To Authorize Manager Access

This command authorizes manager-level access for any station with an IP address of 10.28.227.0 through 10.28.227.255:

switch(config)# ip authorized-managers 10.28.227.101
255.255.255.0 access manager

Similarly, the next command authorizes manager-level access for any station having an IP address of 10.28.227.101 through 103:

switch(config)# ip authorized-managers 10.28.227.101
255.255.255.252 access manager

If you omit the <mask bits > when adding a new authorized manager, the switch automatically uses 255.255.255.255. If you do not specify either Manager or Operator access, the switch assigns the Manager access.
