I am having trouble with a network and cant pinpoint the issue. The question is, IS there a way on the Mitel 3300 to look for broadcast or ip storms from a device. Nothing can be seen in the switches. Phones are in different areas and linked together via fiber. One area is randomly locking the link up (monthly). The link can be bounced and all is well for around 30 days. Is there trouble shooting that I can use from the 3300 to look for the problem. When the link is locked up it only effects the phone VLan other traffic is not affected. I am assuming something on the phone VLan is causing the issue. There IT has all the networking components (switch,DHCP and router).

Is it the phone VLAN in this one area that fails, or the entire voice VLAN (assuming it is one broadcast domain)?
I would be looking at switch logs... and no, I don't believe the 3300 can help you diagnose this. If you know it is a specific area then the switch for that area would be the logical one to be examining the logs. Usually the only way a broadcast storm can occur from a phone is if the PC port is looped back into a wall jack, but spanning tree should shutdown that port, not the VLAN at the uplink level. How many phones in this area? Can you eyeball each one and see if someone looped a cable to a wall jack or mini switch?

I have the pc ports disabled but am wondering if a tagged port from the switch has had something like that plugged into it somewhere. The IT is going to try separating out a separate vlan.
