3. Troubleshooting Functional Failures in Operation

3.15.2Flow Sample Does Not Reach Collector

If problem still persists even after checking "3.15.1 sFlow Packets Do Not Reach Collector," check the following:

(1) Checking presence/absence of the relay packet

Execute the show interfaces command to check to see if the packet is relayed.

Note: Confirm that the packet is relayed based on the display at underlined part.

(2) Checking settings of collector

Check to see if settings of the collector used are correct.

3.15.3Counter Sample Does Not Reach Collector

If problem still persists even after checking "3.15.1 sFlow Packets Do Not Reach Collector," check the following:

(1) Checking transmission interval of counter sample

Check to see if the transmission interval of the counter sample related to flow statistics is set to 0 in the configuration of this system. If set to 0, the counter sample data is not sent to the collector.
