Huawei’s free mobility solution is based onsecurity group–based policy control. In this architecture, users are dynamically associated with security groups after authentication. These security group identifiers are thencarried in user trafficas metadata when packets traverse the campus network.

When traffic reaches apolicy enforcement device, such as an edge node or border node, the device does not rely on traditional attributes like IP address, MAC address, or port number to make forwarding decisions. Instead, it extracts thesource and destination security group informationembedded in the traffic and matches it against the security policy matrix configured on the controller.

This mechanism enables identity-based and location-independent access control. Even if a user moves to a different access point or changes an IP address, the same security policies continue to apply as long as the user remains in the same security group. This is the core advantage of free mobility in Huawei campus networks.

Port numbers, MAC addresses, and IP addresses are traditional Layer 2 and Layer 3 identifiers, but they do not provide sufficient context for identity-based policy enforcement. According to HCIP Datacom Campus Network documentation, security group information is the key attribute used for policy lookup and enforcement in free mobility solutions. Therefore, option A is correct.

In IPsec, bothAuthentication Header (AH)andEncapsulating Security Payload (ESP)are implemented as IP protocols and are identified by specificIP protocol numbersin the IP header. These protocol numbers allow receiving devices to determine how the packet payload should be processed.

The protocol number assigned toAH is 51. AH provides data origin authentication, data integrity, and anti-replay protection but does not offer encryption. When an IP packet contains AH, the protocol field in the IP header is set to 51 so that the receiver can correctly process the AH header.

The protocol number assigned toESP is 50. ESP provides data confidentiality through encryption and can also provide integrity and authentication. Packets protected by ESP use protocol number 50 in the IP header.

The other options are incorrect because protocol number6represents TCP and17represents UDP, which are transport-layer protocols rather than IPsec protocols. Protocol number57is unrelated to IPsec.

According to HCIP Datacom Campus Network documentation and standard IP protocol assignments, the correct protocol numbers are AH = 51 and ESP = 50, making option B the correct answer.

To deploy802.1X authenticationon Huawei campus switches and use aRADIUS serverfor user authentication and authorization, several core configuration components are mandatory. All four options listed are required for a complete and functional deployment.

Anauthentication domainis mandatory because it defines where user authentication requests are processed and which AAA schemes are used. Without a domain, the switch cannot determine how to handle authentication requests, makingoption A mandatory.

Anauthentication profileis also required. This profile binds authentication methods (such as 802.1X), authentication domains, and access policies together. Interfaces reference the authentication profile to determine how users are authenticated, sooption B is mandatory.

An802.1X access profiledefines detailed 802.1X parameters, such as authentication mode, reauthentication behavior, and client handling. This profile is bound to interfaces to enable 802.1X authentication on specific ports, makingoption C mandatory.

Finally, anAAA schemeis essential because it defines the authentication, authorization, and accounting methods used by the device, including RADIUS server configuration. Without an AAA scheme, the device cannot communicate with the RADIUS server or obtain user authorization information. Therefore,option D is mandatory.

According to HCIP Datacom Campus Network documentation, all four configuration steps are required to successfully enable 802.1X authentication with RADIUS-based access control.
