2930M Transceivers & LACP

I just purchased 3 2930m switches and have placed them in a stack.  I need to connect them to my core stack "Brocade" using lacp.  I purchased the Aruba J9151D transceivers and have them both plugged into the stack.  I am using Brocade transceivers in the core stack and I am unable to get the lacp link to work.  One thing I tried was to put a Brocade transceiver in the Aruba stack, enable the non-supported-transceiver and the link comes up.  If I put an Aruba transceiver in the core Brocade stack the link also comes up.  I assume this is an issue on the Aruba side or am I missing a command?

Are the links coming up and the LACP LAG not forming?  Or is there no link at all?

 

With the Aruba transceivers in the 2930M switches, can you do a "show tech transceivers" and paste the output?

The links comes up but when I do a show lacp "Partner" is no unless I use the same transceiver on each end.

What's the model # of the Brocade transceiver?  You have LR type Aruba transceivers, can you confirm you have LR on Brocade as well?

We are currently using Brocade 57-0000075-01

10G SR (the Brocade Xcvrs) and 10G LR (the Aruba ones) use different wavelengths, hence no connectivity. 

 

You need to match the technology types on both ends:  SR to SR (uses Multimode Fiber) or LR to LR (over Singlemode Fiber).
