Cisco 2900 Series
Wireless and Mobility Services
Wireless LAN/WAN
The Cisco Integrated Services Routers supporting
the Cisco Unified Wireless Architecture enable
deployment of secure, manageable wireless LANs
(WLANs) optimized for remote sites and branch
offices, including fast secure mobility, survivable
authentication, and simplified management. The
Cisco Wireless LAN Controller Module on the
Cisco 2900 Series allows small and medium-sized
businesses (SMBs) and enterprise branch offices
to cost-effectively deploy and manage secure
WLANs. Cisco Wireless LAN Controllers work in
conjunction with Cisco lightweight access points
and the Cisco Wireless Control System (WCS) to
provide system-wide WLAN functions, managing
up to 6, 12, and 25 access points.
Wireless WAN
Cisco third-generation (3G) wireless WAN (WWAN)
modules combine traditional enterprise router
functions, such as remote management, advanced
IP services such as voice over IP (VoIP), and
security, with mobility capabilities of 3G WAN
access. Using high-speed 3G wireless networks,
routers can replace or complement existing
landline infrastructure, such as dialup, Frame
Relay, and ISDN. Cisco 3G solutions support 3G
standards High-Speed Packet Access (HSPA)
and Evolution Data Only/Evolution Data Optimized
(EVDO) providing you with a true multipath WAN
backup and the ability to rapidly deploy primary
WAN connectivity. For more information about 3G
solutions on Cisco Integrated Services Routers,

Integrated LAN Switching
The Cisco 2900 Integrated Services Routers (Cisco
2911 through Cisco 2951) support the new Cisco
Enhanced EtherSwitch ® Service Modules, which
greatly expand router capabilities by integrating
industry-leading Layer 2 or Layer 3 switching with
feature sets identical to those found in the Cisco
Catalyst 2960 and Catalyst 3650-E Series Switches
performing local line-rate switching and routing.
The new Cisco Enhanced EtherSwitch Service
Modules take advantage of the increased power
capabilities on the Cisco 2900 ISRs. Additionally,
the Cisco Enhanced EtherSwitch modules
enable the newest Cisco power initiatives, Cisco
EnergyWise, Cisco Enhanced Power over Ethernet
(ePoE), per-port PoE power monitoring, and RPS-
98
enabled PoE boost. These technologies allow you
to meet increased endpoint power requirements
without increasing the total power consumption of
the branch.
Application Services
As organizations continue to centralize and
consolidate their branch-office IT infrastructure
in an effort to reduce cost and complexity, they
are challenged to provide an excellent user
experience, ensure continuous service availability,
and deliver business-relevant applications when
and where they are needed. To address these
challenges, the Cisco 2900 Series provides the
capability to host Cisco, third-party, and custom
applications on a portfolio of high-performance
Cisco Services Ready Engine (SRE) modules that
transparently integrate into the router. The modules
have their own processors, storage, network
interfaces, and memory that operate independently
of the host router resources, helping to ensure
maximum concurrent routing and application
performance while reducing physical space
requirements, lowering power consumption, and
consolidating management.
Application Acceleration
The Cisco 2900 Series seamlessly combines
industry leading security, IOS based traffic control
and visibility, with Cisco application acceleration
solutions. Cisco IOS Software features such
as NBAR, IP SLA, and NetFlow provide visibility
and monitoring of traffic patterns and application
performance while IOS features such as QoS,
ACLs, and PfR intelligently control the traffic to
maximize the quality of the user experience and
employee productivity. The user experience
can be further enhanced through the addition
of a Cisco WAAS Network Module which can be
used to securely provide more advanced WAN
optimization techniques such as TCP optimization,
caching, compression, and application acceleration.
Cisco Integrated Services Routers combined with
Cisco WAAS Network Modules, provide optimal
performance for applications delivered from a
central data center to branch-office users. The
solution allows you to consolidate costly server,
storage, and backup infrastructure into data centers
while maintaining LAN-like service levels for remote
users.

Cisco Unified Computing System
Express
The Cisco Services Ready Engine solution is
available in a Service Module and Internal Service
Module (ISM) form-factor. The Service Module
hardware offers up to a seven times performance
improvement over the previous-generation
Network Modules and provides a multi-core x86-64
processor. The SRE modules also support up to 1
terabyte of storage, RAID configurations, hardware-
assisted virtualization and cryptography options.
The Cisco SRE module enables on-demand
provisioning of branch-office applications on
the Cisco 2900 Series platforms so that you can
deploy the right application, at the right time, in the
right place. The hardware and software decoupling
provided by the service-ready deployment model
enables applications to be provisioned on the
module at the time of its installation or remotely
anytime thereafter. Supported solutions include
Cisco Wide Area Application Services (WAAS),
Cisco Unity Express, Cisco Application Extension
Platform (AXP), Cisco Wireless LAN Controller
(WLC), Cisco Video Surveillance, and other
applications under development. The Service
Ready Engine enables organizations of various
sizes to future-proof their network by allowing them
to quickly deploy new branch-office applications
without deploying new hardware, reducing the cost
of rolling out branch-office services.

Managing Your Integrated Services
Routers
Network management applications are instrumental
in lowering operating expenses (OpEx) while
improving network availability by simplifying
and automating many of the day-to-day tasks
associated with managing an end-to-end network.
Day-one device support provides immediate
manageability support for the Integrated Services
Router, enabling quick and easy deployment,
monitoring, and troubleshooting from Cisco and
third-party applications.
Organizations rely on Cisco, third-party, and
in-house developed network management
applications to achieve their OpEx and productivity
goals. Underpinning those applications are the
embedded management features available
in every Integrated Services Router. The new
Integrated Services Routers continue a tradition
of broad and deep manageability features such
as IP service-level agreement (IP SLA), Cisco IOS
Embedded Event Manager (EEM), and NetFlow
which allow you to know the status of your network
at all times. These features, along with Simple
Network Management Protocol (SNMP) and
syslog, enable your organization's management
applications.
