z
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.
z
This function is available for auto-negotiation-capable Gigabit Layer-2 Ethernet electrical ports
only..
z
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.

Default Level
2: System level
Parameters
all : Disables the storm constrain function for all types of packets (that is, multicast packets, and
broadcast packets).
broadcast : Enables/Disables the storm constrain function for broadcast packets.
multicast : Enables/Disables the storm constrain function for multicast packets.
pps : Specifies the storm constrain threshold in terms of number of packets.
kbps : Specifies the storm constrain threshold in terms of number of kilobytes.
ratio : Specifies the storm constrain threshold in terms of percentages of the received packets to the
whole transmission capacity.
max-values : Upper threshold to be set, in pps, kbps, or percentages.
When the threshold is set in pps:
z
For a Gigabit port, the value range is 1 to 1488100.
