The C-Series product line provides high port density in a 1U footprint and
is environmentally friendly by design. By maximizing port density within a
given amount of rack space, the C3 minimizes its cooling requirements.
The C3’s overall electrical requirement is further reduced by a low current
draw and an extreme tolerance for high environmental temperatures. A
highly-scalable architecture and a lifetime warranty ensures that a C3
network investment will sustain a secure, feature-rich and cost-effective
network well into the future.

Reliability and Availability
The C3 design incorporates redundancy and failure protection
mechanisms complete with automatic failover and recovery capabilities
to provide a reliable network. An integral power supply is the primary
source of power for the C3 and complete power redundancy is provided
by an optional external power supply. In addition to the standard version
of the C3, there is also a redundant Power over Ethernet (PoE) version of
the C3 which supports network devices that require external power such
as wireless access points, VoIP phones, and network cameras. A virtual
switch can be created by interconnecting as many as 8 C3s in a single
stack, which can be managed via a single IP address with redundant
management connections. The C3’s closed-loop stacking (CLS) capability
utilizes bi-directional switch interconnects to maintain connectivity
within the virtual switch despite any physical switch-level failure. Up to 8
Ethernet ports can be grouped together to create a multi-link aggregation
group (LAG). A LAG’s Ethernet ports can be collocated on a single C3
or they can be distributed across multiple C3s within a stack to prevent
a switch-level failure from disrupting data communications. The C3
also supports equal cost multipath protocol (ECMP) and virtual router
redundancy protocol (VRRP) to strengthen its ability to quickly recover
from a network failure.

Advanced Quality of Service
Robust QoS features enable strong support for integrated multimedia
networks, including VoIP and video, as well as all types of data-intensive
applications. The C3 provides highly customizable Layer 2/3/4 packet
classification capabilities, which can be based upon physical port ID,
MAC address, IP subnet, IP address, IP protocol type, IP Type of Service
(ToS), differentiated services code point (DSCP), and TCP/UDP port. The
C3 provides 8 hardware-based priority queues per Ethernet port, which
work together with its packet classification capabilities to support a suite
of differentiated services with as many as 8 distinct priority levels. The
strict and weighted round robin queuing algorithms ensure that mission-
critical applications receive prioritized access to network resources.

Security
The C3 provides a secure network by utilizing its authentication and
security features, which can be applied at the port level or at the user
level. Making use of the NMS Policy Manager or a standard CLI, the
Enterasys role-based architecture enables a network administrator to
define distinct roles or profiles that represent operational groups within
a business (e.g., employee, executive, guest, etc). Multiple users/
devices per port can be authenticated via IEEE 802.1X, MAC address,
or web authentication, and then assigned a pre-defined operational
role. Administrators can easily transition from RFC 3580 and complex
ACL deployments to the Enterasys role-based policy framework in a
seamless fashion, without the need to make changes to their RADIUS
infrastructure (e.g., adding filter-ID). In addition, the C3 also supports
access control lists (ACLs) for supplementary network security. Network
operations can be easily tailored to meet business-oriented requirements
by providing each role with individualized access to network services and
applications (e.g., a guest should have different network access privileges
than an employee).

Investment Protection
The C3 is a cost-effective, feature-rich, stackable switch that provides
a broad set of features today and will continue to deliver benefits well
into the future. Customers can grow and/or enhance their networks while
protecting their investment by adding C3s into existing C-Series networks
and/or stacks. When multiple C3s are stacked together, each switch in
the stack assumes the feature set that is common to all switches in the
stack to ensure operational compatibility. All C-Series products include
a lifetime warranty that continues for 5 years after the date of product
discontinuation. For more information regarding warranty terms and
conditions please go to

Performance & Scalability
The C3 provides scalable, wire-rate performance in support of the
bandwidth-intensive and delay-sensitive requirements of today’s
demanding applications. Along with a switch capacity of 192 Gbps, the
C3 provides up to 48 10/100/1000 Ethernet ports as well as 2 10GE
uplink ports. Leveraging the C3’s wire-rate stacking capability, as many
as 8 C3s (both 24-port and 48-port combinations) can be interconnected
in a single stack to create a virtual switch that provides 1.54 Tbps of
capacity and up to 384 10/100/1000 Ethernet ports as well as 16 10GE
uplink ports. The C3 supports hundreds of distinct policies (rules) that
enable granular definition of network access capabilities for each role, thus
aligning network resource utilization with business goals and priorities.
