DESCRIPTION

Mode 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 five 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.

Apply

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.

Cancel

Click Cancel to begin configuring this screen afresh.

VLAN

Use this section of the screen to add VLANs upon which the Switch is to
perform IGMP snooping.

Name

Enter the descriptive name of the VLAN for identification purposes.
