Predefined user roles

network-admin

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.

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.

Examples

# Configure VLAN 100 as the Auth-Fail VLAN on Ten-GigabitEthernet 1/0/1.

Parameters

authfail-vsi-name: Specifies the name of the 802.1X Auth-Fail VSI on the port, a case-sensitive string of 1 to 31 characters.

Usage guidelines

This command takes effect only on 802.1X-enabled ports that perform MAC-based access control.

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

You can configure only one 802.1X Auth-Fail VSI on a port. The 802.1X Auth-Fail VSIs on different ports can be different.

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

Predefined user roles

network-admin

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. 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.

Examples

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

Parameters

critical-vlan-id: Specifies the ID of the 802.1X critical 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 critical VLAN accommodates users that have failed 802.1X authentication because all the RADIUS servers in their ISP domains are unreachable. Users in the critical VLAN can access a limited set of network resources depending on the configuration.

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

On a port, the 802.1X critical 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 critical VLAN, you must first use the undo dot1x critical vlan command.

Parameters

critical-vsi-name: Specifies the name of the 802.1X critical VSI on the port, a case-sensitive string of 1 to 31 characters.

Usage guidelines

This command takes effect only on 802.1X-enabled ports that perform MAC-based access control.

An 802.1X critical VSI accommodates users that have failed 802.1X authentication because all the RADIUS servers in their ISP domains are unreachable. Users in the 802.1X critical VSI can access a limited set of network resources in the VXLAN associated with this VSI.

You can configure only one 802.1X critical VSI on a port. The 802.1X critical VSIs on different ports can be different.

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

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 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.

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.

dot1x port-method

Use dot1x port-method to specify an access control method for the port.

Use undo dot1x port-method to restore the default.

Syntax

dot1x port-method { macbased | portbased }

undo dot1x port-method

Default

MAC-based access control applies.

network-admin

Parameters

macbased: Uses MAC-based access control on the port to separately authenticate each user attempting to access the network. Using this method, when an authenticated user logs off, no other online users are affected.

portbased: Uses port-based access control on the port. Using this method, once an 802.1X user passes authentication on the port, any subsequent user can access the network through the port without authentication. When the authenticated user logs off, all other users are logged off.

Usage guidelines

Changing the access control method of a port will log off all online 802.1X users immediately on that port.

Examples

# Configure Ten-GigabitEthernet 1/0/1 to implement port-based access control.

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 timer. 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 timer. 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.

Examples

# Set the maximum number of attempts to 9 for sending an authentication request to a client.

<Sysname> system-view

[Sysname] dot1x retry 9

Parameters

ead-timeout ead-timeout-value: Sets the EAD rule timer in minutes. The value range for the ead-timeout-value argument is 1 to 1440.

handshake-period handshake-period-value: Sets the handshake timer in seconds. The value range for the handshake-period-value argument is 5 to 1024.

quiet-period quiet-period-value: Sets the quiet timer in seconds. The value range for the quiet-period-value argument is 10 to 120.

reauth-period reauth-period-value: Sets the periodic reauthentication timer in seconds. The value range for the reauth-period-value argument is 60 to 7200.

server-timeout server-timeout-value: Sets the server timeout timer in seconds. The value range for the server-timeout-value argument is 100 to 300.

supp-timeout supp-timeout-value: Sets the client timeout timer in seconds. The value range for the supp-timeout-value argument is 1 to 120.

tx-period tx-period-value: Sets the username request timeout timer in seconds. The value range for the tx-period-value argument is 1 to 120.

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 within the timer, 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.

· 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.

· 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.

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.

Examples

# Set the server timeout timer to 150 seconds.

Predefined user roles

network-admin

Parameters

reauth-period-value: Sets the 802.1X periodic reauthentication timer in seconds. The value range for the reauth-period-value argument is 60 to 7200.

Usage guidelines

The device reauthenticates online 802.1X users on a port at the specified periodic reauthentication interval when the port is enabled with periodic reauthentication. To enable periodic reauthentication on a port, use the dot1x re-authenticate command.

A change to the periodic reauthentication timer applies to online users only after the old timer expires.

The device selects a periodic reauthentication timer for 802.1X reauthentication in the following order:

1. Server-assigned reauthentication timer.

2. Port-specific reauthentication timer.

3. Global reauthentication timer.

4. Default reauthentication timer.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

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.

Examples

# Enable the unicast trigger feature on Ten-GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1
