Probably because your suppliers run everything thru their lawyers. This
obviously was posted straight via the NOC/OPs group. They'll continue to
post incident reports like this until they get hit by their first lawsuit
by someone similar to "spilling hot coffee on their lap".
"This take somewhat longer than it should have..."
"then we are pretty sure that the measures above (enforcing MAC count
limits on every port, disabling keepalives on interswitch links, single
homing all 2950's) will prevent the problem from reoccuring..."
There is enough info in that posting to bury them in frivilous lawsuits.
