Which two protocols can be affected by MPP? (Choose two)
Correct Answer: CE
Examples of protocols processed in the management plane are Simple Network Management Protocol
(SNMP), Telnet, HTTP, Secure HTTP (HTTPS), and SSH. These management protocols are used for
monitoring and for CLI access. Restricting access to devices to internal sources (trusted networks) is critical.
The Management Plane Protection (MPP) feature in Cisco IOS software provides the capability to restrict the
interfaces on which network management packets are allowed to enter a device. The MPP feature allows a
network operator to designate one or more router interfaces as management interfaces. Device management traffic is permitted to enter a device only through these management interfaces. After MPP is enabled, no interfaces except designated management interfaces will accept network management traffic destined to the device.
Restricting management packets to designated interfaces provides greater control over management of a
device, providing more security for that device. Other benefits include improved performance for data packets on nonmanagement interfaces, support for network scalability, need for fewer access control lists (ACLs) to restrict access to a device, and management packet floods on switching and routing interfaces are prevented from reaching the CPU.
