Description
This is the VLAN ID that, along with the VLAN Name, identifies the VLAN for which to
modify the IGMP Snooping Settings.
This is the VLAN Name that, along with the VLAN ID, identifies the VLAN for which to
modify the IGMP Snooping Settings.
The Query Interval field is used to set the time (in seconds) between transmitting
IGMP queries. Entries between 1 and 65535 seconds are allowed. Default = 125.
This determines the maximum amount of time in seconds allowed before sending an
IGMP response report. The Max Response Time field allows an entry between 1 and
25 (seconds). Default = 10.
Adjust this variable according to expected packet loss. If packet loss on the VLAN is
expected to be high, the Robustness Variable should be increased to accommodate
increased packet loss. This entry field allows an entry of 1 to 255. Default = 2.
This field specifies the maximum amount of time between group-specific query
messages, including those sent in response to leave group messages. Default = 1.
This is the maximum amount of time in seconds allowed for a host to continue
membership in a multicast group without the Switch receiving a host membership
report. Default = 260.
This is the maximum amount of time in seconds a route is kept in the forwarding table
without receiving a membership report. Default = 260.
This specifies the maximum amount of time in seconds between the Switch receiving
a leave group message from a host, and the Switch issuing a group membership
query. If no response to the membership query is received before the Leave Timer
expires, the (multicast) forwarding entry for that host is deleted.
Choose Enabled to enable transmitting IGMP Query packets or Disabled to disable.
The default is Disabled.
This read-only field describes the behavior of the router for sending query packets.
Querier will denote that the router is sending out IGMP query packets. Non-Querier
will denote that the router is not sending out IGMP query packets. This field will only
read Querier when the Querier State and the State fields have been Enabled.
Select Enabled to implement IGMP Snooping. This field is Disabled by default.
