I have a Netgear GSM7312 and everytime I plug a Netgear JGS524 into a port the GSM switch stops working. I have three of these switches and it happens on all. Done all the basic checks so far...
I can see this error in the log when the network is down
6> Jan 6 19:52:05 0.0.0.0-1 UNKN: dot1s_txrx.c(158) 70678 %% dot1sBpduReceive(): paddedBufHandle is L7_NULL
and this log when its up
<5> Jan 6 19:52:41 0.0.0.0-1 TRAPMGR: traputil.c(663) 70679 %% Spanning Tree Topology Change: 0, Unit: 1
An help or advice?
