Determine the protocol configured on the added VLAN:

show ip igmp interface [gigabitethernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}][vlan <1-4059>][vrf WORD<1–16>] [vrfids WORD<0–512>]

The protocol displays under the Mode column of the command output.

Variable Definitions

The following table defines parameters for the show ip igmp interface command.


Variable	Value
gigabitethernet`{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`	Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port). If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
vlan`<1-4059>`	Specifies the VLAN ID in the range of 1 to 4059. By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998. VLAN ID 1 is the default VLAN and you cannot create or delete VLAN ID 1.
vrf`WORD<1–16>`	Specifies the VRF instance by the VRF name.
vrfids`WORD<0–512>`	Specifies the VRF ID for which to display statistics.
