Abstract
A network device with wireless access point capabilities selectively captures PDUs detected on an instrumented interface(s) to capture those of one or more types/subtypes 'of interest.' PDU types/subtypes that network device interface(s) has been instrumented to treat as “of interest” include those transmitted during a device's initial network activity during startup or attempted establishment of a wireless network connection. The interface(s) instrumented for targeted PDU capture can include wireless and/or wired (e.g., Ethernet) interfaces that are received on raw sockets so that each header type of a captured PDU is written to the PDU capture file. Prior to upload of a PDU capture file to a system from which it can be retrieved for analysis, the network device adds network metadata to the file based on context of the environment in which the network device operates. The network metadata can include IP address and/or network topology information determined at runtime.
