Example: Sampling a Single SDH Interface
The following configuration gathers statistical sampling information from a small percentage of all traffic on a single SDH interface and collects it in a file named sdh-samples.txt.
Create the filter:
[edit firewall family inet]
filter {
sample-sdh {
then {
sample;
accept;
}
}
}
Apply the filter to the SDH interface:
[edit interfaces]
so-0/0/1 {
unit 0 {
family inet {
filter {
input sample-sdh;
}
address 10.127.68.254/32 {
destination 10.127.74.7;
}
}
}
}
Finally, configure traffic sampling:
[edit forwarding-options]
sampling {
input {
rate 100;
run-length 2;
}
family inet {
output {
file {
filename sdh-samples.txt;
files 40;
size 5m;
}
}
}
