Цитата:
Just because its not configured or not configurable doesn't mean its not
actually doing it (it may be a bug).
I have an Ethernet over FrameRelay Radio PTMP system that after a few
months of uptime inserts the UDP payload of customer A into the
TCP payload of customer B (customer B using this TCP session to
transfer files to a AS400 that doesn't check TCP checksums and
therefor the UDP payload of customer A makes it into the application
of customer B). The only fix here is to reload the whole system.
The very same PTMP system sometimes drops traffic of a certain mac
address, although there are no layer 2 rules (other that different
vlans).
Just because the box isn't supposed to interact with a specific OSI layer doesn't mean its not actually doing it.
