The LLDP protocol is used to exchange information between neighboring devices. An IE

Switch X-200 sends LLDP frames to all ports at regular intervals. The LLDP frames received

from neighboring devices are not forwarded; only the information they contain about

neighboring devices is stored. This information can be read from a central location and used

to identify the network topology.
To structure a network logically, the sending and receipt of LLDP frames can be configured

per port.

Note
The LLDP protocol can be disabled in STEP 7 using the "End of topology discovery"

function.

Note
With the SCALANCE X202-2IRT and X204IRT with a product version lower than or equal to

003, the following port-specific sender addresses are used for LLDP frames:

Port 1: 08:00:06:9D:38:40

Port 2: 08:00:06:9D:38:41

Port 3: 08:00:06:9D:38:42

Port 4: 08:00:06:9D:38:43

With all other X-200 IE switches, MAC addresses are used as the sender address for LLDP

frames that are both device and port-specific.
The MAC address for a specific port is formed by adding the index of this port to the MAC

address of the IE Switch X-200.
