The NMS is usually configured to poll all of the key devices in the network periodically using SNMP Get requests. These are UDP packets sent to the agent on the wellknown SNMP port 161. The SNMP Get request prompts the remote device to respond with one or more pieces of relevant operating information.
However, because there could be hundreds or thousands of remote devices, it isoften not practical to poll a particular remote device more often than once every few minutes (and in many networks you are lucky if you can poll each device more than a few times per hour). On a schedule like this, a remote device may suffer a serious
problem that goes undetected—it’s possible to crash and reboot in between polls from the NMS. So, on the next poll, the NMS will see everything operating normally and never know that it completely missed a catastrophe.
