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 dened in that ACL are applied to the terminal. This
method is a generic way of conguring access restrictions.
To be able to lter 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 conguration,
you can set up two dierent types of access classes with each class processing either IPv4 or IPv6 rules
separately.
However, if you already have congured generic IP ACL on a terminal line, then you cannot further apply
IPv4 or IPv6 specic ltering on top of this conguration. Because, both IPv4 and IPv6 access classes are
already congured on this terminal line. Before applying either IPv4 or IPv6 ltering, rst undo the generic
conguration using the no access-class access-list-name command.
Similarly, if you have congured either IPv4 or IPv6 specic ltering on a terminal line, you cannot apply
generic IP ACLs on top of this conguration. Before applying the generic ACL conguration, rst undo the
existing conguration using the no access-class access-list-name [ipv4 | ipv6]
command.
