Abstract

Embodiments described herein provide techniques for atomically updating a ternary content addressable memory (TCAM)-based access control list (ACL). According to one embodiment, a current version bit of the ACL is determined. The current version bit indicates that a rule in the ACL is active is the version flag in the rule matches the current version bit. Through these techniques, a first set of rules can be modified to create a second set of rules (e.g., by insertions, deletions, and replacements, etc.).
