Desktop Connection Protection: Catalyst 2980G-A

Dedicated 80-Port 10/100 for the Wiring Closet

TheCatalyst 2980G-Ais aﬁxed-conﬁguration, Layer2 Ethernetswitch with80 RJ-4510/100 portsand two-Gigabit

Ethernet uplink ports with modular GBIC interfaces. The full functionality and connectivity in a compact package

eliminates the need for extra modules, cabling, or conﬁguration in many small- to medium-sized enterprise wiring

closets.

Industry-leading Catalyst System Software

The Catalyst 2980G-A supports the full set of features found in enterprise Catalyst system software. Not only does

this ensure interoperability with otherCatalyst switches (such as the Catalyst 4000 and 5000/5500 and 6000 series),

but it also provides the Catalyst 2980G-A with the most comprehensive set of Layer 2 features available in the

industry. Major software feature categories supported by the Catalyst 2980G-A include:

• Advanced scalability (such as Fast EtherChannel

, 802.3ad, Dynamic Virtual LANs [VLANs], and 802.1Q

Trunking)

• Bandwidth management (such as quality of service, protocol ﬁltering, and link load balancing)

• Network resiliency (UplinkFast, PortFast, and Spanning-Tree Protocol, 802.1w, 802.1s)

• Security (such as per port security, authentication, 802.1x, Private VLANs,and Internet Protocol [IP] permit lists)

• Web-based and CiscoWorks2000 management

Flexible, Full-Duplex Gigabit Uplinks

Each Catalyst 2980G-A comes standard with dual GBIC slots that can be conﬁgured with a variety of interfaces

depending upon the customer’s network requirements. Utilizing advanced GBIC technology, customers can choose

either shortwave (1000BASE-SX), long-wave (1000BASE-LX/LH), or extended-reach (1000Base-ZX) Gigabit

interfaces depending on network configuration requirements. And if in the future the customer’s Gigabit interface

requirementchanges, theGBICs caneasily (andinexpensively) be changed.(Notethat GBICs aresoldseparately fromthe

Catalyst 2980G-A.)

High–Performance, Non-Blocking Architecture

The Catalyst 2980G-A supports a high-performance architecture with 24 Gbps total capacity. The switch fabric

is capable of supporting all 80 ports simultaneously at wire speed. The high-performance fabric on the

Catalyst 2980G-A will minimize trafﬁc congestion from growth and improve the overall network response time.

Built-In Fault Tolerance

The Catalyst 2980G-A supports a variety of fault-tolerant features including support of multiple load-sharing trunks

(FastEtherChannel), multipleSpanning-Trees, andfast-convergence softwaretools suchasPortFastand UplinkFast.This

wide range of fault-tolerant tools, both hardware and software, enable the Catalyst 2980G-A to provide the platform

resiliency and fault tolerance required in today’s mission-critical networks.
