On Huawei switches, which of the following planes provides network information and forwarding entries that are mandatory for data plane forwarding?
Comprehensive and Detailed in-depth Step-by-Step
To understand this question, let's first review the functional planes in network devices, particularly Huawei switches:
Control Plane:
The control plane is responsible for generating and maintaining routing tables and forwarding entries.
It uses protocols like OSPF, BGP, and RIP to exchange routing information with other network devices. Once the routing information is processed, it installs forwarding entries into the forwarding plane for actual packet forwarding.
On Huawei switches, the control plane is mandatory for building and updating the forwarding table. Without it, the data plane cannot forward traffic correctly.
Forwarding Plane (or Data Plane):
This plane handles the actual forwarding of packets based on the forwarding table created by the control plane.
The forwarding plane operates at high speed to ensure that traffic flows efficiently.
Monitoring Plane:
This plane is responsible for network management and monitoring. It gathers statistics and provides tools for troubleshooting and visibility.
In this case, the control plane provides the routing information and forwarding entries required for the data plane to perform packet forwarding. Therefore, the correct answer is B. Control plane.
