I think this is an issue with default VLAN membership.
I don't think it's where the problem lies, otherwise even a simple ping
wouldn't work. The problem here explicitly arises when packets are
fragmented...
fragmentation?
I think, you use ethernet links, all have 1500byte max packet size,
you have 1500byte packet size also comfigured at the vlan interface, so..
why do you think anything should start fragmenting?
(and tagged vlan frames are bigger than 1500byte at the "raw" ethernet
link).
check for maximum mtu that can travel over the link.
(ping -s 1472 for 1500byte packet)
switchport trunk encapsulation dot1q
There's no such option, I believe it's implicit in the trunk mode...
and put the server back to back and remove the switch, just to be shure
the switch is not the problem.
Kind regards,
Ingo Flaschberger
