DESCRIPTION
Select auto to have the Switch learn multicast group membership
information of any VLANs automatically.
Select fixed to have the Switch only learn multicast group membership
information of the VLAN(s) that you specify below.
In either auto or fixed mode, the Switch can learn up to 16 VLANs
(including up to three VLANs you configured in the MVR screen). For
example, if you have configured one multicast VLAN in the MVR screen,
you can only specify up to 15 VLANs in this screen.
The Switch drops any IGMP control messages which do not belong to
these 16 VLANs.
Note: You must also enable IGMP snooping in the Multicast
Setting screen first.
Click Apply to save your changes to the Switch's run-time memory. The
Switch loses these changes if it is turned off or loses power, so use the
Save link on the top navigation panel to save your changes to the non-
volatile memory when you are done configuring.
Click Cancel to begin configuring this screen afresh.
Use this section of the screen to add VLANs upon which the Switch is to
perform IGMP snooping.
Enter the descriptive name of the VLAN for identification purposes.
Enter the ID of a static VLAN; the valid range is between 1 and 4094.
Note: You cannot configure the same VLAN ID as in the MVR
screen.
Click Add to insert the entry in the summary table below and save your
changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the
top navigation panel to save your changes to the non-volatile memory
when you are done configuring.
Click Cancel to reset the fields to your previous configuration.
Click this to clear the fields.
This is the number of the IGMP snooping VLAN entry in the table.
