cpe duplex

Use the cpe duplex interface configuration command to specify the duplex mode of operation for all

customer premises equipment (CPE) ports. Use the no form of this command to return to the default

setting.

cpe duplex {{auto | full | half} [port port-id]}

no cpe duplex {{auto | full | half} [port port-id]}

This command is available only on Catalyst 2950 Long-Reach Ethernet (LRE) switches.

Syntax Description

Defaults The default duplex mode is half.

Command Modes Interface configuration

Command History

Usage Guidelines Use the cpe duplex full command to set the duplex mode to full for all the CPE Ethernet ports. Use the

auto keyword to set the CPE Ethernet ports to autonegotiate, and use the half keyword to force the

duplex mode to half for all the CPE Ethernet ports.

If you do not enter the port keyword, the duplex setting is applied to all the CPE Ethernet ports. If you

enter the port port-id keywords, the setting is applied to the specified CPE Ethernet port and overrides

any global speed settings.

Use the cpe duplex full port 2 command to set the duplex mode of port 2 on a CPE device to full duplex.

If you enter both a switch-wide command, such as the cpe duplex full command, and a port-specific

commands, such as the cpe duplex full port 2 command, the switch adds both the configuration file, and

the port-specific command takes priority over the switch-wide command.

Examples This example show how to set the CPE device to autonegotiate:

Switch# configure terminal

Switch(config)# interface longreachethernet0/2

Switch(config-if)# cpe duplex auto

auto The port automatically detects whether to run in full- or half- duplex mode.

full The port is in full-duplex mode.

half The port is in half-duplex mode.

port port-id (Optional) CPE Ethernet port identifier. The range is 1to 4, depending on CPE

device.
