CAR is supported; a 1M step limitation is conducted to the 100M port, and a 8M step limitation is conducted to the gigabit port. Broadcast control The broadcast storm is constrained. When the threshold value for controlling the broadcast storm is reached, the broadcast packets are stopped from being forwarded. Multicast control IGMP Snooping, automatic multicast snooping Multicast routing IGMP v1/v2/v3 PIM-SM &PIM-DM Interface binding Each port binding group contains up to 8 ports, and 6 port binding groups are supported meanwhile.
