Station Per Authorized Manager IP Entry” on page 10-9.)
■
Authorizing Multiple Stations:
The table entry uses the IP Mask
to authorize access to the switch from a defined group of stations.
This is useful if you want to easily authorize several stations to have
access to the switch without having to type an entry for every station.
All stations in the group defined by the one Authorized Manager IP
table entry and its associated IP mask will have the same access
level—Manager or Operator. (For more on this topic, refer to “Config-
uring Multiple Stations Per Authorized Manager IP Entry” on page
10-10.)

Overview of IP Mask Operation
The default IP Mask is 255.255.255.255 and allows switch access only to a
station having an IP address that is identical to the Authorized Manager IP
parameter value. (“255” in an octet of the mask means that only the exact value
in the corresponding octet of the Authorized Manager IP parameter is allowed
in the IP address of an authorized management station.) However, you can
alter the mask and the Authorized Manager IP parameter to specify ranges of
authorized IP addresses.

in the IP address of an authorized management station.) However, you can
alter the mask and the Authorized Manager IP parameter to specify ranges of
authorized IP addresses.
For example, a mask of
255.255.255.0 and any value for the Authorized Manager
IP parameter allows a range of 0 through 255 in the 4th octet of the authorized
IP address, which enables a block of up to 254 IP addresses for IP management
access (excluding 0 for the network and 255 for broadcasts). A mask of
