Local MAC authentication configuration example

As shown in Figure 48, the device performs local MAC authentication on GigabitEthernet 1/0/1 to control Internet access of users.

Configure the device to meet the following requirements:

• Detect whether a user has gone offline every 180 seconds.

• Deny a user for 180 seconds if the user fails MAC authentication.

• Authenticate all users in ISP domain bbb.

• Use the MAC address of each user as the username and password for authentication. A MAC address is in the hexadecimal notation with hyphens, and letters are in lower case.

# Add a network access local user. In this example, configure both the username and password as Host A's MAC address 00-e0-fc-12-34-56.

The output shows that Host A has passed MAC authentication and has come online. Host B failed MAC authentication and its MAC address is marked as a silent MAC address.
