![]() ![]() If only 1 or 2 hosts show packet loss, it's likely just ICMP being dropped at those routers. Use winmtr, or if you have a unix box, use regular mtr, let it run for about 100 or so cycles, it will show loss statistics. traceroute can be misleading, far too many folks see a dropped packet and assume that the first node that dropped it is malfunctioning. It usually means the provider has deployed CoPP and is rate limiting ICMP traffic. )Ĭonsistent packet loss to the same host is actually pretty normal when it's ICMP traffic. (I'm not saying all companies have engineers that know what they are doing by the way. Our NOC usualy deals with the transit providers initially but if I ever have to eventually due to the troubleshooting you've conducted (if it points anything serious out to them) and your persistence can get you through to the cluely engineers within the providers IP teams. The best way to prove to a transit provider that they have an issue is lodge a fault and then hammer them with legitimate troubleshooting results that you have come up with. ![]() HOWEVER - Keep in mind that routers de-prioritize ICMP packets if they are extremely busy doing other things. if you only havea windows machine at your disposal then winMTR or perhaps pathping will give you an idea of which hops along the path could potentially be dropping packets. force it to exit your network via another path other than Verizon and see the problems still exist?ĭownload WinMTR or get a Linux hosts with MTR on it. If you have several can you pick a network that has on of the residing slow loading webpages etc. I take it you only have one outbound path available? I guess my question is, how do I convince Verizon it is their issue? How do you get beyond the L1 support that only knows how to restart your PC/router? It is only when a destination requires traversal from one to the other that I get packet loss. Now, if I run continuous pings to, I have 0 packet loss.
