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 that
both ends support by default. You can narrow down the speed option list for negotiation.

As shown in
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 Ethernet 1/0/4, the port providing access
to the Internet for the servers.
To avoid congestion on Ethernet 1/0/4, set 100 Mbps as the only option available for speed
negotiation on port Ethernet 1/0/1, Ethernet 1/0/2, and Ethernet 1/0/3. As a result, the transmission
rate on each port connected to a server is limited to 100 Mbps.
To set speed options for auto negotiation on an Ethernet interface:
Step
1. Enter system view.
2. Enter Ethernet interface view.
3. Set speed options for auto negotiation.

By default, the switch allows jumbo frames
within 10000 bytes to pass through Ethernet
interfaces.
If you set the value argument multiple times, the
latest configuration takes effect.
