With Time Ranges, you specify the fixed date and time ranges or recurring or cyclic time ranges specified
by one or more days of the week that the rule takes effect. Operators can then assign the specified time
range to one or more rules in a template.
With Wildcard Mask, or the subnet mask inversion function, you identify an IP subnet by specifying an
IP address and a subnet mask. ACL Management automatically inverts the subnet mask into a wildcard
mask when applying the configuration to devices.
Managing services using the ACL assistant
In ACL Management, a service is a mnemonic for the TCP or UDP port configuration of a service, an
application, or group of services or applications. Once you create a service in ACL Management using
the ACL Assistant, you can refer to this service when configuring the port information in a template rule.
Each service is comprised of a service name and a set of port numbers. For example, you can define a
service called Telnet and specify port 23 as the port for the Telnet service. Or, you can create a service
group that specifies one or more ports for one or more services or applications. For example, your
organization has a network management application called "WatchIT" and the application uses ports in
the range of 1001 to 1010. You can create a service called "WatchIT" and define the ports used by this
application in the service. Once you have created the "WatchIT" service, you can specify its name in the
Variable Port fields of an advanced ACL template rule configuration.
