VLAN (Port-Based VLAN) 
For configuring the use of port-based VLAN.  
Should VLAN be supported, port-based VLAN should be off to enable each port to 
communicate with the other switch ports. 
For each port on one switch, the user can define which other ports of the switch received 
Ethernet frames may be sent to.  
The table in the VLAN tab contains entries through which the connection between two ports can 
be set as active or inactive. 
Default setting: All connection between ports active 
 
LLDP 
With LLDP (Link Layer Discovery Protocol), information such as MAC address, device name, 
port number is sent per multicast in periodic intervals via the own device and is received from 
the neighboring devices.  
LLDP uses the following values depending on whether PROFINET is configured on the 
communication module: 
PROFINET on the COM module 
Table 19:  Values for LLDP 
The processor and communication modules support LLDP on the Eth1, Eth2, Eth3 and Eth4 
ports.  
The following parameters define how a given port should work: 
LLDP is disabled on this port. 
LLDP sends LLDP Ethernet frames, received 
LLDP Ethernet frames are deleted without being 
processed. 
LLDP sends no LLDP Ethernet frames, but 
received LLDP Ethernet frames are processed. 
LLDP sends and processes received LLDP 
Ethernet frames. 
Default setting: Send/Receive
