.
Port # (Read-Only)
Lists each bridge port on the module. If the number of ports is greater
than eight, then the additional ports are listed on subsequent screens.
MAC Address (Read-Only)
Displays the hardware MAC address assigned to each listed port.
State (Read-Only)
Disabled: Management disabled this interface. No traffic is received or
forwarded while the interface is disabled.
Listening: The bridge is not adding information to the Transparent
Database. The bridge is monitoring BPDU traffic while preparing to
move from the learning to the forwarding state.
Learning: The switch is learning the network address of this interface.
The bridge enters the learning state when the Transparent Database is
created (during start-up or after being deleted), or when the Spanning
Tree Algorithm detects a network topology change.
Forwarding: The bridge is on line and this interface is forwarding traffic.
Blocking: This interface will not forward any traffic through the bridge
because a loop condition has been detected by the STA.
Status (Toggle)
Allows the user 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 6.19.3

6.19.1
Setting the STA
The Spanning Tree Algorithm (STA) setting allows the user 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:
