The management port on the 3850 switch does not rise
When I prescribe the port MGMT(gi0/0) - no shutdown,
cisco display the message:
% HMANRP-6-EMP_NO_ELECTION_INFO: Could not elect active EMP switch, setting emp active switch to 0: EMP_RELAY: Could not elect switch with mgmt port UP
tell me what is the problem? configuration out of the box
There are some bugs reported kind of symptoms but not particular to the model you mentioned, the version you running is cisco stable - but i see some bugs related to that version in our environment also.
moving to the next level may fix issues .-cat3k_caa-universalk9.16.12.04.SPA.bin. ( read the release notes before upgrading).
- Probably a bug as can be seen from these bug reports , albeit for different platforms, but very indicative :
