authorized IP addresses. For example, a ma sk of 255.255.255.0 and any value
for the Authorized Manager IP parameter allows a range of 0 throug h 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 mas ks 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.
