Real Test Case General

Test Information

This is a real test case using the server to monitor some SNMP devices over a slow network.
In a typical network environment there are equipments from many vendors and consequently different implementations of SNMP protocol which may interfere in performance, plus not all devices supports SNMPv2 which is known to be a faster implementation than SNMPv1.
