Line Auto Consolidation
Cisco IOS XE software runs a nonvolatile generation (NVGEN) process to retrieve the configuration state of
the device. During the NVGEN process, the system auto consolidates the LINE commands based on common
parameters.
When the device connects to Cisco Digital Network Architecture (DNA) Center or Cisco vManage and the
center sends a line configuration through the Yet Another Next Generation (YANG) interface the resulting
configuration is auto consolidated. This can cause a mismatch between the device and the DNA Center. The
mismatch in configurations can lead to reverse sync from the device to the DNA Center. The device will be
locked from any other configuration changes during this reverse sync. This can affect the performance of the
device.
Starting with Cisco IOS XE 17.4.1 release, you can use the no line auto-consolidation command, in the
global configuration mode, to disable the auto consolidation of LINE commands. Auto consolidation is enabled
by default. To disable it use the no form of the command.
You can use the show running-configuration all command to display the configuration on the device. In the
following example line auto-consolidation is enabled.
Device#sh running-config all | i auto-consolidation
line auto-consolidation
After auto consolidation is disabled the show run command output will be lengthy. This will impact the sizes
of the running configuration and start-up configuration files. If you disable auto consolidation you will observe
the following behaviors:
• Contiguous groups of lines that belong to the same configuration in a sub-mode will not be combined
