Using Authorized IP Managers

Building IP Masks

Configuring Multiple Stations Per Authorized Manager

IP Entry

The mask determines whether the IP address of a station on the network meets

the criteria you specify. That is, for a given Authorized Manager entry, the

switch applies the IP mask to the IP address you specify to determine a range

of authorized IP addresses for management access. As described above, that

range can be as small as one IP address (if 255 is set for all octets in the mask),

or can include multiple IP addresses (if one or more octets in the mask are set

to less than 255).

If a bit in an octet of the mask is “on” (set to 1), then the corresponding bit in

the IP address of a potentially authorized station must match the same bit in

the IP address you entered in the Authorized Manager IP list. Conversely, if a

bit in an octet of the mask is “off” (set to 0), then the corresponding bit in the

IP address of a potentially authorized station on the network does not have to

match its counterpart in the IP address you entered in the Authorized Manager

IP list. Thus, in the example shown above, a “255” in an IP Mask octet (all bits

in the octet are “on”) means only one value is allowed for that octet—the value

you specify in the corresponding octet of the Authorized Manager IP list. A “0”

(all bits in the octet are “off”) means that any value from 0 to 255 is allowed

in the corresponding octet in the IP address of an authorized station. You can

also specify a series of values that are a subset of the 0-255 range by using a

value that is greater than 0, but less than 255.
