USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
1 INTRODUCTION
1.1 GENERAL
The SW3-L3 is a Gigabit/Fast Ethernet switch/router specially designed to perform
switching functions (L2) and IPv4 routing functions (L3).
Level 2 capabilities enable deployment of big scale LANs when the main requirements are:
Port density,
switching performance, and
logical complexity.
Level 3 capabilities offer:
Routing functionality between two or more configured VLANs, with each VLAN being
made up of a set of local ports (Ethernet and Gigabit Ethernet).
The routing process is performed in hardware, that is, at wire speed for unicast traffic.
The SW3-L3 supports the SNMPv1, SNMPv2c and SNMPv3 management protocols, the
RIPv1, RIPv2, OSPFv2 and BGPv4 routing protocols, the VRRP redundancy protocol, as
well as other protocols and services such as LLDP, GARP/GMRP, IGMP, DHCP,
NTP/SNTP, TACACS+ and RADIUS.
As a level 2 switch, SW3-L3 brings the necessary capabilities to implement the automation
of electrical substations according to the IEC 61850 standard.
The SW3-L3 supports standard IEEE 1588v2 clock synchronization (Precision Time
Protocol), in Transparent Clock (TC) P2P mode.
The SW3-L3 can be managed locally and remotely, through a local console, Telnet server
and SSH server, or through a built-in web server, HTTP or HTTPS.
The SW3-L3 stores an internal backup copy of the application software so, in case of some
incidence, the operation of the equipment is guaranteed by running the backup software.

USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
1.2 MAIN CHARACTERISTICS
Some of the SW3-L3 most important features are described below.
❖Grouping of services and architectures.
Services may be grouped and discriminated, some not being accessible with others,
through the configuration of different VLANs.
Each VLAN is different from the others thanks to a specific identifier, called VID, which is
included in the VLAN tag and specified in the standard IEEE 802.1q. It permits several
VLANs to share resources, either switching devices such as the SW3-L3, or links
between switching units, guaranteeing that each VLAN traffic will remain isolated from the
others.
The standard 802.1q admits three types of frames: untagged frames, tagged frames with
the VLAN (VID) identifier and the priority (tagged) or only the priority (priority tagged,
VLAN = 0).
The SW3-L3 may adapt to different network architectures, such as: star, double star, ring,
double ring, and linked rings.

USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
❖Link Aggregation by LAG function.
The Link Aggregation Group (LAG) function allows grouping several links into a single
aggregated link identifier. FIGURE 3 illustrates an example of link aggregation. From the
point of view of the STP/RSTP protocol, the connection entity is the LAG group identifier.
In this way, the different links that are part of the LAG are not handled individually and are
not considered a loop, and thus it provides the aggregated bandwidth.
Link aggregation can be created for any of the planned interface functions: user (edge,
untag), inter-switch link (trunk or native) and those associated to the Q-in-Q functionality
(access and core). Once the LAG is selected, the set of parameters of the interface
selected as Leader determines the behaviour of the group.
❖Q-in-Q operation.
The SW3-L3 includes two functions that provide Q-in-Q operation (double-tagged). In this
operation mode, the frames include the original tag (C-TAG), either generated by the
client equipment or assigned by the switch itself at the moment is received, and a second
tag, the tag of the provider (S-TAG), which will be the tag used in the network of the
service provider.
The 802.1Q tunnels are a useful tool to reuse the identification VID values of the VLAN,
or for transiting data over third-party networks.

GIGABIT/FAST ETHERNET SWITCH/ROUTER TYPE SW3-L3 10/180
USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
❖Advanced RSTP implementation.
The SW3-L3 not only complies with the STP and RSTP protocols for resolving loops in
the network and operation in rings, but it also exceeds the recovery times obtained
through said protocols. Thus, the SW3-L3 guarantees recovery times lower than 4 ms per
link via the RSTP standard in case of failure.
❖Critical services and security.
The different services have their level of importance. For example, sending orders to
open a switch has priority over the traffic from a telephone connection. The SW3-L3 has
Quality of Service (QoS), which identifies critical services, guaranteeing that all traffic
receives the appropriate priority.
On the other hand, the SW3-L3 implements different security features that prevent
unauthorized access to the traffic system, such as: port disabling, traffic restriction
according to MAC addresses, authentication protocols (TACACS+, RADIUS), etc.
❖Broadcast traffic limitation.
In order to avoid the network flooding, the SW3-L3 selects maximum volume limits for
different combinations of broadcast, multicast, and flooding messages, in each one of
their ports.
❖Multicast traffic.
The SW3-L3 has two protocols for adapting the multicast traffic to the desired interfaces.
The protocols are:
oGARP/GMRP (IEEE 802.1D 2004). The GMRP clients request to the SW3-L3
the selective transmission of the multicast traffic desired by each of them.
oIGMP. The SW3-L3 manages multicast traffic based on the IGMP messages
exchanged by the client devices and the multicast routers (IGMP Snooping). To
be operative, the GARP/GMRP protocol must be INACTIVE.
The SW3-L3 also selects the multicast flows in an explicit and manual way (static
configuration).
❖Port mirroring.
The SW3-L3 resends traffic copies of one or more ports to another one, the monitoring
port, being able to select incoming or outgoing traffic copies in each monitored port in an
independent manner.

GIGABIT/FAST ETHERNET SWITCH/ROUTER TYPE SW3-L3 11/180
USER GUIDE - M0SW3M1902Iv07 - V06 February 2019
❖IP routing.
The SW3-L3 is an IPv4 router for unicast traffic. The data for the routing function may
have two sources; static data of a permanent nature (configured by the user) and
dynamic data, obtained by the equipment itself through executing the standard routing
protocols: RIP, OSPF and BGP. All these protocols can be active simultaneously.
In addition to routing function, the equipment has the VRRP redundancy protocol, so that
it may be part of one or various virtual routers.
❖Traffic filtering.
All traffic processed by the SW3-L3 takes into account the filtering rules that the user
might configure so that routing operations are subject to restrictions as: input interface,
output interface (from the routing table), IP address of origin network, IP address of
destination network or the service (tcp, udp), the latter supports the use of a range of
ports, both destination and origin.
Filtering rules admit conditions in many fields.
1.3 EQUIPMENT COMPOSITION
The SW3-L3 is provided in a 19" shelf that is 1 standard unit (s.u.) in height, prepared for
rack mounting.
It includes a serial maintenance interface (DCE mode) and an I/O connector (see section
