Possible to Compare and Diff configuration by ucs files

Hi,  I have some configuration change on LTM, and do the ucs backup before and after also. But I don't hope to compare those ucs files to find the different by download those archives and open anoth...

    Hello Alvin Ng,

    There are another methods to compare configs, but they are more rudimentary.

    1. Compare SCF files using TMSH

    # Extract intial config
    tmsh save sys config file /shared/tmp/initial_config.scf no-passphrase
    # Extract final config
    tmsh save sys config file /shared/tmp/final_config.scf no-passphrase
    # Compare both files
    tmsh show sys config-diff /shared/tmp/initial_config.scf /shared/tmp/final_config.scf | egrep -e "\s{3}\|\s{3}" -e "[<]$" -e "^\s*[>]"

    2. Similar to the previous command, you can use diff to compare both bigip.conf files

    # First, extract the bigip.conf file from both UCS
    # Compare both files
    diff /shared/tmp/initial_bigip.conf /shared/tmp/final_bigip.conf | egrep -e "\s{3}\|\s{3}" -e "[<]$" -e "^\s*[>]"

    3. You can also use Notepad++ to compare them, from my experience, better compare feature than diff.

    Hope this helps.
