Specifying a Range in Expressions

You can use the min and max operators to specify the allowable range of an expression
result.
For example, to specify a shaping rate at a minimum of 1 Mbps and a maximum of 5
Mbps, use the following expression:
host1(config)#scheduler-profile subscriber-rate
host1(config-scheduler-profile)#shaping-rate (( subscriber-rate max 1000000 ) min
5000000 )
Operations Using This Expression
Take the max of the subscriber-rate scheduler profile, or 1 Mbps, and name it x.
1.
Take the min of x and 5 Mbps.
2.
The value of the subscriber-rate scheduler profile is less than 1 Mbps, specifically 500,000.
The max of 500K and1 Mbps is 1 Mbps
The min of 1Mbps and 5 Mbps is 1 Mbps
Result—Made the subscriber-rate a minimum of 1 Mbps.
The value of the subscriber-rate scheduler profile is greater than 5 Mbps, specifically
6 Mbps.
The max of 6 Mbps and 1 Mbps is 6 Mbps
The min of 6 Mbps and 5 Mbps is 5 Mbps
Result—Made the subscriber-rate a maximum of 5 Mbps.
The value of the subscriber-rate scheduler profile is within the range of 1–5 Mbps,
specifically 3 Mbps.
The max of 3 Mbps and 1 Mbps is 3 Mbps
The min of 3 Mbps and 5 Mbps is 3 Mbps
Result—Maintained the subscriber-rate within the range of 1–5 Mbps.
