Q. I am probing Cisco CallManager with the SNMP Traffic probe. When the poll interval is set to between 30 seconds and one minute, the interface traffic statistics are incorrect resulting in saw-like charts. If I increase the poll interval to two minutes, the traffics statistics are correct.

A. This issue appears to be a bug in the CallManager security agents running on Linux. The same agents running on Windows do not have a problem with 30-second queries.
