HI Group,
I have been running a VLAN configured system for some years using 10/100
Sundance driver cards without a problem. I recently tried on a HP
proliant server using gigabit cards and found a problem related to the
MTU size for the interface I an using.
The 10/100 cards seem to need a MTU of 1504 bytes, but this size does
not work with the e1000 gig cards, or the US robotics, Dlink DGE,
broadcom etc. I have to move the MTU down to 1500 to make fragmentation
work and allow it to pass the larger packets.
Is this what I should expect from the e1000, broadcom, R8169 drivers for
gigabit cards?
The 10/100 drivers are the sundance driver. I am using Allied telesyn
8000s/24 switches to detag the incoming tagged data stream and a PC on
the unagged port of the allied switch.
2.6.21 kernel based on fedora 5.
vconfig version vconfig-1.9-2.i386.rpm
