DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
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 Snooping folder and the click on the Static Router Ports Settings link to open the Static Router Port Settings
window, as shown below.
Figure 7- 14. Static Router Ports Settings window
The Static Router Ports Settings page (shown above) 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 following window:
Figure 7- 15. Static Router Ports Settings - Edit window
The following parameters can be set:
Parameter Description
VID (VLAN ID)
This is the VLAN ID that, along with the VLAN Name, identifies the VLAN where the
multicast router is attached.
VLAN Name
This is the name of the VLAN where the multicast router is attached.
Member Ports
These are the ports on the Switch that will have a multicast router attached to them.
Click Apply to implement the new settings, Click the Show All Static Router Port Entries link to return to the Current Static
Router Port Entries window.
Spanning Tree
This Switch supports three versions of the Spanning Tree Protocol; 802.1d STP, 802.1w Rapid STP and MSTP. 802.1d STP will
be familiar to most networking professionals. However, since 802.1w RSTP has been recently introduced to D-Link managed
Ethernet switches, a brief introduction to the technology is provided below followed by a description of how to set up 802.1d STP
and 802.1w RSTP.
802.1w Rapid Spanning Tree
The Switch implements two versions of the Spanning Tree Protocol, the Rapid Spanning Tree Protocol (RSTP) as defined by the
IEEE 802.1w specification and a version compatible with the IEEE 802.1d STP. RSTP can operate with legacy equipment
implementing IEEE 802.1d, however the advantages of using RSTP will be lost.
