Settings Description
IP Range Enabled Enables the IP Range checking feature, which defines a specific
range of IP addresses that can access the CMC.
IP Range Address Determines the base IP address for range checking.
IP Range Mask Defines a specific range of IP addresses that can access the
CMC, a process called IP range checking.
IP range checking allows access to the CMC only from clients
or management stations whose IP addresses are within the user-
specified range. All other logins are denied.
For example:
IP range mask: 255.255.255.0
(11111111.11111111.11111111.00000000)
IP range address:192.168.0.255
(11000000.10101000.00000000.11111111)
The resulting IP address range is any address that contains
192.168.0, that is, any address from 192.168.0.0 through
192.168.0.255.
