To Add/Modify to the table or Delete from the table, check the

desired option button, enter a value from 1 to 2047 in the VLAN

ID field, enter a value between 30 and 999 in the Age-out Timer

field, enable or disable the IGMP Status control, and then click

Apply.

The information above is described as follows:

♦ Add/Modify to the table Allows you to create or edit an

entry for the table.

♦ Delete from the table Allows you to delete an IGMP

entry from the table.

♦ Age-out Timer Specify the time in seconds since the

Switch last received an IGMP query from a multicast

server.

♦ IGMP Status Set the IGMP Snooping status to Disabled

or Enabled. If Enabled, this Switch forwards traffic only to

the ports that request multicast traffic. It prevents the

Switch from broadcasting traffic to all ports and possibly

harming network performance.

VLAN

VLAN mode allows you to construct a port group as well as to

reduce traffic. When you send a broadcast or multicast, only the

port member can see the packet.
