LLDP
Configuring frames of the Link Layer Discovery Protocol
On this page, you can configure the handling of frames of the Link Layer Discovery Protocol
(LLDP) per port.
The LLDP protocol is used to exchange information between neighboring devices. An X-200
IE switch 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 X
-200 IE switch.
