The login proceeds if the following expression equals zero:
cfgRacTuneIpRangeMask & (<incoming_IP_address> ^
cfgRacTuneIpRangeAddr)
where & is the bitwise AND of the quantities and ^ is the bitwise
exclusive-OR.
See "DRAC 5 Property Database Group and Object Definitions" on page 345
for a complete list of cfgRacTune properties.
Enabling IP Filtering
Below is an example command for IP filtering setup.
See "Using RACADM Remotely" on page 78 for more information about
RACADM and RACADM commands.
NOTE: The following RACADM commands block all IP addresses except

Table 12-15. IP Address Filtering (IpRange) Properties
Property Description
cfgRacTuneIpRangeEnable Enables the IP range checking feature.
cfgRacTuneIpRangeAddr 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 a DRAC 5 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 a DRAC 5
session.
cfgRacTuneIpRangeMask 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.
