1.4 Typical Applications
5G Fronthaul & Backhaul Convergence
Evolved mobile networks requires high level of synchronization to operate. The required accuracy
level increases as the networks further evolve, reaching the point the expected time error of
nanoseconds is needed in the 5G Fronthaul. The Falcon-RX ability to provide this level of
synchronization, on top of its line rate Ethernet forwarding, makes it the ideal Fronthaul switch.
Additionally, the Falcon-RX can also provide backhaul connection to complete gNodeB units towards
the 5G Core.

IIoT Campus deployment
Modern industrial campuses and factories are being designed to accommodate high level of
automation and mobility in production, which dictates specific requirement for synchronization. In
such environment where, man and machine coexist and work together side by side all actions must
be coordinated and mutually aware. Synchronized packet networks and time sensitive networking
(TSN) are a key element in building these enrolments.

3.2 Console Connection and Configuration
Note: Applicable to R Class series devices.
Figure 3-1: Falcon console connection
To enable basic console connection for initial setup, carry out the following steps:
1. Use an RJ-45-to-DB-9 console cable and insert the RJ-45 connector into the console port on
the front panel. Alternately connect USB-to-USB from PC directly to USB port on Falcon front
panel. Configure the baud rate and character format of the PC or terminal to match these
console port default characteristics:
115200 baud, 8 data bits, 1 stop bit, No parity, None (flow control).
2. Connect the device to a power source and wait until it boots up.
3. The system prompts you to log in.
Default username: moose Default password: 1234.
Note: if you experiment difficulty in the connection, contact Fibrolan support
(International: [e-mail]; North America: Us[email protected])
Initial IP address settings
This first configuration is done via the console; it enables the switch to connect to the IP network.
Once the unit IP address is set via console, the system can be accessed through Web, Telnet, SSH or
any other management options.
Initial IP setup can be implemented by manually setting the IP address Parameters or by an automatic
DHCP setup (if a DHCP server is present).
To assign a new IP address to the device enter the following CLI commands:
➢configure terminal
➢interface vlan 1
➢ip address 192.168.1.90 255.255.255.0
The Falcon R class will initially boot-up with this default IP address: 192.168.1.90/24.

4.1 Overview
This section provides introduction to the R Class series functionality and instructions for
configuration and monitoring.
The configuration and monitoring functionalities can be accessed via various management
interfaces. Sections 4 demonstrates the configuration various functions and setting mainly using the
Web interface. However, any configuration can be implemented using other management interfaces
(CLI, Telnet, and SNMP).
4.2 Frame Processing Overview
This section provides a general description of the Frame Forwarding Process at the R Class series
from the input port toward the output port, as illustrated below.
Figure 4-1: Frame Forwarding Diagram
Input frame flow
Frames received on the input port (MAC layer) are handed to the classifiers in order to classify frames
into different flows (e.g., management frames, specific service/user frames, etc.). Following the
classification, the frames are passed to the Policer. If the Policer is not selected the frames pass
untouched. From the Policer the frames enter the Ingress Queue. Some prioritization algorithms are
used to handle traffic and to avoid buffer overrun and Frame loss.
Output frame flow
The frames, which pass from the Ingress Queue, are transferred to the Egress Queue (8 parallel
queues). The topmost queue handles management frames injected by the CPU, which have super
priority over the other four queues. The remaining queues transfer data frames. At this stage, a
scheduling process is taking place in order to decide which frame will be sent out of the port (out of
the 8 candidate queues). For scheduling either a Strict-Priority or a Weighted Fair Queuing algorithm
is being used. The output of the queue is passed to the Shaper. If the Shaper is not selected the frame
passes untouched. The frames are then passed to the Rewriter. The Rewriter examines the frame
header information and adjusts it if required. From there on the frame is sent to the output port
(MAC layer).
Packet forwarding
Packet forwarding decisions are based on the following criteria:

Falcon R-Class | User Guide
19
•ACL:(Access Control List) The ACL can drop a frame or redirect it to a specific port
•MAC address and VLAN: The standard Ethernet switch forwarding –a frame is forwarded by
searching the learn-table and sending it to the port where the MAC-address + VLAN was learnt.
If the address is not found, or the frame is a broadcast frame it will be sent to all the other
member ports of the VLAN.

Mode
Configure whether the IP stack should act as a Host or a Router. In Host
mode, IP traffic between interfaces will not be routed. In Router mode
traffic is routed between all interfaces.
DNS Server
Controls the DNS name resolution done by the switch. There are four
servers available for configuration, and the index of the server presents
the preference (less index has higher priority) in doing DNS name
resolution. System selects the active DNS server from configuration in
turn, if the preferred server does not respond in five attempts.
The following modes are supported:
•No DNS server: No DNS server will be used.
•Configured IPv4: Explicitly provide the valid IPv4 unicast address of
the DNS Server in dotted decimal notation. Make sure the configured
DNS server could be reachable (e.g., via PING) for activating DNS
service
•Configured IPv6: Explicitly provide the valid IPv6 unicast (except link
