Conﬁguring Network Monitoring Requests

Table 4-2 recommends monitoring requests for each node. With these requests, you would see events when a LAN card fails, and again when it came back up, and you would see an event each hour as long as the LAN card was down. You may elect to change the polling interval or not to conﬁgure a reminder at all.
