Chapter 13 Managing the SCMP
About SCMP
The loss-of-sync timeout prevents the Cisco SCE platform from retaining sessions that are obsolete and
whose identity-keys have been replaced or moved to other sessions thus miss-classification risk is
limited.
SCMP Subscriber Management
Subscriber virtualization allows multiple SCMP peer devices to simultaneously manage subscribers in
the Cisco SCE platform without interfering with each other. (Note that each device must handle a distinct
set of subscribers and network IDs.)
The following mechanisms support subscriber virtualization:
•
SCMP adds the Manager-Id field to each subscriber record in the database.
•
All SCMP subscriber provisioning operations include the Manager-Id parameter for each subscriber.
•
SCMP performs synchronizations in the context of the Manager-Id.
•
SCMP dispatches queries according to the configuration of the anonymous subscriber groups.
GUID and Subscriber ID
The SCMP requires the use of a globally unique identifier (GUID) that is created by and identifies each
SCMP peer device. The GUID is a 16-character-long ASCII string. The Cisco SCE platform uses the
GUID for all communication with the SCMP peer.
SCMP creates the Cisco SCE subscriber ID from the concatenation of any or all the following
user-related RADIUS attributes, with the GUID as the suffix.
•
Calling-Station-Id
•
NAS-port-Id
•
User-Name
The user defines this subscriber ID structure via CLI.
