gs108v2 gs308ep DoS

I have both of those switches... The port turns off and has to be enabled to back on.

 

The gs108v2 is connected to the gs308ep (poe is turned of on port 1 which connects to the gs108v2 port 1). There is a cisco access point connected to the gs308ep.

 

The gs 108v2 log show this:

 

<11> Nov 27 15:21:43 192.168.2.*-1 DOS[2169089684]: broad_system.c(4623) 16066 %% Dos Attack:ICMP erroneous packet received on the interface 1 

<11> Nov 27 15:21:45 192.168.2.*-1 DOS[2178647972]: dos_api.c(586) 16068 %% Interface 1 has been shut down by Dos attack notification

 

What has to done to fix this? This seems to be triggered by an iphone or either the router which has a static address connected to the gs108v2 switch. I just can't see it being the router? Their seems to other post around about this but no real fixes? Both switches have current firmware updated.

 

Thanks

    This particular model is an unmanaged switch - so no logs.

     

    Are you sure you have the exact model info?

    Or did you mean to say the GS308ep log?

      Correct it's a smart switch not a fully managed switch... The model info I gave is correct also.

       

      Thanks for the reply.

        Are you sure you didn't mean the GS108eV2 or the GS108Tv2?

         

        The GS108T has a control to disable DOS attacks, the GS108e doesn't (at least nothing in the manual)
