Cisco EnergyWise Technology: Good for
Business, Better for Environment
Cisco EnergyWise is an innovative architecture, added to the
Cisco Catalyst 2960 switches, that enable the measurement of
power consumption in the network infrastructure and network
attached devices. EnergyWise encompasses a highly
intelligent network based approach to communicate messages
that measure and control energy between network devices and
end points. The network discovers Cisco EnergyWise
manageable devices, monitors their power consumption, and
takes action based on business rules to reduce power
consumption. EnergyWise uses a unique domain naming system
to query and summarize information from large sets of
devices making it simpler than traditional network
management capabilities. Cisco EnergyWise's management
interfaces allow facilities and network management
applications to communicate with end points and each other
using the network as a unifying fabric. The management
interface uses standard SNMP or SSL to integrate Cisco and
third party management systems.
Cisco EnergyWise extends the network as a platform for power
control plane for gathering, managing and reducing power
consumption of all devices, resulting in company-wide
optimized power delivery and reduced energy costs. Together,
Cisco EnergyWise technology and Catalyst switches enable
Greenhouse Gas (GhG) emissions reduction, increased energy
cost savings and sustainable business behavior.
Power over Ethernet
The Cisco Catalyst 2960 Series provide PoE to allow easy
connectivity to Ethernet-powered devices including Cisco IP
phones and wireless access points. Cisco Catalyst 2960 PoE
models comply with Cisco pre-standard PoE and IEEE 802.3af.
PoE removes the need for wall power to each PoE-enabled
device and eliminates the cost for additional electrical
cable and circuits that would otherwise be necessary in IP
phone and WLAN deployments. PoE switches also eliminate the
need for power injectors and PoE mid-spans for powering IP
devices. The Cisco Catalyst 2960-48PST-L can support 48 PoE
ports with total PoE power output capacity at 370W. Taking
advantage of Cisco Catalyst Intelligent Power Management,
the Cisco Catalyst 2960-48PST-L configuration can deliver
the necessary power to support 24 ports at 15.4W, 48 ports
at 7.7W, or any combination in between. Cisco Catalyst
2960-24PC-L can support 24 simultaneous full-powered PoE
port at 15.4W. The Cisco Catalyst 2960-24LT-L has 24 10/100
ports with 8 simultaneous full-powered PoE ports at 15.4W.
The Cisco Catalyst 2960-8TT-L has eight 10/100 ports with
one 10/100/1000 PoE input port. This switch does not need a
power supply and receives power over the uplink from an
upstream PoE device, providing deployment flexibility and
availability. It is ideal for wiring and space-constraint
applications. The power adaptor (PWR-A=) and power cord are
optional and may be ordered separately.
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. Today's 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.
Redundant Power System
The Cisco Catalyst 2960 Series Switches support the new
generation of the Cisco Redundant Power System (RPS) 2300,
which increases availability in a converged data, voice, and
video network by providing transparent power backup to two
of six attached switches at the same time.
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 help 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.
Cisco Catalyst Intelligent Ethernet switches help you
realize the full benefits of adding intelligent services
into your 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 LAN Base Series offers helps you 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 LAN Base 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 (DoS) 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
ACL-based security is implemented.
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.
Intelligent PoE Management
The Cisco Catalyst 2960 PoE models support Cisco IP phones
and Cisco Aironet®
wireless LAN access points, as well as any IEEE
802.3af-compliant end device.
- Cisco Discovery Protocol version 2
allows the Cisco Catalyst 2960 Series Switch to negotiate a more
granular power setting when connecting to a Cisco powered
device, such as IP phones or access points, than what is
provided by IEEE classification.
- The PoE MIB provides proactive
visibility into power usage and allows you to set different
power level thresholds.
- Link Layer Discovery Protocol (LLDP and
LLDP-MED) adds support for IEEE 802.1AB link layer discovery
protocol for interoperability in multivendor networks. Switches
exchange speed, duplex, and power settings with end devices such
as IP phones.
Availability and Scalability
The Cisco Catalyst 2960 LAN Base 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.
Voice-aware 802.1x port security disables the offending data
VLAN when a violation is detected without affecting Voice
VLAN on the same switch port. Enhancements to the standard
Spanning Tree Protocol, such as Per-VLAN Spanning Tree Plus
(PVST+), UplinkFast, and PortFast help 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 LAN Base 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 LAN Base 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 LAN Base 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
Cisco Catalyst 2960 LAN Base 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 LAN Base 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 Cisco Catalyst 2960
LAN Base 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 making sure 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 LAN Base 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

all ports help ensure proper marking on a
per-packet basis.
- Four egress queues per port enable
differentiated management of up to four traffic
types.
- SRR scheduling ensures differential
prioritization of packet flows by intelligently
servicing the ingress and egress queues.
- Weighted tail drop (WTD) provides congestion
avoidance at the ingress and egress queues
before a disruption occurs.
- Strict priority queuing guarantees that the
highest-priority packets are serviced ahead of
all other traffic.
- There is no performance penalty for highly
granular QoS functions.
|
| Granular Rate Limiting |
- The Cisco CIR function guarantees bandwidth in
increments as small as 1 Mbps.
- Rate limiting is provided based on source and
destination IP address, source and destination
MAC address, Layer 4 TCP and UDP information, or
any combination of these fields, using QoS ACLs
(IP ACLs or MAC ACLs), class maps, and policy
maps.
- Asynchronous data flows upstream and
downstream from the end station or on the uplink
are easily managed using ingress policing and
egress shaping.
- Up to 64 aggregate or individual polices are
available per Fast Ethernet or Gigabit Ethernet
port.

Security |
| Networkwide Security
Features |
- IEEE 802.1x allows dynamic, port-based
security, providing user authentication.
- IEEE 802.1x with VLAN assignment allows a
dynamic VLAN assignment for a specific user
regardless of where the user is connected.
- IEEE 802.1x with voice VLAN permits an IP
phone to access the voice VLAN irrespective of
the authorized or unauthorized state of the
port.
- IEEE 802.1x and port security are provided to
authenticate the port and manage network access
for all MAC addresses, including those of the
client.
- IEEE 802.1x with Guest VLAN allows guests
without 802.1x clients to have limited network
access on the guest VLAN.
- Web authentication for non-802.1x clients
allows non-802.1x clients to use an SSL-based
browser for authentication.
- MAC Auth Bypass (MAB) for voice allows
third-party IP phones without an 802.1x
supplicant to get authenticated using their MAC
address.
- Port-based ACLs for Layer 2 interfaces allow
application of security policies on individual
switch ports.
- Unicast MAC filtering prevents the forwarding
of any type of packet with a matching MAC
address.
- Unknown unicast and multicast port blocking
allows tight control by filtering packets that
the switch has not already learned how to
forward.
- SSHv2 and SNMPv3 provide network security by
encrypting administrator traffic during Telnet
and SNMP sessions. SSHv2 and the cryptographic
version of SNMPv3 require a special
cryptographic software image because of U.S.
export restrictions.
- Bidirectional data support on the Switched
Port Analyzer (SPAN) port allows the Cisco
Secure intrusion detection system (IDS) to take
action when an intruder is detected.
- TACACS+ and RADIUS authentication enable
centralized control of the switch and restrict
unauthorized users from altering the
configuration.
- MAC address notification allows administrators
to be notified of users added to or removed from
the network.
- DHCP snooping allows administrators to ensure
consistent mapping of IP to MAC addresses. This
can be used to prevent attacks that attempt to
poison the DHCP binding database, and to
rate-limit the amount of DHCP traffic that
enters a switch port.
- DHCP Interface Tracker (Option 82) feature
augments a host IP address request with the
switch port ID.
- Port security secures the access to an access
or trunk port based on MAC address.
- After a specific timeframe, the aging feature
removes the MAC address from the switch to allow
another device to connect to the same port.
- Trusted Boundary provides the ability to trust
the QoS priority settings if an IP phone is
present and to disable the trust setting if the
IP phone is removed, thereby preventing a
malicious user from overriding prioritization
policies in the network.
- Multilevel security on console access prevents
unauthorized users from altering the switch
configuration.
- The user-selectable address-learning mode
simplifies configuration and enhances security.
- BPDU Guard shuts down Spanning Tree Protocol
PortFast-enabled interfaces when BPDUs are
received to avoid accidental topology loops.
- Spanning-Tree Root Guard (STRG) prevents edge
devices not in the network administrator's
control from becoming Spanning Tree Protocol
root nodes.
- Voice VLAN aware port security and BPDU Guard
allow Voice VLAN traffic to not be disrupted
when security violations occur.
- IGMP filtering provides multicast
authentication by filtering out no subscribers
and limits the number of concurrent multicast
streams available per port.
- Dynamic VLAN assignment is supported through
implementation of VLAN Membership Policy Server
(VMPS) client functions to provide flexibility
in assigning ports to VLANs. Dynamic VLAN helps
enable the fast assignment of IP addresses.
- Cisco Network Assistant software security
wizards ease the deployment of security features
for restricting user access to a server as well
as to a portion of or the entire network.
- Up to 512 (Aces) are supported, with two
profiles: Security (384 Security ACL entries and
128 QoS policies), and QoS (128 Security ACL
entries and 384 QoS policies).

Power Connectors |
- Customers can provide power to a switch by
using either the internal power supply or the
Cisco RPS 675. The connectors are located at the
back of the switch.
Note: The Catalyst
2960-8TC-L and Catalyst 2960G-8TC-L do not have RPS
ports.
- Internal-Power-Supply Connector
- The internal power supply is an autoranging
unit.
- The internal power supply supports input
voltages between 100 and 240VAC.
- Use the supplied AC power cord to connect the
AC power connector to an AC power outlet.
- Cisco RPS Connector
- The connector offers connection for an
optional Cisco RPS 2300 that uses AC input and
supplies DC output to the switch.
- The connector offers a 2300W redundant power
system that supports up to six external network
devices and provides power to two failed devices
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.
- Only the Cisco RPS 2300 (model PWR-RPS2300)
should be attached to the redundant-power-system
receptacle.

Note: All power consumption numbers
were measured under controlled laboratory conditions and are
provided as an estimate.
The wattage rating on the power supply does not represent
actual power draw. It indicates the maximum power draw
possible by the power supply. This rating can be used for
facility capacity planning. For PoE switches, cooling
requirements are smaller than the actual power consumption
as a significant portion of PoE loads are dissipated in the
end points
Non PoE Power Consumption

The numbers indicate the power consumed by a typical switch
under normal conditions. Normal conditions signify a
temperature of 25 Degrees Celsius, atmospheric pressure in
the range of 860 to 1060 mbar and relative Humidity between
30 to 75%. Typically such power draws are only seen when
encountering a 100% traffic load made up entirely of 64 byte
packets on the switch and the uplinks.
5% Throughput Switch Power consumption
The numbers indicate the power consumed by a typical switch
