Configure the available
auto-negotiation speed(s)
for the port
Note:
Only ports on the front panel of the device support the auto-negotiation speed
configuration feature. And ports on the extended interface card do not support this
feature currently.
After you configure auto-negotiation speed(s) for a port, if you execute the undo
speed command or the speed auto command, the auto-negotiation speed setting
of the port restores to the default setting.
The effect of executing speed auto 10 100 1000 equals to that of executing speed
auto, that is, the port is configured to support all the auto-negotiation speeds: 10
Mbps, 100 Mbps, and 1000 Mbps.

1.1.3 Limiting Traffic on individual Ports

By performing
broadcast/multicast/unknown unicast traffic on individual ports. When a type of
incoming traffic exceeds the threshold you set, the system drops the packets exceeding
the traffic limit to reduce the traffic ratio of this type to the reasonable range, so as to
keep normal network service.
Follow these steps to limit traffic on port:
