1. INTRODUCTION
≡1 Introduction
The TTE-Switch A664 Lab v2.0 supports laboratory testing efforts of TTEthernet.
TTEthernet is a fault-tolerant real-time communication protocol for safety-related systems that makes it
possible to conveniently configure the deterministic processing of critical Ethernet traffic (time-triggered,
ARINC 664 P7 [2]) and non-critical, standard Ethernet traffic (IEEE 802.3 [6]) in one physical infrastructure.
Switching function
The TTE-Switch A664 Lab v2.0 is a high-performance deterministic Ethernet switch that makes it possible
to implement critical network-centric applications and process packets on all its 24 ports with full-line
speeds, operating in full-duplex mode:
• 6 x triple-speed 10/100/1000 Mbit/s ports, and
• 18 x 10/100 Mbit/s ports
One additional port is available for traffic mirroring. The TTE-Switch A664 Lab v2.0 has built-in mecha-
nisms for traffic policing and fault isolation.
Virtual links and protocol support
The TTE-Switch A664 Lab v2.0 allows configuring up to 4096 virtual links (VLs). Virtual links can be
configured with 8 priorities and a bandwidth allocation gap (BAG) of 0.01 ms to 1310.71 ms. The net-
work configuration is stored in the non-volatile memory of the switch (256 Mbit). It is optionally possible
to configure IEEE 802.1Q VLANs. Profiled IP/UDP, redundancy management, and traffic shaping are
implemented in hardware.
Data loading and diagnosis
The built-in management module runs on a separate CPU and allows for data loading and the querying
of the network status via SNMP. Data loading is done according to ARINC 615A-3/TFTP and ARINC 665-
loadable software parts.

2.3 Functional features
• Full line speed switching capability
• The switch supports partitioning between three traffic classes on each port:
a) Rate-constrained traffic (full compliance with ARINC 664 part 7 [2]),
b) Time-triggered traffic (SAE AS 6802 [7]), and
c) Best-effort traffic (IEEE 802.3-2005 [6])
• 32 MB of memory
• 256 Mbit Flash memory for storing switch configurations
• Application CPU for management functions
• Configuration data programmable via ARINC 615A [1]/TFTP
• Built-in self-tests (BISTs) for health monitoring
• Monitoring faulty/healthy switch state through SNMP
• Pin programming support
• External adapter with 12 dip switches for pin programming (including parity) and mode selection.
Supported network standards
• The switch forwards best-effort traffic in compliance with IEEE 802.3-2005 [6] (switching). The switch
has a maximum internal non-blocking port-to-port latency of 2 µs for 1 Gbit/s ports, 20 µs for 100 Mbit/s
ports, and 200 µs for 10 Mbit/s ports. This is for a frame size of 1518 bytes, sent as best-effort (BE)
traffic. The switch allows limiting best-effort traffic for each ingress and egress port.
• The switch forwards VLAN-tagged frames according to IEEE 802.1Q [4] (VLAN core capabilities).
NOTE The switch does not implement port-based VLANs (edge switch). This means that the switch cannot
add VLAN tags to frames coming in on a specific port. The switch does not implement content-based
VLANs (e.g., based on IP addresses or TCP/UDP ports).
The switch supports static VLAN routing according to a configuration table. VLAN frames will be
accepted and routed only to the configured switch ports. VLANs are processed with a higher priority
than BE frames without a VLAN tag. The switch routes VLAN frames according to the priority specified
in the VLAN field. Frames with the same VLAN priority are processed on the basis of the incoming
switch port number. VLAN frames with the same priority are handled in a similar way as RC frames
with the same priority. Frames from Port 1 have priority over frames from Port 2. The switch can
store VLAN frames in a separated buffer space. Depending on the respective configuration, BE and
VLAN frames cannot share the same buffer space. Frames that contain a VLAN tag that is not in
the list of the configured VLAN IDs are routed according to a default VLAN route. A default VLAN

3.2.3 MIRROR port
The TTE-Switch A664 Lab v2.0 has a 10/100/1000 Mbit/s mirror port that can be used to forward selected
traffic to a dedicated monitoring end system (e.g. a PC running Wireshark).
For monitoring, an end system must be configured in the network description, or the mirror port must be
configured via the RS-232 interface. Configuring the mirror port via the RS-232 interface is only possible
in SHOP mode.
NOTE For CLI commands to enable hardware mirroring, see Section 7.5.3 on page 33.
3.2.4 Ethernet ports
Figure 7: The Ethernet ports of the TTE-Switch A664 Lab v2.0
The switch has 24 Ethernet ports, numbered PORT1 to PORT24. Ethernet ports PORT1 and PORT2
are special as they can be used either via SFP or RJ45. For each of these two ports, only one of the
connectors can be used at a time as both the SFP and RJ45 interface connect to the same physical layer.
The ports are configured as follows:
Port Description
1 … 2 General-purpose SFP and RJ45 Ethernet ports:
fiber medium – 100Base-FX/1000Base-X
copper medium – 10Base-T/100Base-TX/1000Base-T
3 … 6 General-purpose RJ45 Ethernet ports:
copper medium – 10Base-T/100Base-TX/1000Base-T
7 … 24 General-purpose RJ45 Ethernet ports:
copper medium – 10Base-T/100Base-TX
Table 4: Ethernet ports of the TTE-Switch A664 Lab v2.0
NOTE Hot-plugging of SFP modules (i.e. inserting a module during run-time) is not supported by the switch
and requires a reset to configure the module properly.
There are two LEDs per port integrated in the connector, a green Link LED and a yellow Activity LED.
Port LED Description
The Link LED is solid green when a link is established with the connected end system.
The Activity LED flashes yellow when communication activity is detected (frame transmission
or frame reception).

4. GETTING STARTED
≡4 Getting started
This section describes the sequence of steps to get started with the TTE-Switch A664 Lab v2.0.
1. Make sure the switch is connected to a power outlet and switched off.
2. Connect an RS-232 connector to the RS-232 serial interface on the back panel of the switch (see
also Appendix B).
The settings for serial communication are: 19200 baud, 8 data bits, 1 stop bit, no parity, no handshake.
3. Connect the DB-25P configuration plug to the DB-25S CONFIG interface on the front panel of the
switch.
4. On the DB-25P configuration plug, use the following dip switch positions to load the default configu-
ration of Position 0:
Dip Switch Position
Con_Sel_0 OFF
Con_Sel_1 ON
Con_Sel_2 ON
Con_Sel_3 ON
Con_Sel_4 ON
Con_Sel_5 ON
Shop-Mode OFF
Maintenance OFF
Grnd-Mode ON
5. Turn on the power switch.
• On start-up, all status LEDs are briefly turned on, which changes during the switch start-up
sequence (see Table 1on page 11).
• When the switch has successfully finished start-up, the POWER LED and the STATUS LED are
solid green. As the switch default configuration was selected for start-up, the DEF. CONF LED
is solid green as well.
• See Appendix Bfor the serial terminal output during start-up.
In the Operational state the switch provides information via SNMP. In SHOP mode, it is possible to
retrieve more detailed information via serial terminal.
6. Connect a host PC directly to one of the 24 front-panel ports using a standard Cat5 or Cat5e patch
cable.
• Set the IP address of the host PC to the same subnet as the switch, for example to 10.10.10.20.
• Set the subnet mask of the host PC to 255.255.255.0.
• Set the transmission speed to 100 Mbps Full Duplex and make sure auto-negotiation is acti-
vated.
7. To verify that the switch is operational, open the CLI window, type ping 10.10.10.10 and press
Enter . If no data packet was lost, the ping was successful.
