Are you referring to this command?
(S3500-48P-US) (config) #mgmt-?
mgmt-server Register Mgmt Server IP Address with the controller.
This could be AirWave Management Server or any other
server that would like to receive messages from the
controller using AMON protocol
mgmt-user Configure a management user.
The MAS does not currently use AMON to communicate with Airwave. I'll talk with engineering about hiding this command.
The MAS currently uses SSH/Telnet, SNMP and Syslog with Airwave.
