Cause and
correction
Assumed cause Correction Prevention
A network convergence occurred. The load on the network is too high.
Check whether there are nodes that
send unnecessary broadcast frames
on the network and remove them.
After that, check that the received
number of frames has reduced in the
network statistical information.
Make sure that unnecessary broad-
cast frames are not sent on the net-
work. Do not connect the Ethernet
cable in a loop.
