This document describes the support for user-defined fields (UDF) acl rules in QoS policy feature. This feature is an extension of QoS policy to allow increased flexibility of the match criteria by using user-defined fields which will help customers control traffic based on other parts of the packet header and payload that is not supported by the other key-fields.

User Defined Fields (UDFs) are access-list (ACL) filters that consist of an offset into a packet and a pattern to match at the given offset. It can be used to match non-standard fields in a packet that don’t have existing well-defined filter criteria. An example of a non-standard field is bytes at an arbitrary offset within a UDP payload.

This document describes the support for user-defined fields (UDF) ACL rules in egress mac/IPv4/IPv6 access lists. This feature is an extension of egress ACL to allow increased flexibility of the match criteria by using user-defined fields which will help customers control traffic based on other parts of the packet header and payload that is not supported by the other key-fields.

User Defined Field (UDF) filtering enables offset-based matching. This feature supports the use of UDFs on EOS 7280R3 platforms.
