Node Protection Key Parameter

Parameter:

Node Protection Key

Path: Configuration Manager > Protocols > IP > IP Security > Manual Security

Associations (SAs)

Configuration Manager > Protocols > IP > IKE

Default:

None

Options:

An 8-byte value

Function:

Used as a cryptographic key for protecting sensitive MIB objects. The NPK

value is stored in nonvolatile random access memory (NVRAM). The IPsec

software performs a hash of the NPK value, which it places in a special MIB

attribute. The NPK value stored in NVRAM is unique to the router. It is used to

encrypt the cipher and integrity keys before they are stored in the router MIB.

Instructions:

Enter a 16-digit hexadecimal value. (Enter the prefix 0x before the digits.)

MIB Object ID:

None
