CLEAR-Flow
• CLEAR-Flow is a statistical measurement capability in
ExtremeXOS® that:
• Collects data from ACL matches (in the form of counters)
• Uses a switch-based language to evaluate these counters
• Can modify switch behavior based on these evaluations
There are five CLEAR-Flow expressions:
Count Rules: Measure the count of a variable
•
Delta Rules: Measure the change in the count of a variable in a
specific period of time
•
Ratio Rules: Measure the ratio between two variables
•
Delta-Ratio Rules : Measure the change in the ratio between two
variables
•
Rule-True-Count Rules: Measures the number of times a CLEAR-Flow
rule has been true (fired)
