Hi everyone,

What does C9500 STACK log mean? Are there any Cisco documentation for this log? 

%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

Thanks

is this Cat 9500 or Cat 9300 ?

Cat 9500 does the Stackwise virtual

Cat 9300 do Stacking (traditional way)
