DESCRIPTION

Active

Select this check box to enable IGMP on the Switch.

 

Note: You cannot enable both IGMP snooping and IGMP at the same

 

time. Refer to Section 24.4 on page 234 for more information on

 

IGMP snooping.

 

 

Unknown

Specify the action to perform when the Switch receives an unknown

Multicast

multicast frame. Unknown multicast frames are addressed to multicast

Frame

groups for which the Switch has not recorded any group members. Select

 

Drop to discard the frame(s). Select Flooding to send the frame(s) to all

 

ports.

 

 

Index

This field displays an index number of an entry.

 

 

Network

This field displays the IP domain configured on the Switch.

 

Refer to Section 8.6 on page 113 for more information on configuring IP

 

domains.

 

 

Version

Select an IGMP version from the drop-down list box. The choices are IGMP-

 

v1, IGMP-v2,IGMP-v3 and None.

 

Generally, if you want to enable IGMP on the Switch, you should choose

 

IGMP-v3as it is compatible with older versions. Choose an earlier version of

 

IGMP (IGMP-v2or IGMP-v1) if the multicast hosts on your network can not

 

recognize IGMP version 3 or version 2 Query messages.

 

 

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.
