Configuring Switch Information 211
– Disable—Disables auto negotiation on the port. This is the default value.
– Current Auto Negotiation—Indicates the Auto Negotiation operational status.
• Back Pressure—Enables Back Pressure mode on the device. Back Pressure mode is
used with Half Duplex mode to disable ports from receiving messages. When Back
Pressure is enabled, Head-of-Line blocking is not operational, even if it is set to enable.
• The possible field values are:
– Enable—Enables back pressure on the port.
– Disable—Disable back pressure on the port. This is the default value.
– Current Back Pressure—Indicates the back pressure operational status.
• Flow Control—Indicates if Flow Control is enabled on the port. Flow control is
enabled if the device is in Duplex mode. In addition, when Flow Control is enabled,
Head-of-Line is disabled on the selected port. When Flow Control is enabled, Head-
of-Line blocking is not operational, even if it is set to enable. The possible field values
are:
– Enable—Indicates that Flow Control is enabled on the device.
– Disable—Indicates that Flow Control is disabled on the device. This is the
default value.
– Current Flow Control—Indicates the Flow Control operational status.
– Auto-negotiation—Enables auto negotiation of Flow Control on the port.
– Tx Only—Enables auto negotiation for egress ports.
– Rx Only —Enables auto negotiation for ingress ports.
• MDI/MDIX—Allows the device to decipher between crossed and uncrossed cables.
Hubs and switches are deliberately wired the opposite 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 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 to make sure that the correct pairs are connected. The standard cable
wirings are:
– Media Dependent Interface with Crossover (MDIX) for hubs and switches
– Media Dependent Interface (MDI) for end stations
NOTE: Auto MDIX does not operate on FE ports when auto negotiation is disabled.
