3.3.5 Setting the Rate for an Ethernet Interface

Ethernet interfaces on both ends of a link must work at the same rate.
Context
In auto-negotiation mode, interfaces on both ends of a link negotiate their rate. If the negotiated
rate is not the required rate, you can set the auto-negotiation rate range to limit the negotiated
rate. For example, if two interfaces negotiate to work at a rate of 10 Mbit/s, but they are required
to work at a rate of 100 Mbit/s, you can run the auto speed 100 command to set the rate of the
interfaces to 100 Mbit/s.
In non-auto negotiation mode, you must set the rate for interfaces so that devices of the interfaces
can communicate.
Procedure
l
l
Issue 01 (2012-04-20)
The Ethernet interface works in non-auto negotiation mode.
4. Run:
duplex { full | half }
The duplex mode is set for the Ethernet interface.
By default, an Ethernet interface in non-auto negotiation mode works in full duplex
mode.
Setting the rate in auto-negotiation mode
1. Run:
system-view
The system view is displayed.
2. Run:
interface { ethernet | gigabitethernet } interface-number
The Ethernet interface view is displayed.
3. Run:
auto speed { 10 | 100 | 1000 }
The auto-negotiation rate range is set for the Ethernet interface.
By default, Ethernet interfaces on both ends can negotiate to any rate supported by
them. The rate of an FE interface cannot be set to 1000 Mbit/s.
