Limiting Traffic On Individual Ports - H3C S5100-SI Operation Manual

If you expect that 10 Mbps and 1000 Mbps are the available auto-negotiation speeds of the port,
you just need to configure speed auto 10 1000.
Follow these steps to configure auto-negotiation speeds for a port:
To do...
Enter system view
Enter Ethernet interface
view
Configure the available
auto-negotiation speed(s)
for the port
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.

Limiting Traffic on individual Ports

By performing the following configurations, you can limit the incoming broadcast 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:
To do...
Enter system view
Limit broadcast traffic received
on each port
Enter Ethernet port view
Limit broadcast traffic received
on the current port
Use the command...
system-view
interface interface-type
interface-number
speed auto [ 10 | 100 |
1000 ]*
Use the command...
system-view
broadcast-suppression { ratio
| pps max-pps }
interface interface-type
interface-number
broadcast-suppression { ratio
| pps max-pps }
1-3
