5.4.5.4.4 Overriding IGMP Snooping Configuration
Overriding the Network Configuration
Internet Group Management Protocol (IGMP) is a protocol to establish and maintain multicast group memberships to interested
members. Multicasting allows a computer on a network to send content to multiple computers who have registered to receive
the content. IGMP Snooping is the term for listening to IGMP traffic between an IGMP host and routers in the network to
maintain a map of the links that require multicast streams. Multicast traffic is filtered out for those links which do not require
them.
To configure IGMP Snooping:
1. Select the Configuration tab from the Web UI.
2. Select Device Overrides from the Device menu to expand it into sub menu options.
3. Select a target device from the device browser in the lower, left-hand, side of the UI.
4. Select Network to expand its sub menu options.
