The following parameters may be viewed or modified:
Parameter Description
VLAN ID
This is the VLAN ID that, along with the VLAN name, identifies the VLAN
which the user wishes to modify the IGMP Snooping Settings for.
VLAN Name
This is the VLAN Name that, along with the VLAN ID, identifies the
VLAN which the user wishes to modify the IGMP Snooping Settings for.
Query Interval
The Query Interval field is used to set the time (in seconds) between
transmitting IGMP queries. Entries between 1 and 9,999 seconds are
allowed. Default = 125.
Max Response Time
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.
Robustness Variable
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.
Last Member Query
Interval
Specifies the maximum amount of time between group-specific query
messages, including those sent in response to leave group messages.
Default = 1.
Host Timeout
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.
Route Timeout
This is the maximum amount of time in seconds a route is kept in the
forwarding table without receiving a membership report. Default = 260.
Leave Timer
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.
Querier State
Choose Enabled to enable transmitting IGMP Query packets or Disabled
to disable. The default value is Disabled.
State
Select Enabled to implement IGMP Snooping. This field is Disabled by
default.
Click Apply to implement the new settings, Click the Show All IGMP Group Entries link to return to the
Current IGMP Snooping Group Entries window.
Static Router Ports
A static router port is a port that has a multicast router attached to it. Generally, this router would have a
connection to a WAN or to the Internet. Establishing a router port will allow multicast packets coming from the
router to be propagated through the network, as well as allowing multicast messages (IGMP) coming from the
network to be propagated to the router.
