Has anyone had this happen before? We are still gathering data but basically we had some people onsite doing a port scan of the network, and when they hit the PBX ports they caused mutiple switches to Ini



 
Forgot to mention 1 option 81c and 5 option 11c's were involved
 
Hi,

If the switch recieves to much broadcast/random ethernet traffic it dies...

Configure your routers/gateways so it only allows traffic ment for the E-LAN... And maybe from authorized IP's.

The best thing is to disconnect the M1's from the network. They should be connected to a dedicated LAN (E-LAN). But if you configure your routers correctly you should have a problem...

You will have to have the TLAN still connected to the CLAN to get to the other PBXs. Definetly remove the ELAN or create a VLAN to block broadcast messages. Broadcast WILL INI the switch.
