Configuring IP filtering using RACADM

You must have Configure privilege to perform these steps.
To configure IP filtering, use the following RACADM objects in the iDRAC.IPBlocking group:
  • RangeEnable
  • RangeAddr
  • RangeMask

The RangeMask property is applied to both the incoming IP address and to the RangeAddr property. If the results are identical, the incoming login request is allowed to access iDRAC. Logging in from IP addresses outside this range results in an error.

The login proceeds if the following expression equals zero:
RangeMask & (<incoming-IP-address> ^ RangeAddr)
&
Bitwise AND of the quantities
^
Bitwise exclusive-OR

Examples for IP Filtering

The following RACADM commands block all IP addresses except 192.168.0.57: 
racadm set iDRAC.IPBlocking.RangeEnable 1
racadm set iDRAC.IPBlocking.RangeAddr 192.168.0.57
racadm set iDRAC.IPBlocking.RangeMask 255.255.255.255
To restrict logins to a set of four adjacent IP addresses (for example, 192.168.0.212 through 192.168.0.215), select all but the lowest two bits in the mask:
racadm set iDRAC.IPBlocking.RangeEnable 1
racadm set iDRAC.IPBlocking.RangeAddr 192.168.0.212
racadm set iDRAC.IPBlocking.RangeMask 255.255.255.252
The last byte of the range mask is set to 252, the decimal equivalent of 11111100b.
