Hello everyone,
I would like to count on your support to try to figure out the root of the following issue.
The company has bought two Aruba 8300 and I am trying to configure the chassis to be able to be connected to the current two Aruba cx 6300 switches, but for some reason I am getting the following error, LACP-BLOCK. I have reconfigured the switches several time and the issue persist.

The vsx is syncronized and everything looks good, I am sharing with you the current config for the CX8320 primary and secondary and also the CX6300.
