Minimum Age
to Purge
Age (in days) at which configurations should be purged (between 5-360).
Configuration Change Purge Settings
Purge Change Logs
after
The age in days at which configuration change notifications (Change Logs) that are sent by devices
should be purged. The default is 30 days and the range is 5-360.
Global Settings
Transport Protocol Default transport protocol that Prime Network should use when copying configuration files to and
from a device. The options are TFTP, SFTP/SCP, and FTP. The default is TFTP. Note the following:
• The TFTP source interface on the devices must be able to reach the unit. Otherwise, the
configuration management jobs that require TFTP may fail.
• To use SFTP/SCP for config transfers from a device to a unit, you need to ensure that an SSH
server is configured and running on the device, such that the device acts as a server and the unit
as a client during the transfer. For Cisco IOS XR devices, you need to configure the device with
K9 security (k9sec) enabled images such that the SSH server is up and running on the device.
Enable Periodic
Config Backup
Detect ongoing configuration changes by performing a periodic collection of device information. Use
this method if configurations change frequently and those changes are not important to you. CM
compares the timestamp for the last configuration change on the archived version with the timestamp
on the newer version. If they are different, CM backs the new file to the archive immediately. By
default, this is not enabled.
You can set up an interval in the range of 1-100 hours. Default value is 72 hours.
Note This CM collection is independent of the Prime Network inventory collection.
Enable Periodic Sync
for Out of Sync
Devices (72 Hours)
(For Cisco IOS only) Enables automatic synchronization of the out-of-sync devices on a periodic
basis. Prime Network adds a device to the list of out-of-sync devices whenever the latest version of
the startup configuration is not in sync with the latest version of the running configuration file on the
device.
Periodic Export Options
Enable Periodic
Config Export
Allows CM to export archived configurations periodically to the export server. You can set up an
interval in the range of 1-100 hours to export the archived configurations. The default value for export
interval is 24 hours. You can also specify the start time for the periodic export operation.
If there are no configuration changes i.e. if the archived configuration is available in the export server,
choose one of the following options to indicate how the export job should be performed:
• Export configuration file will all configuration—Overwrite the existing configuration on the
export server.
• Do not export configuration file—Skip configuration export.
• Export configuration file with reference to previous configuration file—Create a configuration
file with only a reference to the file having the actual configuration.
Refer to Configuration Export File Type for Device Families, page 4-66, to know more about the type
of configuration files exported for different devices.
