The SNMP Agent Administrative value of the IP Address
for the system.
This value is stored in the system NVRAM.
The current operational IP Adress may be obtained by
accessing the ipAdEntAddr entry in the ipAddrTable for
ipAdEntIfIndex equal to the system interface value.
If the system has no current operational IP Address,
meaning that the access is done out-of-band, then this
value takes effect immediately. In this case the
NetMask and the BcastAddr will be automatically built.
Otherwise it will take effect after a system reset.
