An arbitrary (system assigned) index for each ACL name. The
index is unique for each ACL name in the device, but is further
qualified by the address family.
For example, consider the following configuration:
ipv4 access-list ACL1
10 permit ipv4 any any
!
ipv6 access-list ACL1
10 permit ipv6 any any
In this case the caAclIndex value for both ACLs will be the
same.
