False – Indicates that each port of a device is in STP mode, whether or not a VLAN
was defined.
Figure 6- 71. Spanning Tree Parameters window Bridge Setup Parameter tab
The Bridge Setup Parameter tab displays the following fields:
♦ Bridge Priority – Identifies the bridge priority and is part of the bridge identifier. The bridge
identifier is 8 octets long, and the two most significant octets indicate the bridge priority. The
bridge with the lowest value is the root.
♦ Bridge Max Age (Seconds) – Indicates the amount of time a bridge waits before implementing
a topological change. The possible values are 6-40 seconds. The default is 20 seconds. This
parameter is configured on all the bridges participating in the STP, but only the one belonging to
the elected
♦ Bridge Hello Time (Seconds) – Indicates the amount of time a root bridge waits between
configuration messages. The possible values are 1-10 seconds. The default is 2 seconds.
Lengthening the Bridge Hello Time lowers the overhead time of the Spanning Tree Protocol (STP).
♦ Bridge Forwarding Delay (Seconds) – Indicates the amount of time a bridge remains in a
listening and learning state before forwarding packets. The possible values are 4-30 seconds.
Bridge Forward Delay is also used when a topology change is detected. Bridge Forward Delay
ensures that Bridges use a consistent value for the Forward Delay Timer when changing the Port
State to forwarding. The default is 15 seconds.
