Usage Guidelines

By default, the transmission rate of an Ethernet interface is the maximum rate.

Run the undo negotiation auto command before you adjust the transmission rate of an interface.

Only MEth, GE, and WAN interfaces support this command. For the GE interface, this command cannot be be configured after it is equipped with a copper module.

Example

# Set the transmission rate of Ethernet interface GigabitEthernet 0/0/1 to 100 Mbps.

<sysname> system-view
[sysname] interface GigabitEthernet 0/0/1
[sysname-GigabitEthernet0/0/1] undo negotiation auto
[sysname-GigabitEthernet0/0/1] speed 100
