LevelOne GSW-1290 Gigabit Layer2 SNMP Switch
Figure 4- 10. Static Router Ports Settings menu
To configure a static router port(s):
1. Select the Unit containing the static router port.
2. Select the Port or Ports that will become static router ports.
3. Click
Apply to let the changes take effect.
The following parameters are listed in the Static Router Port windows.
Parameter Description
VLAN ID (VID)
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.
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 LevelOne 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
