Figure 6- 73. Spanning Tree Parameters window STP Setup Parameters tab
The STP Setup Parameters tab displays the following fields:
♦ MAX Age (Seconds) – Indicates the amount of time in seconds that the bridge waits before
discarding learned information. Identifies the timeout value used by all Bridges. This ensures
that each Bridge has a consistent value against which to test the age of stored configuration
information.
♦ Hello Time (Seconds) – Indicates the amount of time a bridge waits between CMs.
♦ Hold Time (Seconds) – Indicates the amount of time between the relaying of configuration
messages through a port. The default value is 1 second.
♦ Forward Delay (Seconds) – Indicates the amount of time that a port remains in the listening
and learning state before forwarding the traffic. This value is also used, when a topology change
has been detected and is underway, to age all dynamic entries in the Forwarding Database.
Forward Delay ensures that each Bridge uses a consistent value for the Forward Delay Timer
when changing the State of a Port to the Forwarding State.
Note: Forward Delay (Sec) in contrast to Bridge Forward Delay (Sec) is the value currently in use.
Bridge Forward Delay (Sec), Bridge Max Age (Sec), and Bridge Hello Time (Sec) are the values
that this bridge and all others use when the bridge becomes the root.
Spanning Tree Port Table
The Spanning Tree Port Table allows network managers to edit the port states and parameters for the
STP managed ports, and displays the port's current status.
To display the Spanning Tree Port Table:
♦ Select Bridge > Spanning Tree > Spanning Tree Port Table. The Spanning Tree Port Table
opens:
