Objects which can be monitored. * **phy(0)** monitor checks periodically the link status of the ethernet interfaces defined by `cfgNlmMonInterfaces`. If at least one interface in the list specified is up the monitor is considered up. * **icmp(1)** monitor pings periodically the destination defined by `cfgNlmMonDestination`. If the destination does reply to the ECHO request within the `cfgNlmMonInterval` the monitor is considered up. * **wlan(2)** monitor listens to link status events of the wireless interface defined by `cfgNlmMonInterfaces`. The wlan monitor consists of 3 components: **Long Handoff Detector** - Triggers when after disassociation no authorization event is detected within the configured time in `cfgNlmMonInterval`. **Scan Loop Detector** - Triggers immediately on trap 415. This happens if there is no AP or only a single AP which stays below/above the Handoff thresholds. This trap is only generated when `cfgWlanHoProfile` is set to 2 or higher. **Handoff Loop Detector** - Triggers if there have been `cfgNlmMonCount` number of Handoff events within `cfgNlmMonCount` * (`cfgNlmMonInterval` + `cfgNlmMonScanLoopInterval`). The wlan monitor recovers: **Long Handoff Detector** - Immediately after the next successful authorization. **Scan Loop Detector** - After the time of the last 415 trap event + the configured `cfgNlmMonScanLoopInterval`. When down, this is checked regularly in `cfgNlmMonScanLoopInterval` intervals. **Handoff Loop Detector** - When there are less than `cfgNlmMonCount` Handoff events within the time-window `cfgNlmMonCount` * (`cfgNlmMonInterval` + `cfgNlmMonScanLoopInterval`). When down, this is checked regularly in `cfgNlmMonScanLoopInterval` intervals. **Note**: WLAN monitor is supported for 802.11n products only. Applies to AP and STA.
