IGMP fast leave > Explanation of IGMP fast leave

You can see the list of hosts for each port by entering the command show igmpsnooping and specifying the detail parameter:

show igmpsnooping vlan={name1..4094all} [group={multicast-ip-addressallgroups}] detail

The group parameter lets you display information for only one group or for only the All Groups port (the allgroups option).

The following example shows output when the detail parameter has been specified.
