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
1.
x.
Take the min of x and 5 Mbps.
2.
The value of the subscriber-rate scheduler profile is less than 1 Mbps, specifically
Example 1
500,000.
The max of 500K and1 Mbps is 1 Mbps
The min of 1Mbps and 5 Mbps is 1 Mbps
