Stan: Używany

Do sprzedania router Cisco 1720. Stan idealny. Od zakupu parę razy używany po czym ok rok przeleżał w pudełku. Stan idealny + komplet kabli i zasilacz. Router świetny, bawiliśmy się podobnym modelem na studiach, wszystko się da skonfigurować do potrzeb małej firmy (mówię o VLAnach i polityce bezpieczeństwa między nimi), ale częściej pracowaliśmy na Omniswitchach i Lucentach więc wszystkiego o tym routerze się nie dowiedziałem :). Jednym słowem polecam. Mi on już nie jest potrzebny bo nie mam żadnej firmy, a testów już nie potrzebuje robić :)

Na ostatnim zdjęciu pokazałem ile jest zainstalowanej pamięci RAM - 16MB (100MHz).

Zapraszam do licytacji.

Opis ze strony producenta:

The Cisco 1721 Modular Access Router is designed to help organizations embrace the productivity benefits of e-business applications. The Cisco 1721 router enables e-business by delivering secure Internet, intranet, and extranet access with virtual private networks (VPNs) and firewall technology. The Cisco 1721 router offers:

Wide array of WAN access options, including high-speed business-class digital subscriber line (DSL)
High-performance routing with bandwidth management
Inter-virtual LAN (VLAN) routing
VPN access with firewall option

The Cisco 1721 router offers the following key features:

A RISC processor to support high-performance routing, encryption, and broadband services
One autosensing 10/100 Fast Ethernet port
Two WAN interface card (WIC) slots that support the same data WAN interface cards as the Cisco 1600, 2600, and 3700 routers
One auxiliary (AUX) port (up to 115.2-kbps asynchronous serial)
One console port
One internal expansion slot for the hardware-assisted VPN encryption card (MOD1700-VPN)

The Cisco 1700 Series supports the value of end-to-end Cisco network solutions with the following benefits:

Flexibility—The modular Cisco 1721 adapts easily to fit the needs of growing businesses. Interchangeable WAN interface cards enable easy additions or changes in WAN technologies without requiring a forklift upgrade of the entire platform. Modular data slots enable users to tailor data services as needed.
Security—The Cisco 1721 supports hardware-assisted wire-speed Triple Digital Encryption Standard IP Security (3DES IPSec) VPN encryption (using optional VPN module), a Cisco IOS Software-based stateful inspection firewall, and an intrusion detection system (IDS) that allows customers to keep their data safe.
Business-class DSL—Business-class DSL is delivered through the optional asymmetric DSL (ADSL) or symmetrical high-bit rate DSL (G.shdsl) WICs. The Cisco 1700 Series business-class DSL solution combines the cost benefits of DSL service with the advanced routing capability required for business use of the Internet. Through enhanced DSL quality-of-service (QoS) features, performance levels for mission-critical applications and toll-quality voice/data integration are guaranteed.
Traffic management—The Cisco 1721 is based on Cisco IOS Software, the accepted standard for Internet operations. Cisco IOS Software allows traffic prioritization by user or application, ensuring that the most strategic e-business applications and time-sensitive applications perform as expected.
