• Review all ports belonging to STPDs.
A port can belong to only one STPD. If a port is a member of multiple VLANs, then all those VLANs
must belong to the same STPD. The Spanning Tree Port Configuration Table contains the following
fields:
Port Number—Port numbers 1 to 48 or from 1 to 50 if you have the optional XEN card installed.
Priority— The priority of the port indicates the likelihood of the port becoming the root port. The
range is 0 through 31, where 0 indicates the lowest priority. The default setting is 16.
Path Cost—Specifies the path cost of the port in this STPD. The range is 1 through 65,535. The
switch automatically assigns a default path cost based on the speed of the port, as follows:
— For a 10 Mbps port, the default cost is 100.
— For a 100 Mbps port, the default cost is 19.
— For a 1000 Mbps port, the default cost is 4.
— For a 10000 Mbps port, the default cost is 2.
STPD State—Specifies whether the Spanning Tree Protocol is enabled or disabled on the STPD.
STP Domain—The name of the STP domain.
See Figure 71 for an example of the table.
• Configure Spanning Tree ports.
Add or change the above parameters for STP ports. See Figure 72 for an example of this
