IGMP Snooping |
IGMP is a protocol for IP hosts to manage their dynamic multicast group membership. The SEFOS IGMP conforms with RFC 3376 for IGMP v3 router functionality and supports the MIBs defined in draft-ietfmagma-rfc2933-update-00.txt.
6.1 IGMP Snooping Commands
The list of CLI commands for the configuration of IGS is as follows:
6.1.1 ip igmp snooping
Enables IGMP snooping in the switch or a specific VLAN. The no form of the command disables IGMP snooping in the switch or a specific VLAN.
|
Mode
|
Global Configuration Mode and Config-VLAN.
Applicable only in Config-VLAN.
|
|
Defaults
|
IGMP snooping is globally disabled, including in all VLANs.
|
|
Example
|
SEFOS(config)# ip igmp snooping
SEFOS(config-vlan)# ip igmp snooping
|
|
Notes
|
- When IGMP snooping is enabled globally, it is enabled in all the existing VLAN interfaces.
