VLAN ID Dis
plays the VLAN ID.
Dynamic Port List Displays router ports that have been dynamically configured.
Forbidden Port List Designates a range of ports as being disconnected to multicast-
enabled routers. Ensure that the forbidden router port will not
propagate routing packets out.
Static Port List Designates a range of ports as being connected to multicast-
enabled routers. Ensure that all the packets will reach the
multicast-enabled router.

Multicast Filtering
When multicast filtering is enabled, unknown multicast packets (did not learn by IGMP and MLD)
will be dropped, and the multicast packets already learnt by IGMP/MLD will forward as multicast
forwarding table.
When multicast filtering is disabled, unknown multicast packets (did not learn by IGMP and MLD)
will be flooded, and the multicast packets already learnt by IGMP/MLD will forward as multicast
forwarding table.
State To set multicast filtering as enabled or disabled. Default is disabled.

Jumbo Frame
Ethernet has used the 1500 byte frame size since its inception. Jumbo frames are network-layer
PDUs that have a size much larger than the typical 1500 byte Ethernet Maximum Transmission
Unit (MTU) size. Jumbo frames extend Ethernet to
10240
bytes, making them large enough to carry
an
10
KB application datagram plus packet header overhead. If you intend to leave the local area
network at high speeds, the dynamics of TCP will require you to use large frame sizes.
The switch supports a jumbo frame size of up to
10240 bytes
. Jumbo frames need to be configured
to work on the ingress and egress port of each device along the end-to-end transmission path.
