In the process of configuring traffic forwarding, IGP shortcut or forwarding adjacency
configuration is successful, but why isn't there a related record in the IMC database?
The MPLS TE management can obtain only the configuration currently used by the device. However, the
device may not be using the traffic forwarding configuration that you made. Therefore, there is no record
of your configuration in the IMC database.
When configuring multiple protections for the same interface, why does the TE management
only show information for one protection?
Even though multiple protections are configured, only one protection can be active when tunnel is down.
Other protections do not take effect. The TE management only displays the ones that are active.
MPLS Management
Why does the system prompt "Telnet failure" when I import a device?
Analysis: The Telnet parameters on the IMC platform are inconsistent with those configured on the
device.
Solution: View and modify the Telnet parameters for the device on the device details page on the IMC
platform.
Why does the system prompt "synchronization failure" when I synchronize a device on the
Device Management page or in the MPLS topology?
Analysis: Possible reasons for the synchronization failure include device unreachability, inconsistency of
Telnet parameters on the IMC platform and those on the device, and device model not being supported
by the MPLS management.
Solution: Check and modify the network configuration if needed to make sure the device and IMC can
reach each other. View and modify Telnet parameters on the device details page of the IMC platform.
See the Release Notes to check whether MPLS Management supports the device model.
