Python automation with PyEZ. Part 2.
The idea for this post came to my mind during the discussion I had with one of the customer engineers staff, regarding new security features that they want to implement. During the conversation, one of the engineers complained that he spends too much time adding address objects to their security appliances. Basically he receives some…
OAM Boot Menu on Juniper Networks EX Series.
Have you ever wondered what all of the options in „OAM Boot Menu” on ex2300 and ex3400 are for? Since it’s rather poorly documented in Juniper’s docs, I decided to explain all of the available options, as well as to give some insight into what all of those options do.
