Type
The port type. The port type is 10/100TX for 10/100Base-T twisted pair
ports and 1000Base-F for the SFP fiber port.
Link Status
The status of the link between the port and the end node connected to
the port. The possible values are:
Up - A valid link exists between the port and the end node.
Down - The port and the end node have not established a valid link.
Admin. Status
The operating status of the port.
You can use this parameter to enable or disable a port. You may want
to disable a port and prevent packets from being forwarded if a
problem occurs with the node or cable connected to the port. After the
problem has been fixed, you can enable the port to resume normal
operation. You can also disable an unused port to secure it from
unauthorized connections. The possible values are:
Enabled - The port is able to send and receive Ethernet frames. This is
the default setting for a port.
Disabled - The port is disabled.
Mode
The speed and duplex mode settings for the port.
You can use this parameter to set the speed and duplex mode of a
port. Possible settings are:
Auto - The port is using Auto-Negotiation to set the operating speed
and duplex mode. This is the default setting for all ports. The actual
operating speed and duplex mode of the port are displayed in
parentheses (for example, “100F”) after a port establishes a link with
an end node.
100M/Full - 100 Mbps in full-duplex mode
10M/Full - 10 Mbps in full-duplex mode
100M/Half - 100 Mbps in half-duplex mode
10M/Half - 10 Mbps in half-duplex mode
When you choose a setting, note the following:
ˆ When a twisted pair port is set to Auto-Negotiation, the default
setting, the end node should also be using Auto-Negotiation to
prevent a duplex mode mismatch. A switch port using Auto-
Negotiation defaults to half-duplex if it detects that the end node is
not using Auto-Negotiation. This can result in a mismatch if the end
