Aruba LACP

Hi everybody.

I'm reasonably new to Aruba so just looking for a bit of direction with an LACP issue I'm having.

Background: I'm doing some work for an organisation that has grown a fair bit so we've installing a core/distribution layer pair of 8320's. Access switches are a mix of Aruba 2530 and 2540s.

We're looking to run MCLAG for links to access switches but for some reason the LACP is getting blocked. VSX has been configured on the 8320's and looks to be operating just fine.

Any experience Aruba people out there can point out what I've missed?

Cheers in advance.
