Figure 6- 72. 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.
