The Global STP screen (see figure 4-46) contains parameters for enabling STP on the device.

Global Setting Spanning Tree State, which indicates if STP is enabled on the device.

Figure 4-46Global STP screen

The page contains the following fields:

„Global Setting

•STP Operation Mode This indicates the STP mode by which STP is enabled on the device. The possible field values are:

•Classic STP, where enables Classic STP on the device. This is the default value.

•Rapid STP, where enables Rapid STP on the device.

•Multiple STP, where enables Multiple STP on the device.

• BPDU Handling

This determines how BPDU packets are managed when STP is disabled on the

 

port/ device. BPDUs are used to transmit spanning tree information. The possible

 

field values are:

 

• Filtering, where filters BPDU packets when spanning tree is disabled on an

 

interface. This is the default value.

 

• Flooding, where floods BPDU packets when spanning tree is disabled on an

 

interface.

• Path Cost Default

This specifies the method used to assign default path costs to STP ports. The

Values

possible field values are:

• Short, specifies 1 through 65,535 range for port path costs.

 

 

This is the default value.

 

• Long, specifies 1 through 200,000,000 range for port path costs. The default

 

path costs assigned to an interface varies according to the selected method.
