Virtual PC slow down TFTP file transfer
août 19th, 2008
If you want don’t want to see your TFTP file transfer looking like 259bytes/second between Cisco ASA and your Windows XP workstation, don’t forget to close Virtual PC machine.
Today I initiated a TFTP file transfer from a freshly out-of-the-box Cisco ASA and a Solarwinds TFTP server hosted on a Windows XP workstation. Traffic was very very slow. Show interfaces reported 5 minute output rate 0 pkts/sec, 259 bytes/sec
So what the fuck? I was very skeptical on this issue .. Ran Wireshark and no interface was available except generic dialup. And here comes the idea in my brain: I’m running Debian in Virtual PC. No IT can’t be ?? Yes, don’t blame the network so early in your troubleshooting steps.. VPC was the root problem 
Click here to see the TFTP transfer speed changing over time !
Wanna dream of QoS rate limiting without adding a unique line of configuration ? Run Virtual PC!
