LINX also runs mixed media (sadly) - FDDI and more sane things (GigE and Fast Ethernet). The switches here fragment when switching toward Fast Ethernet. They would certainly move >1500 byte pings between FDDI ports, but I have no FDDI ports now to test whether this works with DF set (i.e. it doesn't fragment FDDI to FDDI), nor whether ICMP is *ever* generated. However, I believe best practice at LINX is, and perhaps should be elsewhere, to set MTU on your FDDI interfaces to that supported by ethernet. Given most exchanges started with ethernet and worked upwards, this should have been best practice everywhere from teh start. -- Alex Bligh VP Core Network, Concentric Network Corporation (formerly GX Networks, Xara Networks)
