What is control plane protection?
There are two ways to protect the control plane. The first is to secure each protocol used on this plane, and the second is to police the traffic arriving at it. While the mechanisms used to secure various protocols differ, policing the traffic is done using a feature called Control Plane Policing (CoPP).
What is control plane ACL?
Explaining the default Control Plane ACL- Control-plane traffic is defined as the traffic that is destined to or sourced from the CPU. An access-list applied to the control-plane traffic is called the control-plane ACL.
What is control plane Policing CoPP?
Control Plane Policing (CoPP) is the mechanism that allows us to policy the coming traffic to the Control Plane. Here, CoPP defines traffic classification, queue mapping and queue shaping for control plane packets. This protects Control Plane from malicious network attacks like DoS Attacks.
What is CoPP on switch?
The control plane policing (CoPP) feature increases security on the switch by protecting the RP from unnecessary or DoS traffic and giving priority to important control plane and management traffic. The PFC and DFCs provide hardware support for CoPP. CoPP works with the hardware rate limiters.
What is the difference between CoPP and CPPr?
Although it is similar to Control Plane Policing (CoPP), CPPr has the ability to restrict/police traffic using finer granularity than that used by CoPP. CPPr divides the aggregate control plane into three separate control plane categories, known as subinterfaces: (1) host, (2) transit, and (3) CEF-exception.
What is control plane traffic?
Control plane—Handles all routing protocol control traffic. These protocols, such as the Border Gateway Protocol (BGP) and the Open Shortest Path First (OSPF) Protocol, send control packets between devices. These packets are destined to router addresses and are called control plane packets.
What is control plane and data plane?
The control plane is the part of a network that controls how data is forwarded, while the data plane is the actual forwarding process.
What is CoPP in network?
Control Plane Policing (CoPP): allows you to use MQC (Modular Quality of Service) framework to permit/deny or rate-limit traffic that goes to the route processor. Control Plane Protection (CPPr): this is an extension of CoPP. One of the things it does is separating the route processor into three sub-interfaces: host.
What do CoPP and CPPr have in common?
CPPr is very similar to CoPP and has the ability to filter and police traffic using finer granularity by dividing the aggregate control plane into three separate categories: (1) host, (2) transit, and (3) CEF-exception. Hence, a separate policy-map could be configured for each traffic category.
What is CPPr Cisco?
Overview. Starting with Cisco IOS Software release 12.4(4)T, Control Plane Protection (CPPr) can be used to restrict and/or police control plane traffic destined to the route processor of the Cisco IOS device.
What is control plane and data plane in LTE?
What is control plane and forwarding plane?
Software-Defined Networks Software-defined networking (SDN) separates a router’s control plane from the data (forwarding) plane. The control plane makes routing decisions. The data plane forwards data (packets) through the router. With SDN routing, decisions are made remotely instead of on each individual router.
