configuring speed auto 100 1000 on an interface, the rate is 100 Mbps by force, with no negotiation 

performed between the interface and the peer end; if you configure speed auto 100 1000 after 

configuring speed 100 on the interface, the rate through negotiation can be either 100 Mbps or 1000 

Mbps only. 

Note that: 

z 

When the auto-negotiation rate ranges set on the local and peer ends do not intersect, for example, 

10 and 100 Mbps on one end and 1000 Mbps on the other, the rate negotiation will fail. 

z 

When the auto-negotiation rate ranges set on the local and peer ends intersect, for example, 10 

and 100 Mbps on one end and 100 and 1000 Mbps on the other, the negotiation rate range is the 

intersection, 100 Mbps. 

z 

When the auto-negotiation rate ranges set on the local and peer ends are the same, for example, 

100 and 1000 Mbps, the maximum value of the auto-negotiation rate is 1000 Mbps.  

 

z 

This function is available for auto-negotiation-capable 100 MB or Gigabit Layer-2 Ethernet 

interfaces only. For a Combo port, only the electrical port supports this function. 

z 

If you repeatedly use the speed and the speed auto commands to configure the transmission rate 

on an interface, only the latest configuration takes effect.

packets, and broadcast packets).
