Current Port Status - Specifies whether the port is currently operational or non-operational. Re-Activate Port - Reactivates a port if the port has been disabled through the locked port security option. Operational Status - The port operational status. Possible field values are: Suspended - The port is currently active, and is currently not receiving or transmitting traffic. Active - The port is currently active and is currently receiving and transmitting traffic. Disable - The port is currently disabled, and is not currently receiving or transmitting traffic. Admin Speed - The configured rate for the port. The port type determines what speed setting options are available. Admin speed can only be designated when auto negotiation is disabled on the configured port. Current Port Speed - The actual currently configured port speed (bps). Admin Duplex - The port duplex mode can be either Full or Half. Full indicates that the interface supports transmission between the device and its link partner in both directions simultaneously. Half indicates that the interface supports transmission between the device and the client in only one direction at a time. Current Duplex Mode - The currently configured port duplex mode. Auto Negotiation - Enables Auto Negotiation on the port. Auto Negotiation is a protocol between two link partners that enables a port to advertise its transmission rate, duplex mode and flow control abilities to its partner. Current Auto Negotiation - The currently configured Auto Negotiation setting. Back Pressure - Enables Back Pressure mode on the port. Back Pressure mode is used with Half Duplex mode to disable ports from receiving messages. Current Back Pressure - The currently configured Back Pressure setting. Flow Control - Enables or disables flow control or enables the auto negotiation of flow control on the port. Operates when port is in Full duplex mode. Current Flow Control - The currently configured Flow Control setting. MDI/MDIX - Allows the device to decipher between crossed and uncrossed cables. Hubs and switches are deliberately wired opposite the way end stations are wired, so that when a hub or switch is connected to an end station, a straight through Ethernet cable can be used, and the pairs are match up properly. When two hubs/switches are connected to each other, or two end stations are connected to each other, a crossover cable is used ensure that the correct pairs are connected. The possible field values are: Auto - Used to automatically detect the cable type. MDI (Media Dependent Interface) - Used for end stations. MDIX (Media Dependent Interface with Crossover) - Used for hubs and switches. Configuring Device Information 215

Configuring Device Information
215
Current Port Status
— Specifies whether the port is currently operational or non-operational.
Re-Activate Port
— Reactivates a port if the port has been disabled through the locked port
security option.
Operational Status
— The port operational status. Possible field values are:
Suspended
— The port is currently active, and is currently not receiving or transmitting
traffic.
Active
— The port is currently active and is currently receiving and transmitting traffic.
Disable
— The port is currently disabled, and is not currently receiving or transmitting traffic.
Admin Speed
— The configured rate for the port. The port type determines what speed setting
options are available. Admin speed can only be designated when auto negotiation is disabled on the
configured port.
Current Port Speed
— The actual currently configured port speed (bps).
Admin Duplex
— The port duplex mode can be either
Full
or
Half
.
Full
indicates that the
interface supports transmission between the device and its link partner in both directions
simultaneously.
Half
indicates that the interface supports transmission between the device and the
client in only one direction at a time.
Current Duplex Mode
— The currently configured port duplex mode.
Auto Negotiation
— Enables Auto Negotiation on the port. Auto Negotiation is a protocol
between two link partners that enables a port to advertise its transmission rate, duplex mode and
flow control abilities to its partner.
Current Auto Negotiation
— The currently configured Auto Negotiation setting.
Back Pressure
— Enables Back Pressure mode on the port. Back Pressure mode is used with Half
Duplex mode to disable ports from receiving messages.
Current Back Pressure
— The currently configured Back Pressure setting.
Flow Control
— Enables or disables flow control or enables the auto negotiation of flow control on
the port. Operates when port is in
Full
duplex mode.
Current Flow Control
— The currently configured Flow Control setting.
MDI/MDIX
— Allows the device to decipher between crossed and uncrossed cables.
Hubs and switches are deliberately wired opposite the way end stations are wired, so that when a
hub or switch is connected to an end station, a straight through Ethernet cable can be used, and
the pairs are match up properly. When two hubs/switches are connected to each other, or two end
stations are connected to each other, a crossover cable is used ensure that the correct pairs are
connected. The possible field values are:
Auto
— Used to automatically detect the cable type.
MDI (Media Dependent Interface)
— Used for end stations.
MDIX (Media Dependent Interface with Crossover)
— Used for hubs and switches.
