Object

column r/w Enumeration

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.
