ACLs. The SFP-based Gigabit Ethernet ports accommodate a range of
SFP transceivers, including the Cisco 1000BASE-SX, 1000BASE-LX,
1000BASE-BX, 1000BASE-ZX, 100BASE-FX, 100BASE-LX, 100BASE-BX, and
coarse wavelength-division multiplexing (CWDM) SFP transceivers.

GIGABIT ETHERNET
At speeds of 1000 Mbps, Gigabit Ethernet provides the bandwidth to meet
new and evolving network demands, alleviate bottlenecks, and boost
performance while increasing the return on existing infrastructure
investments. Todays workers are placing higher demands on networks,
running multiple concurrent applications. For example, a worker joins a
team conference call through an IP videoconference, sends a 10-MB
spreadsheet to meeting participants, broadcasts the latest marketing
video for the team to evaluate, and queries the customer relationship
management (CRM) database for the latest real-time feedback. Meanwhile,
a multigigabyte system backup starts in the background and the latest
virus updates are delivered to the client.

INTELLIGENCE IN THE NETWORK
Networks of today are evolving to address four new developments at the
network edge:
- Increase in desktop computing power
- Introduction of bandwidth-intensive applications
- Expansion of highly sensitive data on the network
- Presence of multiple device types, such as IP phones, WLAN access
points, and IP video cameras.
These new demands contend for resources with existing mission-critical
applications. As a result, IT professionals must view the edge of the
network as critical to effectively manage the delivery of information
and applications.
As companies increasingly rely on networks as their strategic business
infrastructure, it is more important than ever to ensure their high
availability, security, scalability, and control. By adding Cisco
intelligent functions for LAN access, you can now deploy networkwide
intelligent services that consistently address these requirements from
the desktop to the core and through the WAN.
With Cisco Catalyst Intelligent Ethernet switches, Cisco Systems helps
companies realize the full benefits of adding intelligent services into
their networks. Deploying capabilities that make the network
infrastructure highly available to accommodate time-critical needs,
scalable to accommodate growth, secure enough to protect confidential
information, and capable of differentiating and controlling traffic
flows is critical to further optimizing network operations.

ENHANCED SECURITY
The wide range of security features that the Cisco Catalyst 2960 Series
offers helps businesses protect important information, keep unauthorized
people off the network, guard privacy, and maintain uninterrupted
operation.
The Cisco Identity Based Networking Services (IBNS) solution provides
authentication, access control, and security policy administration to
secure network connectivity and resources. Cisco IBNS in the Cisco
Catalyst 2960 Series prevents unauthorized access and helps ensure that
users get only their designated privileges. It provides the ability to
dynamically administer granular levels of network access. Using the
802.1x standard and the Cisco Secure Access Control Server (ACS), users
can be assigned a VLAN upon authentication, regardless of where they
connect to the network. This setup allows IT departments to enable
strong security policies without compromising user mobility, and with
minimal administrative overhead.
To guard against denial-of-service and other attacks, ACLs can be used
to restrict access to sensitive portions of the network by denying
packets based on source and destination MAC addresses, IP addresses, or
TCP/User Datagram Protocol (UDP) ports. ACL lookups are done in
hardware, so forwarding performance is not compromised when implementing
ACL-based security.
Port security can be used to limit access on an Ethernet port based on
the MAC address of the device to which it is connected. It also can be
used to limit the total number of devices plugged into a switch port,
thereby protecting the switch from a MAC flooding attack as well as
reducing the risks of rogue wireless access points or hubs.
With Dynamic Host Configuration Protocol (DHCP) snooping, DHCP spoofing
can be thwarted by allowing only DHCP requests (but not responses) from
untrusted user-facing ports. Additionally, the DHCP Interface Tracker
(Option 82) feature helps enable granular control over IP address
assignment by augmenting a host IP address request with the switch port
ID.
The MAC Address Notification feature can be used to monitor the network
and track users by sending an alert to a management station so that
network administrators know when and where users entered the network.
Secure Shell Protocol Version 2 (SSHv2) and Simple Network Management
Protocol Version 3 (SNMPv3) encrypt administrative and network-
management information, protecting the network from tampering or
eavesdropping. TACACS+ or RADIUS authentication enables centralized
access control of switches and restricts unauthorized users from
altering the configurations. Alternatively, a local username and
password database can be configured on the switch itself. Fifteen levels
of authorization on the switch console and two levels on the Web-based
management interface provide the ability to give different levels of
configuration capabilities to different administrators.

AVAILABILITY AND SCALABILITY
The Cisco Catalyst 2960 Series is equipped with a large set of features
that allow for network scalability and higher availability through
multicast filtering as well as a complete suite of Spanning Tree
Protocol enhancements aimed to maximize availability in a Layer 2
network.
Enhancements to the standard Spanning Tree Protocol, such as Per-VLAN
Spanning Tree Plus (PVST+), UplinkFast, and PortFast, help to maximize
network uptime. PVST+ allows for Layer 2 load sharing on redundant links
to efficiently use the extra capacity inherent in a redundant design.
UplinkFast, PortFast, and BackboneFast all greatly reduce the standard
30- to 60-second Spanning Tree Protocol convergence time. Flexlink
provides bidirectional, fast convergence in less than 100 milliseconds.
The Loopguard and bridge protocol data unit (BPDU) guard enhancements
provide Spanning Tree Protocol loop avoidance.

ADVANCED QOS
The Cisco Catalyst 2960 Series offers superior multilayer QoS features
to help ensure that network traffic is classified and prioritized, and
that congestion is avoided in the best possible manner. Configuration of
QoS is greatly simplified through automatic QoS (Auto QoS), a feature
that detects Cisco IP phones and automatically configures the switch for
the appropriate classification and egress queuing. This optimizes
traffic prioritization and network availability without the challenge of
a complex configuration.
The Cisco Catalyst 2960 Series can classify, reclassify, police, mark,
queue, and schedule incoming packets and can queue and schedule packets
at egress. Packet classification allows the network elements to
discriminate between various traffic flows and enforce policies based on
Layer 2 and Layer 3 QoS fields.
To implement QoS, the Cisco Catalyst 2960 Series Switch first identifies
traffic flows or packet groups, then classifies or reclassifies these
groups using the differentiated services code point (DSCP) field or the
802.1p class of service (CoS) field. Classification and reclassification
can be based on criteria as specific as the source or destination IP
address, source or destination MAC address, or the Layer 4 TCP or UDP
port. At the ingress, the Catalyst 2960 Series also polices to determine
whether a packet is in or out of profile, marks to change the
classification label, passes through or drops out of profile packets,
and queues packets based on classification. Control-plane and data-plane
ACLs are supported on all ports to help ensure proper treatment on a
per-packet basis.
The Cisco Catalyst 2960 Series supports four egress queues per port,
giving network administrators more control in assigning priorities for
the various applications on the LAN. At egress, the switch performs
congestion control and scheduling, the algorithm or process that
determines the order in which queues are processed. The Catalyst 2960
Series Switch supports Shaped Round Robin (SRR) and strict priority
queuing. The SRR algorithm helps ensure differential prioritization.
These QoS features allow network administrators to prioritize mission-
critical and bandwidth-intensive traffic, such as enterprise resource
planning (ERP), voice (IP telephony traffic), and computer-aided design
and manufacturing (CAD/CAM), over applications such as FTP or e-mail.
For example, it would be undesirable to have a large file download
destined to one port on a switch increase latency in voice traffic
destined to another port on this switch. This condition is avoided by
ensuring that voice traffic is properly classified and prioritized
throughout the network. Other applications, such as Web browsing, can be
handled on a lower-priority basis.
The Cisco Catalyst 2960 Series can perform rate limiting through its
support of the Cisco committed information rate (CIR) function. Through
CIR, bandwidth can be guaranteed in increments as small as 1 Mbps.
Bandwidth can be allocated based on several criteria, including MAC
source address, MAC destination address, IP source address, IP
destination address, and TCP or UDP port number. Bandwidth allocation is
essential when network environments require service-level agreements or
when it is necessary to control the bandwidth given to certain users.

MANAGEMENT
The new Express Setup feature simplifies the initial configuration of a
switch. Now you can set up the switch through a Web browser, eliminating
the need for terminal-emulation programs and the command-line interface
(CLI). Express Setup reduces the cost of deployment by helping less-
skilled personnel quickly and easily set up switches.
Cisco Network Assistant is a PC-based network-management application
optimized for LANs with up to 250 users. Cisco Network Assistant offers
centralized management of Cisco switches, routers, and WLAN access
points. It supports a wide range of Cisco Catalyst intelligent switches
from Cisco Catalyst 2960 through Cisco Catalyst 4506. Through a user-
friendly GUI, users can configure and manage a wide array of switch
functions and start the device manager of Cisco routers and Cisco
wireless access points. A few mouse clicks enable the Cisco recommended
security, availability, and QoS features without the need to consult a
detailed design guide. The Security wizard automatically restricts
unauthorized access to servers with sensitive data. Smartports and
wizards save time for network administrators, reduce human errors, and
help ensure that the configuration of the switch is optimized for these
applications. Available at no cost, Cisco Network Assistant can be
downloaded from the Cisco Website.
In addition to Cisco Network Assistant, Cisco Catalyst 2960 Series
switches provide for extensive management using SNMP network-management
platforms such as CiscoWorks for Switched Internetworks. Managed with
CiscoWorks, Cisco Catalyst switches can be configured and managed to
deliver end-to-end device, VLAN, traffic, and policy management.
Additionally, the CiscoWorks Resource Manager Essentials, a Web-based
management tool, helps enable automated inventory collection, software
deployment, easy tracking of network changes, views into device
availability, and quick isolation of error conditions.

The internal power supply supports input voltages between
100 and 240 VAC.
Use the supplied AC power cord to connect the AC power
connector to an AC power outlet.
The connector offers connection for an optional Cisco RPS
675 that uses AC input and supplies DC output to the
switch.
The connector offers a 675W redundant power system that
supports up to six external network devices and
provides power to one failed device at a time.
The connector automatically senses when the internal
power supply of a connected device fails and provides
power to the failed device, preventing loss of network
traffic.
