4.5.1 Switch Port State
In order to view the real-time port status of the Managed Switch, select Switch Port State
from the Switch Monitor menu and then the following screen page appears.
Port Number: The number of the port.
Media Type: The media type of the port, either TX or Fiber.
Port Sate: This shows each port’s state which can be D (Disabled), B/L (Blocking/Listening),
L (Learning) or F (Forwarding).
Disabled: A port in this state does not participate in frame relay or the operation of
the Spanning Tree Algorithm and Protocol.
Blocking: A port in this state does not participate in frame relay; thus, it prevents
frame duplication arising from multiple paths existing in the active topology of Bridged
LAN.
Learning: A port in this state prepares to participate in frame relay. Frame relay is
temporarily disabled in order to prevent temporary loops, which may occur in a
Bridged LAN during the lifetime of this state as the active topology of the Bridged
LAN changes. Learning is enabled to allow information to be acquired prior to frame
relay in order to reduce the number of frames that are unnecessarily relayed.
Forwarding: A port in this state participates in frame relay. Packets can be forwarded
only when port state is forwarding.
Link State: The current link status of the port, either up or down.
Speed (Mbps): The current operation speed of ports, which can be 10M, 100M or 1000M.
Duplex: The current operation Duplex mode of the port, either Full or Half.
Flow Control: The current state of Flow Control, either on or off
