Aging Subscribers
Subscribers can be aged automatically by the SCE platform. 'Aging' is the automatic removal of a
subscriber, performed when no traffic sessions assigned to it have been detected for a certain amount of
time. The most common usage for aging is for anonymous subscribers, since this is the easiest way to
ensure that anonymous subscribers that have logged-out of the network are removed from the SCE
platform and are no longer occupying resources. Aging time can be configured individually for
introduced subscribers and for anonymous subscribers.
Introduced subscriber aging is not supported when using VPN-based subscribers.
VPN-Based Subscribers
A VPN-based subscriber contains a set of mappings of the form: IP@VpnName, where IP can be either
a single IP address or a range of addresses. A VPN-based subscriber may be either VLAN-based or
MPLS/VPN-based
Most VPN-based subscriber functionality is managed via the SM, with the role of the SCE platform CLI
being more limited.
The SCE platform CLI can be used to do the following:
•
•
•
•
•
Automatic VLAN VPNs
The SCE platform will automatically create a new VPN under the following conditions
•
•
The number is used as the VLAN mapping of the newly created VPN. VLAN mappings cannot be added
to automatic VPNs.
