D-Link DGS-3324SR Layer 3 Stackable Gigabit Ethernet Switch
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 the 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,
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 page (shown above) displays all of the current entries to the Switch's
static router port table. To add or modify an entry, click the Modify button. This will open the Static Router
Ports Settings page, as shown below.
The following parameters can be set:
