All of a sudden things may start go wrong in your juniper switches and when you examine the logs you see the followings;
I am currently deploying a Viptela vEdge 17.2.x series in my ESX lab however as soon as I fired up multiple vEdges I noticed CPU utilisation went through the roof. Server couldn’t handle 4-5 instances as each consumes around 8GHz. This was very familiar to me from virtual SRX experience due to continuous polling and

Here is a quick one which allowed me to query an EX switch through its VR (in my example VR name is ISP1). You can also specify your specific VR name under “routing-instance-access”

Have you ever wanted to list the trunk ports on a Juniper EX switch? Unfortunately there doesn’t seem to exist a single dedicated command for this purpose. In the past I used to use the following command: > show ethernet-switching interfaces detail | match Trunk but this is not working on new releases. Juniper keeps
