What is the functionality of the "crumbsperclasscount" variable?
With this system variable, we are controlling granularity of the “traffic history” command, which records classification history per host, or per class.
It can be configured using the following command; -
sys set crumbsperclasscount integer
The "Traffic history" command is designed for troubleshooting and identifying where a miss-classified flow may have been handled in the class tree by displaying what passed through a given class or specifically which classes a given host may have matched depending on the parameter supplied, with a brief historic record of the source/destination hosts/ports, and the application or protocol name (if available) the shaper was able to identify, grouped by class.
The “crumbs” integer specified determines the level of granularity available in this command in terms of tree depth (by default, this is ten classes deep), and by entering 0 we can disable the functionality all-together which is very useful in complicated, or high bandwidth scenarios.
Examples of the traffic history command and output:
traffic history recent /inbound/default
-----( /Inbound/Default )-----
traffic history find 188.8.131.52
-----( /Outbound/MSSQL )-----
