Description
Cisco SG500-52 Dubai
The Cisco SG500-52 Dubai is meticulously crafted to safeguard your technology investment throughout the evolution of your business. With genuine stacking capability, this switch enables you to configure, manage, and troubleshoot multiple physical switches as a unified device, simplifying the expansion of your network. Notably, the Cisco 500 Series offers fanless models, marking it as one of the industry’s pioneering stackable switches. This innovative design enhances reliability, power efficiency, and reduces noise levels, contributing to an optimal networking experience.
A true stack provides a unified data and control plane, along with a management plane, offering flexibility, scalability, and ease of use as the stack operates as a single entity, encompassing all ports of the stack members. The Cisco SG500-52 Dubai switch goes beyond by safeguarding your technology investment through an enhanced warranty, dedicated technical support, and the future-proof ability to upgrade equipment and receive credit for your Cisco 500 Series switch. In essence, the Cisco SG500-52 Dubai establishes an ideal technology foundation for a growing business.
Features
Simple Use and Deployment
Cisco SG500-52 Dubai switch is designed to be easy to use and manage by small businesses or the partners that serve them. It has the following features:
- 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.
- You can manage the switches as individual devices or use Cisco Configuration Assistant (CCA) to discover, configure, and manage all Cisco devices in the network.
- 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 (SNMP) allows you to set up and manage your switches and other Cisco devices remotely from a network management station, improving IT workflow and mass configurations.
- The Cisco FindIT utility, which works through a simple toolbar on the user’s web browser, discovers Cisco devices in the network and displays basic information, such as serial numbers and IP addresses, to aid in configuration and deployment. (For more information, and to download this free utility, please visit www.cisco.com/go/findit.)
High Reliability and Resiliency
The Cisco SG500-52 Dubai switch 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 SG500-52 Dubai switch 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.
Easy Management
The Cisco SG500-52 Dubai switch helps 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, Cisco SG500-52 Dubai allows you to mix Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet models in a single stack, providing total flexibility without sacrificing manageability.
- Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches within a category support the same feature set – making it easier to manage and support all switches across the network.
True Stacking
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
The Cisco SG500-52 Dubai provides 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 nonemployee users while isolating critical business services from guest traffic.
- Support for advanced network security applications such as IEEE 802.1X port security tightly limits access to specific segments of your network. © 2011–2012 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public Information. Page 4 of 16 Data Sheet
- 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-MACport binding)
- Time based VLANs 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 VLAN Edge (PVE) provides Layer 2 isolation between devices on the same VLAN.
- Storm control can be applied to broadcast, multicast, and unknown unicast traffic.
