The following configuration gathers statistical sampling information from a small percentage of all traffic on a single SONET/SDH interface and collects it in a file named sonet-samples.txt.
Create the filter:
- [edit firewall family inet]
- filter {
-
- input sample-sonet {
-
- then {
- sample;
- accept;
- }
- }
- }
Apply the filter to the SONET/SDH interface:
- [edit interfaces]
- so-0/0/1 {
-
- unit 0 {
-
- family inet {
-
- filter {
- input sample-sonet;
- }
-
- address 10.127.68.254/32 {
- destination 172.16.74.7;
- }
- }
- }
- }
Finally, configure traffic sampling:
- [edit forwarding-options]
- sampling {
-
- input {
-
- family inet {
- rate 100;
- run-length 2;
- }
- }
-
- output {
-
- file {
- filename sonet-samples.txt;
- files 40;
- size 5m;
- }
- }
- }
