Just went through a major server move for a client - looks like everything went well except only a very small subset of their network is up. I've got an EX4200 with 3 VC members acting more-or-less as the core switch (someone else set this up before me).
Every light with a link is blinking on both link and actviity (and all in sync). My first though was broadcast storm, but WireShark only shows some mid-range arp traffic and nothing else.
Is there a way to verify this is a broadcast storm on the EX4200 (STP is enabled, so that shouldn't happen...)
I've been doing lots of troubleshooting the past few hours; it appears that somehow the aggreated Cat5-3 link between my SRX and Edge-level EX4200 was broken during the move (they both experienced some downtime). I confirmed this using the command and output in reply to thynard's response. It's unclear to me right now where the problem is, but I was able to verify that everything is still as it should be on the SRX, so are the any reccommendations as to how to connect to my now-comatose switch and restore its functionality?
it's worth adding there are some service which flow through the EX but do not involve the SRX which I have confirmed up and working, so it's definitely the aggregation that broke this (which sucks, because the only stuff there is stuff users won't care about).
