timeout on switch interconnection

[Joe_Lwe]

Hi, I have used patch panels on both sides and crossover patch codes to interconnect x450a-48p switches.. but am getting request timeouts on host computers.. and switches blink like stp problem (cisco).. NB i have fibre interconnecting switches.. i need to add ethernet to increase bandwidth but now am confused. Please advise.. thanks

Look at the following article how to create a LAG on the x450a:

If you want to use two (or more) parallel connections between two switches to increase bandwidth, you need to configure port sharing (also known as a Link Aggregation Group (LAG) or a Port-Channel).

You need to build ether channel on Cisco side, and lacp lagg on extreme side. Also, you don't need to use crossover patches, because ports are auto MDI/MDI-x
