We have an issue with a Ceragon IP10 FibeAir radio link:

a) When connected to a HP ProCurve 10/100 OR Gbit (two different switches), auto-negotiate works fine, and the IP10 connects at proper speed (100 or 1000Mbps).

b) When connected to a Cisco 2960-S (Gbit Ethernet), the IP10 starts behaving weird:
  1) Using auto-negotiate: IP10 Ethernet interface goes down, switch port shows no link
  2) Disabling auto, setting 100/FD: Port comes up, but throughput is below 10Mbps
  3) Any other combination of fixed speed/duplex: No link

c) When connecting the IP10 back to the ProCurve, and then back to the Cisco - everything works like a charm (just using the ProCurve to handle the IP10).

Any ideas what might be causing this? And how to fix it?
