Introduction
A modern business paradigm demands flexibility for a
remote distributed workforce. Distributed organizations
must deploy, configure, manage, monitor and troubleshoot
a growing number of disparate devices in branch sites.
Additionally, the rising demands of high-bandwidth
applications have created a surge in network infrastructure
that supports gigabit and multi-gigabit throughput.
High-performance switch components integrated into an
end-to-end security stack can provide a strong, unified
posture, amplify visibility and control, and enable single-
pane-of-glass (SPOG) management. A unified security
posture enables granular security controls to help identify
and prevent today’s stealthiest and never-before-seen
attacks from compromising your network.
SD-Branch Networks
Switches can play an integrated role in SD-Branch
networks, whether across distributed enterprises, large
campuses, government agency sites or even at designated
home-based office sites. SD-WAN applies software-defined
networking and virtualization to build highly available and
higher-performance WANs. By using low-cost internet
access (broadband, 3G/4G/LTE, fiber, etc.), organizations
can cost-effectively replace expensive WAN connection
technologies such as MPLS. In turn, SD-Branch integrates
SD-WAN with switches, firewalls, wireless, zero-touch
deployment and central management on a single unified
platform. This provides a rapidly scalable solution for
securing distributed branch sites.
Segmenting and Extending Networks
Network segmentation allows security administrators
to create multiple network segments, compartmentalize
internal networks and provide granular secure access.
Functioning on layer 2 (Data Link Layer) of the OSI model, an
effective switch would allow administrators to segregate
traffic based on MAC addresses or VLANs and break up
the large collision domain into smaller ones. Each port on a
switch would support a separate collision domain. Being able
to easily segment devices in the network helps organizations
maintain compliance with regulatory mandates. Segregating
can be accomplished by creating policies or VLANs. For
example, features such as 802.1X authentication help
transactional businesses to maintain PCI-DSS compliance.
By integrating switches with other networking elements,
administrators can also make any wireless network an
extension of the wired network.
The Role of Switches in Today’s Distributed Networks
Why switches are a cornerstone of unified security for SD-Branch.
ABSTRACT
Today’s anywhere/anytime business model demands
secure distributed networking. Switches are a
crucial element to a unified security posture across
distributed enterprises and SD-Branch networks. The
SonicWall Switch Series delivers the core functionality
required in an effective and secure switch solution.

Streamlining Secure Network Management
SPOG management of switches and other integrated
components enables unified control, reporting and analytics,
delivering complete network visibility. By accessing
analytics in real time, administrators can make more
informed decisions.
Zero-Touch Deployment (ZTD) capability can allow
organizations to configure the switch quickly and securely
at new locations without requiring advanced and costly
on-site personnel. Switches should be able to operate
independently or be daisy-chained together to form a single
switch with the port capacity of the combined switches. This
allows administrators to work on one large switch rather
than multiple smaller ones. Some switches offer Power over
Ethernet (PoE), which is ideal for powering on APs, VOIP
phones and IP cameras.
Ensuring Quality of Service
To ensure quality of service (QoS), switches should enable
traffic to be prioritized and avoid excessive broadcast and
multicast traffic. Traffic such as voice and video streaming
could be assigned a higher priority, while non-critical traffic
can be assigned a lower priority. Today’s switch solutions
must also support gigabit and multi-gigabit throughput.
Conclusion
Switches are an integral part of protecting today’s
distributed enterprise in effectively and securely managing
the flow of network traffic. The SonicWall Switch Series
delivers intelligent switching while providing unparalleled
performance, security and manageability. Its unified security
posture makes it ideal for SD-Branch and enterprise
deployments. This enables businesses – big or small – to
undergo digital transformation and keep pace with the
changing network and security landscape.
As a key component of the unified SonicWall SD-Branch
solution, the SonicWall Switch Series tightly integrates
with SonicWall next-generation firewalls (NGFWs), Secure
SD-WAN, Zero Touch Deployment, SonicWave wireless
access points, Capture Client endpoint security and Cloud
App Security, all under Capture Security Center’s single-
pane-of-glass management. When network requirements
change, any of the network functions can be upgraded or
downgraded. With the flexibility that SonicWall Switches
and SD-Branch offer, organizations can be more agile, open
and cloud-centric.
