How to Compare HA LTM VLAN & Tagging Configs

My organization has multiple LTM HA pairs.

 

Many LTMs have several VLANs configured.

 

I'm in search of a way to periodically compare the VLAN & tagging configurations of LTM HA pair devices to ensure they're in sync.

 

Thus far the only way I've found to do this is to compare the devices' bigip_base.conf files using a file comparison tool like kdiff.

 

The problem with this method is that the device bigip_base.conf file formats don't exactly match so a side-by-side comparison isn't effective. Additionally this appears to be an extremely time-consuming approach.

 

Because of the number of LTM HA pairs and number of VLAN configurations I need a more efficient way to compare the VLAN & tagging configs between LTM HA pair devices.

 

Any suggestions/recommendations will be appreciated.

    iControl would be the easiest way to do this, in my opinion.

    curl -sk -u admin:$PASS  -H "Content-Type: application/json" -X GET https://bip1/mgmt/tm/net/vlan

    Then just parse the results. Tag is included in that. The above example assumes the iControlRest, but it should be available in the older iControl as well.

    Thanks R Marc. I'll give that a try.

     

    Shortly after my initial post I found an alternate way to go about capturing the VLAN & tag information and performing a comparison. Executing a tmsh list /net vlan, copying/exporting the output to text files (which creates files with matching the formats) and comparing the two files with kdiff worked.
