Only heard this second hand but we've had a failure in our internet connection in the building. There may have been an upgrade while dealing with the issue.
Everything's back to normal except for a small network behind a Cisco asa5505. Bypassing the switch works so the technician advised us to get a new switch since it was probable that the cisco switch "doesn't support the type of ip-address used".
Does that sound like qualified bullshit to you? It does to me.
Will attempt to sort it out but for the moment I can't get a hold of the user credentials.
