Cisco 3560 switch compatability with Motorola ptp 58400

How do I configure a Cisco 3560 to work with a Motorola ptp 58400 microwave system?  I have them set up, but every ten minutes or so, the switch dropps the lan signal.  It appears to be an autoconfig issue, but I have manually configed both sides at 100meg full duplex.  Please help.

loopguard is not an option on the port, but it is in general config mode, so I will try it.
