TX drops in general are caused by insufficient capacity on the interface where traffic needs to be sent. If you have more than 1 Gbps of traffic, and a 1 Gbps port, then traffic needs to be dropped when buffers fill up. One thing that may cause this is excessive broadcast or loops in your network.
This is not an Aruba switch problem, but a switching capacity design in general. Would be good to get your Aruba partner involved to review your design, first review the links and link capacity.

Subject: Packet drops on Aruba 25xx and 29xx interfaces
Hi!
We have few Aruba 2540 and 2930 and I can see TX drops on many interfaces. Its not just one switch its almost all the switches. This is only 1G ports and 10G ports. I was told that this can be buffer issue.
Just want to check with the community if they have seen the same issue with their Aruba Switches.
Thanks for your input.
