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:
 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
node is operating at a fixed duplex mode of full-duplex.
To avoid this problem when connecting an end node
with a fixed duplex mode of full-duplex to a switch port,
disable Auto-Negotiation on the port and set the port’s
speed and duplex mode manually.
 The only valid setting for an optional SFP port is Auto-
Negotiation.
