I have two cisco 2610 routers with internal T1 DSU's within them, they\nare connected to each other via the T1 DSU using a T1 cross over. I\nset up the "circuit" between the two as a PPP on the serial 0/0\ninterfaces using timeslots 1-2 which should be a 128k circuit.\n\nI have each of these routers then plugged into a switch, one switch\nconnects to the LAN and the other has a stand alone PC and VoIP phone\nhanging off of it.\n\nCommunication works fine between everything, LAN to remote PC and VoIP\nphone and such.\n\nNow, the question is, I have a PC on the LAN running WAN Killer to the\nPC on the other end of the 128k circuit we created between these two\nrouters. I have it set to like 120% of a 512k circuit, which should\nquarantee packet loss or something. I want to see degraded traffic\nand problems. While running this WAN Killer I can ping the same\ninterface WAN Killer is suppose to be slamming with traffic and well\nmy pings come back perfect with no lost packets.\n\nWAN Killer appears to be doing what it is suppose to however the\nrouters don't seem to be limiting traffic between the T1 DSU's to\n128k, despite having only timeslots 1-2 available.\n\nAny clues as to what I am missing? Should the circuit not be dropping\npackets left and right?\n\nMy plan is to get traffic to a certain level, and show all the lost\npackets and stuff. Then try a voice call and see how bad it works if\nit works, then try to implement measures that insure the phone call\nwill work as planned and the other traffic will take a back seat.
