Does the Cisco make proper IP (de-)fragmentation?
E.g. the 3COM LANplex (?) 2500 is knowen to have "problems" with this.
Try to set the MTU on the FDDI interface to 1500 bytes?

BTW: Good news for all NetBSD useres with big endian machines and DEFPAs:
The obscure big endian bug in the DEF[TEP]A driver is gone.

Connect temporary disk to Alpha, tar data on raw disk, move disk to 
Octane, untar.
