› Extensive CLI capabilities as well as Web-based
management and GUI.
› An open, standards-based architecture to enable
seamless growth and future investments without
proprietary lock-ins. The use of standards also
guarantees complete interoperability with other
network devices.
› Working as a Multi-Customer-Edge (MCE)
Supporting L3 and L2 (Martini, Kompella) MPLS
VPN, which can be extended to support Virtual
Private LAN Service (VPLS).
RESILIENT ARCHITECTURE FOR BUSINESS
CONTINUITY
The S7900E chassis have a high availability design
including passive backplane, redundant/load sharing
fabrics and management modules and redundant
fans and power supplies. All elements in the system
can be hot swapped, minimizing the impact of single
component failure. Changes in network topology due
to device or link failures can lead to disruption of
service for critical business applications. Rapid
recovery from such topology changes is achieved
through features such as Multiple Spanning Tree
Protocol (MSTP), Rapid Spanning Tree Protocol
(RSTP), OSPF Equal Cost Multi Path (ECMP) and
Virtual Router Redundancy Protocol (VRRP).
The S7900E supports IRF technology, an innovative
resilient virtual switching fabric, which enables two
chassis to operate as a single entity for management,
Layer 2 switching and Layer 3 routing. These
capabilities are available even when the two chassis
are in different geographic locations, to support
disaster recovery applications.
The S7900E also supports Resilient Ring Protection
Protocol (RRPP), which allows the creation of fast
recovery rings using standard Ethernet technology.
CONVERGED NETWORK SUPPORT
Real-time applications such as Voice over IP demand
high QoS and different-iated service levels to function
properly. The 3Com S7900E provides robust QoS and
advanced traffic management features, allowing
critical applications to be prioritized and serviced as
the needs of the organization dictate.
Additionally, the S7900E supports the industry-
standard IEEE 802.3af Power over Ethernet (PoE) to
provide both electrical power and network connectivity
to PoE-capable devices such as IP telephones and
wireless access points, making the switches ideal for
large-scale edge deployments. PoE simplifies network
deployments by eliminating the need for separate data
and power infrastructures.
The S7900E supports flexible PoE solutions including
hybrid power which provides power to the switch and
the Ethernet ports to support a range of devices.
EXTENSIVE SECURITY FEATURES
Security is paramount in today’s enterprise. The 3Com
S7900E family has advanced security features including
user and device authentication, policy-driven and
bi-directional hardware-based and wirespeed access
control lists (ACLs), encrypted protocol headers and
system management access. The S7900E supports
IEEE 802.1x Network Login along with RADIUS to
allow user access control. Port, VLAN and MAC
address authentication allow for additional security.
The advanced capabilities of the 3Com S7900E family
can be further extended with included support for
service application modules, which enables direct
integration of advanced Firewall and IPSec VPN, L4-L7
load balancing, network traffic analysis, wireless
access control and management and SSL VPN services.
SCALABLE PERFORMANCE
The S7910E has a 2.4 Tbps backplane for media rate
performances and future expansion. The S7910E with
dual fabrics supports up to 714 Mpps. The wide
selection of modules provide up to 84 10 Gigabit
Ethernet ports and 504 Gigabit Ethernet ports.
Flexible modules combine 10 Gigabit Ethernet and
Gigabit in a single module. The S7900E provides fully
distributed L2 and L3 switching with all processing
local to the module. Standards-based link aggregation
allows aggregating multiple links together as a
“trunk”. Link aggregation is supported across
modules. All fiber-based Gigabit modules support
both 100BASE-FX and 1000BASE-X transceivers.
ENTERPRISE CLASS MANAGEMENT
The S7900E features independent data and control
paths. The dedicated data channel provides high-
speed data switching and packet forwarding, while
a separate management channel provides control,
monitoring, route learning and distribution. A
comprehensive set of management features allows
the S7900E to provide enterprise-wide visibility and
control to IT staff for configuration, network
monitoring and advanced troubleshooting.
