Optional
z
By default, the port speed is
determined through
auto-negotiation.
z
Use the
1000
keyword for Gigabit
Ethernet ports only.
z
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.
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.
Limiting Traffic on individual Ports
By performing the following configurations, you can limit the incoming 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.
