4.9.2 The Global STP
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 4-46 Global 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
Values
This specifies the method used to assign default path costs to STP ports. The
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.
