D-Link DWS-1008 CLI Manual 462
Field Description
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 show igmp receiver-table command 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.
TTL
Number of seconds before this entry ages out if the switch 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 device, the
fields described below are applicable. If the querier is the switch 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 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.
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 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.

show igmp mrouter
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.
Syntax: show igmp mrouter [vlan vlan-id]
