Information About IPv6 ACL—Template ACL
IPv6 Template ACL
When user profiles are configured using vendor-specific attribute (VSA) Cisco AV-pairs, similar per-user IPv6 ACLs may be replaced by a single template ACL. That is, one ACL represents many similar ACLs. By using IPv6 template ACLs, you can increase the total number of per-user ACLs while minimizing the memory and Ternary Content Addressable Memory (TCAM) resources needed to support the ACLs.
The IPv6 Template ACL feature can create templates using the following ACL fields:
IPv6 source and destination addresses
TCP and UDP, including all associated ports (0 through 65535)
ICMP neighbor discovery advertisements and solicitations
IPv6 DSCP with specified DSCP values
ACL names are dynamically generated by this feature; for example:
6Temp_#152875854573--Example of a dynamically generated template name for a template ACL parent
Virtual-Access2.32135#152875854573--Example of a child ACL or an ACL that has not yet been made part of a template.
