LLDP defines several operational parameters that control the protocol behaviour (see IEEE Std 802.1AB2016, 10.5.1). These parameter definitions apply to all external ports of a UAFX Station.

NOTE According to IEEE Std 802.1AB2016, 9.1.1 c), changes to the local system that impact information exchanged via LLDP immediately trigger the transmission of an LLDPDU to communicate the local changes as quickly as possible to any neighbouring systems.

A UAFX Station shall support LLDP transmit mode (adminStatus enabledTxOnly) on an external End Station Component port and may support transmit and receive mode (adminStatus enabledRxTx) on that port (see IEEE Std 802.1AB-2016, 10.5.1).

A UAFX Station shall support LLDP transmit and receive mode (adminStatus enabledRxTx) on an external Bridge Component port (see IEEE Std 802.1AB-2016, 10.5.1).
