– The auto-negotiation mode should be disabled.
– The duplex mode of optical ports does not support configuration.
4. (Optional) Configure the network cable adaptation mode of the Ethernet port.
Run the mdi command to configure the network cable adaptation mode of the Ethernet
port to match the actual network cable. The network adaptation modes are as follows:
– normal: Specifies the adaptation mode of the network cable as straight-through
cable. In this case, the network cable connecting to the Ethernet port must be a
straight-through cable.
– across: Specifies the adaptation mode of the network cable as crossover cable. In
this case, the network cable connecting to the Ethernet port must be a crossover
cable.
– auto: Specifies the adaptation mode of the network cable as auto-sensing. The
network cable can be a straight-through cable or crossover cable.
Pay attention to the following points:
– The Ethernet optical port does not support the network cable adaptation mode.
– If the Ethernet electrical port works in forced mode (auto-negotiation mode
disabled), the network cable type of the port cannot be configured to auto.
l Configure flow control on the Ethernet port.
Run the flow-control command to enable flow control on the Ethernet port. When the flow
of an Ethernet port is heavy, run this command to control the flow to prevent network
congestion, which may cause the loss of data packets. Flow control should be supported
on both the local and peer devices. Pay attention to the following points:
– If the peer device does not support flow control, generally, enable flow control on the
local device.
– If the peer device supports flow control, generally, disable flow control on the local
device.
By default, flow control is disabled.
l Mirror the Ethernet port.
Run the mirror port command to mirror the Ethernet port. When the system is faulty, copy
the traffic of a certain port to the other port and output the traffic for traffic observation,
network fault diagnosis, and data analysis.

Example
Ethernet port 0/19/0 is an electrical port. The attribute is as follows: The port rate is 1000 Mbit/
s in duplex mode, with supporting flow control, not supporting auto-negotiation function. Do as
follows:
huawei(config)#interface 0/19
huawei(config-if-0/19)#auto-neg 0 disable
huawei(config-if-0/19)#speed 0 1000
huawei(config-if-0/19)#duplex 0 full
huawei(config-if-0/19)#flow-control 0
