Usage Information When you use the access-class access-list-name command without specifying the ipv4 or ipv6 attribute, both IPv4 as well as IPv6 rules that are defined in that ACL are applied to the terminal. This method is a generic way of configuring access restrictions. To be able to filter access exclusively using either IPv4 or IPv6 rules, use either the ipv4 or ipv6 attribute along with the access-class access-list-name command. Depending on the attribute that you specify (ipv4 or ipv6), the ACL processes either IPv4 or IPv6 rules, but not both. Using this configuration, you can set up two different types of access classes with each class processing either IPv4 or IPv6 rules separately. However, if you already have configured generic IP ACL on a terminal line, then you cannot further apply IPv4 or IPv6 specific filtering on top of this configuration. Because, both IPv4 and IPv6 access classes are already configured on this terminal line. Before applying either IPv4 or IPv6 filtering, first undo the generic configuration using the no access-class access-list-name command. Similarly, if you have configured either IPv4 or IPv6 specific filtering on a terminal line, you cannot apply generic IP ACLs on top of this configuration. Before applying the generic ACL configuration, first undo the existing configuration using the no access-class access-list-name [ipv4 | ipv6] command. clear counters ip access-group Erase all counters maintained for access lists. Syntax Parameters clear counters ip access-group [access-list-name] access-list-name (OPTIONAL) Enter the name of a configured access-list, up to 140 characters.
