We have a 2950T switch connected to 3550 12T switch.On the 2950T switch the 100BT ports are used for uplinks from other switches catalyst 2924xl. PC's on the switch FTP to server on the 3550. For a get they have speeds of 5000-6000 bytes per seconds but a put has speeds of 600Kbytes per seconds or less. There do not appears to any errors but there are deffered packets on the ports used as an uplink.
I also connected a PC to the 2950T switch and FTP's to a server on the same switch. A get was 10 times slower than a put (287.62Kbytes/sec. to 2936.69Kbytes/sec.). I moved the server to another 2950T connected in the same way and got the same results. I moved the server to the 3550 and the speed improved ( 3751.11Kbytes/sec.get to put 3102.20Kbytes/sec).
Are there performance problems with the 2950T's used in this way ?
