I'm trying to troubleshoot a situation between a foundry sx and a brocade icx. I setup tagged ports and vlans between them both. Now when I connect the 2 switches with an ethernet cable, ospf comes up and everything works nicely however when I connect them using fiber, they fail to establish any adjacencies nor can I ping between them even with private ip's.
On the sfp ports for the icx, it says to configure the ports manually to: 1000-full-master and the other end to 1000-full-slave which I did. The link comes up but I can't pass any traffic between them.
Any ideas on why this may be at all?
