▄  Thresholding Configuration Guide, StarOS Release 16 

Forwarded packet thresholds generate alerts or alarms based on the total number of packets that were forwarded to 
active system CPU(s) during the specified polling interval. Packets are forwarded to active system CPUs when the 
NPUs do not have adequate information to properly route them. 

  Ping and/or traceroute packets are intentionally forwarded to system CPUs for processing. These 

packet types are included in the packet count for this threshold. 

Alerts or alarms are triggered for forwarded packets based on the following rules: 



 

Enter condition: Actual number of forwarded packets > or = High Threshold 



 

Clear condition: Actual number of forwarded packets < Low Threshold 

If a trigger condition occurs within the polling interval, the alert or alarm will not be generated until the end of the 
polling interval. 

Use the following example to configure the forwarded packet thresholds: 

configure 

   threshold packets-forwarded-to-cpu <high_thresh> [ clear <low_thresh> ] 

   threshold poll packets-forwarded-to-cpu interval <time> 

   threshold monitoring packets-forwarded-to-cpu
