Hi Folks,
I am having a hard time to get a trunk link working between Cisco 4500X and Brocade VDX 6740
Network Diagram attached, there are currently 4 Interfaces connected between two switches as port-channel and it's access port, the new link I am connecting is a trunk link so I can test few things before converting the port-channel to a trunk.
Issue: whenever i bring the new link up all ports in the port-channel goes into error-disabled state
Logs below
appreciate any help on this.
