Troubleshooting tools
• For AsrcBdst mode, you can only configure one port as the monitor port, source MAC
address A and destination MAC address B. (monitoring traffic with source MAC address
A and destination MAC address B).
• For AsrcBdstorBsrcAdst mode, you can only configure one port as the monitor port,
source MAC address A and destination MAC address B. ((monitoring traffic with source
MAC address A and destination MAC address B) OR (source MAC address B and
destination MAC address A).
• For AsrcorAdst mode, you can only configure one port as the monitor port, source/
destination MAC address A. (monitoring traffic with source OR destination MAC address
A).
• For ManytoOneRx, you can only configure one port as the monitor port and up to the rest
of the ports as mirrored ports. (monitoring traffic received by all mirrored ports).
• For ManytoOneTx, you can only configure one port as the monitor port and up to the rest
of the ports as mirrored ports. (monitoring traffic transmitted by all mirrored ports).
• For ManytoOneRxTx, you can only configure one port as the monitor port and up to the
rest of the ports as mirrored ports. (monitoring traffic transmitted AND received by all
mirrored ports).
You can observe and analyze packet traffic at the mirroring port using a network analyzer. A
copy of the packet can be captured and analyzed. Unlike other methods that are used to
analyze packet traffic, the packet traffic is uninterrupted and packets flow normally through the
mirrored port.

Port Mirroring commands

Refer to the Configuring System Monitoring on Avaya Ethernet Routing Switch 5000 Series,
NN47200-505 for port mirroring command information.
You can use the port mirroring commands to assist in diagnostics and information gathering.

Port Statistics

Use port statistics commands to display information about received and transmitted packets
at the ports. The ingress and egress counts occur at the MAC layer. Count updates occur once
every second.
