Dynamic Calculation Logic for Different Variable Types

Golden Baseline for string/number/table-type variables can be dynamically calculated.

String-Type Variable:

The Golden Baseline for the following two string-type variables can be dynamically calculated.

• Equals any of – at least requires data at 10 different time points for calculation, and the count of unique data must be no greater than 3.
• Equals – at least requires data at 4 different time points for calculation, and the first three values must be the same. See the following table for an example of the IOS version.

	1st Time	2nd Time	3rd Time	4th Time	5th Time	6th Time	7th Time	8th Time
Data (IOS Version)	12.1	12.1	12.1	12.1	12.2	12.2	12.2	12.2
Golden Baseline	Calculating	Calculating	Calculating	Equals 12.1	Equals 12.1	Equals 12.1	Equals 12.1	Equals 12.2
Alert	N/A	N/A	N/A	No Alerts	Alert Detected	Alert Detected	Alert Detected	No Alerts

Number-Type Variable:

The Golden Baseline for the following number-type variables can be dynamically calculated:

Table-Type Variable:

According to the predefined compared columns, the system generates hash values in parsers and converts them into single-value strings for comparison and analysis. The analysis logic is the same as that for string-type variables.

Take the following table as an example. If the “BGP Neighbor”, “Version,” and “AS Number” columns are predefined as compared columns, then only the corresponding hash values for these three columns will be generated for comparison.
