CLI
– This example enables Spanning Tree Protocol and then configures
the STA parameters.
Displaying Interface Settings
The STA Port Information and STA Trunk Information pages display the
current status of ports and trunks in the Spanning Tree.
Field Attributes
•
Spanning Tree
– Shows if STA has been enabled on this interface.
•
STA Status
– Displays current state of this port within the Spanning
Tree:
-
Discarding
- Port receives STA configuration messages, but does
not forward packets.
-
Learning
- Port has transmitted configuration messages for an
interval set by the Forward Delay parameter without receiving
contradictory information. Port address table is cleared, and the port
begins learning addresses.
-
Forwarding
- Port forwards packets, and continues learning
addresses.
The rules defining port status are:
- A port on a network segment with no other STA compliant bridging
device is always forwarding.
- If two ports of a switch are connected to the same segment and there
is no other STA device attached to this segment, the port with the
smaller ID forwards packets and the other is discarding.
- All ports are discarding when the switch is booted, then some of
them change state to learning, and then to forwarding.
