Port Mirroring - NETGEAR GSM7228PS Cli Manual

Port Mirroring

Port mirroring, which is also known as port monitoring, selects network traffic that you can
analyze with a network analyzer, such as a SwitchProbe device or other Remote Monitoring
(RMON) probe.
monitor session
This command configures a probe port and a monitored port for monitor session (port monitoring).
Use the source interface <unit/slot/port> parameter to specify the interface to
monitor. Use rx to monitor only ingress packets, or use tx to monitor only egress packets. If you
do not specify an {rx | tx} option, the destination port monitors both ingress and egress
packets. Use the destination interface <unit/slot/port> to specify the interface
to receive the monitored traffic. Use the mode parameter to enabled the administrative mode of
the session. If enabled, the probe port monitors all the traffic received and transmitted on the
physical monitored port.
Format
monitor session <session-id> {source interface <unit/slot/port> [{rx
| tx}] | destination interface <unit/slot/port> | mode}
Mode Global Config
no monitor session
Use this command without optional parameters to remove the monitor session (port monitoring)
designation from the source probe port, the destination monitored port and all VLANs. Once the
port is removed from the VLAN, you must manually add the port to any desired VLANs. Use the
source interface <unit/slot/port> parameter or destination interface
<unit/slot/port> to remove the specified interface from the port monitoring session. Use
the mode parameter to disable the administrative mode of the session
.
Note: Since the current version of 7000 series software only supports one session, if you
do not supply optional parameters, the behavior of this command is similar to the
behavior of the no monitor command.
