Benefits of Management Plane Protection
Implementing the MPP feature provides the following benefits:
-
Greater access control for managing a device than allowing management protocols on all interfaces.
-
Improved performance for data packets on non-management interfaces.
-
Support for network scalability.
-
Simplifies the task of using per-interface access control lists (ACLs) to restrict management access to the device.
-
Fewer ACLs are needed to restrict access to the device.
-
Prevention of packet floods on switching and routing interfaces from reaching the CPU.
