Configuring Explicit Host Tracking

For IGMPv3, EHT is enabled by default and can be disabled on a per-VLAN basis.
To disable EHT processing on a VLAN, perform this task:
Command
Switch(config)# [no] ip igmp snooping vlan
vlan_ID explicit-tracking
This example shows how to disable IGMP EHT on VLAN 200 and to verify the configuration:
Switch# configure terminal
Switch(config)# no ip igmp snooping vlan 200 explicit-tracking
Switch(config)# end
Switch# show ip igmp snooping vlan 200 | include Explicit host tracking
Explicit host tracking

interface.

vlan_ID static mac_address interface
