What is the Cisco control plane?
The control plane is where a Cisco switch or router learns about its environment, using various protocols to talk to neighboring devices. The protocols operating on the control plane of a router are different from those of a switch.
What is control plane protection?
The Control Plane Protection feature is an extension of the policing functionality provided by the existing Control-Plane Policing feature. The Control-Plane Policing feature allows Quality of Service (QoS) policing of aggregate control-plane traffic destined to the route processor.
What is CoPP on switch?
The CoPP feature protects the control plane of Cisco IOS Software-based routers and switches against many attacks, including reconnaissance and denial-of-service (DoS) attacks. In this manner, the control plane can maintain packet forwarding and protocol state despite an attack or heavy load on the router or switch.
What is the difference between control plane and management plane?
Control plane — all the functions and processes that determine which path to use (such as LDP, Routing protocols, etc.) Management plane — all the functions you use to control and monitor devices.
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 the 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 Cisco BFD?
BFD is a detection protocol designed to provide fast forwarding path failure detection times for all media types, encapsulations, topologies, and routing protocols. In addition to fast forwarding path failure detection, BFD provides a consistent failure detection method for network administrators.
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.
How do you control a plane?
How does a Pilot Control the Plane?
- The ailerons raise and lower the wings. The pilot controls the roll of the plane by raising one aileron or the other with a control wheel.
- The rudder works to control the yaw of the plane.
- The elevators which are on the tail section are used to control the pitch of the plane.
Why do we separate the control plane and the data plane?
Control plane is responsible for populating the routing table, drawing network topology, forwarding table and hence enabling the data plane functions. Means here the router makes its decision. In a single line it can be said that it is responsible for How packets should be forwarded.
What is 5g user plane and control plane?
The control plane carries the signaling traffic, the user plane the user data (which is the content of communications), and the management plane the administrative traffic. The administrative traffic contains configuration and control commands for RAN and core functions.
Is ARP a control plane?
In distributed architecture platforms, routing protocols, and most other protocols, always run on the core CPU in the RPs or Supervisor engines, but there are other control plane protocols such as ARP, BFD, and ICMP that in some distributed architecture platforms have now been offloaded to the line card CPU.
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.
