4.3 Operating principle
The TBEN-L…-SE-M2 is used to build industrial Ethernet networks according to IEEE 802.3. and
connects up to ten network segments. The switch controls the data traffic within a network
domain and forwards data telegrams specifically to connected devices. A switch can send and
receive messages simultaneously.
The switch can manage two different network zones (LAN and WAN). All Ethernet ports that are
assigned to one of the two zones are switched with each other.
In the delivery state, the device behaves as a layer 2 switch. Layer 3 functions can be activated
optionally.

V02.00 | 2021/11 11
4.4 Functions and operating modes
4.4.1 SNMP agent
The switch supports SNMP (Simple Network Management Protocol) V1, V2c and V3. The SNMP
function of the device can be configured via the web server.
4.4.2 Neighborhood detection via LLDP (Link Layer Discovery Protocol)
The switch uses the LLDP protocol for neighborhood detection. Like all LLDP-capable network
devices, the switch sends information about itself and stores information received from its
neighbors. This information is queried by a network management system via the Simple Net-
work Management Protocol (SNMP) and used for topology detection.
4.4.3 Prioritization/classification of data packets via QoS
The function QoS (Quality of Service) enables the prioritization (via PCP) or classification (via
DSCP) of data telegrams.
nPCP (Priority Code Point)
This function prevents time-critical data traffic from being disrupted by less time-critical data
traffic in heavily loaded networks. By assigning high priorities for time-critical data and low
priorities for less time-critical data, an optimal data flow for high-priority data is achieved.
Frames to be transmitted are divided into priority classes from 0 to 7. 0 is used for frames
that are not assigned a specific priority.
nDSCP (Differentiated Services Codepoint)
DDSCPs are used to classify data packets. A DSCP (0...63) specifies a forwarding behavior for
a data packet, i.e. it determines how a packet is handled.
4.4.4 DHCP
The switch supports the following DHCP options:
nDHCP server
nDHCP client
nDHCP server option 82, port-based IP address assignment
4.4.5 Network redundancy
The switch supports network redundancy via STP and RSTP.
Network redundancy via STP (Spanning Tree Protocol)
STP is an open protocol for setting up closed, loop-free networks with redundant paths via so-
called spanning trees. In the event of a node failure or a line break in the network, the data is re-
directed via a backup path. The switching times for STP are usually between 20 and 30 seconds.
Network redundancy via RSTP (Rapid Spanning Tree Protocol)
RSTP is a further development of the STP with shorter switching times of 1 to 10 seconds. With
RSTP on network participant acts as root. Unnecessary ports of network participants that lead
to network loops and thus to unnecessary data traffic are deactivated and only activated in the
event of an error to form a backup path.
Network redundancy via MSTP (Multiple Spanning Tree Protocol)
MSTP is an extension of the RSTP. MSTP enables different instances of the Spanning Tree in
conjunction with Virtual Local Area Networks (VLANs). For a VLAN or a group of VLANs, inde-
pendent STP instances can be formed that use their own spanning trees within a LAN.

12 Hans Turck GmbH & Co. KG | T [phone] | F [phone] | [email protected] | www.turck.com
4.4.6 Routing
Routing is used to forward data packets between networks with different IP address ranges.
Several routing rules can be defined in the switch for data transfer between the configurable
LAN and WAN network zones.
NOTE
IP forwarding (forwarding of data packets between networks with different IP ad-
dress ranges) must be activated.
4.4.7 Firewall
The switch firewall offers the possibility to set up rules for incoming and outgoing data packets
as well as forwarding rules for data packets. The rules can be defined network-wide or IP-ad-
dress-based and apply to all data packets or only to UDP-based or TCP-based packets.
4.4.8 NAT (Network Address Translation)
If IP forwarding (forwarding of data packets between networks with different IP address ranges)
is activated, IP addresses of one network are translated into IP addresses of another network.
Example: IP addresses of network participants of an internal network are assigned to IP ad-
dresses of an external network.
4.4.9 Mirroring – mirroring switch ports
With the Mirroring function, data present on one port of the switch can be mirrored to another
port. Only incoming, only outgoing or both types of data packets can be mirrored.
4.4.10 IGMP (Internet Group Management Protocol)
IGMP is the protocol for IP multicast applications in TCP/IP networks and is used to organize
multicast groups. The switch can log on or off by sending IGMP messages to a router to receive
multicast telegrams.
