TTL

Number of seconds before this entry ages out if not
refreshed. For static multicast 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 display igmp
receiver-table
command shows the same information as
these receiver fields.

Port

Physical port through which the WX 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.

TTL

Number of seconds before this entry ages out if the WX
does not receive a group membership message from the
receiver. For static multicast receiver entries, the TTL value
is undef. Static multicast receiver entries do not age out.

Querier information

Information about the subnet’s multicast querier. If the
querier is another WX switch, the fields described below
are applicable. If the querier is the WX itself, the output
indicates how many seconds remain until the next general
query message. If IGMP snooping does not detect a
querier, the output indicates this. The display 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 WX
does not receive a query message from the querier.

IGMP vlan member
ports

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 VLAN becomes a receiver. For example, the list can
include a MAP access port that is not configured to be in
the VLAN when a user associated with the 3Com Wireless
LAN Managed Access Point AP2750 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 display igmp statistics
command.
