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

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

separately for each VLAN.

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.
