532 Section IV: Spanning Tree Protocols
Configuring MSTP Port Settings
As explained in “Ports in Multiple MSTIs” on page 507, MSTP port settings
are divided into two groups. The parameters in the first group are set just
once on a port, regardless of the number of MSTIs in which a port is a
member. These settings are:
ˆ External path cost
ˆ Point-to-point designation
ˆ Edge port designation
The procedure for setting these parameters is in “Configuring Generic
MSTP Port Settings” on page 532.
The second group of port parameters can be set independently for each
MSTI in which the port is a member. These parameters are:
ˆ Internal path cost
ˆ Priority
To set these parameters, refer to “Configuring MSTI-specific Port
Parameters” on page 534.

The Spanning Tree Configuration menu is shown in Figure 169 on
page 485.
