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.
Figure 1. Cisco Catalyst 2970 Series Switches
The Cisco Catalyst 2970 Series is part of the industry's most complete range of stackable and standalone switches, including the Cisco Catalyst 2940, 2950, 2960, 3550, 3560, and 3750 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 of a larger family of Cisco Catalyst switches that include the Cisco Catalyst 6500 and 4500 Series modular switches. The entire family offers industry-leading performance, functionality, scalability, and flexibility.
The following two configurations comprise the Cisco Catalyst 2970 Series:
• Cisco Catalyst 2970G-24TS-24 Ethernet 10/100/1000 ports and 4 small form-factor pluggable (SFP) 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 switching. Features such as Identity Based Network Services and multilayer QoS capabilities bring security to the edge of the network while enabling applications such as IP telephony and real-time streaming multimedia.
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. Meanwhile, the multi-gigabyte 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 with the ability to evolve.
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. 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.
INTELLIGENCE IN THE NETWORK
As companies increasingly rely on the network as the strategic business infrastructure, and with end users having 1000Mbps at their disposal, it is more important than ever 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 into their networks. These capabilities make the network infrastructure
• Secure to protect confidential information
• Highly available to deliver on time-critical needs
• Scalable to accommodate future growth
• Capable of differentiating and controlling traffic flows to handle the increasing number of critical business applications
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 Identity-Based Networking Services (IBNS) feature in the Cisco Catalyst 2970 Series prevents unauthorized access and helps to 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 virtual LAN (VLAN) or an ACL upon authentication, regardless of where they connect to the network. This 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, 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.
Port security can be used to limit access on an Ethernet port based on the MAC address of the device that is connected to it. It can also limit the total number of devices plugged into a switch port, reducing the risks of rogue wireless access points or hubs.
Secure Shell (SSH), Kerberos, and Simple Network Management Protocol Version 3 (SNMPv3) encrypt administrative and network management information, protecting the network from tampering or eavesdropping. Terminal Access Controller Access Control System (TACACS+) and Remote Access Dial-In User Service (RADIUS) authentication enable centralized access control of switches and restrict 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.
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. The Dynamic Host Configuration Protocol (DHCP) Interface Tracker (Option 82) feature tracks where a user is physically connected on a network by providing both the switch and the port ID to a DHCP server.
The Private VLAN Edge feature isolates ports on a switch, helping to ensure that traffic travels directly from the entry point to the aggregation device through a virtual path and cannot be directed to another port.
The Cisco Catalyst 2970 Series offers several high-availability features to reduce network downtime, maintain mission-critical applications, and reduce total cost of ownership.
Enhancements to the standard Spanning-Tree Protocol, such as Per-VLAN Spanning-Tree Plus (PVST+), UplinkFast, and PortFast 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. Loop Guard and Bridge Protocol Data Unit (BPDU) Guard provide Spanning-Tree Protocol loop avoidance.
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 to avoid 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 the challenge of complex configuration.
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.
To implement QoS, the Cisco Catalyst 2970 Series Switch first identifies traffic flows or packet groups, and classifies or reclassifies these groups using the Differentiated Services Code Point field (DSCP) or the 802.1p class-of-service (CoS) field. Classification can be based on criteria as specific as the source/destination IP address, source/destination MAC address, or the Layer 4 TCP/UDP port. At the ingress, the Cisco Catalyst 2970 will also police to determine whether a packet is in or out of profile, mark to change the classification label, pass through, or drop out of profile packets, queue packets based on classification, and service based on configured weights. Control plane and data plane ACLs are supported on all ports to ensure proper treatment on a per-packet basis. The Cisco Catalyst 2970 Series Switch supports four egress queues per port, which allows the network administrator to be discriminating and specific in assigning priorities for the various applications on the LAN. At egress, the switch performs scheduling and congestion control. Scheduling is a process that determines the order in which the queues are processed. The Cisco Catalyst 2970 Series Switch supports Shaped Round Robin (SRR) and strict priority queuing. The SRR queuing algorithm helps to ensure differential prioritization.
The Catalyst 2970 series comes with an embedded GUI device manager that simplifies initial configuration of a switch. Users now have the option to set up the switch through a Web browser, eliminating the need for more complex terminal emulation programs and knowledge of the command-line interface (CLI). Cisco Smartports have preset Cisco recommended network configurations including quality of service, security, and multicast settings to allow for transparent integration of data, video, IP communications, and wireless LAN applications.
Users can also manage the Catalyst 2970 series with Cisco Network Assistant, an advanced PC-based network management application. Cisco Network Assistant offers centralized management and configuration of Cisco switches and other Cisco devices such as routers and wireless access points. With Cisco Network Assistant, in addition to configuring multiple switches at a time, you can configure Cisco wireless access points, and invoke the device manager on Cisco routers and access points. Software upgrades on Cisco switches, routers, and wireless access points are as easy as a drag-and-drop process. You can download Cisco Network Assistant (available at no cost) from the Cisco website
In addition to Cisco Network Assistant, Cisco Catalyst 2970 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. Coupled with CiscoWorks Cisco Resource Manager Essentials, a Web-based management tool, offers automated inventory collection, software deployment, easy tracking of network changes, views into device availability, and quick isolation of error conditions.
