Parameter
Description
Spanning Tree Protocol
Enable this parameter to participate in an STP-compliant network.
Bridge Priority
Device priority is used in selecting the root device, root port, and
designated port. The device with the highest priority becomes the STP root
device. However, if all devices have the same priority, the device with the
lowest MAC address will then become the root device.
Default: 32,768
Range: 0 - 65535.
Remember that the lower the numeric value, the higher the priority.
Hello Time
Time interval (in seconds) at which the root device transmits a configuration
message.
Default: 2
Minimum: 1.
Maximum: lower of 10 or [(Max. Message Age/2) - 1]
Max Age
The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports
(except for designated ports) should receive configuration messages at
regular intervals. Any port that ages out STP information (provided in the
last configuration message) becomes the designated port for the attached
LAN. If it is a root port, a new root port is selected from among the device
ports attached to the network.
Default: 2
Minimum: higher of 6 or [2x(Hello Time + 1)]
Maximum: lower of 40 or [2x(Forward Delay - 1)]
Forward Delay
The maximum time (in seconds) the root device will wait before changing
states (i.e., listening to learning to forwarding). This delay is required
because every device must receive information about topology changes
before it starts to forward frames. In addition, each port needs time to listen
for conflicting information that would make it return to a blocking state;
otherwise, temporary data loops might result.
Default: 15
Maximum: 30
Minimum: higher of 4 or [(Max. Message Age/2)+1]
