Settings Description
IP Range Enabled Enables the IP Range checking feature, which defines a range of
IP addresses that can access the iDRAC. The default is off.
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. Log ins 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. The default is 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. The default is off.
IP Blocking Fail
Count
Sets the number of login failures attempted from an IP address
before the login attempts are rejected from that address.
The default is 10.
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. The default is 3600.
IP Blocking Penalty
Time
The time span in seconds that login attempts from an IP address
with excessive failures are rejected. The default is 3600.
