SNMP

That depends on the MIB and the polling frequency.

For a simple GET request of only a few MIB variables, it takes only 100-200 _bytes_ (not K). However in many setups the host inquires complete MIB's which can run into 50-100 K everytime. Not very cleverly tuned ;-)

The most problematic tuning area however is polling frequency. If your network management is mostly based on dumb agents and quality is timecritical, then a poll every 5 minutes or less is sometimes needed. Which can be 12 times 100 K every hour towards maybe hundreds of agents in one LAN. Much capacity can be saved by tuning but also by switching to more intelligent agents. Which can rely on infrequent polling (e.g. every hour) for statistical data, and will themselves send a TRAP signal to the host when there is something urgent. Take care however: TRAPs are only really safe in a LAN and not a WAN, because they are UDP based (not TCP). So relying on them might require extra SNMP hosts, or a tool which deviates frompure SNMP by allowing guaranteed trap delivery...

Erik,

Thanks for your quick response.

Would you recommend a site to get more info about my question? I want to get more info about this.

Thanks.
