Features amd Benefits:

Easy Deployment and Use

Cisco 500 Series switches are designed to be easy to use and manage by small businesses or the partners that serve them. They feature:

• Simple-to-use graphical interfaces reduce the time required to deploy, troubleshoot, and manage the network and allow you to support sophisticated capabilities without increasing IT head count.

• The switches also support Textview, a full command-line interface (CLI) option for partners that prefer it.

• Using Auto Smartports intelligence, the switch can detect a network device connected to any port and automatically configure the optimal security, quality of service (QoS), and availability on that port.

• Cisco Discovery Protocol (CDP) discovers Cisco devices and allows devices to share critical configuration information, simplifying network setup and integration.

• Support for Simple Network Management Protocol

Power over Ethernet Plus (PoE+): 

The Cisco SG500X-48P Switches is equipped with 48 PoE+ ports with a budget of 375W. This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly, and at a lower cost. The Cisco SG500X-48P supports IEEE 802.3at PoE+.
The power is managed in a smart fashion such that only the amount of power the endpoint needs is delivered to it and not wasted. As a result, the switches can support devices that require more power, such as dual-band 802.11nwireless access points, video-based IP phones, surveillance cameras, and more.

High Reliability and Resiliency

In a growing business where 24x7 availability is critical, you need to assure that employees can always access the data and resources they need. In these environments, stackable switches can play an important role in eliminating downtime and improving network resiliency. For example, if a switch within a Cisco 500 Series stack fails, another switch immediately takes over, keeping your network up and running. You can also replace individual devices in the stack without taking your network offline or affecting employee productivity.
The Cisco 500X models provide an additional layer of resiliency with support for the Virtual Router Redundancy Protocol (VRRP). VRRP lets you extend the same resiliency that stacking provides for individual switches to complete network domains. By running VRRP between two stacks, you can instantly cut over from one stack to another in the event of a problem, and continue operating even after a failure.
The Cisco 500 Series also supports dual images, allowing you to perform software upgrades without having to take the network offline or worry about the network going down during the upgrade.

Simplified IT Operation

Cisco 500 Series switches help optimize your IT operations with built-in features that simplify and streamline day-to-day network operation:

• True stacking allows you to troubleshoot, configure, and manage multiple physical switches as a single entity.

• Unlike other stacking switches that require uniform configurations, the Cisco 500 Series allows you to mix Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet models in a single stack, providing total flexibility without sacrificing manageability.

• Cisco switchesuse common chipsets/software across all switching portfolios, so all Cisco switcheswithin a category support the same feature set – making it easier to manage and support all switches across the network.

True Stacking

Some switches claim to support stacking but in practice support only “clustering” – meaning that each switch must still be managed and configured individually. Cisco 500 Series switches provide true stacking capability, allowing you to configure, manage, and troubleshoot all switches in a stack as a single unit, with a single IP address.
A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility, scalability, and ease of use since the stack of units operate as a single entity constituting all the ports of the stack members. This capability can radically reduce complexity in a growing network environment while improving the resiliency and availability of network applications. True stacking also provides other cost savings and administrative benefits through features such as cross-stack QoS, VLANs, and port mirroring, which clustered switches can’t support.

Strong Security

Cisco 500 Series switches provide the advanced security features you need to protect your business data and keep unauthorized users off the network:

• Embedded Secure Sockets Layer(SSL) encryption protects management data traveling to and from the switch.

• Extensive access control lists (ACLs) restrict sensitive portions of the network to keep out unauthorized users and guard against network attacks.

• Guest VLANs let you provide Internet connectivity to non-employee users while isolating critical business services from guest traffic.

• Support for advanced network security applications such as IEEE 802.1Xport security tightly limits access to specific segments of your network. Web based authentication provides a consistent interface to authenticate all types of host devices and operating systems, without the complexity of deploying IEEE 802.1Xclients on each endpoint.

• Advanced defense mechanisms, including dynamic Address Resolution Protocol (ARP) inspection, IP Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate network attacks. Combinations of these protocols are also referred to as IPMB (IP-MAC- port binding)

• IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite includes ND inspection, RA guard, DHCPv6 guard and neighbor binding integrity check, providing unparalleled protection against a vast range of address spoofing and man in the middle attack on IPv6networks.

• Time based ACLs and Port Operation restrict access to the network during predesignated times, such as business hours.

• Uniform MAC address-based security can be applied automatically to mobile users as they roam between wireless access points.

• Secure Core Technology (SCT) helps ensure that the switch is able to process management traffic in the face of a denial of service attack.

• Private VLANEdge (PVE) provides Layer 2isolation between devices on the same VLAN.

• Storm control can be applied to broadcast, multicast, and unknown unicast traffic.

• Protection of management sessions using Radius, TACACS+ and local database authentication as well as secure management sessions over SSL, SSH, and SNMPv3.

• DoS (denial-of-service) attack prevention maximizes network uptime in the presence of an attack.

Networkwide Automatic Voice Deployment

Using a combination of CDP, LLDP-MED, Auto Smartports, and VSDP (Voice Services Discovery Protocol – a unique Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge around a single voice VLAN and QoS parameters and then propagate them out to the phones on the ports where they are discovered. For example, automated voice VLAN capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to prioritize voice traffic.

IPv6 Support

As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 500 Series can support the transition to the next generation of networking and operating systems such as Windows 7, Vista, and Linux. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6 standard at your own pace, and helping ensure that your current network will continue to support your business applications in the future. Cisco 500 Series switches have successfully completed rigorous IPv6 testing and have received the USGv6 and IPv6 Gold certification.

Advanced Layer 3 Traffic Management

The Cisco 500 Series enables a more advanced set of traffic management capabilities to help growing businesses organize their networks more effectively and efficiently. For example, the switches provide static LAN Layer 3 routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading application performance.
With these capabilities, you can boost the efficiency of your network by offloading internal traffic-handling tasks from your router and allowing it to manage primarily external traffic and security.
Cisco 500X models go even farther, providing dynamic Layer 3 routing features. With these capabilities, you can minimize the need to manually configure routing devices and simplify the ongoing operation of the network.

The Cisco SF500-24 is a 24-port stackable managed 10/100 switch with four Gigabit Ethernet ports - 2 combination ports and 2 Small Form-Factor Pluggable (SFP) ports - that provides a solid foundation for your current business applications, as well as those you are planning for the future. It offers true stacking, advanced security, quality of service, energy-saving technology (EEE), IPV6, and network features that deliver the reliability and performance needed by demanding environments. The switch is easy to configure and manage with a choice of management tools. The Cisco SF500-24 provides the ideal technology foundation at a price you can afford, and in a solution designed to grow with your business.
