Abstract: Technologies for updating an access control list (ACL) table while minimizing disruption includes a network device. The network device receives a request to store a rule in the ACL. The rule is associated with a precedence group. A precedence group is indicative of a placement priority of a given rule in the ACL. The network device determines, as a function of the precedence group, a placement for the requested rule in the ACL. The network device stores the rule according to the determined placement in the ACL.

Abstract: There is disclosed in one example a network switching apparatus, including: a plurality ingress port; a plurality of egress ports; a ternary content addressable memory (TCAM) comprising a plurality of chunks, wherein the chunks can be atomically enabled or disabled; a switching circuit to switch traffic from the ingress port to a selected egress port according to an access control list (ACL) of the TCAM; and one or more non-transitory mediums having stored thereon instructions to atomically add or update two or more target rules, including: add the two or more target rules to one or more target-rule chunks; and atomically enable the target-rule chunks.
