VOLKTEK NSH-5509 MANAGED 8-PORT 10/100 + 1-PORT 100-FX SWITCH
8.4 Bridge Menu
The Bridge menu is used for configuring the Spanning Tree Algorithm and Xpress Ring
settings, as well as the traffic class priority threshold and the address aging time.
Xpress Ring offers a very fast link-failure recovery time of 50ms, user must select the
role of the Switch (arbiter or forward) and which two ports will be part of the Xpress Ring
network.
The Spanning Tree Algorithm is used for detecting and disabling network loops, and to
provide backup links between switches, bridges or routers. This allows the switch to
communicate and interact with other bridging devices (i.e. STA-compliant devices) in a
network to ensure that only one route exists between any two stations, and it provides
redundant or backup links that automatically take over when a primary link goes down.
8.4.1 Bridge Configuration (Enable / Disable RSTP, etc.)
Select the appropriate mode (protocol) for your network implementation, then click
“Apply” to implement newly entered information, or click “Undo” to restore previously
saved configurations.
Parameter Description
Disable
RSTP (802.1W)
Xpress Ring
Port 1~9
Don’t enable RSTP or Xpress Ring
Enable Rapid Spanning Tree Protocol
Enable Xpress Ring function, redundant link with fastest recovery time: less
than 50ms
Enable (V): This port participates in the STP/RSTP algorithm execution of
the Switch when RSTP (802.1W) is enabled.
Disable (_): This port doesn't participate in the STP/RSTP algorithm
execution of the Switch when RSTP (802.1W) is enabled.
