Systems for communicating network device information between network devices. A communication is established between a first network device and a second network device according to a link layer discovery protocol (LLDP). An LLDP advertisement message is output in the communication from the second network device to the first network device. The first network device determines whether the second network device processes fragmented packets by searching the LLDP advertisement message for a fragmentation time length value (TLV) field. The second network device outputs to the first network device a plurality of packet fragments in response to a determination that the LLDP advertisement message includes the fragmentation TLV field.
