Yes. On the 2950, set the port to 10Mbps, half-duplex, no flow
control, no spanning tree:
int fastethernet 0/xxx
speed 10
duplex half
flow none
spanning-tree portfast
no shutdown
or somesuch. The Cisco ASIC's hate the VAX ethernet port, same
here on my 4000. Basically, the ether connection is bouncing
between between various modes, making it slow and such.
