Folks,
I have a Gb managed dell 5340 that seems to be choking on larger packets. While the ping command offers datagram size up to 65535, and I have used that size (usually use 65000 instead). Pinging thru the switch, from a cisco ASA to a NAS server, it starts having trouble around 30000 (60 to 100% loss, if I do it several times or if I set repeat to 100 I get 83%). At 40000 I get no replies, 100% loss
Anyone know what the normal frame size is?
Are there any negative repercussions I should be aware of before enabling "Jumbo Frames" on the switch? And is this likely to help?
The functional problem is tape backup is running about 5% expected speed when going from the NAS through the switch to the backup server through the scsi to tape it's slow. From the backup server through the scsi to tape it's fast (useless to us, but done as a test. We are trying to backup a 3.5 GB iso image and a 6GB folder of misc. files, seperately, just as a test.
TIA,
knudsen
