Figure 7- 33. Router Port window (Modify)
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 MLD
multicast router is attached.
VLAN Name This is the name of the VLAN where the MLD multicast router is attached.
Port Settings Ports on the Switch that will have a multicast router attached to them. There are three options
for which to configure these ports:
None
– Select this option to not set these ports as router ports
Static
– Select this option to designate a range of ports as being connected to a multicast-
enabled router. This command will ensure that all packets with this router as its destination will
reach the multicast-enabled router.
Forbidden
– Select this option to specify the port as not being a member of the VLAN and that
the port is forbidden from becoming a member of the VLAN dynamically.
Click
Apply
to implement the new settings.
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.
802.1Q MSTP
Multiple Spanning Tree Protocol, or MSTP, is a standard defined by the IEEE community that allows multiple VLANs to be
mapped to a single spanning tree instance, which will provide multiple pathways across the network. Therefore, these MSTP
configurations will balance the traffic load, preventing wide scale disruptions when a single spanning tree instance fails. This will
allow for faster convergences of new topologies for the failed instance. Frames designated for these VLANs will be processed
quickly and completely throughout interconnected bridges utilizing any of the three spanning tree protocols (STP, RSTP or
MSTP).
