Setting speed options for auto negotiation on an Ethernet
interface
Speed auto negotiation enables an Ethernet interface to negotiate with its peer for the highest speed
supported by both ends by default. You can narrow down the speed option list for negotiation.
Figure 1 Speed auto negotiation application scenario
As shown in Figure 1 , all ports on Switch A are operating in speed auto negotiation mode, with the
highest speed of 1000 Mbps. If the transmission rate of each server in the server cluster is 1000 Mbps,
their total transmission rate will exceed the capability of port GigabitEthernet 1/4, the port providing
access to the Internet for the servers.
