High-Performance, Reliable Switching for Small Businesses


• 48 high-speed ports optimized for performance and to support bandwidth-intensive applications

• Strong security protects network traffic to keep unauthorized users off the network

• Intelligent QoS helps ensure a consistent network experience and supports networked applications including voice, video, and data storage

• Simplified, web-based management for easy installation and configuration

Product Overview

Small businesses require cost-effective yet scalable networking solutions that can meet changing business needs. The Cisco® SRW2048 48-Port Gigabit Switch (Figure 1) brings Gigabit speeds to your users and servers, while increasing the intelligence and security of the network infrastructure. The forty-eight 10/100/1000 Mbps ports enable you to take advantage of the Gigabit Ethernet interfaces shipping in the current generation of servers, workstations, and storage devices, in addition to supporting your existing 10/100 Mbps clients. The optional Gigabit optical interfaces allow you to expand the network as your business grows.
Network security is a top priority in any size business. Most business data networks, large and small, are unsecure. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW2048 helps secure the network by using 802.1X port authentication, access control lists (ACLs), and MAC addresses port locking. The 802.1X standard requires clients to authenticate themselves before the port will pass data for them.
Businesses are recognizing the benefits of voice over IP (VoIP) and are quickly migrating their voice services to IP-based platforms, requiring their local area networks to support both voice and data applications. In unmanaged IP networks, bursty data sessions can disrupt voice packet delivery, causing poor voice quality. With the enhanced QoS and traffic management features in the Cisco SRW2048, voice data can be prioritized, helping ensure clear and reliable voice communications.
Taking advantage of the advanced features of the Cisco SRW2048 can further secure the integrity of your network. The WebView interface provides an intuitive, highly secure management interface, enabling you to better utilize the comprehensive feature set of the switch for a better-optimized, more secure network.


• Forty-eight 10/100/1000 switched RJ-45 ports with automatic medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection

• 4 mini Gigabit Interface Converter (mini-GBIC) ports for fiber or copper interconnections

• Nonblocking, store-and-forward switching mechanism

• Simplified quality of service (QoS) management enabled by advanced queuing techniques using 802.1p, differentiated services (DiffServ), or type of service (ToS) traffic prioritization specifications

• Configuration and monitoring from a standard web browser with WebView management

• Secure remote management of the switch via Secure Shell (SSH) and SSL secure channel network protocols

• 802.1Q-based VLANs enable segmentation of networks for improved performance and security

• Private VLAN Edge (PVE) for simplified network isolation of guest connections or autonomous networks

• Automatic configuration of VLANs across multiple switches through Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP)

• Automatic port configuration through auto MDI/MDIX and 802.1ab (Link Layer Discovery Protocol [LLDP])

• User/network port-level security via 802.1X authentication and MAC-based filtering

• Increased bandwidth (up to 8x) and added link redundancy with Link Aggregation Control Protocol (LACP)

• Enhanced rate-limiting capabilities provide control, including back pressure to control the rate at which data can flow into and out of a port

• Broadcast, multicast, and unknown unicast storm control

• Port mirroring for noninvasive monitoring of switch traffic

• Jumbo frame support (10 KB)

• Simple Network Management Protocol (SNMP) versions 1, 2c, and 3 and Remote Monitoring (RMON) support

• Fully rack mountable using the included rack-mounting hardware
