ExtremeWare Enterprise Manager uses DLCS information to create a policy object for a
user or end station that is mapped to the appropriate physical attributes (IP address and
switch, port).

For DLCS to operate within the ExtremeWare Enterprise Manager Policy System, two
conditions must be met:
• DLCS must be enabled on the switch.
• In the Policy System client, the user or end station must be set to allow automatic
DLCS updates.
If both of these conditions are true, then the policy system will expect to get current
physical attributes for the user or end station dynamically through DLCS. If auto
configuration is enabled in the Policy System client, then dynamic data learned through
DLCS will also update the configured policies.

ROPERTIES
The following guidelines must be used when using DLCS:
• Only one user can be attached to an end station (host) at a given time. This will be
the last user that logged in.
• A user may be logged into many end stations simultaneously.
• An IP address can be learned on only one port in the network at a given time.
• Multiple IP addresses can be learned on the same port.
• DLCS mapping is flushed when a user logs in or logs out or when an end station is
shut down.

DLCS must be enabled on the switch in order for Enterprise Manager to make use of
the capability. It cannot be enabled directly from the Enterprise Manager, it must be
enabled using the ExtremeWare CLI through Telnet. Thus, DLCS is not an option under
