Set a class-map to match the ACL set in the second step4, set a Policy-map match Class-map, and then define a series of policies here, limit the bandwidth bitwise (BIT) for the calculation, burst in bytes (byte) calculation5, apply the POLICY-MAP to the corresponding interfaceMLS QoSIP Access-list Extended

When we want to perform permission rating management on a Cisco router or switch, it is often necessary to assign different levels of users a command that exceeds the default settings, such as show run, which is the most basic troubleshooting command.However, the command cannot be executed when your user level is at 0-14. You can assign permissions to these users using the following command:Privilege EXEC l

Whether it's on a Cisco router or a network device such as a Cisco switch, the standard ACL access control list is always unable to match both the traffic source address and the destination address, nor does it meet the requirements of the "granular" control of the current network world, such as: A service function that allows access to a server, However, pinging
