Re: Traffic Generator

Hey team, good evening,

A little off topic from what you all are suggesting, however ... a
suggestion I might offer for your lab testing and lab prep. Also a nice way
to learn QoS and IP SLA.

On some routers, use IP SLA to send traffic:

ICMP packets (can increase the packet size)
TCP packets (I use port 23 in mine so I can match on the telnet protocol)
UDP packets (can easily increase the frequency)

One some other routers, use MQC to match these ports numbers and or traffic
types. Then use the show ip policy-map command to check your QoS configs.
On the sending routers, the two 'MUST HAVE" commands are: show ip sla config
and show ip sla stat

You can create different 'apps' on one end and then test your QoS configs on
the other end.

I would also suggest to add this to EVERY lab you practice. HTH team and
have a great night,

Andrew

PS - there are a lot of options with IP SLA ... and this might be a good way
to learn them.
