Data Sheet 

● 

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 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. 

● 

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. 

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. 

Cisco 500 Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802.at), 

providing up to 30 watts per port. 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 802.11n wireless access points, video-based IP phones, 

surveillance cameras, and more. 

PoE capabilities simplify the deployment of advanced technologies by allowing you to connect and power 

network endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 

500 Series switches are also fully backwards compatible with IEEE 802.11af PoE and previous- 

generation Cisco legacy PoE protocols. 

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. 

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.
