We have a small network but do a lot of file transfers/backups, so I'm upgrading everything to gig-e and trying to get jumbo frames working.
We have a decent managed switch that supports jumbo frames, and a cheap router (for wifi/dhcp/gateway) that does not.
All pc's (which have jumbo turned on) are plugged into the switch (which also has jumbo turned on), and the switch is plugged into the router.
Naively, I expected to be able exchange jumbo packets between the jumbo-enabled devices on the switch, and anything going to wlan would get fragmented. This seems not to be the case... "ping -f -l 2000 " from one device on the switch to another fails, saying the packet must be fragmented.
First, should this configuration work at all? If so, can anyone suggest further troubleshooting?
