9-3MCSICreating Dynamic VLANs Copyright © 1998, Cisco Systems, Inc. Discover user addresses and VLAN memberships Display and modify UserTracking information Configure a VLAN Membership Policy Server (VMPS) Create a VMPS database Test dynamic VLANs Objectives (cont.)

9-4MCSICreating Dynamic VLANs Copyright © 1998, Cisco Systems, Inc. UserTracking client communicates to an ANI service module Reads the CWSI database Discovers MAC addresses and VLAN assignments Creates a UserTracking database Describing the Operation of UserTracking

9-5MCSICreating Dynamic VLANs Copyright © 1998, Cisco Systems, Inc. VLAN membership policy server and clients configured on Catalyst UserTracking sends its database to a TFTP server using FTP The VMPS reads the database using TFTP Describing the Operation of VMPS

9-6MCSICreating Dynamic VLANs Copyright © 1998, Cisco Systems, Inc. VMPS dynamically assigns MAC addresses to VLANs Transfers database from the TFTP server Clients send MAC address in request VMPS sends VLAN name in response Unknown address is denied or sent to fallback VLAN Describing the Operation of Dynamic VLANs

9-7MCSICreating Dynamic VLANs Copyright © 1998, Cisco Systems, Inc. Starting UserTracking Start the application Enable ping sweeps Discover all end-user information or a single subnet Schedule periodic discovery
