GMRP Service Requirement

Devices that do not support GMRP can be integrated into the Multicast addressing by means of

  • a static filter address entry on the connecting port.

  • selecting “Forward all groups”. The device enters ports with the selection “Forward all groups” in all Multicast filter entries learned via GMRP.

Prerequisite: In the Switching:Multicasts:GMRP dialog, GMRP is enabled.

Forward all groups,
Forward all unregistered groups

Forward all unregistered groups
