Upgrading a Unit to the Advanced SLM Feature Set
Full Service Level Management (SLM) capability can be activated in units that have the
basic diagnostic feature set at any time. This is an optional feature that adds real-time
and historical network performance monitoring and SLA (Service Level Agreement)
reporting capabilities to your iMarc unit and network. Simply order a Feature Activation
Certificate and provide the model to be activated, your OpenLane®SLM system license
key number, and the number of iMarc units to be activated to SLM capability. You can
order the certificate for a single unit or for many units.
OpenLane SLM Release 5.3 or above is required to schedule activation of SLM features
in units, and to manage the number of activations remaining on the certificate.
OpenLane also provides a Certificate Summary Report to assist you in the management
of the certificate.
When the Feature Activation Certificate arrives, add the Activation Certificate Number to
your OpenLane SLM application’s database. Activations can occur at any time, for as
many units as desired, until no activations remain for the certificate. When ready to
activate units, simply select the units to be activated and schedule the activations. The
activations occur when scheduled, and OpenLane updates the certificate information.
Contact your sales representative for additional information.

4. Save the configuration.
Automatic Configuration
The iMarc unit provides several automatic configuration features. Frame Relay
Discovery and configuration is one of these features.
Main Menu → Auto-Configuration
The default discovery mode is 1MPort. In this mode, for each DLCI discovered on the
network, a multiplexed network DLCI and a standard data port DLCI will be configured
and connected, and a Management PVC will be embedded in the network DLCI.
NOTE:
When auto-configuration creates a multiplexed DLCI, but a standard DLCI is
needed, change the DLCI to Standard from the network DLCI Records screen:
Configuration → Network → DLCI Records
Other modes can be selected. See Setting Up Automatic Configuration in Configuration
of the iMarc SLV Configuration Reference (9000-A2-GB31) for information about other
