Pre-owned, used and refurbished Cisco WS-C2948G-L3

The Cisco WS-C2948G-L3 is the Cisco 2948 L3 Layer 3 Switch with 48 10/100 ports and 2 GBIC Slots. As a fixed-configuration switch, a new or used WS-C2948G-L3 provides non-blocking routing and switching for IP, IPX, and IP multicast. Compact, a new surplus or refurbished WS-C2948G-L3 is perfect for midsize campus backbones looking to aggregate multiprotocol traffic from multiple workgroup switches or wiring closets.

The WS-C2948G-L3 available is just one of the many options available in the extensive MULTI-LINK (MLCP) switch equipment inventory. Because we maintain a large WS-C2948G-L3 inventory, MULTI-LINK can often ship within 1-2 days or even on the same day you order!

We provide an extensive selection of current and previous generation equipment, ranging from interface cards to fixed-configuration and modular switches, to other insert components. Whatever your Cisco switch requirement, MULTI-LINK strives to build a relationship with you that will last for years to come.

At MULTI-LINK, we guarantee all used and refurbished WS-C2948G-L3 will be tested to factory specifications by our onsite technicians, and we'll back it with our standard lifetime warranty.

General Information

Product Type: Ethernet Switch
Marketing Information
The Catalyst 2948G-L3 provides 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 2948G-L3 supports 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 2948G-L3 is 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 2948G-L3 uses 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.
