Storm-Constrain - H3C S5120-SI Series Command Reference Manual

Use the undo speed command to restore the default.
The default value of the command varies with your device models.
If you repeatedly use the speed command and the speed auto command to configure the rate of an
interface, only the latest configuration takes effect. For example, if you configure speed 100 after
configuring speed auto 100 1000 on an interface, the rate is 100 Mbps by force, with no negotiation
performed between the interface and the peer end; if you configure speed auto 100 1000 after
configuring speed 100 on the interface, the rate through negotiation can be either 100 Mbps or 1000
Mbps only.
Note that:
If the auto negotiation rate range specified on the local port and that on the peer do not overlap,
for example, 10 Mbps and 100 Mbps are specified on one end while 1000 Mbps is specified on the
other, the auto negotiation of interface rate will fail.
If the auto negotiation rate range specified on the local port and that on the peer overlap, for
example, 10 Mbps and 100 Mbps are specified on one end while 100 Mbps and 1000 Mbps are
specified on the other, the result of the interface rate auto negotiation is the overlapped part, that
is, 100 Mbps in the example.
If the auto negotiation rate range specified on the local port and that on the peer are the same, for
example, 100 Mbps and 1000 Mbps are specified on both ends, the result of the interface rate
auto negotiation is the larger value, that is, 1000 Mbps in the example.
This function is available for auto-negotiation-capable Gigabit Layer-2 Ethernet electrical ports
only..
If you repeatedly use the speed and the speed auto commands to configure the transmission rate
on an port, only the latest configuration takes effect.
Examples
# Set the auto-negotiation rate of interface GigabitEthernet 1/0/1 to 10 Mbps or 1000 Mbps.
