The Cisco Catalyst 2970 Series switches are affordable Gigabit-to-the-desktop
Ethernet switches that deliver wire-speed intelligent services for small and
medium-sized businesses and enterprise branch offices. Featuring a complete set
of intelligent services, the Cisco Catalyst 2970 Series switches can enhance
network performance and increase productivity for today`s knowledge workers by
intelligently scaling beyond 100 Mbps.
The following two configurations make up the Cisco Catalyst 2970 Series:
Cisco Catalyst 2970G-24TS㬔 Ethernet 10/100/1000 ports and 4 small
form-factor pluggable (SFP) ports
Cisco Catalyst 2970G-24T㬔 Ethernet 10/100/1000 ports
Available with Cisco Enhanced Image (EI) IOS software, the Cisco Catalyst
2970 Series offers a complete set of intelligent multilayer services that
deliver security, quality of service (QoS), and availability with the simplicity
of traditional LAN switching. Features such as access control list (ACL)
filtering and QoS classification bring security to the edge of the network and
enable applications such as IP telephony and real-time streaming multimedia.
Cisco Catalyst 2950 Series switches include Cisco Cluster Management Suite
(CMS) software, which allows users to simultaneously configure and troubleshoot
multiple Cisco Catalyst desktop switches using a standard Web browser. In
addition to Cisco CMS software, Cisco Catalyst 2950 Series switches provide
extensive management tools that are used with Simple Network Management Protocol
(SNMP) network management platforms such as CiscoWorks. To further enhance the
out-of-the-box manageability of the Catalyst 2970 Series switches, the newly
launched Express Setup simplifies initial configuration with a Web browser. The
Web interface enables less-skilled personnel to quickly and simply set up
switches, thereby reducing the cost of deployment.
Today`s knowledge workers increasingly need more bandwidth to run multiple,
concurrent applications and maintain full productivity. 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 database
for the latest real-time feedback. Meanwhile, the multigigabyte system backup
starts in the background and the latest virus updates are pushed to the client.
Bandwidth enhancement beyond 100 Mbps—enabled by Gigabit Ethernet—provides for a
smoothly operating network and offers the possibility of even higher rates of
productivity in the future.
Cisco makes the transition to Gigabit Ethernet faster and easier with
standards-based solutions for both fiber and copper cabling. At speeds of 1000
Mbps, Gigabit Ethernet provides the bandwidth that networks need to meet new and
evolving network demands, alleviate bottlenecks, and boost performance while
increasing the return on existing infrastructure investments. Customers having
small and medium-sized networks with Cisco Catalyst 2950 Series switches
deployed in the access layer will find the Cisco Catalyst 2970 Series a
cost-effective switch platform with which to begin the migration to Gigabit
Ethernet.
As companies increasingly rely on the network as the strategic business
infrastructure, and with end users having 1000 Mbps at their disposal, it is
important to consistently ensure network security, high availability, and QoS
from the desktop through the network core and out to the WAN. Cisco Catalyst
switches enable companies to realize the full benefits of adding intelligent
services to their networks. These capabilities make the network infrastructure
secure and protect confidential information. They also enable the network to
meet users` time-critical needs while remaining capable of accommodating future
growth. Finally the capabilities make it possible to differentiate and control
traffic flows, so that a greater number of critical business applications can be
handled.
With the wide range of security features that the Cisco Catalyst 2970
Series offers, businesses can protect important information, keep unauthorized
people off of the network, guard privacy, and maintain uninterrupted
operation.
The Cisco Catalyst 2970 Series offers several high-availability features
that reduce network downtime, maintain mission-critical applications, and
reduce total cost of ownership.
Customers can achieve maximum power availability for a converged voice and
data network when a Cisco Catalyst 2970 Series switch is combined with the
Cisco Redundant Power System (RPS) 675 for seamless protection against
internal power supply failures.
The Cisco Catalyst 2970 Series offers superior multilayer, granular QoS
features that prevent congestion and help ensure that network traffic is
properly classified and prioritized. Configuration of QoS is greatly
simplified through Automatic QoS (AutoQoS), a feature that detects Cisco IP
phones and automatically configures switches for the appropriate
classification and egress queuing. This optimizes traffic prioritization and
network availability without requiring complex configuration.
Cisco is committed to minimizing total cost of ownership and offers a
portfolio of technical support services to help ensure that Cisco products
operate efficiently, remain highly available, and benefit from the most
up-to-date system software. The services and support programs described in the
table below are available as part of the Cisco Desktop Switching Service and
