4.3.3 Managing the NPU Boot Mode
The NPU boot mode refers to the mode of operation to be used for operating the
NPU. You can configure the NPU to be operated in any of the following boot
modes:
 ASN-GW mode: In this mode, the NPU implements ASN-GW functionalities,
that is, it implements R3 Reference Point (RP) towards the CSN, R4 reference
point toward other ASN-GWs, and R6 reference point toward AU/BSs. The R8
reference point traffic is transparently relayed between AU/BSs (intra- or
inter-shelf). The ASN-GW mode operates:
» With HA support, that is, the NPU implements Mobile IP services (MIP) Not
supported in the current release.
» Without HA support, that is, the NPU does not implement MIP services
 Transparent mode: In this mode, the NPU transparently relays R6 and R8
reference-point traffic between AU/BSs (intra- or inter-shelf).
