Analyzer Ports for dedicated mirroring of the
network traffic (providing SPAN and
TAP functionality).
TAP Instructs the 10G Network Active
Bypass unit to passively monitor
network traffic and mirror that data
to a monitoring port without
interfering with the data stream.
The 10G Network Active Bypass unit
is capable of mirroring single-port or
aggregated multi-port traffic to a TAP
port.
Note: The 10G Network Active
Bypass unit provides seven
functioning TAP ports (1 through 7).
TAP port 8 is not available for use.
