The following table describes the labels in this screen.
Table 42 Advanced Application > Multicast > Multicast Setting > IGMP Snooping VLAN
LABEL 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.
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.
Add 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.
Cancel Click Cancel to reset the fields to your previous configuration.
Clear Click this to clear the fields.
