Parameters

chap: Configures the access device to perform Extensible Authentication Protocol (EAP) termination and use the Challenge Handshake Authentication Protocol (CHAP) to communicate with the RADIUS server.

eap: Configures the access device to relay EAP packets, and supports any of the EAP authentication methods to communicate with the RADIUS server.

pap: Configures the access device to perform EAP termination and use the Password Authentication Protocol (PAP) to communicate with the RADIUS server.

Usage guidelines

The access device terminates or relays EAP packets.

·          In EAP termination mode—The access device re-encapsulates and sends the authentication data from the client in standard RADIUS packets to the RADIUS server. The device performs either CHAP or PAP authentication with the RADIUS server. In this mode, the RADIUS server supports only MD5-Challenge EAP authentication and the username and password EAP authentication initiated by an iNode client.

¡  PAP transports usernames and passwords in plain text. The authentication method applies to scenarios that do not require high security. To use PAP, the client can be an iNode 802.1X client.

¡  CHAP transports usernames in plain text and passwords in encrypted form over the network. CHAP is more secure than PAP.

·          In EAP relay mode—The access device relays EAP messages between the client and the RADIUS server. The EAP relay mode supports multiple EAP authentication methods, such as MD5-Challenge, EAP-TLS, and PEAP. To use this mode, make sure the RADIUS server meets the following requirements:

¡  Supports the EAP-Message and Message-Authenticator attributes.

¡  Uses the same EAP authentication method as the client.

If this mode is used, the user-name-format command configured in RADIUS scheme view does not take effect. For more information about the user-name-format command, see "RADIUS commands."

If RADIUS authentication is used, you must configure the access device to use the same authentication method (PAP, CHAP, or EAP) as the RADIUS server.

Examples

# Enable the access device to terminate EAP packets and perform PAP authentication with the RADIUS server.

Use undo dot1x auth-fail eapol to restore the default.

Syntax

dot1x auth-fail eapol

undo dot1x auth-fail eapol

Default

Some 802.1X clients cannot send DHCP requests for IP addresses after they receive EAP-Failure packets. To have these clients obtain IP addresses to access authorized resources after they are assigned to the 802.1X Auth-Fail VLAN or VSI, use this feature.

Examples

# Enable the device to send an EAP-Success packet to a client when the client user is assigned to the 802.1X Auth-Fail VLAN or VSI on Twenty-FiveGigE 1/0/1.

Parameters

authfail-vlan-id: Specifies the ID of the 802.1X Auth-Fail VLAN on the port. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created.

Usage guidelines

An 802.1X Auth-Fail VLAN accommodates users that have failed 802.1X authentication for any reason other than unreachable servers. Users in the Auth-Fail VLAN can access a limited set of network resources.

You cannot specify a VLAN as both a super VLAN and an 802.1X Auth-Fail VLAN on a port. For more information about super VLANs, see Layer 2—LAN Switching Configuration Guide.

On a port, the 802.1X Auth-Fail VLAN configuration is mutually exclusive with the 802.1X guest VSI, 802.1X Auth-Fail VSI, and 802.1X critical VSI settings.

To delete a VLAN that has been configured as an 802.1X Auth-Fail VLAN, you must first use the undo dot1x auth-fail vlan command.

 Usage guidelines

By default, the device sends EAP-Failure packets to 802.1X clients when the client users are assigned to the 802.1X critical VLAN or VSI. Some 802.1X clients, such as Windows built-in 802.1X clients, cannot respond to the EAP-Request/Identity packets from the device for reauthentication if they have received an EAP-Failure packet. As a result, reauthentication for these clients will fail after the authentication server becomes reachable.

To avoid this situation, enable the device to send EAP-Success packets instead of EAP-Failure packets to 802.1X clients when the client users are assigned to the 802.1X critical VLAN or VSI.

Examples

# Send an EAP-Success packet to a client when the 802.1X client user is assigned to the 802.1X critical VLAN or VSI on Twenty-FiveGigE 1/0/1.

Usage guidelines

The 802.1X critical voice VLAN on a port accommodates 802.1X voice users that have failed authentication because none of the RADIUS servers in their ISP domain are reachable.

Before you enable the 802.1X critical voice VLAN feature on the port, make sure the following requirements are met:

·          The port is configured with the voice VLAN.

To configure a voice VLAN on a port, use the voice-vlan enable command (see Layer 2—LAN Switching Command Reference).

·          LLDP is enabled both globally and on the port.

The device uses LLDP to identify voice users. For information about LLDP commands, see Layer 2—LAN Switching Command Reference.

Default

The device supports only the at sign (@) delimiter for 802.1X users.

Views

System view

Predefined user roles

network-admin

Parameters

string: Specifies a set of 1 to 16 domain name delimiters for 802.1X users. No space is required between delimiters. Available delimiters include the at sign (@), backslash (\), dot (.), and forward slash (/). If you want to use backslash (\) as the domain name delimiter, you must enter the escape character (\) along with the backslash (\) sign.

Usage guidelines

Any character in the configured set can be used as the domain name delimiter for 802.1X authentication users. Usernames that include domain names can use the format of username@domain-name, domain-name\username, username.domain-name, or username/domain-name.

The delimiter set you configured overrides the default setting. If the at sign (@) is not included in the delimiter set, the device does not support the 802.1X users that use this sign as the domain name delimiter.

If a username string contains multiple configured delimiters, the device takes the rightmost delimiter in the username string as the domain name delimiter. For example, if you configure the forward slash (/), dot (.), and backslash (\) as delimiters, the domain name delimiter for the username string 121.123/22\@abc is the backslash (\). The username is @abc and the domain name is 121.123/22.

Examples

# Specify the at sign (@) and forward slash (/) as domain name delimiters.

Usage guidelines

The EAD assistant feature enables the access device to redirect the HTTP or HTTPS requests of a user to a URL to download and install EAD client. This feature eliminates the tedious job of the administrator to deploy EAD clients.

For the EAD assistant feature to take effect on a port, you must set the port authorization mode to auto.

The feature is mutually exclusive with MAC authentication and port security. You must disable MAC authentication and port security globally before you enable the EAD assistant feature.

To redirect the HTTPS requests of 802.1X users, use the http-redirect https-port command to specify the HTTPS redirect listening port. For information about the http-redirect https-port command, see HTTP redirect commands in Layer 3—IP Services Command Reference.

Parameters

url-string: Specifies the redirect URL, a case-sensitive string of 1 to 256 characters in the format http://string or https://string. If the specified URL does not start with http:// or https://, the device prefixes the specified URL with http://. Because the URL string can contain question marks (?), you cannot obtain help information by entering a question mark at the position of this argument.

Usage guidelines

When an unauthenticated user uses a Web browser to access any network other than the free IP, the device redirects the HTTP or HTTPS requests of the user to the redirect URL.

The redirect URL must be on the free IP subnet.

If you execute this command multiple times, the most recent configuration takes effect.

To redirect the HTTPS requests of 802.1X users, use the http-redirect https-port command to specify the HTTPS redirect listening port. For information about the http-redirect https-port command, see HTTP redirect commands in Layer 3—IP Services Command Reference.

Examples

# Configure the redirect URL as http://test.com.

network-admin

Parameters

eap-tls-max-length: Sets the maximum EAP-TLS fragment size in bytes. The value range is 100 to 1500.

Usage guidelines

802.1X EAP-TLS fragmentation takes effect only when EAP relay mode is used.

When the device uses EAP-TLS authentication method in EAP relay mode, the RADIUS packets might exceed the maximum packet size supported by the RADIUS server. This situation typically occurs when long EAP-TLS messages are encapsulated in the EAP-Message attribute of the RADIUS packet sent to the RADIUS server.

To avoid authentication failures caused by oversized packets, fragment the EAP-TLS messages depending on the maximum RADIUS packet size supported by the remote RADIUS server.

For example, the maximum packet length allowed by the server is 1200 bytes and the length of a RADIUS packet (excluding the EAP-Message attribute) is 800 bytes. To make sure the maximum length of a RADIUS packet does not exceed 1200 bytes, you must set the maximum length of an EAP-TLS fragment to a value less than 400 bytes.

Examples

# Set the maximum EAP-TLS fragment size to 400 bytes.

Parameters

guest-vlan-id: Specifies the ID of the 802.1X guest VLAN. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created.

Usage guidelines

An 802.1X guest VLAN accommodates users that have not performed 802.1X authentication. In the guest VLAN, users can access a limited set of network resources, such as a software server, to download anti-virus software and system patches.

You cannot specify a VLAN as both a super VLAN and an 802.1X guest VLAN on a port. For more information about super VLANs, see Layer 2—LAN Switching Configuration Guide.

On a port, the 802.1X guest VLAN configuration is mutually exclusive with the 802.1X guest VSI, 802.1X Auth-Fail VSI, and 802.1X critical VSI settings.

To delete a VLAN that has been configured as a guest VLAN, you must use the undo dot1x guest-vlan command first.

Parameters

eapol: Specifies EAPOL-triggered 802.1X guest VLAN assignment delay. This keyword takes effect if 802.1X authentication is triggered by EAPOL-Start packets.

new-mac: Specifies new MAC-triggered 802.1X guest VLAN assignment delay. This keyword takes effect if 802.1X authentication is triggered by packets from unknown MAC addresses.

Usage guidelines

This command enables the device to delay assigning an 802.1X-enabled port to the 802.1X guest VLAN when 802.1X authentication is triggered on the port.

To use this feature, the 802.1X-enabled port must perform MAC-based access control.

When 802.1X authentication is triggered on a port, the device performs the following operations:

1.        Sends a unicast EAP-Request/Identity packet to the MAC address that triggers the authentication.

2.        Retransmits the packet if no response has been received within the username request timeout interval set by using the dot1x timer tx-period command.

3.        Assigns the port to the 802.1X guest VLAN after the maximum number of request attempts set by using the dot1x retry command is reached.

If you use the undo command without any keyword, the command disables both EAPOL-triggered and new MAC-triggered 802.1X guest VLAN assignment delay on a port.

Predefined user roles

network-admin

Usage guidelines

The 802.1X offline detection feature monitors the online status of 802.1X users. This feature uses an offline detect timer to set the interval that the device must wait for traffic from a user before the device determines that the user is idle. If the device has not received traffic from a user before the timer expires, the device logs off that user and requests the accounting server to stop accounting for the user.

To have 802.1X offline detection take effect, you must configure the port to perform MAC-based access control. If you change the port access mode to port-based, the 802.1X offline detection feature cannot take effect.

To set the offline detect timer, use the dot1x timer command.

Parameters

retries: Specifies the maximum number of attempts for sending an authentication request to a client. The value range is 1 to 10.

Usage guidelines

The access device retransmits an authentication request to a client in any of the following situations:

·          The device does not receive any responses from the client within the username request timeout interval. The timer is set by using the dot1x timer tx-period tx-period-value command for the EAP-Request/Identity packet.

·          The device does not receive any responses from the client within the client timeout interval. The timer is set by using the dot1x timer supp-timeout supp-timeout-value command for the EAP-Request/MD5-Challenge packet.

The access device stops retransmitting the request, if it has made the maximum number of request transmission attempts but still received no response.

Usage guidelines

IMPORTANT

IMPORTANT:

This command takes effect only when the device uses an IMC RADIUS server to authenticate 802.1X users.

To ensure that the RADIUS server maintains the same online 802.1X user information as the device after the server state changes from unreachable to reachable, use this feature.

This feature synchronizes online 802.1X user information between the device and the RADIUS server when the RADIUS server state is detected having changed from unreachable to reachable.

When synchronizing online 802.1X user information on a port with the RADIUS server, the device initiates 802.1X authentication in turn for each authenticated online 802.1X user to the RADIUS server.

If synchronization fails for an online user, the device logs off that user unless the failure occurs because the server has become unreachable again.

The amount of time required to complete online user synchronization increases as the number of online users grows. This might result in an increased delay for new 802.1X users and users in the critical VLAN or VSI to authenticate or reauthenticate to the RADIUS server and come online.

To have this feature take effect, you must use it in conjunction with the RADIUS server status detection feature, which is configurable with the radius-server test-profile command. When you configure this feature, make sure the detection interval is shorter than the RADIUS server quiet timer configured by using the timer quiet command in RADIUS scheme view. The server state changes to active on expiration of the quiet timer regardless of its actual reachability. Setting a shorter detection interval than the quiet timer prevents the RADIUS server status detection feature from falsely reporting the server reachability.

For more information about the RADIUS server status detection feature, see AAA configuration in Security Configuration Guide.

aging-time-value: Sets the user aging timer. The value range is 60 to 2147483647 seconds.

Usage guidelines

In most cases, the default settings are sufficient. You can edit the timers, depending on the network conditions.

·          In a low-speed network, increase the client timeout timer.

·          In a vulnerable network, set the quiet timer to a high value.

·          In a high-performance network with quick authentication response, set the quiet timer to a low value.

·          In a network with authentication servers of different performance, adjust the server timeout timer.

The network device uses the following 802.1X timers:

·          EAD rule timer (ead-timeout)—Sets the lifetime of each EAD rule. When the timer expires or the user passes authentication, the rule is removed. If users fail to download the EAD client or fail to pass authentication before the timer expires, they must reconnect to the network to access the free IP.

·          Handshake timer (handshake-period)—Sets the interval at which the access device sends client handshake requests to check the online status of a client that has passed authentication. If the device does not receive a response after sending the maximum number of handshake requests, it considers that the client has logged off.

·          Offline detect timer (offline-detect)—Sets the interval that the device must wait for traffic from a user before the device determines that the user is idle. If the device has not received traffic from a user before the timer expires, the device logs off that user and requests the accounting server to stop accounting for the user. This timer takes effect only when the 802.1X offline detection feature is enabled.

·          Quiet timer (quiet-period)—Starts when a client fails authentication. The access device must wait the time period before it can process the authentication attempts from the client.

·          Periodic reauthentication timer (reauth-period)—Sets the interval at which the network device periodically reauthenticates online 802.1X users. To enable 802.1X periodic reauthentication on a port, use the dot1x re-authenticate command.

·          Server timeout timer (server-timeout)—Starts when the access device sends a RADIUS Access-Request packet to the authentication server. If no response is received when this timer expires, the 802.1X authentication fails.

To avoid forced logoff before the server timeout timer expires, set the server timeout timer to a value that is lower than or equal to the product of the following values:

¡  The maximum number of RADIUS packet transmission attempts set by using the retry command in RADIUS scheme view.

¡  The RADIUS server response timeout timer set by using the timer response-timeout command in RADIUS scheme view.

For information about setting the maximum number of RADIUS packet transmission attempts and the RADIUS server response timeout timer, see AAA configuration in Security Configuration Guide.

·          Client timeout timer (supp-timeout)—Starts when the access device sends an EAP-Request/MD5-Challenge packet to a client. If no response is received when this timer expires, the access device retransmits the request to the client.

·          Username request timeout timer (tx-period)—Starts when the device sends an EAP-Request/Identity packet to a client in response to an authentication request. If the device does not receive a response before this timer expires, it retransmits the request. The timer also sets the interval at which the network device sends multicast EAP-Request/Identity packets to detect clients that cannot actively request authentication.

·          User aging timer (user-aging)—Sets the user aging timer for a type of 802.1X VLAN or VSI.

If you enable 802.1X unauthenticated user aging, you can set a user aging timer for Auth-Fail, critical, or guest VLANs or VSIs. The user aging timer for a type of 802.1X VLAN or VSI determines how long a user can stay in that type of VLAN or VSI.

For more information about how user aging operates, see the usage guidelines for the dot1x unauthenticated-user aging enable command.

Do not set a user aging timer to an integral multiple of the username request timeout timer (the dot1x timer tx-period command). If you do so, the aging timer will not take effect.

The change to the periodic reauthentication timer applies to the users that have been online only after the old timer expires. Other timer changes take effect immediately on the device.

For the device to take action on 802.1X users as expected, do not set the offline detect timer to the same value as either of the following timers:

·          Handshake timer (set by using the dot1x timer handshake-period command).

·          Periodic reauthentication timer (set by using the dot1x timer reauth-period command).

Usage guidelines

802.1X unauthenticated user aging applies to users added to 802.1X guest, critical, or Auth-Fail VLANs or VSIs because they have not been authenticated or have failed authentication.

When a user in one of those VLANs or VSIs ages out, the device removes the user from the VLAN or VSI and deletes the MAC address entry for the user from the access port.

The 802.1X user aging mechanism on a port depends on its access control mode.

·          If the port uses port-based access control, a user aging timer starts when the port is assigned to the critical or Auth-Fail VLAN or VSI. When the aging timer expires, the port is removed from the VLAN or VSI and all MAC address entries for users in the VLAN or VSI are also removed.

·          If the port uses MAC-based access control, a user aging timer starts for each 802.1X user when they are assigned to the Auth-Fail, critical, or guest VLAN or VSI. When the aging timer for a user expires, the device removes that user from the VLAN or VSI.

For users in one of those VLANs or VSIs on one port to be authenticated successfully and come online on another port, enable this feature. In any other scenarios, disable this feature as a best practice.

The removed users will be unable to access any network resources until after another authentication is triggered.

Usage guidelines

The unicast trigger feature enables the access device to initiate 802.1X authentication when the device receives a data frame from an unknown source MAC address. The device sends a unicast EAP-Request/Identity packet to the unknown source MAC address. It will retransmit the packet if it does not receive any responses within a period of time (set by using the dot1x timer tx-period command). This process continues until the maximum number of request attempts (set by using the dot1x retry command) is reached.

As a best practice, do not use the unicast trigger on a port that performs port-based access control. If you do so, users on the port might fail to come online correctly.

Examples

# Enable the unicast trigger feature on Twenty-FiveGigE 1/0/1.

Parameters

interface interface-type interface-number: Specifies a port by its type and number.

mac mac-address: Specifies an 802.1X user by its MAC address. The mac-address argument is in the format of H-H-H.

username username: Specifies an 802.1X user by its name. The username argument is a case-sensitive string of 1 to 253 characters.

vlan vlan-id: Specifies a VLAN by its VLAN ID. The value range for the vlan-id argument is 1 to 4094.

vsi vsi-name: Specifies a VSI by its name. The vsi-name argument is a case-sensitive string of 1 to 31 characters.

Usage guidelines

Use this command to log off the specified 802.1X users and clear information about these users from the device. These users must perform 802.1X authentication to come online again.

If you specify a VSI, this command logs off an 802.1X user if that user has passed authentication and its authorization VSI is the specified VSI.

If you specify a VLAN, this command logs off the following 802.1X users:

·          Users that have passed 802.1X authentication and have been assigned the specified VLAN as the authorization VLAN.

·          Users that have just passed 802.1X authentication and are to be assigned the specified VLAN as the authorization VLAN.

·          Users that are performing 802.1X authentication in the specified VLAN.

If you do not specify any parameters, this command logs off all 802.1X users on the device.

Examples

# Log off all 802.1X users on Twenty-FiveGigE 1/0/1.

<Sysname> reset dot1x access-user interface twenty-fivegige 1/0/1
