Table 1-1 Description on the fields of the display mac-authentication command

Field	Description
Mac address authentication is Enabled	MAC address authentication is enabled.
Authentication mode	Username type used in the MAC address authentication: l UsernameFixed: Uses the fixed username for authentication. l UsernameAsMacAddress: Uses the MAC address of a user as the username for authentication. The default is the MAC address (UsernameAsMacAddress).
Fixed password	Meaning of this field varies by the username type for MAC address authentication: l If the username type is MAC address, this field indicates whether to use a fixed password for authentication. By default, this field is not configured, which means using the MAC address of a user as the password for authentication. l If the username type is fixed username, this field indicates whether a fixed password is configured. By default, this field is not configured, which means the password is null.
Fixed password	Password used in the fixed mode, which is not configured by default.
Offline detect period	Offline detect timer, which sets the time interval to check whether a user goes offline and defaults to 300 seconds.
Quiet period	Quiet timer sets the quiet period. A switch goes through a quiet period if a user fails to pass the MAC address authentication. The default value is 60 seconds.
Server response timeout value	Server timeout timer, which sets the timeout time for the connection between a switch and the RADIUS server. By default, it is 100 seconds.
Guest VLAN re-authenticate period	Re-authenticate timer, which sets the time interval to reauthenticate the users in the Guest VLAN and defaults to 30 seconds.
Max allowed user number	The maximum number of users supported by the switch. It is 1,024 by default.
Current user number amounts to	The current number of users
Current domain	The current domain. It is not configured by default.
Silent Mac User info	The information about the silent user. When the user fails to pass MAC address authentication because of inputting error user name and password, the switch sets the user to be in quiet state. During quiet period, the switch does not process the authentication request of this user.
Ethernet1/0/1 is link-up	The link connected to Ethernet1/0/1 port is up.
MAC address authentication is Enabled	MAC address authentication is enabled for Ethernet1/0/1 port.
max-auth-num	Maximum number of MAC address authentication users that the port can accommodate

MAC Address Authentication Enhanced Function Configuration Commands

mac-authentication guest-vlan

Syntax

mac-authentication guest-vlan vlan-id

undo mac-authentication guest-vlan

View

Ethernet port view

Parameters

vlan-id: ID of the guest VLAN configured for the current port. This argument is in the range of 1 to 4,094.

Description

Use the mac-authentication guest-vlan command to configure a guest VLAN for the current port. If the client connected to the port fails in the authentication, the port will be added to the guest VLAN, and thus the users accessing the port can access network resources in the guest VLAN.

Use the undo mac-authentication guest-vlan command to remove the guest VLAN configuration for the port.

No guest VLAN is configured for a port by default.

The system will re-authenticate users in the guest VLAN at the interval configured by the mac-authentication timer guest-vlan-reauth command. If the user of a port passes the authentication, the port will leave the guest VLAN and return to the initial VLAN configured for it.

l If more than one client are connected to a port, you cannot configure a Guest VLAN for this port.

l When a Guest VLAN is configured for a port, only one MAC address authentication user can access the port. Even if you set the limit on the number of MAC address authentication users to more than one, the configuration does not take effect.

l The undo vlan command cannot be used to remove the VLAN configured as a Guest VLAN. If you want to remove this VLAN, you must remove the Guest VLAN configuration for it. Refer to the VLAN module in this manual for the description on the undo vlan command.

l Only one Guest VLAN can be configured for a port, and the VLAN configured as the Guest VLAN must be an existing VLAN. Otherwise, the Guest VLAN configuration does not take effect. If you want to change the Guest VLAN for a port, you must remove the current Guest VLAN and then configure a new Guest VLAN for this port.

l 802.1x authentication cannot be enabled for a port configured with a Guest VLAN.

l The Guest VLAN function for MAC address authentication does not take effect when port security is enabled.

Related commands: mac-authentication timer guest-vlan-reauth.

Parameter

None

Description

Use the mac-authenticiaon intrusion-mode block-mac enable command to enable the quiet MAC function on a port. When this function is enabled, the MAC address connected to this port will be set as a quiet MAC address if its authentication fails. When this function is disabled, the MAC address will not become quiet no matter whether the authentication is failed.

Use the undo mac-authenticiaon intrusion-mode block-mac enable command to disable the quiet MAC function on a port.

By default, quiet MAC function is enabled on a port.

Example

# Enable the quiet MAC function on port Ethernet 1/0/1.

undo mac-authentication max-auth-num

View

Ethernet port view

Parameters

user-name: Maximum number of MAC address authentication users allowed to access a port. This argument is in the range of 1 to 256.

Description

Use the mac-authentication max-auth-num command to configure the maximum number of MAC address authentication users allowed to access the port. After the number of access users has exceeded the configured maximum number, the switch will not trigger MAC address authentication for subsequent access users, and thus these subsequent access users cannot access the network normally.

Use the undo mac-authentication max-auth-num command to restore the maximum number of MAC address authentication users allowed to access the port to the default value.

By default, the maximum number of MAC address authentication users allowed to access a port is 256.

l If both the limit on the number of MAC address authentication users and the limit on the number of users configured in the port security function are configured for a port at the same time, the smaller value of the two configured limits is adopted as the maximum number of MAC address authentication users allowed to access this port. Refer to the Port Security module in this manual for the description on the port security function.

l You cannot configure the maximum number of MAC address authentication users for a port if any user connected to this port is online.

Examples

# Set the maximum number of MAC address authentication users allowed to access Ethernet 1/0/2 to 100.
