Description Factory Default
Bridge Forward Delay (secs)
Enter the switch forward delay time, which is the period in seconds that
a bridge remains in a listening and learning state before forwarding
packets. Enter a number in the range of 4 to 30 seconds, considering
that the period needs to be greater than or equal to (Bridge Max Age /
2) + 1.
15
Spanning Tree Maximum Hops
Enter the maximum number of bridge hops; the information for a CST
instance can travel before being discarded. Enter a number in the
range of 6 to 40.
20
Dynamic Path Cost
Specify whether the path cost is automatically calculated by selecting
one of the following radio buttons:
 Disable: The path cost is not automatically calculated.
 Enable: The path cost is automatically calculated.
Disable
Extend System ID Status
Specify whether the extended system identifier is added to the bridge
priority by selecting one of the following radio buttons:
 Disable: The extended system identifier is not added to the bridge
priority.
 Enable: The extended system identifier is added to the bridge

CTS Status
Description Factory Default
Bridge Identifier
The STP bridge identifier for the Common Spanning Tree (CST) on
the switch. The identifier consists of the bridge priority and the base
(fixed) MAC address of the switch.
MAC address
Time Since Topology Change
The time that has passed since the last change of the CST topology
occurred. The time is displayed in the day-hour-minute-second
format.
day-hour-minute-second
Topology Change Count
The number of times the CST topology has changed. 0
Designated Root
The STP bridge identifier of the root bridge. The identifier consists of
the bridge priority and the base MAC address of the root bridge.
MAC address
Root Path Cost
The path cost to the designated root for the CST. 0
Root Port Identifier
The interface that provides access to the designated root for the CST. 00:00
Max Age (secs)
The timer that controls the maximum time that passes before an STP
bridge port saves its configuration BPDU.
20
Forward Delay (secs)
The value that is derived from the bridge forward delay parameter of
the STP root port.
15
Hold Time (secs)
The minimum period between the transmissions of configuration
BPDUs.
