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.

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 Shell (SSH) Protocol SSH is a secure replacement for Telnet traffic. Secure Copy Protocol (SCP) also uses SSH. SSH v1 and v2 are supported
Secure Sockets Layer (SSL) SSL support: Encrypts all HTTPS traffic, allowing highly secure access to the browser-based management GUI in the switch
IEEE 802.1X (authenticator role) 802.1X: RADIUS authentication and accounting, MD5 hash, guest VLAN, unauthenticated VLAN, single/multiple host mode, and single/multiple sessions
Supports time-based 802.1X, dynamic VLAN assignment, and MAC authentication
IEEE 802.1X supplicant A switch can be configured to act as a supplicant to another switch. This enables extended secure access in areas outside the wiring closet (such as conference rooms)
Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops
STP Root Guard Prevents edge devices not in the network administrator’s control from becoming STP root nodes
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
DHCP snooping Filters out DHCP messages with unregistered IP addresses and/or from unexpected or untrusted interfaces. This prevents rogue devices from behaving as DHCP servers
IP Source Guard (IPSG) When IPSG is enabled at a port, the switch filters out IP packets received from the port if the source IP addresses of the packets have not been statically configured or dynamically learned from DHCP snooping. This prevents IP address spoofing
Dynamic ARP Inspection (DAI) The switch discards ARP packets from a port if there are no static or dynamic IP/MAC bindings or if there is a discrepancy between the source or destination addresses in the ARP packet. This prevents man-in-the-middle attacks
IP/MAC/port binding (IPMB) The preceding features (DHCP snooping, IPSG, and DAI) work together to prevent Denial-of-Service (DoS) attacks in the network, thereby increasing network availability

Quick start guide: Quick start guide
Switching capacity and forwarding rate (All switches are wire speed and nonblocking) Capacity in Millions of Packets per Second (mpps) (64-byte packets) 77,38
Switching Capacity in Gigabits per Second (Gbps) 104
Layer 2 switching Spanning Tree Protocol (STP) Standard 802.1d Spanning Tree support
Fast convergence using 802.1w (Rapid Spanning Tree [RSTP]), enabled by default
Multiple Spanning Tree instances using 802.1s (MSTP); 8 instances are supported
Per-VLAN Spanning Tree Plus (PVST+) and Rapid PVST+ (RPVST+); 126 instances are supported
Port grouping/link aggregation Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP)
Up to 8 groups
Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad link aggregation
VLAN Support for up to 4,094 VLANs simultaneously
Port-based and 802.1Q tag-based VLANs; MAC-based VLAN; protocol-based VLAN; IP subnet-based VLAN
Management VLAN
Private VLAN with promiscuous, isolated, and community port
Private VLAN Edge (PVE), also known as protected ports, with multiple uplinks
Guest VLAN, unauthenticated VLAN
Dynamic VLAN assignment via RADIUS server along with 802.1x client authentication
CPE VLAN
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 network wide zero-touch deployment of voice endpoints and call control devices
Multicast TV VLAN Multicast TV VLAN allows the single multicast VLAN to be shared in the network while subscribers remain in separate VLANs. This feature is also known as Multicast VLAN Registration (MVR)
VLAN Translation Support for VLAN One-to-One Mapping. In VLAN One-to-One Mapping, on an edge interface customer VLANs (C-VLANs) are mapped to service provider VLANs (S-VLANs) and the original C-VLAN tags are replaced by the specified S-VLAN
Q-in-Q VLANs transparently cross a service provider network while isolating traffic among customers
Selective Q-in-Q Selective Q-in-Q is an enhancement to the basic Q-in-Q feature and provides, per edge interface, multiple mappings of different C-VLANs to separate S-VLANs
Selective Q-in-Q also allows configuring of Ethertype (Tag Protocol Identifier [TPID]) of the S-VLAN tag
Layer 2 protocol tunneling over Q-in-Q is also supported
Generic VLAN Registration Protocol (GVRP)/Generic Attribute Registration Protocol (GARP) Generic VLAN Registration Protocol (GVRP) and Generic Attribute Registration Protocol (GARP) enable automatic propagation and configuration of VLANs in a bridged domain
Unidirectional Link Detection (UDLD) UDLD monitors physical connection to detect unidirectional links caused by incorrect wiring or cable/port faults to prevent forwarding loops and black holing of traffic in switched networks
Dynamic Host Configuration Protocol (DHCP) Relay at Layer 2 Relay of DHCP traffic to DHCP server in different VLAN; works with DHCP Option 82
Internet Group Management Protocol (IGMP) versions 1, 2, and 3 snooping IGMP limits bandwidth-intensive multicast traffic to only the requesters; supports 2K multicast groups (source-specific multicasting is also supported)
IGMP Querier IGMP querier is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router
IGMP proxy The IGMP proxy provides a mechanism for multicast forwarding based on IGMP membership information without the need for more complicated multicast routing protocols.
Head-of-Line (HOL) blocking HOL blocking prevention
Loopback Detection 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
