Port Statistics; Route Tracing - Avaya Virtual Services Platform 7000 Series Troubleshooting Manual

received by port Y {(traffic received by port X AND transmitted by port Y) OR (monitoring
traffic received by port Y AND transmitted by port X)}.
• For Adst mode, you can only configure one port as the monitor port and destination MAC
address A. (monitoring traffic with destination MAC address A).
• For Asrc mode, you can only configure one port as the monitor port and source MAC
address A. (monitoring traffic with source MAC address A).
• 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 or
destination MAC address A. (monitoring traffic with source OR destination MAC address
A).
You can observe and analyze packet traffic at the mirroring port using the Avaya StackProbe
or equivalent. Unlike other methods that are used to analyze packet traffic, with port mirroring
a copy of the packet can be captured and analyzed, so the packet traffic is uninterrupted, and
packets flow normally through the mirrored port.
For information about configuring port mirroring using ACLI or EDM, see Virtual Services
Platform 7000 Series Configuration — System Monitoring (NN47202-505).

Port statistics

Display port statistics to view information about packets received and transmitted at switch
ports. The ingress and egress count updates occur once every second at the MAC layer.

Route tracing

Route tracing can display the route taken by IP packets to a specified host. For a stack
configuration, you can preform this procedure only on the base unit.
You can use the traceroute command to send a sequence of User Datagram Protocol (UDP)
probe packets to a specified host. You can adjust the time-to-live (TTL) IP parameter to
determine the intermediate routers traversed. Traceroute displays a list of routers and the
packet latency values during the route.
