Hi,   I am having some challenges when implementing config templates based on device version using config-template only. My solution is aiming to use the platform version from the devices provided by the NED based on the version nr a config template is pushed.   The Version can be anything between  saos-06-11-01-0000 and saos-06-17-01-0149. The logic I am aiming to implement is when the version is above saos-06-15-00-000 then push the new config style else push the old format.   Here is an example of the version output: nsoadmin@ncs# show devices device 3916-* platform version NAME VERSION ---------------------------- 3916-A saos-06-17-01-0149 3916-B saos-06-14-00-0434   nsoadmin@ncs# show devices device 3916-* platform version | display xpath /devices/device[name='3916-A']/platform/version saos-06-17-01-0149 /devices/device[name='3916-B']/platform/version saos-06-14-00-0434 nsoadmin@ncs#   First I tried to use the following logic: <? set-root-node  {/devices/device[name=$EDU-DEVICE]/platform} ?> <? if  {/version <=   'saos-06-15 -00-0000' } ?>   I realized it was not working due to the datatype which is a string so comparison operators will not work. Also converting the check to number did not result in a valid result. <? if  { number (/version) <=   'saos-06-15 -00-0000' } ?>   I end up using the following logic:   <? set-root-node {/devices/device[name=$EDU-DEVICE]/platform} ?> <? for i =0; {$i < 15}; i ={$i +1} ?> <? if {/version = concat ( 'saos-06-' ,$i, '-00-0434' )} ?> <!--OLD style config section--> <? else ?> <!--New style config section--> <?end?> <?end?>   But the issue I have with this approach is that the for loop iterate over all nr's from 0 to 15 each time the result is false it pushes the else section and when the result is true it also pushes the if section, which ends up in both code being pushed to the device having any version between (saos-06-0-00-0434 - saos-06-15-00-0434).   The solutions can be implemented in python very easy however a requirement I have is to use XML only. Looking forward to read your feedback.   Thank you.     ... View more

Hi,   I have some question which I am struggling with, I have to read the device NED type from the device module. Almost all NEDs returns with position 0 from the keys the correct NED type except IOS-XR NED the position of the NED type is not 0 but 3 which confuses my python code:    Here is an overview of the device modules: This is what I read in Python:   def get_device_type ( root , device ):    modules = root.devices.device[device].module.keys()     return str (modules[ 0 ])   Is there a reason why IOS-XR has interfaces instead of device ned type in position 0? How do I get around this without modifying the code? ... View more
