Configuring one station per Authorized manager IP entry

This is the easiest way to apply a mask. If you have ten or fewer management and/or operator stations, you can configure them by adding the address of each to the Authorized manager IP list with 255.255.255.255 for the corresponding mask. For example, as shown in The show authorized-managers command with access method configured, if you configure an IP address of 10.28.227.125 with an IP mask of 255.255.255.255, only a station having an IP address of 10.28.227.125 has management access to the switch.

The “255” in each octet of the mask specifies that only the exact value in that octet of the corresponding IP address is allowed. This mask allows management access only to a station having an IP address of 10.33.248.5.
