Chapter 13 MPLS/VPN Support
Managing MPLS/VPN Support
MPLS/VPN MIB Objects
The mplsVpnAutoLearnGrp MIB object group (pcubeSEObjs 17) contains information regarding
MPLS/VPN auto-learning.
The objects in the mplsVpnAutoLearnGrp provide the following information:
• maximum number of mappings
• allowed current number of mappings
For more information, see the "Proprietary MIB Reference" in the Cisco Service Control Engine
Software Configuration Guide.
MPLS/VPN Traps
There is one MPLS/VPN-related trap:
• mplsVpnTotalHWMappingsThresholdExceeded (pcubeSeEvents 45)
To provide online notification of a resource deficiency, when the system reaches a level of 80%
utilization of the hardware MPLS/VPN mappings, a warning message appears in the user log, and this
SNMP trap is sent.
Both the warning and the trap are sent for each 100 mappings that are added after the threshold has been
exceeded.
Monitoring MPLS/VPN Support via SCE Platform CLI
The SCE platform CLI allows you to do the following:
• Display VPN-related mappings
• Monitor subscriber counters
• Monitor PE routers
• Monitor bypassed VPNs
Displaying VPN-related Mappings
Use the following Viewer commands to display subscriber mappings. These commands display the
following information:
• All the mappings for a specified VPN
• A listing of all currently logged-in VPNs
• A listing of all subscribers mapped to an IP range on a specified VPN
• The number of subscribers mapped to an IP range on a specified VPN
• The subscriber to whom a specified downstream mapping (PE loopback IP address and BGP label)
is mapped. (This option is provided for backwards compatibility and has certain restrictions. See
below How to Display the Name of the Subscriber Mapped to a Specified VPN, page 13-21.)
How to Display Mappings for a Specified VPN
