CLI – This command enables loopback detection for port 1/5, configures automatic
release-mode, and enables SNMP trap notification for detected loopback BPDUs.
Displaying Global Settings for STA
You can display a summary of the current bridge STA information that applies to the
entire switch using the STA Information screen.
Field Attributes
• Spanning Tree State – Shows if the switch is enabled to participate in an
STA-compliant network.
• Bridge ID – A unique identifier for this bridge, consisting of the bridge priority, the
MST Instance ID 0 for the Common Spanning Tree when spanning tree mode is
set to MSTP (page 3-194), and MAC address (where the address is taken from the
switch system).
• Max Age – The maximum time (in seconds) a device can wait without receiving a
configuration message before attempting to reconfigure. All device ports (except
for designated ports) should receive configuration messages at regular intervals.
Any port that ages out STA information (provided in the last configuration
message) becomes the designated port for the attached LAN. If it is a root port, a
new root port is selected from among the device ports attached to the network.
(References to “ports” in this section mean “interfaces,” which includes both ports
and trunks.)
• Hello Time – Interval (in seconds) at which the root device transmits a
configuration message.
