364 Configuring Security Features
IP Range Address Determines the acceptable IP address bit pattern, depending on
the 1's in the subnet mask. This value is bitwise AND’d with the
IP Range Subnet Mask to determine the upper portion of the
allowed IP address. Any IP address that contains this bit pattern
in its upper bits is allowed to establish an iDRAC6 session.
Logins from IP addresses that are outside this range will fail.
The default values in each property allow an address range from
192.168.1.0 to 192.168.1.255 to establish an iDRAC6 session.
IP Range Subnet
Mask
Defines the significant bit positions in the IP address.
The subnet mask should be in the form of a netmask, where the
more significant bits are all 1's with a single transition to all
zeros in the lower-order bits.
For example: 255.255.255.0
IP Blocking
Enabled
Enables the IP address blocking feature, which limits the
number of failed login attempts from a specific IP address for a
preselected time span.
IP Blocking Fail
Count
Sets the number of login failures attempted from an IP address
before the login attempts are rejected from that address.
IP Blocking Fail
Window
Determines the time span in seconds within which IP Block Fail
Count failures must occur to trigger the IP Block Penalty Time.
IP Blocking
Penalty Time
The time span in seconds within which login attempts from an
IP address with excessive failures are rejected.
