IGMP
This chapter shows you how to configure IGMP.
25.1 IGMP Overview
IGMP (Internet Group Management Protocol) is a session-layer protocol used to establish
membership in a multicast group - it is not used to carry user data. Refer to RFC 1112 and RFC
2236 for information on IGMP versions 1 and 2 respectively.
The Switch supports IGMP version 1 (IGMP-v1), version 2 (IGMP-v2) and version 3
(IGMP-v3). At start up, the Switch queries all directly connected networks to gather group
membership. After that, the Switch periodically updates this information.
25.2 Configuring IGMP
Click IP Application > IGMP in the navigation panel to display the screen as shown next.
Each entry in the table is automatically created when you configure a new IP domain in the IP
Setup screen (refer to
Section 7.6 on page 78 ).
