[ScreenOS] How do I synchronize configurations for NSRP?



Article ID: KB6351 KB Last Updated: 22 Sep 2020Version: 13.0

This article explains how to synchronize configurations for NetScreen Redundancy Protocol (NSRP)?

  • How do I check if the configurations are synchronized for NSRP?

  • If the output of the exec nsrp sync global-config check-sum reports configuration out of sync, how do I sync the configurations?

  • FW1 is the Primary.
  • FW2 is the Backup
  • You have determined that FW1 has the correct working configuration, and you want FW2's configuration to be synchronized from FW1.

To sync the configurations, enter the following command on FW2:

nsisg2000(B)-> exec nsrp sync global save

The following will be reported shortly after you enter the above command, to see the messages you need to be logged in using a console connection:

nsisg2000(B)-> load peer system config to save
Save global configuration successfully.
Continue to save local configurations ... Save local configuration successfully.
Please reset your box to let cluster configuration take effect!

Then FW2 needs to be reset for the configuration to take effect. 

 IMPORTANT:  If you are prompted to save the configuration after you enter the reset command, answer n (No).  Then, proceed with the reboot by answering y (Yes).

nsisg2000(B)-> reset
nsisg2000(B)-> Configuration modified.  Save? [y] y/n  n
nsisg2000(B)-> System reset? Are you sure? y/n  y

When FW2 boots back up, the configurations will be in sync.

To confirm that the firewalls are in sync, refer to KB6359: How do I check if the Active/Passive NSRP pair configurations are in sync?
