METHODS
- new
-
Object constructor. You can pass attributes that will overwrite default ones. Default values:
protocolType: NP_CDP_ADDRESS_PROTOCOL_TYPE_NLPID
protocolLength: NP_CDP_ADDRESS_PROTOCOL_LENGTH_NLPID
protocol: NP_CDP_ADDRESS_PROTOCOL_IP
addressLength: NP_CDP_ADDRESS_ADDRESS_LENGTH_IP
address: '127.0.0.1'
- pack
-
Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.
- unpack
-
Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.
