2OverviewIEEE 802.1x is an IEEE standard for port-based network access control. It is part of the IEEE
802 group of networking protocols. With port-based network access control, the
authentication access equipment in the local area network (LAN) performs identity
authentication and access control on users or devices connected to its ports. Only the users or
devices that can be authenticated are allowed to access the LAN through the ports. Access
Control based on 802.1x prevents unauthorized users or devices from accessing the network,
which ensures transport network security.
Huawei base stations support Access Control based on 802.1x. The authentication is
unidirectional and is based on Extensible Authentication Protocol-Transport Layer Security
(EAP-TLS). That is, the authentication server performs unidirectional authentication on the
digital certificates of base stations. Figure 2-1shows the network topology for Access Control
based on 802.1x.

3Technical Description
3.1 Operating Principle
Access Control based on 802.1x usually adopts the client/server architecture, as shown in
Figure 2-1. The authentication access equipment receives authentication packets from users
or devices and then forwards the packets to the authentication server. The authentication
server authenticates the identities of the users or devices. If the authentication succeeds, the
data flow of the users or devices can pass through the ports of the authentication access
equipment.
Access Control based on 802.1x involves the following components:
lAuthentication client (a device to be authenticated, such as a base station): initiates an802.1x-based access control procedure. An authentication client is also referred to as a
suppliant. To support port-based access control, the authentication client needs to support
the Extensible Authentication Protocol over LAN (EAPoL).
l Authentication access equipment (such as a LAN switch): receives and forwards EAP
authentication packets between the base station and authentication server at the Media
Access Control (MAC) layer. Authentication access equipment is also referred to as an
authenticator. The authentication access equipment also controls the status (authorized or
unauthorized) of controlled ports based on the authentication result at the authentication
server.
l Authentication server: performs authentication on clients. The servers commonly used
are Remote Authentication Dial In User Service (RADIUS) and Authentication,Authorization and Accounting (AAA) servers.
NOTE
The functions of RADIUS and AAA servers are similar. This document uses the RADIUS server as an
example to describe Access Control based on 802.1x.
Figure 3-1shows the operating principle of Access Control based on 802.1x.

NOTE
Port access entity (PAE) is a port-related protocol entity that processes protocol packets during an
authentication procedure.
A physical Ethernet port of the authentication access equipment consists of two logical ports:
one controlled port and one uncontrolled port:
l Controlled port: A controlled port can be in the unauthorized or authorized state,
depending on the authentication result at the authentication server.
A controlled port in the authorized state is in the bidirectional connectivity state and
data flow can pass through the port.
A controlled port in the unauthorized state does not allow any data to pass through.
l Uncontrolled port: An uncontrolled port is always in the bidirectional connectivity state.Only EAPoL packets can pass through an uncontrolled port. This ensures that the
authentication client can always transmit and receive authentication packets.
During initial access, the base station is not authenticated, and therefore the controlled port is
in the unauthorized state. At this point, only EAPoL packets can pass through the
uncontrolled port and be sent to the authentication server. After the authentication server
authenticates the base station and the authentication access equipment authorizes the
controlled port, the controlled port becomes authorized and data from the base station can
pass through the controlled port in the authorized state. This process ensures that only
authorized users and devices can access the network.
Port-based access control can be based on a physical port (such as the MAC address) or alogical port (such as the VLAN). Huawei base stations support only port-based access control
based on the MAC address. That is, the authentication message sent by a base station contains
the MAC address of the Ethernet port that connects the base station to the transport network.
If authentication succeeds, the authentication access equipment performs access control on
data flow based on this MAC address.
For details about IEEE 802.1x-based access control, see IEEE 802[1].1x-2004.

and the authentication access equipment, EAP data is encapsulated in EAPoL frames so that
the data can be transmitted in the LAN. Between the authentication access equipment and the
authentication server, EAPoL frames are re-encapsulated in EAP over RADIUS (EAPoR)
frames so that the data can be transmitted using the RADIUS protocol.
Figure 3-2shows the protocol stacks for Access Control based on 802.1x.
Figure 3-2Protocol stacks for Access Control based on 802.1x
Access Control based on 802.1x uses the EAP protocol for authentication. The EAP protocol
supports multiple authentication methods. Huawei base stations adopt unidirectional EAP-
TLS authentication, that is, the authentication server authenticates base stations using digital
certificates. TheAMparameter specifies the authentication method used by IEEE 802.1x-
based access control.
In an IEEE 802.1x-based access control procedure, the base station sends its digital certificate
to the RADIUS server in an EAPoL frame. The RADIUS server authenticates the base station
by using the Huawei root certificate or the operator's root certificate.
For details about the EAP protocol, see RFC 3748.
For details about the EAP-TLS protocol, see RFC 2716.

4.1 Typical Network Topology
To implement IEEE 802.1x-based access control, an authentication server and authentication
access equipment (generally a LAN switch directly connected to the base station) supporting
IEEE 802.1x-based access control, need to be deployed in the network. Because Huawei base
station adopts unidirectional EAP-TLS authentication based on IEEE 802.1x and is
preconfigured with Huawei-issued device certificates and Huawei root certificates before
delivery, the authentication server needs to be preconfigured with the Huawei root certificate.
Figure 4-1shows a typical network topology for IEEE 802.1x-based access control.
Figure 4-1Typical network topology for IEEE 802.1x-based access control
IEEE 802.1x-based access control of Ethernet ports can be activated by using the ACT
DOT1Xcommand and deactivated by using the DEA DOT1X command. By default, IEEE
802.1x-based access control is activated on Ethernet ports of base stations before delivery.
4.2 Auto-Discovery with Access Control based on 802.1x
4.2.1 Automatic Base Station Deployment by PnP
When Access Control based on 802.1x is activated in the network, a base station must pass
the IEEE 802.1x-based authentication before automatic deployment by plug and play (PnP).
To ensure the base station's adaptability to the network, after being powered on, Huawei base
stations perform as follows depending on network conditions:
l If the network supports IEEE 802.1x-based access control, and IEEE 802.1x-based
access control is activated on the Ethernet port that connects the base station to the
transport network:
The base station initiates an IEEE 802.1x-based access control procedure. After the IEEE
802.1x-based access control succeeds, the base station sends a Dynamic Host
Configuration Protocol (DHCP) Discover packet to the authentication access equipment
to start the DHCP procedure. After the DHCP procedure is complete, the automatic base
station deployment procedure starts.
l If the network supports IEEE 802.1x-based access control, but IEEE 802.1x-based
access control is deactivated on the Ethernet port that connects the base station to the
transport network:
The base station does not initiate an IEEE 802.1x-based access control procedure.Instead, the base station first sends a DHCP Discover packet and the DHCP module

7/25/2019 Access Control Based on 802.1x(SRAN10.1_01)

queries whether IEEE 802.1x-based access control is activated on the Ethernet port that
connects the base station to the transport network. If IEEE 802.1x-based access control is
deactivated and authentication is not performed, the base station triggers an IEEE
802.1x-based access control procedure. Because the network uses IEEE 802.1x-based
access control, the DHCP Discover packet cannot pass through the authentication access
equipment, and therefore the DHCP procedure fails. The base station waits for the
authentication result. After the IEEE 802.1x-based access control succeeds, the base
station resends a DHCP Discover packet. After the DHCP procedure is complete, the
automatic base station deployment procedure starts.
For example, the main control board of the base station has an incorrect configuration
file, in which IEEE 802.1x-based access control is deactivated on the Ethernet port that
connects the base station to the transport network. In this case, the DHCP procedure
triggers the IEEE 802.1x-based access control procedure during automatic base station
deployment.
l If the network does not support IEEE 802.1x-based access control, and IEEE 802.1x-
based access control is activated on the Ethernet port that connects the base station to the
transport network:
The base station initiates the IEEE 802.1x-based access control procedure for three times
at an interval of 25 seconds. If the base station does not receive any response from the
network, the base station determines that the network does not support IEEE 802.1x-
based access control. The base station then sends a DHCP Discover packet. The DHCP
Discover packet can pass through the authentication access equipment. After the DHCP
procedure is complete, the automatic base station deployment procedure starts.
The rest of this section describes automatic base station deployment by PnP in the preceding
three scenarios.
NOTE
During automatic base station deployment by PnP, the IEEE 802.1x-based access control procedure uses
the preconfigured Huawei-issued device certificate of the base station for authentication.
Scenario 1
Figure 4-2shows automatic base station deployment when the network supports IEEE
802.1x-based access control and IEEE 802.1x-based access control is activated on the
Ethernet port that connects the base station to the transport network.

Figure 4-2Automatic base station deployment (1)
The automatic base station deployment procedure in this scenario is as follows:
1. After the base station is powered on, it sends an EAPoL-Start packet to the
authentication access equipment, to initiate an IEEE 802.1x-based access controlprocedure.
2. The base station, authentication access equipment, and authentication server perform the
IEEE 802.1x-based access control procedure. The base station can initiate the IEEE
802.1x-based access control procedure on the same Ethernet port a maximum of three
times at an interval of 25 seconds.
3. If the IEEE 802.1x-based access control procedure succeeds, the base station initiates a
DHCP procedure. After the DHCP procedure is complete, the automatic base station
deployment procedure starts.
4. If the IEEE 802.1x-based access control procedure fails, the base station initiates a
DHCP procedure. However, the base station does not receive any response to the DHCP
procedure, and therefore the DHCP procedure fails. The base station attempts to initiate
IEEE 802.1x-based access control and DHCP procedures on the next Ethernet port.
NOTE
In the IEEE 802.1x-based access control procedure, the EAPoL-Start packet is a multicast packet and its
destination MAC address is 01-80-C2-00-00-03; other packets are unicast packets.
Scenario 2
Figure 4-3shows automatic base station deployment when the network supports IEEE
802.1x-based access control but IEEE 802.1x-based access control is deactivated on the
Ethernet port that connects the base station to the transport network.

The automatic base station deployment procedure in this scenario is as follows:
1. After a base station is powered on, it sends a DHCP Discover packet to the
authentication access equipment because IEEE 802.1x-based access control is
deactivated on the Ethernet port that connects the base station to the transport network.
2. The DHCP module queries whether IEEE 802.1x-based access control is activated on the
Ethernet port that connects the base station to the transport network. If IEEE 802.1x-
based access control is deactivated and authentication is not performed, the base station
triggers an IEEE 802.1x-based access control procedure on this Ethernet port.
3. Because the controlled port of the authentication access equipment is in the unauthorized
state, the base station does not receive any DHCP response. The DHCP procedure fails.
The base station waits for the authentication result.
4. When the IEEE 802.1x-based access control procedure succeeds, the base station resends
a DHCP Discover packet through the Ethernet port. After the DHCP procedure is
complete, the automatic base station deployment procedure starts.
Scenario 3
Figure 4-4shows automatic base station deployment when the network does not support
IEEE 802.1x-based access control and IEEE 802.1x-based access control is activated on the

The automatic base station deployment procedure in this scenario is as follows:
1. After the base station is powered on, it initiates an IEEE 802.1x-based access control
procedure. The base station resends the EAPoL-Start packet three times at an interval of
25 seconds but does not receive any response. Therefore, the base station determines that
the network does not support IEEE 802.1x-based access control.
2. The base station sends a DHCP Discover packet to the authentication access equipment.
3. After the DHCP procedure is complete, the automatic base station deployment procedure
starts.
4.2.2 Application on Existing Base Stations
After a base station obtains the configuration file, it restarts. If the state of its Ethernet port
changes from DOWN to UP and IEEE 802.1x-based access control is activated on this
Ethernet port, the base station initiates an IEEE 802.1x-based access control procedure. By
default, IEEE 802.1x-based access control and SSL authentication use the same certificate:
l If the certificate used for SSL authentication in the configuration file is set to the
operator-issued device certificate, the IEEE 802.1x-based access control procedure uses
the operator-issued device certificate to authenticate the base station.
l If the certificate used for SSL authentication in the configuration file is set to the
Huawei-issued device certificate, the IEEE 802.1x-based access control procedure uses
Huawei-issued device certificate to authenticate the base station.
l If the SSL authentication method is cryptonym authentication, by default the IEEE802.1x-based access control procedure uses the Huawei-issued device certificate to
authenticate the base station.
NOTE
During base station deployment using a USB flash drive, the certificate used in the IEEE 802.1x-based
access control procedure is specified in the configuration file. Because the base station is preconfigured
with the Huawei-issued device certificate, the certificate for SSL authentication can be set only to
Huawei-issued device certificate in the configuration file. If the certificate for SSL authentication is set
to the operator-issued device certificate, the IEEE 802.1x-based access control procedure fails.

7.1 When to Use Access Control based on 802.1x
If the operator's transport network is located in an open network, the devices in the transport
network are vulnerable to unauthorized access and malicious attacks. In this case, it is
recommended that the Access Control based on 802.1x feature be activated to authenticate the
users or devices that attempt to access the transport network. This feature prevents
unauthorized users and devices from accessing the network and ensures transport network
security.
The Access Control based on 802.1x feature uses the Huawei-issued device certificate to
authenticate the base station. Therefore, the PKI feature also needs to be activated.
7.2 Required Information
Huawei base stations support only unidirectional EAP-TLS authentication and port-basedaccess control based on the MAC address. Therefore, before you activate the Access Control
based on 802.1x feature, check whether the authentication server supports unidirectional
EAP-TLS authentication and whether the authentication access equipment supports port-
based access control based on the MAC address.
l If the customer requires that Access Control based on 802.1x use the Huawei-issued
device certificate to authenticate the base station, the PKI feature does not need to be
deployed in the network.
l If the customer requires that Access Control based on 802.1x use the operator-issued
device certificate to authenticate the base station, the PKI feature needs to be deployed in
the network. For details about how to deploy the PKI feature, seePKI Feature
Parameter Description.

NOTE
l When you deploy this feature on a multimode base station, activate the feature only on the Ethernet
port that connects the base station to the transport network. The data preparation and initial
configuration of the multimode base station are the same as those of a single-mode base station.
l When a base station is working normally, the certificate used by IEEE 802.1x-based access control
is the same as that used by SSL authentication. For details about how to configure the certificate for
SSL authentication, see the "Engineering Guidelines" section in SSL Feature Parameter
Description. If no certificate is configured for SSL authentication, IEEE 802.1x-based access control
uses the Huawei-issued device certificate by default.
