Configuring Interface and Connection Snooping

Snooping allows the cells from all connections, in either receive or transmit direction, on a selected
physical port to be transparently mirrored to a snoop test port where an external ATM analyzer can be
attached. Unlike shared medium LANs, an ATM system requires a separate port to allow nonintrusive
traffic monitoring on a line.
Note Only cells that belong to existing connections are sent to the snoop test port. Any received cells that do
not belong to existing connections are not copied. In addition, the STS-3c (or other) overhead bytes
transmitted at the test port are not copies of the overhead bytes at the monitored port.
