This table configures thresholds that can be monitored for - all MUs and/or - all Portals and/or - all WLANs and/or - for the entire switch When a given threshold is crossed, it generates the appropriate corresponding notification, (ccSumStats_: _MU, _Portal, _WLAN, or _Switch). Some thresholds result in notifications when exceeded, and some when the current value sinks below the threshold. This is indicated by the wording of the entry in the entry's _Descr value. In all cases, the summary stat being monitored is the Short value, never the Long value. Note that for thresholds of type thresholdsAvgMuSignal & thresholdsAvgMuNoise, the values being 'watched' are actually negative. In these cases the threshold is specified as a Unsigned32. For example, if you wish to trap on Signal being worse than -75dBm, enter '70'. This works since a user would never want to trap on a threshold of Sinal worse than +10dBm. (SNR is not an issue, since that is a positive value). Any values reported as var-binds in the resultant trap(s) are likewise reported as positive values.
