The Cisco® 7301 Series Router is a
compact, high-performance
single-rack-unit (1RU) router
coupled with a broad set of
interfaces and Cisco IOS® Software
features, which makes it ideal for
both service providers and
enterprise applications.
As part of the industry-leading
Cisco 7000 Series routers, the
Cisco 7301 packs high
performance in a space- and
power-efficient chassis that
includes a single Cisco 7000
Series port adapter slot, three
onboard Gigabit Ethernet (copper
or optical) or Fast Ethernet
ports, and new high-speed bus
technologies. The key features
of the Cisco 7301 Router are:
， Three times the performance
increase over existing 1RU
routers
， Compact, power-efficient 1RU
form factor
， Single Cisco 7000 Series port
adapter slot
， Complete Cisco IOS Software
feature support
， Three onboard Gigabit Ethernet
(copper or optical) or Fast
Ethernet ports
， Pluggable Gigabit Ethernet
optics (Small Form-Factor
Pluggable [SFP] optics)
， Up to 1 GB of available DRAM,
supporting up to 1 million
routes
， Up to 256 MB of removable
compact Flash memory
， Front-to-back airflow and
single-sided management
The Cisco 7301 delivers a full
suite of Cisco IOS Software
services for managing network
security, allocating quality of
service (QoS) among applications
and users, and providing
value-added services such as
NetFlow accounting and
encryption. QoS applications
such as Committed Access Rate
(CAR), Weighted Random Early
Detection (WRED), and Weighted
Fair Queuing (WFQ) can be
flexibly applied to provide
precedence across IP addresses,
applications, or specific users
with a high level of
granularity.
With its combination of scalable
performance, compact
architecture, high density, and
low price per port, the Cisco
7301 is ideally suited for a
variety of key applications
within both the service provider
and enterprise markets.
SERVICE PROVIDER APPLICATIONS
The Cisco 7301 is targeted
towards five principal
application areas within a
service provider network:
， Broadband aggregation: PTA/LAC
or LNS/TS aggregation router
capable of handling up to 16,000
simultaneous sessions and
allowing for a pay-as-you-grow
"rack and stack" architecture.
， IPv6 gateway: Linking between
an IPv4 network and an IPv6
network, including IPv6 VPN
architectures.
， Managed services: High-end
customer premises equipment (CPE) or Multiprotocol Label
Switching-customer edge (MPLS-CE) devices due to its
high-performance, feature-rich
support with both Gigabit
Ethernet LAN connectivity and
WAN port adapter connectivity.
， High-availability design: 100
percent redundancy via 2 CPEs
configured for Hot Standby
Router Protocol (HSRP) or Layer
3 load balancing.
， Cost-effective route
reflector: Ideally suited as a
low cost route reflector with
its ability to hold one million
routes with its maximum of 1 GB
memory installed.
ENTERPRISE APPLICATIONS
， Secure Internet gateway:
Support for features such as IP
Security (IPSec) Protocol and
stateful firewall at very high
speeds make it an ideal Internet
gateway (security) appliance.
， Large-branch-office router:
High-performance branch-office
router with support for up to
OC-3/STM-1 or Gigabit Ethernet
connectivity.
， Network-appliance router:
Support for CiscoWorks QoS
Policy Manager and other
management tools make it an
ideal QoS appliance at the edge
of enterprise networks.
By enabling the multifunction
capabilities of the Cisco 7301,
customers can simplify their
network architectures,
significantly reduce initial
equipment costs, and increase
revenue opportunities through
value-added services.

CISCO 7301 SERIES PRODUCT SPECIFICATIONS: HARDWARE COMPONENTS
Chassis
The Cisco 7301 router is
designed with a view to enhance
operational efficiency. The 7301
incorporates a 700-MHz
integrated processor and
includes three 10/100/1000-Mbps
interfaces with both RJ-45,
three SFP optical interfaces, a
single Cisco 7000 Series router
port adapter slot, a 64-MB
compact Flash card, and
auxiliary and console ports in a
compact (1 RU) chassis.
The Cisco 7301 processor
integrates functions such as the
memory controller, system
controller, NVRAM,
console/auxiliary ports, and
Flash storage device controller,
all on the same chip as the
system CPU. That means that
these devices that were once
spread across multiple chips are
now integrated into a single
network processor, enabling the
system to run at much faster
speeds.
Table 2 provides a quick
overview of the available
options.

The Cisco 7301 chassis retains
all the important features of
the Cisco 7401, which enables it
to deliver an exceptional
price/performance ratio for
enterprises and service
providers alike.
Like the Cisco 7401, in order to
ensure high system availability
required for mission-critical
applications, the Cisco 7301
also supports:
， Physical alarm relay in case
of device failure
， Dual AC and dual DC power
supplies
， Online insertion and removal
(OIR) of port adapters
， Environmental monitors with
levels of escalation to ensure
corrective action prior to
system shutdown
Built-In LAN Ports
The Cisco 7301 processor
includes three fixed
10/100/1000-Mbps LAN interfaces
as part of the system CPU. These
interfaces run at any speed from
10 Mbps Ethernet to 1000 Mbps
Gigabit Ethernet. There is one
RJ-45 connection and one SFP
Gigabit Ethernet connection for
each interface, for a total of
three Ethernet RJ-45 and three
Small Form-Factor Pluggable
Gigabit Ethernet connections on
the Cisco 7301 faceplate, any of
which may be active at any time.
The RJ-45 interfaces have the
option of running at 10-Mb
Ethernet, 100-Mb Fast Ethernet,
or 1000-Mb Gigabit Ethernet over
copper. Industry-standard SX,
LX/LH, or ZX SFP Gigabit
Ethernet transceivers provide
Gigabit Ethernet connectivity
over fiber.
Figure 1 illustrates these
ports.
Figure 1
Cisco 7301 Series Router LAN
Ports
Connectivity
The Cisco 7301 includes a single
Cisco 7000 Series port adapter
slot, which protects existing
customer investment in
interfaces and simplifies
sparing.
The Cisco 7301 offers scalable
density with a wide range of
interfaces including:
， Ethernet, Fast Ethernet, and
Gigabit Ethernet
， Serial and multichannel
T1/E1and T3/E3 interfaces and
packet-over-SONET (POS) OC-3
， OC-3/STM-1 POS, T3/E3 and
OC-3/STM-1 ATM, and T1/E1
Inverse Multiplexing over ATM (IMA)
， ISDN Primary Rate Interface
(PRI), Basic Rate Interface (BRI), and High-Speed Serial
Interface (HSSI)
， Support for hardware
encryption and Layer 3
compression (VPN accelerator
modules)
For a detailed listing of all
port adapters supported on the
Cisco 7301 Series Router, please
contact your Cisco Sales
Representative.
The Cisco 7301 architecture is
based on a new memory
architecture type called the
double data rate (DDR) memory.
This new form of memory roughly
doubles the speed of access to
system memory. In a
store-and-forward router such as
the Cisco 7301, this provides a
clear advantage because each
packet must be individually
stored in memory, rewritten by
the system CPU, and then
transmitted out of memory to the
outbound interface.
The Cisco 7301 supports 256 MB
(default), upgradable to 512 MB,
or 1 GB of DRAM memory. There
are two DRAM memory slots, so
256 MB of memory consists of two
128-MB memory SoDIMMs, 512 MB
consists of two 256-MB memory
SoDIMMs, and 1 GB consists of
two 512-MB memory SoDIMMs.
NVRAM and Boot Flash
The NVRAM in the Cisco 7301 is
512 KB.
Boot Flash on the Cisco 7301 has
been doubled over previous Cisco
7000 Series routers to 32 MB.
This increase in size allows the
end user to keep a full boot
image in boot Flash or have
plenty of room for multiple log
file locations or backup
configuration files.
Compact Flash Memory
The Cisco 7301 also includes a
single 64-MB default compact
Flash for removable Flash
storage, upgradable to 256 MB.
The chassis are also formatted
using the ATA standard file
system format so they can be
read in other ATA routers and PC
systems with a simple compact
Flash to PCMCIA adapter module
or compact Flash reader. It is
large enough to hold at least
two Cisco IOS Software images.
Console and Auxiliary Ports
The Cisco 7301 has built-in
console and auxiliary ports on
the front end of the chassis.
Software
The Cisco 7301 supports the
following Cisco IOS releases:
， 12.2(11)YZ. This is a special
release of 12.2(11)S. Its
migration path is the third
release of 12.2S.
， 12.2(13)B required to support
16,000 subscribers.
， 12.3(2)T when the release is
available.
