-> ip multicast spoofing
To restore the IGMP spoofing to its default setting.
You can also disable IGMP spoofing on the specified VLAN by entering:
-> ip multicast vlan 2 spoofing disable
Or, as an alternative, enter:
-> ip multicast vlan 2 spoofing
To restore the IGMP spoofing to its default setting.
You can remove an IGMP spoofing entry on the specified VLAN and return to its default behavior by
entering:
-> no ip multicast vlan 2 spoofing
Enabling and Disabling the IGMP Zapping
By default, IGMP zapping (i.e., processing membership and source filter removals immediately without
waiting for the specified time period for the protocol – this mode facilitates IP TV applications looking for
quick changes between IP multicast groups) is disabled on a switch. The following subsections describe
how to enable and disable IGMP zapping by using the ip multicast zapping command.
Enabling the IGMP Zapping
To enable IGMP zapping on the system if no VLAN is specified, use the ip multicast zapping command
as shown below:
-> ip multicast zapping enable
You can also enable IGMP zapping on the specified VLAN by entering:
-> ip multicast vlan 2 zapping enable
Disabling the IGMP Zapping
To disable IGMP zapping on the system if no VLAN is specified, use the ip multicast zapping command
as shown below:
-> ip multicast zapping disable
Or, as an alternative, enter:
-> ip multicast zapping
To restore the IGMP zapping to its default setting.
You can also disable IGMP zapping on the specified VLAN by entering:
-> ip multicast vlan 2 zapping disable
Or, as an alternative, enter:
-> ip multicast vlan 2 zapping
To restore the IGMP zapping to its default setting.
