•
Power over Ethernet easily and cost-effectively powers wireless access
points, video cameras, and other network-connected endpoints
•
Enhanced 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
Overview
The Cisco®
SRW2024P 24-Port Gigabit Switch (Figure 1) allows you to expand your
network securely. 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 minimize and
contain 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 SRW2024P 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, and Rapid STP (RSTP) 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 point 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 IEEE802.3af MIB for PoE,
IEEE 802.1d STP, IEEE 802.1w RSTP, Fast Linkover, and cable diagnostics.
Features
• Twenty-four 10/100/1000 switched RJ-45 ports deliver up to 2 Gbps of throughput per port
• Two shared 10/100/1000 mini Gigabit Interface Converter (mini-GBIC) ports
• Switching capacity delivers wire-speed performance at 48 Gbps nonblocking capacity
• WebView monitoring allows administrators to view the current status and configuration using their favorite web browser
•
PoE on twenty-four 10/100/1000 ports supplies up to 7.5W per port, or
on twelve 10/100/1000 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-4096 range
• Port trunking for up to 8 groups allows you to increase your bandwidth for each uplink or server connection
• Port configuration settings for link, speed, auto MDI/MDIX, 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 by providing features like Internet Group Management Protocol
(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)
•
Advanced security ACL can be a restricted-access network by denying or
rate-limiting based on L1-L4 information- for example, MAC address,
Ethernet type, VLAN ID, IP address, protocol ID, or TCP/UDP port
• Containment of storms - broadcast, multicast, and unknown unicast
• Expandability and availability increased across multiple switches using link aggregation
•
Port trunking for up to eight groups with up to eight ports per group
allows you to increase your bandwidth for each uplink or server
connection
• SNMP and RMON management expand your visibility options
