SCMP Peer Devices

An SCMP peer device is a Cisco device running IOS with the ISG module enabled. The Cisco SCE
platform supports the ability to communicate with several SCMP peer devices at the same time.
However, each peer device manages its own subscribers and the corresponding subscriber network IDs.
The Cisco SCE platform recognizes which subscribers belong to which peer device. There are two
mechanisms that accomplish this:
•
•
One Cisco SCE platform supports a maximum of 20 SCMP peer devices.
Connection Management
The SCMP attempts to maintain an open connection to each peer device.

You must configure multiple Cisco SCE platforms with load-balancing (MGSCP) to work in pull
integration mode.
Login operation
Each SCMP peer device is assigned a unique ID called the Manager-Id. This ID is attached to each
subscriber from the moment it is created in the subscriber database, based on the SCMP peer that
logged-in the subscriber.
Anonymous groups
An anonymous group is a specified IP range, possibly assigned a subscriber template (see
"Anonymous Groups and Subscriber Templates" section on page
SCMP associates each SCMP peer device with at least one anonymous group. SCMP generates
subscribers for this anonymous group when it detects traffic from the SCMP peer device that is not
mapped to any subscriber. SCMP assigns the SCMP peer manager-Id to this generated
anonymous-subscriber. If you have assigned a subscriber template to the group, the anonymous
subscribers generated have properties as defined by that template. If you have not assigned a
subscriber template, the default template is used.
