4.3.2.1.2.2 Defining the auto-negotiation mode
The auto-negotiation feature enables the system to automatically negotiate the
port speed and the duplex (half or full) status with the link partner. If you disable
auto-negotiation, you are required to manually configure the port speed and
duplex status.
Run the following command to enable the auto-negotiation mode:
npu(config-if)# auto-negotiate
Enter the following command if you want to disable the auto-negotiation mode:
npu(config-if)# no auto-negotiate
After you disable auto-negotiation, you can manually configure the port speed and
duplex status. For details, refer to Section 4.3.2.1.2.3 and Section 4.3.2.1.2.4
