Configuring Spanning Tree Port Information
You can change the STP cost and priority of an individual port. You can
also enable port fast convergence.
Port fast convergence bypasses both the listening and learning stages and
immediately places a port in the forwarding state. Use port fast
convergence on network ports that are directly connected to servers,
hosts, or other MAC stations.
Do not use port fast convergence on ports connected to other bridges.
To configure STP port information:
1 In the Create VLAN wizard, click Spanning Tree Port Setup. The
Spanning Tree Port Setup page appears.
2 Select the port whose STP information you want to modify.
3 Click Modify. The Modify Port dialog box appears.
4 To enable spanning tree packet processing (Tx/Rx) on that port, make
sure Enabled is selected. This is the default.
To disable this feature, clear Enabled. If you disable spanning tree packet
processing on the port, the following might happen:
 If STP is enabled on the VLAN, spanning tree packets are dropped at
the port.
 If STP is disabled on the VLAN, spanning tree packets are forwarded
transparently through the VLAN to and from that port.
5 In the Port Priority box, specify a priority value (0 to 255). The default is
128.
6 In the Path Cost box, specify a value (0 to 65,535) for the cost. The
default depends on the port speed and link type:
 1000 Mbps, full duplex aggregate link (port group)—3
 1000 Mbps, full duplex—4
 100 Mbps, full duplex aggregate link (port group)—15
