Growing businesses require cost-effective networking solutions that can scale to meet ever-changing business needs. The Cisco® SRW208L 8-Port 10/100 Ethernet Switch (Figure 1) brings a new level of intelligence and security to the network infrastructure. Its intelligence and small size make it ideal for a conference room or training room where security and uptime are important. It offers a mini Gigabit Interface Converter (mini-GBIC) port and a 100-Mbps intermediate-reach optical interface for connection to a core switch.
Network security is a top priority in any size business. Most business data networks, large and small, are unsecured. Unauthorized access to the network and mission-critical data is a constant concern. The Cisco SRW208L is able to secure the network through 802.1X port authentication and MAC-based filtering. 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 quality of service (QoS) and traffic management features in the Cisco SRW208L, voice data can be prioritized, helping ensure clear and reliable voice communications.
Enabling the advanced features of the Cisco SRW208L further secures 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, resulting in a better-optimized, more secure network.
Features
• Eight 10/100 switched RJ-45 ports deliver up to 200 Mbps of throughput per port
• One mini-GBIC port
• One 100BASE-LX uplink port with LC-type connector and built-in transceiver
• Simplified 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 medium dependent interface (MDI) and MDI crossover (MDI-X) detection
• User/network port-level security via 802.1X authentication and MAC-based filtering
• Increased bandwidth (up to 8x) and link redundancy with Link Aggregation Control Protocol (LACP)
• Enhanced rate-limiting capabilities and storm control, including multicast, broadcast, and flood control
• Port mirroring for noninvasive monitoring of switch traffic
Embedded Remote Monitoring (RMON) software agent supports four RMON groups (history, statistics, alarms, and events) for enhanced traffic management, monitoring, and analysis.
Firmware upgrade
Web browser upgrade (HTTP) and Trivial File Transfer Protocol (TFTP)
Port mirroring
Traffic on a port can be mirrored to another port for analysis with a network analyzer or RMON probe.
