PLANET WGSD-1022 - Manual (Page 51)

The page contains the following fields:
• STP 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.
• Priority Specifies the bridge priority value. When switches or bridges are running
STP, each is assigned a priority. After exchanging BPDUs, the device with
the lowest priority value becomes the Root Bridge.
The port priority value is provided in increments of 4096. For example,
4096, 8192, 12288, etc. The range is 0 to 65535.
The default value is 32768.
• Hello Time This specifies the device Hello Time. The Hello Time indicates the amount
of time in seconds a root bridge waits between configuration messages.
The default is 2 seconds. The range is 1 to 10 seconds.
• Max Age Where specifies the device Maximum Age Time. The Maximum Age Time
indicates the amount of time in seconds a bridge waits before sending
configuration messages.
The default max age is 20 seconds. The range is 6 to 40 seconds.
• Forward Delay This specifies the device forward delay time. The Forward Delay Time
indicates the amount of time in seconds a bridge remains in a listening
and learning state before forwarding packets.
The default is 15 seconds. The range is 4 to 30 seconds.
