Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Parameters

ignore-config: Specifies the ignore-config mode to ignore the static VLAN assignment configuration for a port. In ignore-config mode, whether the port is assigned to the authorization VLAN as a tagged member is determined only by the authorization VLAN auto-tag feature.

Usage guidelines

This command takes effect only on hybrid ports that are enabled with MAC-based VLAN.

The port's tagging status configuration in the authorization VLAN by this command takes precedence over the AAA server's configuration of the port's tagging status in the authorization VLAN. However, when the authorization VLAN is the port VLAN, this command does not take effect.

When the ignore-config mode is disabled, the tagging status of the port in the authorization VLAN is determined by the static VLAN assignment configuration for the port. For information about the static VLAN assignment configuration for a port, see the port hybrid vlan vlan-list { tagged | untagged command in Layer 2–LAN Switching Command Reference.

When a port is enabled with the authorization VLAN auto-tag feature, do not use the undo vlan command to delete the authorization VLANs authorized to authenticated users.

When you configure this command on a port, make sure the port does not have online users. This command will not take effect if there are online users.

Examples

# Enable the authorization VLAN auto-tag feature on GigabitEthernet 1/0/1.

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 who fail 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.

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.

Default

MAC authentication offline detection is enabled on a port.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

Usage guidelines

The MAC authentication offline detection feature monitors the online status of MAC authentication 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 set the offline detect timer, use the mac-authentication timer command.

Examples

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

Predefined user roles

network-admin

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.

For information about the dot1x guest-vlan-delay new-mac command, see "802.1X commands."

· 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.

Parameters

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

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

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

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

Usage guidelines

MAC authentication uses the following timers:

· Offline detect timer—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 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 who 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, the user cannot access the network.

Examples

# Set the server timeout timer to 150 seconds.

mac-authentication timer (interface view)

Use mac-authentication timer to configure a MAC authentication timer on a port.

Use undo mac-authentication timer to restore the default of a MAC authentication timer.

Syntax

mac-authentication timer { auth-delay auth-delay-time | reauth-period reauth-period-value }

undo mac-authentication timer { auth-delay | reauth-period }

Default

No MAC authentication delay timer is set on a port. MAC authentication delay is disabled. MAC authentication starts immediately after it is triggered by a user packet.

No periodic MAC reauthentication timer is set on a port. The port uses the global periodic MAC reauthentication timer.

Parameters

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

reauth-period reauth-period-value: Specifies 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.

mac-authentication user-name-format

Use mac-authentication user-name-format to configure the type of user accounts for MAC authentication users.

Use undo mac-authentication user-name-format to restore the default.

Syntax

mac-authentication user-name-format { fixed [ account name ] | mac-address [ { with-hyphen | without-hyphen } [ lowercase | uppercase ] ] } [ password { cipher | simple } string ]

undo mac-authentication user-name-format

Default

The MAC address of each user is used as the username and password for MAC authentication. The MAC addresses are in hexadecimal notation without hyphens, and letters are in lower case.

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.

mac-address: Uses MAC-based user accounts for MAC authentication users.

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

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

lowercase: Specifies letters in lower case.

uppercase: Specifies letters in upper case.

password: Specifies the user password. If you do not specify a password for MAC-based user accounts, the device uses the MAC address of each user in the specified format as the password. If you do not specify a password for the shared account, the shared account does not have a password.

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.

Usage guidelines

If you specify the MAC-based user account format, the device uses the MAC address of a user as the username 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 the username.

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 the MAC address of each user as both the username and password for MAC authentication. The MAC addresses are in hexadecimal notation with hyphens, and letters are in upper case.

Parameters

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

mac mac-address: Specifies a MAC authentication user by its MAC address. The mac-address argument is in the format of H-H-H.

username username: Specifies a MAC authentication 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.

Usage guidelines

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

With a VLAN specified, this command logs off the following MAC authentication users:

· Users that have passed MAC authentication and have been assigned the specified VLAN as their authorization VLAN by the server.

· Users that stay in the specified VLAN after they have passed MAC authentication, because they have not been assigned an authorization VLAN yet.

· Users that are performing MAC authentication in the specified VLAN.

To identify the VLAN in which a user is staying, use the display mac-address command.

If you do not specify any parameters, the reset mac-authentication access-user command logs off all MAC authentication users on the device.
