Admin Tab - Port Mirroring
Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets from
one port to a monitoring port. Port mirroring can be used as diagnostic tool and/or a debugging feature. Port
mirroring also enables switch performance monitoring.
Network administrators configure port mirroring by selecting a specific port to copy all packets, and different
ports from which the packets are copied.
Source Port. Defines the port to which traffic is mirrored.
Type. Indicates the port mode configuration for port mirroring. The possible field values are:
• RxOnly. Defines the port mirroring on receiving ports. This is the default value.
• TxOnly. Defines the port mirroring on transmitting ports.
• Both. Defines the port mirroring on both receiving and transmitting ports.
Target Port. Defines the port from which traffic is mirrored.
Admin Tab - Cable Test
The Cable Test screen shows you results from performance tests on copper cables. The maximum cable length
that can be tested is 120 meters. Cables are tested when the ports are in the down state, except for the
Approximate Cable Length test.
Port. This is the port to which the cable is connected.
Test Result. This is the test result. OK indicates that the cable passed the test. No Cable means there is no cable
connected to the port. Open Cable means the cable is connected on only one side. Short Cable indicates that a
short has occurred in the cable. Undefined indicates that the test could not be properly performed.
Cable Fault Distance. This is the distance from the port at which the cable error occurred.
Last Update. This is the last time the port was tested.
Test. Click the Test button to perform the test.
Cable Length. This is the approximate length of the cable. The Cable Length test can be performed only when the
port is up and operating at 1Gbps.
