[Soekris] Compatibility Issue w/ Soekris 5501 and Cisco 2640 Switch

[Chuck (Doc) Beaudette]

I have noted what appears to be a compatibility issue between the new
Soekris and Cisco 2640 switch. I previously had a 4801 in my network
connected to a Cisco 2640 for customers on a local Fiber network. The 4801
acted as the router between the fiber switch and our Cisco border router.
Average 95th percentile traffic was about 15-20mb for customers on this
network. Customers had good burst rates of 40mb and better. 

When I replaced the 4801 with a new 5501, the throughput between the Cisco
2640 and the Soekris router dropped to next to nothing. We tried several
different configurations (Auto negotiate, fixed 100mb Full-Duplex, etc.),
nothing seemed to make any difference. Finally, we put a Netgear switch
between the Cisco 2640 and the Soekris 5501 which cleared the problem. The
2640 is an older swtich, so the next option is try an upgrade to a 2660
switch then see if we can connect the Soekris directly.

Anyone know of similar issues with the 5501?
