The meaning of the fields is as follows:
Switch Status
:
Switch status, operating or not.
Number of resets
:
Number of internal switch resets.
Port
:
Switch port identifier.
Lnk (Link)
:
Link status, established (Y) or not (N).
MDIX:
Indicates whether the switch port is exchanging (Y) the Tx and Rx pairs or not (N).
If the link isn’t established, then this value isn’t valid.
If the remote end doesn’t have an MDI/MDIX feature and the cable is pin to pin,
the port exchanges Tx and Rx pairs so a crossover cable is not required.
If the remote end doesn’t have the MDI/MDIX feature, then it uses a crossover
cable and consequently does not exchange the pairs.
If the remote end has the MDI/MDIX feature (with a crossover cable or not) the
result is undetermined. Either one of the ends can be crossed.
Autoneg complete:
Indicates if the auto-negotiation has completed or not. Whenever auto-negotiation
is disabled, this is indicated with a hyphen (‘ - ’).
Speed
:
Whenever auto-negotiation has completed or is disabled, this option indicated the
link speed in Mbps.
Duplex
:
Whenever auto-negotiation has completed or is disabled, this option indicates the
link duplex mode.
FC
:
Whenever auto-negotiation has completed or is disabled, this indicates the flow
control mode.
• N: no flow control.
• Rx: asymmetric flow control on incoming path. Pause frames are received and
dispatched, thus enabling or disabling transmission accordingly. No Pause
frames are transmitted.
• Tx: asymmetric flow control on outgoing path. Pause frames are transmitted on
congestion. Received Pause frames are ignored.
• Y: symmetric flow control, on both incoming and outgoing paths.
Auto-negotiation advertise
: Indicates the capacities advertised by the switch:
• 1000FD: switch advertises it supports links at 1Gbps in Full Duplex mode.
• 1000HD: switch advertises it supports links at 1Gbps in Half Duplex mode.
• 100FD: switch advertises it supports links at 100Mbps in Full Duplex mode.
• 100HD: switch advertises it supports links at 100Mbps in Half Duplex mode.
• 10FD: switch advertises it supports links at 10Mbps in Full Duplex mode.
• 10HD: switch advertises it supports links at 10Mbps in Half Duplex mode.
• Flow Control: switch advertises it supports flow control.
• Pause: switch advertises it supports symmetric flow control.
• Asym: switch advertises it supports asymmetric flow control.
