Property
cfgRacTuneIpRangeEnable Enables the IP range checking feature.

Enabling IP Filtering
Below is an example command for IP filtering setup.
See "Using RACADM Remotely" on page 111 for more information about
RACADM and RACADM commands.
NOTE:
The following RACADM commands block all IP addresses except
192.168.0.57)
To restrict the login to a single IP address (for example, 192.168.0.57), use the
full mask, as shown below.
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeEnable 1
racadm config -g cfgRacTuning -o
cfgRacTuneIpRangeAddr 192.168.0.57

Configuring Security Features
Description
Determines the acceptable IP address bit pattern,
depending on the 1's in the subnet mask.
This property is bitwise AND'd with
cfgRacTuneIpRangeMask 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.
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.
