mdc-admin

Usage guidelines

This command solves the IP conflict problem which might be caused by users' IP address modification. After you configure this command, users cannot pass MAC authentication if the IP and MAC information in the authentication requests do not match the users' IP-MAC mappings on the IMC server.

The IMC server selects the IP-MAC combination for a MAC authentication user to match in the following order:

1. The IP and MAC addresses in the IMC platform user account associated with the MAC authentication user.

2. The IP and MAC addresses that are included in the authentication request. If the server does not have an authenticated IP-MAC record for the user, it determines that the IP-MAC combination of the user is valid. The server will record the IP-MAC combination of the user. If the user IP address is changed at the next authentication, the user cannot pass authentication.

This command takes effect only on MAC authentication users who use static IP addresses. Users who obtain IP addresses through DHCP are not affected.

Do not configure this command together with the mac-authentication guest-vlan command on a port. If both commands are configured, users in the MAC authentication guest VLAN cannot perform a new round of authentication.

Examples

# Include user IP addresses in MAC authentication requests on Ten-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.

Examples

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

Views

Ethernet interface view

Predefined user roles

network-admin

mdc-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 Ten-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.

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 waits for traffic from a user before the device regards the user idle. When the offline detection feature is enabled, the device logs off the user and requests to stop accounting for the user after the timer expires.

After you set the offline detect timer, assign the same value to the MAC address aging timer by using the mac-address timer command. This operation prevents a MAC authenticated user from being offline within the offline detect timer due to 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 regards the RADIUS server unavailable. If the timer expires during MAC authentication, the user cannot access the network.

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 Ten-GigabitEthernet 1/0/1 and set the delay time to 10 seconds.

<Sysname> system-view

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

[Sysname-Ten-GigabitEthernet1/0/1] mac-authentication timer auth-delay 10

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 ] [ password { cipher | simple } string ] | mac-address [ { with-hyphen | without-hyphen } [ lowercase | uppercase ] ] }

undo mac-authentication user-name-format

Default

Each user's MAC address is used as the username and password for MAC authentication. A MAC address is in the 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.

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.
