Cisco Catalyst 2970 Series Switches

The Cisco

Catalyst

2970 Series Switches are affordable Gigabit Ethernet switches

that deliver wire-speed intelligent services for small and medium businesses and

enterprise branch ofﬁces. Featuring a complete set of intelligent services, the

Catalyst 2970 Series Switches can enhance network performance and increase

productivity for today’s knowledge workers by intelligently scaling beyond

100 Mbps over existing Category 5 copper cabling.

TheCiscoCatalyst2970 Seriesis partof the

industry’smostcompleterange of stackable

and standalone switches, including the

CiscoCatalyst2940,2950,3550, and3750

Series Switches. Cisco’s suite of ﬁxed

conﬁguration switches provides Fast

Ethernet and Gigabit Ethernet

conﬁgurations with intelligent services to

small and medium-sized businesses and

enterprise branch ofﬁces.

Cisco ﬁxed conﬁguration switches are part

ofalarger familyofCiscoCatalyst switches

that include the Cisco Catalyst 6500 and

4500 Series modular switches. The entire

familyoffers industry-leadingperformance,

functionality, scalability, and ﬂexibility.

Configuration

The following twoconﬁgurations comprise

the Cisco Catalyst 2970 Series:

• Cisco Catalyst 2970G-24TS—24

Ethernet10/100/1000ports and 4small

form-factor pluggable (SFP) ports

• Cisco Catalyst 2970G-24T—24

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 to deliver security,

quality of service (QoS), and availability

with the simplicity of traditional LAN

Data Sheet Cisco Catalyst 2970 Series Switches The Cisco® Catalyst® 2970 Series Switches are affordable Gigabit Ethernet switches that deliver wire-speed intelligent services for small and medium businesses and enterprise branch offices. Featuring a complete set of intelligent services, the Catalyst 2970 Series Switches can enhance network performance and increase productivity for today’s knowledge workers by intelligently scaling beyond 100 Mbps over existing Category 5 copper cabling.

Gigabit Ethernet Today’s knowledge workers are placing higher demands on their networks. They need to run multiple, concurrent applications, and to do this productively, these users require higher bandwidth from the network. For example, a worker joins a team conference call via 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.

To guard against denial-of-service and other attacks, ACLs can be used to restrict access to sensitive portions of the network, blocking unauthorized access to servers and applications, by denying packets based on source and destination MAC addresses, IP addresses, or Transmission Control Protocol/User Datagram Protocol (TCP/UDP) ports. ACL lookups are done in hardware, so forwarding performance is not compromised when implementing ACL-based security.
PAGE 4
The Cisco Catalyst 2970 Series can classify, 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 to enforce policies based on Layer 2 and Layer 3 QoS fields.
