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
VLANs 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 SWITCHING > Multicast > 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.
You must also enable IGMP snooping in the SWITCHING > Multicast > IPv4 Multicast > IGMP
Snooping 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.
