Parameters
length
: Specifies the maximum number of bytes that can be copied, in the range of 18 to 512. As a
best practice, use the default.
Examples
# Set the maximum number of bytes that can be copied to 60 on GigabitEthernet 1/0/1.

sflow sampling-mode
Use
sflow sampling-mode
to specify a flow sampling mode.
Use
undo
sflow sampling-mode
to restore the default.

Parameters
determine
: Specifies the fixed sampling mode. This keyword is not supported in the current software
version. This keyword is reserved for future support. For example, if the flow sampling interval is set
to 4000 (by using the
sflow sampling-rate
command), the switch samples packets as follows:
•
The device randomly samples a packet, like the tenth packet, from the first 4000 packets.
•
The next time the switch samples the 4010th packet, and so on.
random
: Specifies the random sampling mode. For example, if the packet sampling interval is set to
4000, the switch samples packets randomly as follows:
•
The switch might sample one packet from the first 4000 packets.
