Field

Description

 

Number of seconds before this entry ages out if not refreshed. For static multicast

TTL

router entries, the time-to-live (TTL) value is undef. Static multicast router entries do

 

not age out.

Group

IP address of a multicast group. The show igmp receiver-tablecommand shows the

same information as these receiver fields.

 

 

 

Port

Physical port through which the switch can reach the group’s receiver.

 

 

Receiver-IP

IP address of the client receiving the group.

 

 

Receiver-MAC

MAC address of the client receiving the group.

 

 

 

Number of seconds before this entry ages out if the switch does not receive a group

TTL

membership message from the receiver. For static multicast receiver entries, the TTL

 

value is undef. Static multicast receiver entries do not age out.

 

Information about the subnet’s multicast querier. If the querier is another device, the

 

fields described below are applicable. If the querier is the switch itself, the output

Querier information

indicates how many seconds remain until the next general query message. If IGMP

 

snooping does not detect a querier, the output indicates this. The show igmp querier

 

command shows the same information.

 

 

Querier for vlan

VLAN containing the querier. Information is listed separately for each VLAN.

 

 

Querier-IP

IP address of the querier.

 

 

Querier-MAC

MAC address of the querier.

 

 

TTL

Number of seconds before this entry ages out if the switch does not receive a query

message from the querier.

 

 

Physical ports in the VLAN. This list includes all network ports configured to be in the

 

VLAN and all ports MSS dynamically assigns to the VLAN when a user assigned to the

IGMP vlan member ports

VLAN becomes a receiver. For example, the list can include an AP access port that is

not configured to be in the VLAN when a user associated with the access point on that

 

 

port becomes a receiver for a group. When all receivers on a dynamically added port

 

age out, MSS removes the port from the list.

 

 

IGMP static ports

Static receiver ports.

 

 

IGMP statistics

Multicast message and packet statistics. These are the same statistics displayed by

the show igmp statistics command.

Displays the multicast routers in a switch’s subnet, on one VLAN or all VLANs. Routers are listed separately for each VLAN, according to the port number through which the switch can reach the router.
