Configuring MAC-

based VLAN

Auto-configuration

Policy

ATMvLAN application to recognize and communicate with an NT based stand-alone VLAN Server (IP address and SNMP community string).

This section describes how to configure devices to enforce the MAC-based policy.

When a device is configured for the MAC-based policy, it automatically partitions its ports into VLANs, based on the MAC address of the endstation that is attached to its ports. When an endstation attaches to a device, it automatically configures the endstation’s port to the correct VLAN based on the endstation’s MAC address. The device queries the VLAN Server to determine the correct VLAN associated with the endstation MAC address.

Under Auto-configuration mode, only one endstation is allowed to be connected to a device port.

The following steps describe the configuration of MAC based Policy on devices:

1Define two aliases; “unknown” and “default” using the ATM and VLAN Aliases and Colors Configuration Tool. See “Configuring VLAN Aliases and Colors” on page 4-21.

2Populate the Integrated VLAN Server database with MAC address to VLAN mapping information. See “Populate the Integrated VLAN Server database with MAC address to VLAN mapping information using Build UDB” on page 4-27

3Apply the MAC-based VLAN auto-configuration to the devices. See “Apply the MAC-based VLAN Auto-configuration to the Devices” on page 4-31.

4Verify that automatic VLAN auto-configuration is activated.

Populate the Integrated VLAN Server database with MAC address to VLAN mapping information using Build UDB

1Connect a PC to any port on an edge device.

2Generate some traffic from this PC so that its MAC address is learned by the device.

3Select the Users icon (from the ATMvLAN Toolbar).
