Using Multicast Manager
Multicast Manager displays the following multicast protocols and groups
supported on the devices discovered in the network topology:
• Layer 2 IGMP Snoop
• Layer 3 IGMP
• DVMRP
• Multicast routes
The last group displayed is the Multicast Groups. Multicast groups are defined by
a multicast address and are listed in Multicast Manager by their multicast address.
To open a new table, double-click the multicast address listed below the protocol.
Viewing IGMP Snoop groups
IGMP Snooping works at layer 2 in the network. You configure IGMP Snooping
using Device Manager. All devices supported by Optivity Switch Manager can be
configured for IGMP Snooping.
To view the information associated with IGMP Snoop groups:
The IGMP Snoop Table opens with the General tab displayed (Figure 58) .
Select a device listed under the IGMP Snoop folder.
Note: If a BayStack switch or a Business Policy Switch 2000 is selected,
only the General tab is displayed.
