How to interpret the Delta Config Summary output?



Article ID: KB9847 KB Last Updated: 05 Jul 2010Version: 5.0
The Delta Config Summary output consist of 3 sections which allows the administrator to determine what is currently configured on the device, what is currently configured in NSM and what commands would be sent to the device in order to make the device consistent with NSM.
Symptoms & Errors:
  • Delta Config contains Unset and Set commands
  • How to confirm "Currently on device" is correct
The Delta Config Summary allows the administrator to determine:
  • What is currently configured on the device
  • What is currently configured in NSM
  • What commands would be sent to the device in order to make the device consistent with NSM.

Typical the commands to be sent to the device can include  “unset” followed by “set” commands for the same policy.    This usually means that the policy has to be recreated in order to correct it.    The same can apply for VPN configurations.  If some settings have changed, it is possible that NSM tries to unset then set the VPN to reconfigure the parameters.

If the output from the section “currently on the device” does not seem accurate, compare this information to the output from the WebUI or CLI command “get config” .  Confirm the corresponding parameter is set correctly.    If the WebUI and CLI show the setting is correct but NSM still reports the device has a different value, the problem is most likely a result of the  XML style configuration provided to NSM by the device.  To confirm, use the ScreenOS command:  “get config datafile”.      This will confirm whether the value reported by the device is incorrect.  If it is,  contact JTAC; consult KB9846 - What information do I need to Collect before Opening an NSM case?
