State (Read-Only)
There are five states that can display in this field. These states are
described as follows:
Disabled: Management disabled this interface. No traffic is received or
forwarded while the interface is disabled.
Learning: The switch in Learning State is looking at Bridge Protocol Data
Units (BPDUs) to determine the current network topology (during
start-up or after being deleted), or when the Spanning Tree Algorithm
detects a network topology change.
Listening: The switch is not adding information to the Transparent
Database. The switch is monitoring BPDU traffic while preparing to
move from the learning to the forwarding state.
Forwarding: The switch is operating and this interface is forwarding
traffic.
Standby: This interface does not forward any traffic through the switch
because a loop condition is detected by the STA.
Status (Toggle)
Allows you to disable or enable a port by setting the status of the listed
interface to either ENABLED or DISABLED. To set the port status, refer
to Section 5.10.3.
5.10.1 Setting the STA
The Spanning Tree Algorithm (STA) setting allows you to set the method
that the switches use to decide which is the controller (Root) switch when
two or more switches are in parallel. The available selections are IEEE,
DEC, and NONE.
To set the STA, proceed as follows:
1. Use the arrow keys to highlight the Type of STA field.
2. Use the SPACE bar to step to the appropriate setting of IEEE, DEC,
or NONE.
3. Use the arrow keys to highlight the SAVE command at the bottom of
the screen.
