Function: identifyNetworkDevice()

function identifyNetworkDevice(
   host: string, 
   registries: readonly DeviceEntry[], 
   opts?: SnmpOptions): Promise<
  | EnumeratedNetworkDevice
| undefined>;

Ask one host over SNMP what it is and match the answer against the TCP-capable entries of the given registries.

One GET fetches hrDeviceDescr.1, sysDescr.0 and the serial. hrDeviceDescr.1 is matched first; sysDescr.0 whenever that is absent or matches nothing (other vendors list an interface, not the printer, at hrDeviceIndex 1). Resolves undefined when the host answered but is not in these registries ("not mine"); rejects (TransportTimeoutError / TransportError) when it could not be asked at all (host down, SNMP disabled, wrong community), so drivers can tell the two apart. Never opens a TCP connection.

Parameters

Parameter	Type
host	string
registries	readonly DeviceEntry[]
opts	SnmpOptions

Returns

Promise< | EnumeratedNetworkDevice | undefined>
