Static Router Ports Entry

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.
A router port has the following behavior:
•
All IGMP Report packets will be forwarded to the router port.
•
IGMP queries (from the router port) will be flooded to all ports.

Description
This is the VLAN ID that, along with the VLAN Name, identifies the VLAN the
user wishes to modify the IGMP Snooping Settings for.
This is the VLAN Name that, along with the VLAN ID, identifies the VLAN the
user wishes to modify the IGMP Snooping Settings for.
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.
Select Enabled to implement IGMP Snooping. This field is Disabled by default.
The Fast Leave option may be enabled or disabled (default). This allows an
interface to be pruned without sending group-specific queries.
