Using the captured packet dump

You can view packets using a ACLI session and the Secondary SF/CPU. Dumping a large
number of captured packets is CPU intensive. The switch does not respond to any commands
while the dump is in progress. Avaya recommends you use this command only when it is
absolutely necessary. However, there is no degradation in normal traffic handling or switch
failover.
