Buy used Cisco WS-C2948G-L3, Cisco 2948G switch

The Catalyst WS-C2948G-L3switch provides non-blocking routing and switching for IP, IPX, and IP multicast while also offering wire-speed Layer 2 switching for non-routable protocols such as NetBIOS and DECnet local-area transport (LAT). This capability allows network managers to augment their multi- protocol backbones with the Catalyst WS-C2948G-L3without having to build parallel networks, as is often required with IP-only switches.

Catalyst WS-C2948G-L3Features

Dedicated 48 ports of 10/100-Mbps Ethernet and two ports of 1000BaseX Gigabit Ethernet with gigabit interface converter (GBIC) support; all ports with Layer 3 switching capability
10 Mpps Layer 3 switching and routing of IP, IPX switches, and IP multicast
22 Gbps non-blocking switch fabric
High-performance CPU with Cisco IOS system software
Quality of service (QoS)?multiple queues with weighted round robin (WRR) scheduling
Comprehensive management tools based on standard CiscoWorks2000 applications
Optional redundant external power supply

Catalyst WS-C2948G-L3Product overview

The Catalyst WS-C2948G-L3is a fixed-configuration Layer 3 Ethernet switch with 48 RJ-45 10/100 ports and two Gigabit Ethernet uplink ports with modular GBIC interfaces. The switch is ideal for backbone deployment in small to mid-sized networks that require wire-speed Layer 3 performance but do not require the high 10/100 Mbps Ethernet port counts or Gigabit Ethernet density offered in the Catalyst 6000 and Catalyst 8500 series of switches.
Catalyst WS-C2948G-L3Overview

The Catalyst WS-C2948G-L3provides an aggregate throughput of more than 10 Mpps for Layer 3 switching. These data rates apply not only to IP and IPX traffic but also to IP multicast and bridged traffic and are a result of using high-speed application-specific integrated circuit (ASIC) technology on each port to perform true Layer 3 switching. The Catalyst WS-C2948G-L3supports a high-performance architecture with 22 Gbps bandwidth. The switch fabric is capable of supporting all 48 10/100 ports and two Gigabit uplinks simultaneously at wire speed.

The Catalyst WS-C2948G-L3is housed in a 1.5 rack unit (RU) chassis and can be provisioned with an optional external redundant power supply. It supports a 22 Gbps shared-memory, fully non-blocking switch fabric, high- performance RISC processor that provides the routing intelligence and individual port-based ASICs for the Layer 3 switching. The Catalyst WS-C2948G-L3uses Cisco Express Forwarding (CEF), which has been developed for the Cisco 12000 series gigabit switch router (GSR), the Catalyst 8500, and the Cisco 7500. This technology provides Layer 3 switching based on a topology map of the entire network that is distributed to each port-based ASIC, allowing it to make autonomous switching decisions without the involvement of a centralized CPU.
