The following table describes the labels in this screen.

22.3.3 IGMP Filtering Profile

An IGMP filtering profile specifies a range of multicast groups that clients connected to the Switch
are able to join. A profile contains a range of multicast IP addresses which you want clients to be
able to join. Profiles are assigned to ports (in the IGMP Snooping screen). Clients connected to
those ports are then able to join the multicast groups specified in the profile. Each port can be
assigned a single profile. A profile can be assigned to multiple ports.

Click Advanced Application > Multicast > IPv4 Multicast in the navigation panel. Click the
IGMP Snooping link and then the IGMP Filtering Profile link to display the screen as shown.

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 > IPv4 Multicast > IGMP

Snooping

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.

Note: You cannot configure the same VLAN ID as in the

MVR

screen.

Add

Click this to create a new entry or to update an existing one.

This saves 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 Clear to reset the fields to the factory defaults.
