How to Configure CNU Port Attributes on MA5631 & MA5632
Context
Ensure that the attributes of the Ethernet port on the CNU are the same as those of the peer port on the MA5631/MA5632.
Configuration:
1 The procedure for configuring the Ethernet port attributes of a CNU is as follows:
In EoC mode, run the cnu port attribute command to configure the attributes of the
Ethernet port on the CNU. The main parameters are as follows:
– auto-neg: Indicates the auto-negotiation mode of the Ethernet port on the CNU. You can enable or disable the auto-negotiation mode.
– After the auto-negotiation mode is enabled, the Ethernet port automatically
negotiates with the peer port for the rate and working mode of the Ethernet port.
– After the auto-negotiation mode is disabled, the rate and working mode of the
Ethernet port are in forcible mode. In forcible mode, the rate and working mode use
default settings or are configured using the command line interface (CLI).
– speed: Indicates the rate of the Ethernet port on the CNU. After the port rate is set, the
port works at the specified rate. Pay attention to the following points during
configuration:
– Ensure that the rate of the Ethernet port is the same as that of the peer port on the
interconnected device. This prevents communication failure.
– The auto-negotiation mode needs to be disabled.
– duplex: Indicates the duplex mode of the Ethernet port on the CNU. The duplex mode can be half-duplex or full-duplex. Pay attention to the following points during
configuration:
– Ensure that the duplex mode of the Ethernet port is the same as that of the peer port on the interconnected device. This prevents communication failure.
– The auto-negotiation mode needs to be disabled.
– operational-state: Indicates the activation status of the Ethernet port on the CNU.
– flow-control: Indicates the flow control on the Ethernet port on the CNU. When the traffic on the Ethernet port is heavy and needs to be controlled, enable flow control to prevent network congestion and packet loss.

Example
Assume that:
l The port rate is 100 Mbit/s.
l The working mode of the port is full-duplex.
l The port supports flow control.
l The port does not support auto-negotiation mode.
l The activation status of the port is enabled.
To configure the preceding attributes for the Ethernet port on the CNU, do as follows:
huawei(config)#interface eoc 0/1
huawei(config-if-eoc-0/1)#cnu port attribute 0 1 eth 1 auto-neg off
huawei(config-if-eoc-0/1)#cnu port attribute 0 1 eth 1 speed 100
huawei(config-if-eoc-0/1)#cnu port attribute 0 1 eth 1 duplex full
huawei(config-if-eoc-0/1)#cnu port attribute 0 1 eth 1 flow-control on
huawei(config-if-eoc-0/1)#cnu port attribute 0 1 eth 1 operational-state on
