Which command is used to determine if an IP access list is enabled on a particular interface?

The command used to determine if an IP access list is enabled on a particular interface is "show ip interface." This command provides detailed information about the current status of all interfaces, including any access lists applied to them. When executed, it displays various parameters, such as whether an interface is up or down, the assigned IP address, and pertinent ACL (Access Control List) information.

For instance, if an access list is applied to an interface, this command will indicate that along with the specific access list's name. This makes it a comprehensive command for network administrators to monitor and troubleshoot interface settings and functionalities, particularly regarding security policies enforced by access lists.

Other commands, such as showing access lists or interface status, might provide some relevant information, but they do not specifically clarify whether an access list is in effect on a particular interface like "show ip interface" does. Consequently, using "show ip interface" is the most effective way to ascertain the presence and status of access lists associated with network interfaces.
