- Active—Both source and destination interfaces are up and forwarding
traffic.
- Not Ready—Either source or destination (or both) are down or not
forwarding traffic for some reason.
STEP 2 Click Add to add a port or VLAN to be mirrored.
STEP 3 Enter the parameters:
• Destination Port—Select the analyzer port to where packets are copied. A
network analyzer, such as a PC running Wireshark, is connected to this port.
If a port is identified as an analyzer destination port, it remains the analyzer
destination port until all entries are removed.
• Source Interface—Select the source port or source VLAN from where
traffic is to be mirrored.
• Type—Select whether incoming, outgoing, or both types of traffic are
mirrored to the analyzer port. If Port is selected, the options are:
- Rx Only—Port mirroring on incoming packets.
- Tx Only—Port mirroring on outgoing packets.
- Tx and Rx—Port mirroring on both incoming and outgoing packets.
STEP 4 Click Apply. Port mirroring is added to the Running Configuration.
