Model: ex4300-48pJUNOS EX Software Suite [13.2X51-D35.3].
I have a juniper 4300 stack that we use for our core routing which has been leaving me a little stumped as to what might be happening on it network wise. Reading up on mac moves it is sounding like with the number of them we are having it could be a possible network loop. Our clients are experiencing slow and intermittnet network connectivity. What I am wondering is if I am even on the right track with focusing so much on the mac move log messages on the core or if I should be looking elsewhere. Below is a chunk of log messages from the core . Any input on the matter would be greatly appreciated our school is loosing patience with me. If there are anymore details you would request for show commands or additional logs let me know happy to provide!
