Methods and systems have been provided for removing dead Access Control Entries (ACEs) in an Access Control List (ACL). In one embodiment, the dead ACEs can be detected for an egress as well as an ingress ACL. The ACEs that have a hit count above a user-specified hit count are checked for their validity. The validity of the ACE is checked, using the information based on a Forwarding Information Base (FIB). If an ACE is found to be invalid, it is considered dead. The dead ACEs are referred as candidates for removal from the ACL. If the ACE is found to be a candidate for removal, a system administrator can either warn the network administrator about the candidate for removal or delete the ACE from the ACL after a pre-defined time limit.
