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.
•
All UDP multicast packets will be forwarded to the router port. Because routers do not send IGMP reports or
implement IGMP snooping, a multicast router connected to the router port of a Layer 3 switch would not be able to
receive UDP data streams unless the UDP multicast packets were all forwarded to the router port.
A router port will be dynamically configured when IGMP query packets, RIPv2 multicast, DVMRP multicast or PIM-DM
multicast packets are detected flowing into a port.
Open the IGMP folder and the click on the Static Router Ports Entry link to open the Current Static Router Ports Entries
page, as shown below.
The Current Static Router Ports Entries window displays all of the current entries to the Switch's static router port table. To
modify an entry, click the Modify button. This will open the Static Router Ports Settings window, as shown below.
The following parameters can be set:
