Note:
z
Only combo optical 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.
z
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.
z
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 the following configurations, you can limit different types of incoming
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:
