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 255.255.255.252 uses the 4th octet of a given Autho-
rized Manager IP address to authorize four IP addresses for management
station access. The details on how to use IP masks are provided under
“Building IP Masks” on page 10-10.
Note The IP Mask is a method for recognizing whether a given IP address is
authorized for management access to the switch. This mask serves a different
purpose than IP subnet masks and is applied in a different manner.
