This holds the network address to use for reaching this component directly when chCompAccessPolicy is set to other, meaning the component isn't accessed through the chassis's standard SNMP path at all; in every other access-policy case, this reads back as 0.0.0.0. Admins would set this when a component actually has its own independent management address that must be contacted separately. For example, a component with its own embedded management processor and IP stack would have chCompNetAdr populated with that processor's own address so management traffic can be directed straight to it.
