Usage guidelines

IMPORTANT

IMPORTANT:

This command can only operate in conjunction with an IMC server.

 

To avoid IP conflicts that result from changes to static IP addresses, use this command on a port that has MAC authentication users that use static IP addresses.

This command adds user IP addresses to the MAC authentication requests sent to the authentication server. When MAC authentication is triggered for a user, the device checks the user's IP address for invalidity.

·          If the IP address is valid, the device sends a MAC authentication request with the IP address included.

·          If the IP address is not a valid host IP address or the triggering packet does not contain an IP address, the device does not initiate MAC authentication.

·          If the packet is a DHCP packet with a source IP address of 0.0.0.0, the device sends a MAC authentication request without including the IP address. In this case, the IMC server does not examine the user IP address when it performs authentication.

Upon receipt of the authentication request that includes a user's IP address, the IMC server compares the user's IP and MAC addresses with its IP-MAC mappings.

·          If an exact match is found or if no match is found, the user passes MAC authentication. In the latter case, the server creates an IP-MAC mapping for the user.

·          If a mapping is found for the MAC address but the IP addresses do not match, the user fails the MAC authentication.

Do not use this command in conjunction with the mac-authentication guest-vlan command on a port. If both commands are used, the device cannot perform MAC authentication for a user once that user is added to the MAC authentication guest VLAN.

Examples

# Include user IP addresses in MAC authentication requests on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

mac-authentication critical vlan

Use mac-authentication critical vlan to configure a MAC authentication critical VLAN on a port.

Use undo mac-authentication critical vlan to restore the default.

Syntax

mac-authentication critical vlan critical-vlan-id

undo mac-authentication critical vlan

Default

No MAC authentication critical VLAN exists on a port.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Parameters

critical-vlan-id: Specifies a VLAN as the MAC authentication critical VLAN. The value range for the VLAN ID is 1 to 4094. Make sure the VLAN has been created.

Usage guidelines

The MAC authentication critical VLAN accommodates users that have failed MAC authentication because all the servers in their ISP domains are unreachable. Users in the critical VLAN can access network resources in the critical VLAN.

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

The critical VLAN feature takes effect when MAC authentication is performed only through RADIUS servers. If a MAC authentication user fails local authentication after RADIUS authentication, the user is not assigned to the critical VLAN.

Before you delete a VLAN that has been set as a MAC authentication critical VLAN, use the undo mac-authentication critical vlan command to remove the critical VLAN configuration.

Examples

# Configure VLAN 100 as the MAC authentication critical VLAN on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

Usage guidelines

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

Before you enable the MAC authentication 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.

Examples

# Enable the MAC authentication critical voice VLAN feature on GigabitEthernet 1/0/1.

Parameters

domain-name: Specifies the name of an ISP domain, a case-insensitive string of 1 to 255 characters.

Usage guidelines

The global authentication domain applies to all MAC authentication-enabled ports. An authentication domain specified in Layer 2 Ethernet interface view applies only to the port. You can specify different authentication domains on different ports.

A port chooses an authentication domain for MAC authentication users in the following order:

1.        Authentication domain specified on the port.

2.        Global authentication domain specified in system view.

3.        Default authentication domain.

Examples

# Specify ISP domain domain1 as the global MAC authentication domain.

<Sysname> system-view

[Sysname] mac-authentication domain domain1

# Specify ISP domain aabbcc as the MAC authentication domain on GigabitEthernet 1/0/1.

Syntax

mac-authentication host-mode multi-vlan

undo mac-authentication host-mode

Default

MAC authentication multi-VLAN mode is disabled on a port. When the port receives a packet sourced from an authenticated MAC address in a VLAN not matching the existing MAC-VLAN mapping, the device logs off and reauthenticates the user.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

The MAC authentication multi-VLAN mode prevents an authenticated online user from service interruption caused by VLAN changes on a port. When the port receives a packet sourced from the user in a VLAN not matching the existing MAC-VLAN mapping, the device neither logs off the user nor reauthenticates the user. The device creates a new MAC-VLAN mapping for the user, and traffic transmission is not interrupted. The original MAC-VLAN mapping for the user remains on the device until it dynamically ages out. As a best practice, configure this feature on hybrid or trunk ports.

This feature improves transmission of data that is vulnerable to delay and interference. It is typically applicable to IP phone users.

Examples

# Enable MAC authentication multi-VLAN mode on GigabitEthernet 1/0/1.

Parameters

max-number: Specifies the maximum number of concurrent MAC authentication users on the port. The value range for this argument is 1 to 4294967295.

Usage guidelines

Set the maximum number of concurrent MAC authentication users on a port to prevent the system resources from being overused. When the maximum number is reached, the port denies subsequent MAC authentication users.

Examples

# Configure GigabitEthernet 1/0/1 to support a maximum of 32 concurrent MAC authentication users.

Usage guidelines

This command allows the device to log off a user if the device does not receive any packets from that user within an offline detect interval. In addition, the device requests the accounting server to stop accounting for that user. To set the offline detect timer, use the mac-authentication timer command.

The undo mac-authentication offline-detect enable command disables the device from inspecting the online user status.

Examples

# Disable MAC authentication offline detection on GigabitEthernet 1/0/1.

Usage guidelines

When you configure this command on a port, follow these restrictions and guidelines:

·          Make sure the port meets the following requirements:

¡  The port is configured with both 802.1X authentication and MAC authentication and performs MAC-based access control for 802.1X authentication.

¡  The port is enabled with the 802.1X unicast trigger.

·          For the port to perform MAC authentication before it is assigned to the 802.1X guest VLAN, use the dot1x guest-vlan-delay new-mac command to delay assigning the port to the 802.1X guest VLAN.

·          Do not enable MAC authentication delay on the port. This operation will delay MAC authentication after 802.1X authentication is triggered.

·          To configure both 802.1X authentication and MAC authentication on the port, use one of the following methods:

¡  Enable the 802.1X and MAC authentication features separately on the port.

¡  Enable port security on the port. The port security mode must be userlogin-secure-or-mac or userlogin-secure-or-mac-ext.

For information about port security mode configuration, see port security in Security Configuration Guide.

Usage guidelines

Periodic MAC reauthentication enables the access device to periodically authenticate online MAC authentication users on a port. This feature tracks the connection status of online users and updates the authorization attributes assigned by the server, such as the ACL and VLAN.

To set the periodic reauthentication timer, use the mac-authentication timer reauth-period command in system view or in Ethernet interface view.

Examples

# Enable the periodic MAC reauthentication feature on GigabitEthernet 1/0/1 and set the global periodic reauthentication timer to 1800 seconds.

<Sysname> system-view

[Sysname] mac-authentication timer reauth-period 1800

Parameters

auth-delay auth-delay-time: Sets the delay time for MAC authentication in seconds. The value range is 1 to 180.

reauth-period reauth-period-value: Sets the port-specific periodic MAC reauthentication timer in seconds. The value range is 60 to 7200.

Usage guidelines

When both 802.1X authentication and MAC authentication are enabled on a port, you can delay MAC authentication so that 802.1X authentication is preferentially triggered. If no 802.1X authentication is triggered or if 802.1X authentication fails within the delay period, the port continues to process MAC authentication.

Do not set the port security mode to mac-else-userlogin-secure or mac-else-userlogin-secure-ext when you want to use MAC authentication delay. The delay does not take effect on a port in either of the two modes. For more information about port security modes, see "Port security commands."

The device reauthenticates online MAC authentication users on a port at the specified periodic reauthentication interval if the port is enabled with periodic MAC reauthentication. To enable periodic MAC reauthentication on a port, use the mac-authentication re-authenticate command.

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

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

1.        Server-assigned reauthentication timer.

2.        Port-specific reauthentication timer.

3.        Global reauthentication timer.

4.        Default reauthentication timer.

Examples

# Enable MAC authentication delay on GigabitEthernet 1/0/1 and set the delay time to 10 seconds.

Parameters

offline-detect offline-detect-value: Sets the offline detect timer in seconds, in the range of 60 to 2147483647.

quiet quiet-value: Sets the quiet timer in seconds, in the range of 1 to 3600.

reauth-period reauth-period-value: Sets the global periodic MAC reauthentication timer in seconds, in the range of 60 to 7200.

server-timeout server-timeout-value: Sets the server timeout timer in seconds, in the range of 100 to 300.

Usage guidelines

MAC authentication uses the following timers:

·          Offline detect timer—Sets the interval that the device waits 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 MAC authentication offline detection feature is enabled.

As a best practice, set the MAC address aging timer to the same value as the offline detect timer. This operation prevents a MAC authenticated user from being logged off within the offline detect interval because of MAC address entry expiration.

·          Quiet timer—Sets the interval that the device must wait before the device can perform MAC authentication for a user that has failed MAC authentication. All packets from the MAC address are dropped during the quiet time. This quiet mechanism prevents repeated authentication from affecting system performance.

·          Periodic MAC reauthentication timer—Sets the interval at which the device reauthenticates online MAC authentication users on a port if the port is enabled with periodic MAC reauthentication. A change to the global periodic reauthentication timer applies to online users only after the old timer expires.

·          Server timeout timer—Sets the interval that the device waits for a response from a RADIUS server before the device determines that the RADIUS server is unavailable. If the timer expires during MAC authentication, MAC authentication fails.

To avoid forced logoffs 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 in Security Configuration Guide.

# Set the server timeout timer to 150 seconds.

Parameters

fixed: Uses a shared account for all MAC authentication users.

account name: Specifies the username for the shared account. The name is a case-sensitive string of 1 to 55 characters, excluding the at sign (@). If you do not specify a username, the default name mac applies.

password: Specifies the password for the shared user account.

cipher: Specifies a password in encrypted form.

simple: Specifies a password in plaintext form. For security purposes, the password specified in plaintext form will be stored in encrypted form.

string: Specifies the password. Its plaintext form is a case-sensitive string of 1 to 63 characters. Its encrypted form is a case-sensitive string of 1 to 117 characters.

mac-address: Uses MAC-based user accounts for MAC authentication users. You can also specify the format of username and password by using the following keywords:

·          with-hyphen: Includes hyphens in the MAC address, for example xx-xx-xx-xx-xx-xx.

·          without-hyphen: Excludes hyphens from the MAC address, for example, xxxxxxxxxxxx.

·          lowercase: Enters letters in lower case.

·          uppercase: Enters letters in upper case.

Usage guidelines

If you specify the MAC-based user account, the device uses the MAC address of a user as the username and password for MAC authentication of the user. This user account type ensures high authentication security. However, you must create on the authentication server a user account for each user, using the MAC address of the user as both the username and password.

If you specify a shared user account, the device uses the specified username and password for MAC authentication of all users. Because all MAC authentication users use a single account for authentication, you only need to create one account on the authentication server. This user account type is suitable for trusted networks.

Examples

# Configure a shared account for MAC authentication users, and set the username to abc and password to plaintext string of xyz.

<Sysname> system-view

[Sysname] mac-authentication user-name-format fixed account abc password simple xyz

# Use MAC-based user accounts for MAC authentication users. Each MAC address must be in the hexadecimal notation with hyphens, and letters are in upper case.
