The IGMP Snooping can constrain the multicast on the Layer 2 Ethernet switch to manage and control multicast groups. Through the multicast forwarding, resources utilization can be improved. Through limitations on user access, the network security is improved.
Prerequisites
Applies to the 11LEX4, 11LEM24, TBE, L4G board of the OptiX OSN 8800 T16(NA), OptiX OSN 8800 T32(NA), OptiX OSN 8800 T64(NA), OptiX OSN 6800A and OptiX OSN 3800A.
Applicable to the LEM18 board of the OptiX OSN 1800(NA).
The Ethernet LAN service must be created successfully.
Procedure
- In the NE Explorer, select an Ethernet data board and choose from the Function Tree.
- Click the Enable IGMP Snooping Protocol tab. Click Query.
- Select the VB that requires the IGMP Snooping protocol to be enabled. Select Enabled from the Protocol Enable drop-down list.
- Enabled: If the IGMP Snooping protocol is enabled, the equipment begins to perform the learning and aging of the router port and multicast group. Then, the multicast services are multicast in corresponding multicast groups.
- Disabled: If the IGMP Snooping protocol is disabled, the equipment stops learning and aging the router port and multicast group, and deletes all the learned dynamic multicast groups and router ports.
- Click Apply.
