Cisco SRW224G4P 24-Port 10/100 + 4-Port Gigabit
Switch: WebView/PoE
Cisco Small Business Managed Switches
Secure, Intelligent Switch with PoE for Growing Small Businesses
Highlights
●Connects up to 24 network devices - PCs, printers, and servers - to share and transfer files
and videos across your network
●Power over Ethernet easily and cost-effectively powers wireless access points, video
cameras, and other network-connected endpoints
●Simplified, web-based management for easy installation and configuration
●Strong security protects network traffic to keep unauthorized users off the network

Product Overview
The Cisco SRW224G4P 24-Port 10/100 + 4-Port Gigabit Switch (Figure 1) offers a highly secure
way to expand your network. Web-based configuration of the switch is secured using SSL. User
access is verified using 802.1X security with a RADIUS authentication mechanism and can also be
controlled using MAC-based filtering.
Extensive quality of service (QoS) features make the solution ideal for real-time applications such
as voice and video. The four priority queues, together with the weighted round-robin and strict
priority scheduling techniques, facilitate efficient coexistence of real-time traffic with data traffic,
allowing each to meet its QoS needs. Individual users or applications can be prioritized above
others using various class of service options - by port, Layer 2 priority (802.1p), and Layer 3
priority (type of service [ToS] or differentiated services code point [DSCP]). Intelligent broadcast
and multicast storm control minimizes and contains the effect of these types of traffic on regular
traffic. Internet Group Management Protocol (IGMP) snooping limits bandwidth-intensive video
traffic to only the requestors without flooding all users. Incoming traffic can be policed and
outgoing traffic can be shaped, allowing you to control network access and traffic flow.
Other features of the Cisco SRW224G4P allow you to expand and grow your network of switches.
Link aggregation allows multiple high-bandwidth trunks between switches to be set up. This also
provides reliability, in that the system continues to operate if one of the links breaks. Spanning
Tree Protocol (STP), Fast STP, Rapid STP (RSTP), and Multiple STP (MSTP) allow you to build a
mesh of switches, increasing the availability of the system.

The rich features of the WebView management software include Simple Network Management
Protocol (SNMP), Remote Monitoring (RMON), Telnet, and HTTP management options, allowing
you to flexibly integrate and manage these devices in your network.
Automatic load sensing in the power control circuitry automatically detects Power over Ethernet
(PoE) on the access points before providing power. Power feeding of Ethernet is limited for fixed
10BASE-T/100BASE-TX ports. The switch can provide maximum output power per PoE port up to
15.4W on 12 ports or 7.5W on 24 ports simultaneously. Each port has independent overload and
short-circuit protection, with LED indicators for power status. The switch also supports IEEE
802.3af MIB for PoE, IEEE 802.1d STP, IEEE 802.1w RSTP, Fast Linkover, and IEEE 802.1s
MSTP. Cable diagnostics can be performed using the switch’s WebView utility.
Features
●Twenty-four 10/100 switched RJ-45 ports deliver up to 4 Gbps of throughput per port

●WebView monitoring allows administrators to view the current status and configuration
using their favorite web browser
●PoE on twenty-four 10/100 ports supplies up to 7.5W per port, or on twelve 10/100 ports
supplies up to the IEEE 802.3af maximum of 15.4W per port
●Automatic medium dependent interface (MDI) and MDI crossover (MDI-X) cable detection
●Port-based and 802.1Q-based VLANs support up to 256 VLANs
●Port trunking for up to eight groups allows you to increase your bandwidth for each uplink or
server connection
●Port configuration settings for link, speed, auto MDI/MDI-X, flow control, and more
●Fully rack mountable using the included rack-mounting hardware
●MAC address table supports up to 8000 MAC address entries
●Optimal platform to support real-time applications such as voice and video, with features
like IGMP snooping, multiple queues (4) with appropriate scheduling techniques,
prioritization of traffic based on port, 802.1p, IP ToS/precedence/DSCP, TCP/ User
Datagram Protocol (UDP) port, and line rate forwarding mechanisms
●Enhanced QoS functions including rate limiting for ingress/egress and per flow at 64 kbps
granularity
●Secure control via SSH for Telnet interface and SSL for HTTP interface
●User/network security via 802.1X (with RADIUS authentication) and MAC-based filtering
●Advanced security ACL can deny or limit network access based on Layer 1 through Layer 4
information - for example, MAC address, Ethernet type, VLAN ID, IP address, protocol ID,
or TCP/UDP port
●Containment of storms - broadcast and multicast
●Expandability and availability increased across multiple switches using link aggregation
●Port trunking for up to eight groups with up to eight ports per group, allowing you to
increase your bandwidth for each uplink or server connection
●SNMP and RMON management expand your visibility options
