Predefined user roles

network-admin

mdc-admin

Parameters

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

pap: Sets 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 H3C iNode 802.1X client.

¡ CHAP transports username in plaintext and encrypted password 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-TL, 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.

Views

System view

Predefined user roles

network-admin

mdc-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 who 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.

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

If you do not specify any keyword, this command and its undo form apply to both EAPOL-triggered and new MAC-triggered 802.1X guest VLAN assignment delay on a port.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

mdc-admin

Usage guidelines

The SmartOn feature and the online user handshake feature are mutually exclusive.

When a SmartOn-enabled port receives an EAPOL-Start packet from an 802.1X client, it sends a unicast EAP-Request/Notification packet to the client. The client will respond with an EAP-Response/Notification packet, which contains the SmartOn switch ID and the MD5 digest of the SmartOn password. The device compares the digest in the packet with the digest on the device. If they are the same, the device continues to perform 802.1X authentication for the client. Otherwise, the device denies the client's 802.1X authentication request.

Examples

# Enable the SmartOn feature on port GigabitEthernet 1/0/1.

Parameters

cipher cipher-string: Sets a ciphertext password. The cipher-string argument is a case-sensitive string of 1 to 53 characters.

simple plain-string: Sets a plaintext password. The plain-string argument is a case-sensitive plaintext string of 1 to 16 characters.

Usage guidelines

The device checks the MD5 digest of the SmartOn password in each received EAP-Response/Notification packet. If the digest is different from the SmartOn password digest on the device, the device stops the 802.1X authentication process for the client that sends this packet.

For security purposes, all passwords, including passwords configured in plain text, are saved in ciphertext.

If you execute the dot1x smarton password command multiple times, the most recent configuration takes effect.

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 periodic reauthentication timer does not take effect if the server has assigned a session timeout timer to the device.

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 periodic online user reauthentication on a port, use the dot1x re-authenticate command. The change to the periodic reauthentication timer applies to the users who have been online only after the old timer expires.

· 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 access device retransmits the request to the server.

· 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.
