When you enable GMRP forward-all on a port, a copy of all multicast traffic that is registered on the
switch is forwarded to the port. We recommend enabling this option on any port that is connected to a
router. Forward-all can also forward all registered multicast traffic to a port with a network analyzer or
probe attached.
To forward a copy of all GMRP multicast packets that are registered on the switch to a port, perform this
task in privileged mode:
Task
Enable the GMRP forward-all option on a switch port. set gmrp fwdall enable mod_num/port_num

Console> (enable) set gmrp fwdall enable 1/1
GMRP Forward All groups option enabled on port 1/1.
Console> (enable)
