I want to add new ACL rules to a Cisco router. I have no previous experience with cisco.
Many resources about Cisco acls have instructions on applying the acl rules to an interface. But I need to know which ACL rule is already active in an interface, so that I can add new rules to it.
show interfaces command does not display the ACLs, which command is used to get the ACLs on an interface?
Edit: this page states
show ip access-list interface tunnel 0 command for displaying ACLs on an interface, but it is usable only on IOS 12.4 and newer. What are my options in an IOS 11.1 router?
Solution: The issue is solved, but I don't know how :) I was told that somebody else™ fixed the issue.
