Interconnect between Cisco 2970 and 3Com Core Builder 9000

Any one have this issue of trying to Interconnect Cisco 2970 and a 3COM Core Builder 9000? Connecting with the Gig Ports (SX) The 2970 has SFP (SX) Core Builder 9000 has a (SX) GBIC. You get bouncing of the LED on the 2970 orange to green and can`t ping the Core Builder IP Address. Also same results with a 'X' Over Cable on the Copper Ports of the 2 Devices.Thanks, Kirk email address is kirk@microint.com

Hi kirk,

I would suggest that you console into the 2970, check the logs using the "show log" command and find out why the link is going up/down. The error message produced may point you in the right direction.
