A powerline network consists of one or more powerline devices that share a common NMK. One device on the network is in charge of the network and known as the Central Coordinator (CCo). All other devices on that network are known as stations (STA). Each device maintains internal information about the network to which it belongs. You can view that information at any time.

# int6k  -mieth3
eth3 00:B0:52:00:00:01 Fetch Network Information
eth3 00:B0:52:00:00:BB Found 1 Network(s)

	network->NID = 77:23:0D:91:06:6E
	network->SNID = 6
	network->TEI = 1
	network->ROLE = 0x02 (CCO)
	network->CCO_DA = 00:B0:52:00:00:BB
	network->CCO_TEI = 1
	network->STATIONS = 1

		station->DA = 00:B0:52:00:00:AA
		station->TEI = 2
		station->BDA = FF:FF:FF:FF:FF:FF
		station->AvgPHYDR_TX = 0 mbps
		station->AvgPHYDR_RX = 0 mbps

The example above prompts the local device on interface eth3 for network membership (-m) information. Device 00:B0:52:00:00:BB responded and reported that it belongs to one powerline network. The first block of information identifies the network CCo. The second block of information identifies a network STA. This second block will repeat when multiple stations are present. Each device on the network has a unique Terminal Equipment Identifier (TEI) within the network. The average PHY rates show the data rates between the reporting device and each STA. In this cases there has been no traffic.
