The control plane consists of applications and protocols between network devices, including Border Gateway Protocol (BGP) and Interior Gateway Protocols (IGPs) such as Enhanced Interior Gateway Routing Protocol (EIGRP) and Open Shortest Path First (OSPF).

Control plane: The control plane of a network device processes the traffic that is important to maintaining the functions of the network infrastructure.

This plane consists of applications and protocols such as Secure Shell (SSH) and Simple Network Management Protocol (SNMP).

Management plane: The management plane is the flow path that traffic uses when it is sent to a Cisco NX-OS device.

Each provides functions that need to be protected. The three functional planes of a network are the management plane, control plane, and data plane. It provides an overview of each security feature included in Cisco NX-OS and includes references to related documentation. The document is organized according to the three planes into which functions of a network device can be categorized.

Use Authentication, Authorization, and Accounting

Then the client will be put into VLAN 1, which is designated as the Guest VLAN.Monitor Cisco Security Advisories and Responses However, if the client is rejected or the RADIUS server is unreachable: When a client completes the authentication, meaning the RADIUS server is reachable and it received 'Access-Accept' as a result of the authorization process. In an SSID using MAC authentication with a VLAN tagging of 10, using RADIUS Guest VLAN with a Guest VLAN of 1. Once selected, the option to fill the Guest VLAN information will be displayed where the VLAN ID can be input: In order to configure this feature, a new option can be found on Wireless > Access Control, when MAC-based access control (no encryption) is selected, you will see the following option, where it can be selected ' Use Guest VLAN/Don't use Guest VLAN': This feature is introduced from 27.2 and on This configuration can be used with VLAN tagging or without it, meaning the authorized clients can be put in the designated VLAN by VLAN tagging option, or can use the untagged VLAN the AP is using (default behavior without using vlan tagging). A configuration where authenticated devices are desired to be on a designated VLAN and everything else, using the same SSID, would be placed in a Guest VLAN. This feature allows the use of a guest vlan for customers that do not complete authentication or when the RADIUS server is unreachable. MAB authentication fallback to Guest VLAN
