X Information about the VLANs of which the port is a member (VLAN ID and
VLAN name).
A network management station can call up this information from a device with
LLDP activated. This information enables the network management station
to map the topology of the network.
To exchange information, LLDP uses an IEEE MAC address which devices
do not usually send. For this reason, devices without LLDP support discard
LLDP packets. Thus a non-LLDP-capable device between two LLDP-capa-
ble devices prevents LLDP information exchange between these two devic-
es. To get around this, Pilz devices send and receive additional LLDP
packets with the Pilz Multicast MAC address 01:80:63:2F:FF:0B. Pilz devices
with the LLDP function are thus also able to exchange LLDP information with
each other via devices that are not LLDP-capable.
The Management Information Base (MIB) of an LLDP-capable Pilz device
holds the LLDP information in the LLDP MIB and in the private hmLLDP.
