Auto Surveillance VLAN (ASV)
Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Voice Services Discovery Protocol (VSDP) delivers networkwide zero-touch deployment of voice endpoints and call control devices
Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) Enable automatically propagation and configuration of VLANs in a bridged domain
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping Limits bandwidth-intensive multicast traffic to only the requesters; supports 255 multicast groups (source-specific multicasting is also supported)
IGMP querier Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
Head-of-Line (HOL) blocking HOL blocking prevention
Loopback detection Provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP
Layer 3 routing IPv4 routing Wire-speed routing of IPv4 packets
Up to 32 static routes and up to 16 IP interfaces
IPv6 routing Wire-speed routing of IPv6 packets
Layer 3 interface Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
Classless Interdomain Routing (CIDR) Support for CIDR
Dynamic Host Configuration Protocol (DHCP) relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BootP)/DHCP packets
Security Secure Sockets Layer (SSL) Encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch
SSH Protocol SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported.
IEEE 802.1X (authenticator role) RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
Secure Core Technology (SCT) Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received
Secure Sensitive Data (SSD) A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices and a secure auto-configuration. Access to view the sensitive data as plain text or encrypted is provided according to the user-configured access level and the access method of the user
Trustworthy systems Trustworthy systems provide a highly secure foundation for Cisco products
Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])

2-Port Dual-Monitor HDMI KVM Switch
The Manhattan 2-Port Dual-Monitor HDMI KVM Switch is a compact solution for providing access and control over two HDMI/USB-equipped computers from a single keyboard and mouse and up to two monitors. It helps save you time on installation with its included combo cables — there s no need to purchase additional ones — that easily connect directly to the system.
Easy to use for improved efficiency This KVM Switch helps you access your systems more efficiently without the expense and clutter of extra keyboards, mice, and monitors. You select your connected computers and audio/mic channels through the front-panel push-buttons or keyboard hotkeys. The enhanced control this KVM switch provides is ideal for high graphical content in applications like video editing, digital signage server control, medical imaging, multimedia design or dual system control workstations. It is also great for sharing two multimedia PCs or notebooks with a single HDMI TV.
4K resolution at 30 Hz and full audio support The ever-growing demand for higher video quality and the evolution of HDMI technology has put 4K-enabled computers and displays in many visually ambitious workplace and commercial applications. Supporting up to 3840 x 2160 (4K) resolution at 30 Hz, this KVM Switch is right at home in your Ultra-High-Definition-equipped setup. You can connect a second monitor to enjoy maximized viewing. You also get full audio compatibility, with support for digital audio and separate analog 3.5 mm stereo audio jacks for microphones and speakers or headphones.
Additional USB hub port The integrated USB 2.0 hub offers a front-facing USB-A port in addition to keyboard and mouse ports. This hub port works among your attached computers as if it were directly connected to your host computer so you can avoid having to constantly plug/unplug devices such as printers, storage drives or scanners.
Compatible with Windows, Mac, Linux and more Being OS independent, this HDMI KVM switch not only supports Windows, Mac OS and Linux, but it is also compatible with Unix and even Novell NetWare to fully support older legacy hardware.
