VLAN ID   Displays 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.  
 Click the Apply button   to accept the changes or the Cancel button   to discard them. 
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.  
 Click Apply to update the system settings.  
 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.
