Enabling PIM SM snooping on a VLAN
This command enables PIM SM traffic snooping. The PIM SM traffic snooping feature assumes that the network has routers that are running PIM SM.
NOTE
The device must be in passive mode before it can be configured for PIM SM snooping.
To disable the feature, enter the no ip
device(config)#no ip
If you also want to disable IP multicast traffic reduction, enter the no ip multicast command.
device(config)#no ip multicast
Syntax: [no] ip
Enabling PIM SM snooping on a VLAN
You can enable PIM SM snooping for a specific VLAN. For example, the following commands enable PIM SM snooping on VLAN 20.
device(config)#vlan 20
Syntax: [no] multicast
Disabling PIM SM snooping on a VLAN
When PIM SM snooping is enabled globally, you can still disable it for a specific VLAN. For example, the following commands disable PIM SM snooping for VLAN 20. This setting overrides the global setting.
device(config)#vlan 20
Syntax: [no] multicast
