Building IP Masks
The IP Mask parameter controls how the switch uses an Authorized Manager
IP value to recognize the IP addresses of authorized manager stations on your
network.
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 quickly by simply 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 figure 8-3 on page 8-6, 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.
