Path Cost 

Defines the port contribution to the root path cost. When Default Path Cost is 
disabled, you can configure it; when Default Path Cost is enabled, you can 
not configure it , and the possible field values are: 

z 

65535: Indicates Path Cost Default Values is short. This is the default 
value. 

z 

200000000: Indicates Path Cost Default Value is long. 

Port Priority 

Defines the priority value of the port. The priority value influences the port 
choice when a bridge has two ports connected in a loop. The priority value is 
between 0-240. The default is 128. 

RSTP Link Type 

Specifies whether a Point-to-Point link is established, or if the switch is 
permitted to establish a Point-to-Point link. The possible field values are: 

z 

No Change: Retains the current port status. 

z 

Auto: Enables the switch to establish automatically Point-to-Point link. 
This is the default value. 

z 

Point to Point: Indicates if a Point-to-Point link is currently established on 
the port. Ports set to Full Duplex modes are considered Point-to-Point 
port links. 

z 

Shared: Enables the switch to establish a shared link. 

 

The STP Summary Page displays the current STP parameters for all ports. 

Click Device > Spanning Tree > Summary. The STP Summary Page opens. 

Figure 3-36 STP Summary Page 

 

 

The STP Summary Page contains the following fields: 

Table 3-27 STP Summary Page item description 

STP 

Indicates if STP is enabled on the port. The possible field values are: 

z 

Enabled: Indicates that STP is enabled on the port. 

z 

Disabled: Indicates that STP is disabled on the port. 

Port Fast 

Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for 
a port, the port is automatically placed in the Forwarding state when the port 
link is up. Fast Link optimizes the STP protocol convergence. STP 
convergence takes 30 seconds and is not dependent on the number of 
switches in the network.
