10. SFP Information: View
the current port‟s SFP information, e.g. speed, Vendor ID,
Vendor S/N, etc.. SFP port state shows current DMI (Diagnostic monitoring interface)
temperature, voltage, TX Bias, etc..
11. DHCP Snooping:
View the DHCP learning table, etc..
12.
LLDP Status: View the TLV information sent by the connected device with LLDP-
enabled.
13. Loop Detection Status: View the Loop Detection status of each port.
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 State:
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 if any.
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
