Traffic Generation using Cisco Pagent TGN (Traffic GeNeration) Module

Below shows the sample configuration for generating 1000 ICMP Echo Request packets with random length between 500 and 1000 bytes, per second.

pagent1(TGN:OFF,Fa0/0:1/1)#start

You have started traffic generation in dedicated output-mode.
TGN will go into a send loop that locks out all other processes.
Enter control-6 or shift-control-6 to stop traffic generation.
