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
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.
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.
