DESCRIPTION
Select auto to have the ONU learn multicast group membership information of any
VLANs automatically.
Select fixed to have the ONU only learn multicast group membership information
of the VLAN(s) that you specify below.
In either auto or fixed mode, the ONU 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 ONU 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.
Click Apply to save your changes to the ONU's run-time memory. The ONU 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.
Use this section of the screen to add VLANs upon which the ONU is to perform
IGMP snooping.
Enter the descriptive name of the VLAN for identification purposes.
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.
