sample a packet.
5. Set the maximum copied
length of a sampled packet.
6. Specify the sFlow collector for
flow sampling.

To do...
1. Enter system view.
2. Enter layer 2 or layer 3
Ethernet interface view.
3. Set the interval for counter
sampling.
4. Specify the sFlow collector for
counter sampling.
