You can use what is called "The poor mans traffic generator" It is the CHARGEN application built into the router. You first need to enabled TCP and UDP small services on the router (TCP and UDP port 19). Then you can do a telnet to the remote device and add the parameter chargen to it. ex. telnet 10.10.10.10 chargen
This will start generating traffic to the remote telnet address...Good Luck..Pls rate..
"can someone explain how to use traffic generator in live environment?"
Place traffic generator on one side of router and have it generate traffic that should be routed across the router. Depending on what type of traffic you're generating, a "sink" (destination device that accepts and terminates traffic - some can also echo traffic) might be required on the other side of the router.
If you generate full bandwidth traffic on one link, you can often hit the max performance of the smaller "pure" routers. On the more powerful "pure" routers, it might take several links of max bandwidth to hit the max. On L3 switches, some can take all links running at full bandwidth. (L3 switches often require dedicated hardware traffic generators to push that much bandwidth.)
"where i get traffic generator software"
They can be purchased, but there are some simple ones that are free. Recently, I've discovered one, pcattcp (Windows), that is a variant of TTCP but it also can generate UDP packets at defined transmission rates. The latter good for filling links or the small routers.
Don't forget, using such traffic generators can disrupt production traffic performance. (Also good to test QoS.)
Try using the IPerf software. It is free and you can find it on the web. It works by setting up one end as a server and the other as a client. You can pecify what type of traffic to send (UDP or TCP). You can flood your WAN links pretty good with this. Also you can adjust the TCP window size to long links to tweek your TCP parameters... Try it out...

Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
see the following directory full or nearly ...
