TCAM write failure message on 3750x stack

[Charlie Jones]

Good morning,

I have a stack of 3750x switches running 15.0 (2) SE2 IOS.   When I reload the switch stack, I am seeing the following message in the logs:

IPv6 user port trust TCAM write failed

Any ideas on what is causing this?

Hi Charlie,

Error:

IPv6 user port trust TCAM write failed

Basically, these error messages are cosmetic. They correspond to an internally indentified bug. Currently, this is being worked so it can be fixed, and it will take some time for that bug to become public.

In the meanwhile, we can totally assure that these logs will not affect the switch performance at all, as long as you have not turned on any IPv6 features on the switch. Therefore, you can just ignore these messages.

HTH

Thanks for the response.  After I posted this, I reached out to our Cisco support rep and he mentioned that it was a bug as well.
