This section defines packet match criteria supported on SR OS for IPv4, IPv6, and MAC filters. Supported criteria types depend on the hardware platform and filter direction, see your Nokia representative for more information.
General notes:
If multiple unique match criteria are specified in a single filter policy entry, all criteria must be met in order for the packet to be considered a match against that filter policy entry (logical AND).
Any match criteria not explicitly defined is ignored during match.
An ACL filter policy entry with match criteria defined, but no action configured, is considered incomplete and inactive (an entry is not downloaded to the line card). A filter policy must have at least one entry active for the policy to be considered active.
An ACL filter entry with no match conditions defined matches all packets.
Because an ACL filter policy is an ordered list, entries should be configured (numbered) from the most explicit to the least explicit.
