Issue Description

We are experiencing the alarm : CONFIGURATION RESTORATION FAILURE ALARM on two of our devices on the network.

As per the instructions, I’ve ran the following recommended command, but I don’t understand the output.

The current startup saved-configuration file is cfcard:/cor2.lond1.0222_2.cfg.

The number of failed commands is 16.

transparent.gif Handling Process

When we checked the configuration, we noticed that undo dcn command have been executed globally under system view and this is why undo dcn vlan mode under interface view is not working.

Probably those commands undo dcn vlan mode were in cfcard:/cor2.lond1.0222_2.cfg and this is why he got the alarm.


transparent.gif Root Cause

In the diagnostic file I have seen that the dcn function it is disabled globally with the undo dcn command in the system view. DCN needs to be enabled globally and on interfaces when the network management system (NMS) manages devices using DCN. 

Customer was using DCN function. When he decided that he don’t want to use it he disable it globally. After an equipment reboot, when the configuration was loading, equipment try to configure the undo dcn vlan mode because this commands appears in the Cfcard:/xxx.cfg on the interface level but the error Failed to execute the command pops up because the dcn function is disable globally.

To solve this situation customer needs to clear the alarms and save the configuration.

# Clear all active alarms in the system.
