When I add an SA to a VPN that is monitored, why isn't this SA monitored in this VPN monitor
automatically?
The system does not add a new SA to any monitor automatically, and you need to do it yourself. When
you delete an SA, the system removes it from all the monitors.
Why can't SA be monitored after rebooting a Cisco device?
The interface index is changed after reboot. To prevent this situation, execute the snmp-server ifindex
persist command in Cisco devices.
When I add a VPN or SA to monitor, why does it return "Interface traffic sampling test failed"
or doesn't display a correct status?
• Check the GET operation on ifTable (ifXTable) through SNMP protocol.
• Try to synchronize PEs in the VPN or SA first, make auto discovery, and then add it to monitor again.
When I import devices to MPLS VPN Management, why can't I see Cisco devices in the Select
Device page?
The MPLS VPN Management has no Cisco driver. Contact the technical support center.
Why is the progress information in the device import operation result page incorrect
sometimes?
Only one client can perform the device import operation at a time. If two clients perform the operation
at almost the same time, they may be able to perform the operation but the progress information cannot
show the device import progress correctly. However, the device import operations succeed. In this case,
you can view the operation results from the device list.
When several spokes are deployed, why can't these links be discovered?
When the networking scheme is Hub-Spoke, it is necessary to configure both hub and spoke nodes in
order to discover valid links.
What should be done if MPLS VPN Management daemon process terminates abnormally, for
instance, when power goes off, and MPLS VPN Management may not be working properly?
Delete all VPNs and PEs in MPLS VPN Management. Import PE again and execute auto discovery.
Why is the audit result of CE-to-CE "unconnective" when CE-to-CE is actually "connective"?
MPLS VPN Management executes connectivity audit when it receives related alarms. Because of a time
delay, such as device reboot or instantaneous power down and up, BGP is not steady. In this case audit
result may not be correct. If this happens, audit VPN manually.
Why can't MPLS VPN Management discover hierarchy relation in an existing VPN?
MPLS VPN Management cannot discover UPEs in an existing VPN if there are new UPEs added into the
VPN network. In this case delete all PEs and execute auto discovery again.
