Figure 4- 11. Static Router Ports Settings 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.
Unit
This is the Unit ID of the switch in a switch stack for which you are creating
an entry into the switch’s static router port table.
Member Ports
There are the ports on the Switch that will have a multicast router attached
to them.

to implement them.
Configuring The Spanning Tree
The Switch supports 802.1d Spanning Tree Protocol (STP) and 802.1w Rapid Spanning Tree Protocol (RSTP).
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 802.1 d 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 IEE 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.
The IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1d STP standard. RSTP was
developed in order to overcome some limitations of STP that impede the function of some recent switching
innovations, in particular, certain Layer 3 function that are increasingly handled by Ethernet switches. The basic
function and much of the terminology is the same as STP. Most of the settings configured for STP are also used
for RSTP. This section introduces some new Spanning Tree concepts and illustrates the main differences
between the two protocols.
