Figure 4-16 STP Port Config screen
The page contains the following fields:
• Port#
Indicates the port or LAG on which STP is enabled
• Enable STP
which indicates if STP is enabled on the port
• Port Fast
Indicates if Fast Link is enabled on the port. If Fast Link mode is enabled for a
port, the Port State is automatically placed in the Forwarding state when the port
link is up. Fast Link optimizes the STP protocol convergence. STP convergence
can take 30-60 seconds in large networks.
• Port State
Displays the current STP state of a port. If enabled, the port state determines
what forwarding action is taken on traffic. Possible port states are:
• Disabled, indicates that STP is currently disabled on the port. The port
forwards traffic while learning MAC addresses.
• Blocking, where indicates that the port is currently blocked and cannot
forward traffic or learn MAC addresses. Blocking is displayed when Classic
STP is enabled.
• Listening, where indicates that the port is in Listening mode. The port
cannot forward traffic nor can it learn MAC addresses.
• Learning, where indicates that the port is in whose mode. The port cannot
forward traffic, however it can learn new MAC addresses.
