nwAppnSysIsrLowerThresh
Module: CTRON-APPN-MIB
OID (symbolic): CTRON-APPN-MIB::nwAppnSysIsrLowerThresh
OID (numeric): 1.3.6.1.4.1.52.4.2.2.2.3.5.2.1.1.2.20
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Specifes the number of ISR sessions at which congestion status will revert to uncongested. This must be a non-negative number. nwAppnSysIsrLowerThresh must be less than nwAppnSysIsrUpperThresh to prevent thrashing.
What is nwAppnSysIsrLowerThresh?
This read-write integer specifies the ISR session count at which congestion status reverts to uncongested, and it must stay below nwAppnSysIsrUpperThresh to avoid thrashing between states. The gap between the two thresholds acts as hysteresis, preventing the router from rapidly flapping its congestion signal as session count hovers near the limit. An admin tuning for stability might widen the gap between this lower threshold and the upper one if congestion status was flapping too often.
