Variable definitions
Use the information in the following table to use 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 your platform supports channelization for 40
Gbps ports 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. VLAN IDs 1 to
4059 are configurable. The system reserves VLAN IDs 4060 to
4094 for internal use. VLAN ID 1 is the default VLAN and you
cannot create or delete VLAN ID 1.
vrfWORD<1–16> Specifies the VRF instance by the VRF name.
vrfidsWORD<0–512> Specifies the VRF ID for which to display statistics.
