What this is? Pretty simple…Juniper started off automating stuff via SLAX, something that did not get too much traction and then Python took the lead in front of it. It is an XML/Xpath based language and for simple things you can find it pretty useful and not so complicated to learn. What the script below does is effectively enabling a MIC upon its insertion into an MX5. Previously someone from operations would have to go manually on the device and enable it.
