Variable Definitions

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


Variable	Value
count	Displays the number of entries in the IGMP group.
group `<A.B.C.D>`	Specifies the address of the IGMP group.
member-subnet {default\| `<A.B.C.D>`}]	Specifies the IP address and mask of the IGMP member.
vrf `WORD<1–16>`	Specifies the VRF name.
vrfids `WORD<0–512>`	Specifies the VRF ID.

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


Variable	Value
detail [port `{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`\|vlan `<1-4059>`\|vrf`WORD <1–16>`\|vrfids`WORD <0–255>`]	Use the detail parameter to show IGMPv3–specific data. For data related to a specific interface use the following: port`{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}` — Specifies the port list. vlan `<1-4059>`— Specifies the VLAN. 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 name. vrfids `WORD<0–255>` — Specifies the VRF ID.
tracked-members	Use the tracked-members parameter to view all the tracked members for a specific group.
vrf `WORD<1–16>`	Specifies the VRF name.
vrfids `WORD<0–512>`	Specifies the VRF ID.

The following table defines parameters for the show ip igmp group group <A.B.C.D> tracked-members command.


Variable	Value
member-subnet {default\| `<A.B.C.D>`}]	Specifies the IP address and mask of the IGMP member.
port `{slot/port[/sub-port] [-slot/port[/sub-port]] [,...]}`	Specifies the port list.
source-subnet`<A.B.C.D/X>`	Specifies the source IP address and the subnet mask.
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 name.
