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
OL-10102-01
cpe duplex {{auto | full | half} [port port-id]}
no cpe duplex {{auto | full | half} [port port-id]}
The port automatically detects whether to run in full- or half- duplex mode.
The port is in full-duplex mode.
The port is in half-duplex mode.
(Optional) CPE Ethernet port identifier. The range is 1to 4, depending on CPE
device.
