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.
