There is no "average" latency of SNMP. You'll get different latencies depending on the device vendor, how busy the device is, the individual MIB or OID in question, and the underlying network latency. You can improve response time somewhat by using BULK operations, if your devices support SNMPv2c. But if you're looking to grab a large MIB every several milliseconds, you're probably not going to scale very well, and you may well bring your device to its knees. And if any kind of WAN is involved, your network latency alone may take up a good fraction of a second; an intercontinental WAN can easily have more than 100ms of round-trip latency, and if a satellite link is involved, you can go a lot higher. RMON includes a whole lot of features that are intended to reduce the need for management stations to do a lot of polling. You may want to use them. - Morty ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Net-snmp-users mailing list [email protected] Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users
