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.
6 In the Port Priority box, specify a priority value (0 to 255). The default is
128.
7 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
100 Mbps, full duplex—18
100 Mbps, half duplex—19
10 Mbps, full duplex aggregate link (port group)—90
10 Mbps, full duplex—95
10 Mbps, half duplex—100
Specify 0 to use the default cost for the port based on link speed.
8 To enable port fast convergence, select the PortFast checkbox.
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.
9 Click OK.
