Hello,
we've a WS-C3850-24T running software 16.09.06 with ipbasek9 license. When we tried to put the config to the interface we got below,
c3850(config-if)#mka policy mkapolicy1
% GCM-AES-256 is not supported
% Cannot apply MKA Policy "mkapolicy1"...
- Interface is not MACsec capable.
Any ideas why this happened?
Thanks!

- I am not sure it can work with that 'software level' could you have a go with a universak9 image as in :

Thanks for your reply but according to release notes on CCO Macsec MKA was support from 16.9.1
128-bit—(IP Base and IP Services)
256-bit—(IP Services)

- I though that the mka policy command was a global configuration setting not per interface , you may try that.

Yes I know, MKA policy is global under interface looks like this,
macsec network-link
mka pre-shared-key key-chain XXX

Check if the described workaround can be applied to your case too.
