Predefined user roles

network-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 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.

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.

Syntax

dot1x critical eapol

undo dot1x critical eapol

Default

The device sends an EAP-Failure packet to an 802.1X client when the 802.1X user is assigned to the critical VLAN.

Views

Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

Typically, 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 of the device if they have received an EAP-Failure packet. As a result, reauthentication fails for these clients when an authentication server is reachable.

This command enables 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. This operation ensures that all 802.1X clients can perform reauthentication.

Examples

# Configure Ten-GigabitEthernet 1/0/1 to send EAP-Success packets to 802.1X clients when the client users are assigned to the critical VLAN.

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.

undo dot1x domain-delimiter

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 typically use the username+domain-delimiter+domain-name format (for example, 123@abc). However, if the domain delimiter is the backslash (\), usernames that include domain names use the domain-name\username format.

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

This command enables the device to send 802.1X protocol packets out of an 802.1X-enabled port without VLAN tags. Use this command to prevent terminal devices connected to the port from failing 802.1X authentication when the following conditions exist:

· The port is configured as a tagged member of the port VLAN.

· The terminal devices send 802.1X protocol packets without VLAN tags for authentication and cannot identify 802.1X protocol packets with VLAN tags.

In other situations, do not use this command.

network-admin

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 delays on a port.

Parameters

max-retry-value: Sets 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.

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 global 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.

· Global 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 global periodic reauthentication timer applies to the users that 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.

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 Identity EAP/Request 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.
