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.
VID
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.
