Brocade to Dell switch lag issue

[jeff_francis]

Having issues configuring a new Dynamic Lag between Brocade ICX 6610 to Dell s4112t-on, both switches on the latest firmware.  Configuration looks good on both sides but no success.  I have tested the Dell switch to a cisco switch I had recently taken out of service and that lag works.  I have also tested the Brocade stack to that same cisco switch and it works.  When I connect the Dell Switch to the Brocade switch, the ports show as up however in a BLOCKED state.  Port is up, line protocol is down (LACP-BLOCKED)  Port down (LACP-BLOCKED). 

Any suggestions/ideas/tips would be GREATLY appreciated.

Hi Jeff,

Pls check if the ports have the same speed & duplex on both ends, Also try to match the lacp timeout configured on both sides.

Hope they are not blocked by STP.

Thanks
