The Class object helps in segregating clients into classes. These clients are treated differently depending on the class they are in.
To create a Class:
A conditional expression is defined to segregate clients into different classes. This separation can be achieved with a conditional statement or with a match statement within the class declaration. Specify the conditional expression you want to define in the field.
To group clients into different classes based on conditional expression, you can specify a match expression within a class statement in the following manner:
match if substring (option dhcp-client-identifier, 1, 3) = "RAS";
A spawning class is used to automatically create lease-limited subclasses based on the client parameters. Select an option from the drop-down list.
The option value sent by the client is checked against the dynamically created subclasses for the specified class. If a match is found, the client is classified under that subclass and treated accordingly. If no match is found, the server creates a new subclass and logs the information in the lease file, and the client is classified in this new subclass. After classification, it is processed according to the rule set for the class.
Specify the comments in the Comments field. This is optional.
These settings are used to define configuration settings for a Class.
