Overview

IEEE 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.

Technical 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: l

Authentication client (a device to be authenticated, such as a base station): initiates an 802.1x-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 3-1 shows the operating principle of Access Control based on 802.1x.

Issue 01 (2013-04-28)

Figure 3-1 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 a logical 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.

3.2 Protocol Stacks In IEEE 802.1x-based access control, the authentication client and the authentication server exchange authentication messages using the EAP protocol. Between the authentication client Issue 01 (2013-04-28)

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 3-2 shows the protocol stacks for Access Control based on 802.1x. Figure 3-2 Protocol 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. The AM parameter 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.

Application of Access Control based on 802.1x This chapter describes the application of IEEE 802.1x-based access control on a base station.

Issue 01 (2013-04-28)

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 4-1 shows a typical network topology for IEEE 802.1x-based access control. Figure 4-1 Typical 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 DOT1X command 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 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 4-2 shows automatic base station deployment when the network supports IEEE 802.1xbased access control and IEEE 802.1x-based access control is activated on the Ethernet port that connects the base station to the transport network.

Issue 01 (2013-04-28)

Figure 4-2 Automatic 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 control procedure.

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 802.1xbased 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 802.1xbased 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 4-3 shows automatic base station deployment when the network supports IEEE 802.1xbased access control but IEEE 802.1x-based access control is deactivated on the Ethernet port that connects the base station to the transport network.

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 4-4 shows 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 Ethernet port that connects the base station to the transport network.

Issue 01 (2013-04-28)


11





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 operatorissued device certificate, the IEEE 802.1x-based access control procedure uses the operatorissued device certificate to authenticate the base station.

l

If the certificate used for SSL authentication in the configuration file is set to the Huaweiissued device certificate, the IEEE 802.1x-based access control procedure uses Huaweiissued device certificate to authenticate the base station.

l

If the SSL authentication method is cryptonym authentication, by default the IEEE 802.1xbased 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 Huaweiissued 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-based access 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, see PKI Feature Parameter Description.

This parameter indicates the authentication method used by the Access Control based on 802.1x feature. The feature supports EAP-TLS authentication.

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 Huaweiissued device certificate by default.

l For an Ethernet port on which Access Control based on 802.1X is activated, set the Active Sign parameter to ACTIVE. l For an Ethernet port on which Access Control based on 802.1X is deactivated, set the Active Sign parameter to DEACTIVE and leave the Authentic Method parameter unspecified.

For instructions about performing batch configuration for each base station, see the following sections in 3900 Series Base Station Initial Configuration Guide. l

For a NodeB: Creating NodeBs in Batches

l

For an eNodeB: Creating eNodeBs in Batches

l

For a separate-MPT multimode base station: Creating Separate-MPT Multimode Base Stations in Batches (Summary Data File)

l

For an eGBTS or a co-MPT multimode base station: Creating Co-MPT Multimode Base Stations in Batches (Summary Data File) NOTE

l eGBTS refers to a base station deployed with UMPT_G. l NodeB refers to a base station deployed with WMPT or UMPT_U. l eNodeB refers to a base station deployed with LMPT or UMPT_L. l Co-MPT multimode base station refers to a base station deployed with UMPT_GU, UMPT_GL, UMPT_UL, or UMPT_GUL, and it functionally corresponds to any combination of eGBTS, NodeB, and eNodeB. For example, Co-MPT multimode base station deployed with UMPT_GU functionally corresponds to the combination of eGBTS and NodeB. l Separate-MPT multimode base station refers to a base station on which different modes use different main control boards. For example, base stations deployed with GTMU and WMPT are called separateMPT GSM/UMTS dual-mode base station.

Using the CME to Perform Batch Configuration for Existing Base Stations Batch reconfiguration using the CME is the recommended method to activate a feature on existing base stations. This method reconfigures all data, except neighbor relationships, for multiple base stations in a single procedure. The procedure is as follows: Step 1 Choose CME > Customize Summary Data File from the main menu of an M2000 client, or choose Advanced > Customize Summary Data File from the main menu of a CME client, to customize a summary data file for batch reconfiguration.

NOTE

For context-sensitive help on a current task in the client, press F1.

Step 2 Choose CME >Base Station Bulk Configuration > Export Data from the main menu of the M2000 client, or choose Advanced > Base Station Bulk Configuration > Export Data from the main menu of the CME client, to export the base station data stored on the CME into the customized summary data file. Step 3 In the summary data file, set the parameters in the MOs listed in Table 7-2 and close the file. Step 4 Choose CME > Base Station Bulk Configuration > Import Data from the main menu of the M2000 client, or choose Advanced >Base Station Bulk Configuration > Import Data from the main menu of the CME client, to import the summary data file into the CME. ----End

7.4.5 Activation Observation Run the DSP DOT1X command to query whether Access Control based on 802.1x is activated on the Ethernet port that connects the base station to the transport network. Check the value of the Authentic State parameter in the command output. If the value of this parameter is Authenticate Succeed, the port has passed IEEE 802.1x-based authentication. The following is an example: DSP DOT1X: CN=0, SRN=0, SN=6, SBT=BASE_BOARD, PN=0;%% RETCODE = 0 Operation succeeded. Display 802.1x -------------Cabinet No. = 0 Subrack No. = 0 Slot No. = 7 Subboard Type = Base Board Port No. = 0 Active Sign = Active Authentic Method = EAP-TLS authentic method Authentic State = Authenticate Succeed Authentic Succeed Number = 1 Fail Number = 0 Fail Reason = 0 Send EAP Packet Number = 7 Receive EAP Packet Number = 7 Abnormal Packet Number = 0 (Number of results = 1) NOTE


7.4.6 Deactivation Using MML Commands Run the MML command DEA DOT1X to deactivate Access Control based on 802.1x on the Ethernet port that connects the base station to the transport network.

MML Command Examples //Deactivating Access Control based on 802.1x DEA DOT1X: SN=7, SBT=BASE_BOARD, PN=0; NOTE


Using the CME to Perform Single Configuration None

Using the CME to Perform Batch Configuration The procedure for feature deactivation is similar to that for feature activation. The only difference is the parameter setting, which is described in Table 7-2.

7.5 Parameter Optimization None.

7.6 Troubleshooting After Access Control based on 802.1x is activated, the base station may report ALM-26831 802.1x Authentication Failure. For details about how to clear these alarms for each type of base station, see the following sections in 3900 Series Base Station Alarm Reference: l
