TFTP doesn't use TCP. It uses UDP, plus its own stop-and-wait retransmission protocol. TFTP records are a fixed size, IIRC 512 bytes. Remember that TFTP was originally designed to fit into a small ROM, which couldn't possibly hold TCP. Full TFTP implementations usually are under 10K bytes. > >FWIW.... > >Annlee Hines >""Ozzie Sutcliffe"" wrote in message >[EMAIL PROTECTED]">news:[EMAIL PROTECTED]... >> When I do the TFTP lab in class.. >> I have 6 routers 6 PC and 6 Xover cables >> All have the same configs except for IP addy's >> Yet when the class pulls down the IOS the times for a 7 meg bin file vary >> from 4 to 15 minutes. >> The cables are all the same length same company who made them. >> The routers are all 1601's the pc's and NIC's the same all running windoze >> 98 SE. >> Ideas anyone ?? >> This week I will sniff each PC and see what that bring up . >> >> >> Ideas anyone ?? >> >> >> I will post the results next saturday >> >> Oz Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=35067&t=35006 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
