This layer 2/3 switch with extensive L3 functions was specially developed for applications with high data loads, such as video over IP, video streaming also in conjunction with multicast. The switch has extensive security functions that protect both the switch itself and the network traffic. The PoE allows IP cameras to be powered via the data cable. The compact design and reduced number of ports make this switch ideal for smaller installations or as a remote unit in a larger network. With its extensive management options, can also fulfil complex network requirements. Special features for access control Active monitoring of the components The switch continuously monitors components powered via PoE. In the event of a failure, the switch automatically restarts the controller . At the same time, the switch sends an SNMP message. Active monitoring of the PoE supply If, for example, a defective camera demands too much power from the switch , the switch sends an alarm via SNMP. If the separate PoE power supply fails, the switch continues to function and can alert the fault. Active management of the PoE power When the switch is started up, the individual PoE ports can be started up with a time delay to prevent the PoE power supply units from being overloaded. Active integration of the switch in video management systems SW modules are available for the popular Milestone and Siveillance Video video management systems that allow the switch management and DMS to be integrated directly into these VMS. Uninterrupted PoE power supply The PoE power supply to the PDs is not interrupted when the switch is rebooted. Jumbo frames even at 100 Mbit/s Jumbo frames up to 10,240 bytes are also supported at 100 Mbit/s . Further information Special features The switch has extensive security functions. For example, the ACL not only allows the switch itself to be protected, but also the traffic in the network. Non-stop PoE: When the switch is restarted, the PoE power supply to the connected cameras is not interrupted. As soon as the switch is operational again, so are the camera images. System notes The switch supports PTP, precision time protocol according to IEEE1588 v2 and IEC 61588. This function is used in industrial automation, in professional audio-video applications for audio-video bridging and in telecommunications, among others. DMS DMS (Device Management System) The switch has an integrated network monitoring and control system that gives the user a good overview of the entire network in a very simple way. This DMS system has the following features: Graphical network overview The network topology view provides a quick overview of all switches and end devices in the network, such as IP cameras or servers, with details of the IP address, device type and name. Maps and maps can be stored as background images, allowing the user to quickly access specific network devices even without knowledge of the IP structure. Device search This function also allows targeted access to a specific device in larger networks. Newly added devices, such as a replaced IP camera, are displayed immediately and allow the user to access immediately without knowing the IP address. Data traffic display The data traffic can be displayed graphically per port over a time axis. Error handling and security Network diagnostics between the master switch and connected end devices. Protection mechanisms such as data rate limiting provide effective protection against unauthorised access. IEEE802.3ah and IEEE802.1ag provide tools for structuring networks.

Private VLAN Edge (PVE) Private VLANs are based on the source port mask and there are no connections to VLANs. This means that VLAN IDs and private VLAN IDs can be identical. Voice VLAN The Voice VLAN function enables the forwarding of voice traffic on the Voice VLAN. Guest VLAN With the IEEE 802.1X guest VLAN function, a guest VLAN can be configured for any 802.1X port on the device to provide non-802.1X compliant clients with restricted services. Q-in-Q (double tag) VLAN This allows specific requirements for VLAN IDs and the number of VLANs to be supported to be set. 802.1v protocol VLAN The classification of multiple protocols into a single VLAN often enforces VLAN boundaries that are unsuitable for some of the protocols. This requires the presence of a non-standard unit that forwards the frames with the protocols for which the VLAN boundaries are unsuitable between VLANs . MAC-based VLAN The MAC-based VLAN function makes it possible to assign incoming untagged packets to a VLAN and thus classify the traffic based on the source MAC address of the packet. IP subnet-based VLAN In an IP subnet-based VLAN, all end workstations in an IP subnet are assigned to the same VLAN. In this VLAN, users can move their workstations without having to reconfigure their network addresses. Management VLAN Management VLAN is used to manage the switch from a remote location using protocols such as Telnet, SSH, SNMP, Syslog, etc. Link Aggregation IEEE 802.3ad LACP / Static Trunk, supports five groups of 16-port trunks or static trunks. QoS Hardware queue Supports eight hardware queues. Classification Port-based: Traffic QoS by port 802.1p: The VLAN priority-based Layer 2 CoS QoS class of service is a parameter used in data and voice protocols to differentiate the types of payloads contained in the transmitted packet. DSCP-based differentiated services (DiffServ) Layer 3 DSCP QoS: IP packets can carry either an IP precedence value (IPP) or a Differentiated Services Code Point (DSCP) value. QoS supports the use of both values, as DSCP values are downward compatible with IP priority values. Classification and re-labelling of TCP/IP ACLs: QoS through ACL Rate limiting Ingress policer Egress shaping and speed control per port Scheduling Strict priority and weighted round robin (WRR): Weighted Round Robin is a scheduling algorithm that uses the weights assigned to the queues to determine how much data is emptied from a queue before it is moved to the next queue . Security Certified authentication A private HTTPS key can be stored for management access. User administration User rights can be freely set in up to 15 levels . ACL The switch allows up to 512 entries. Drop or rate limiting based on source/destination MAC/IP address or VLAN ID. Rules and conditions for incoming packets can be defined per port. The rules include protocols, IP ports and address ranges. The rules can be defined using either the authorisation or the exclusion method . The criteria are TCP/ UDP source and destination ports, 802.1p priority, Ethernet type, ICMP packet (Internet Control Message Protocol). Port security MAC address management per port and IP source guard: The MAC address can be checked in combination with the IP address. Storm Control Prevents traffic in a LAN from being disrupted by a broadcast, multicast or unicast flood on a port. RADIUS authentication, 802.1X Authorisation and accounting, MD5 hash, guest VLAN, single/multiple host mode and single/multiple sessions Supports IGMP-RADIUS based 802.1X Dynamic VLAN assignment TACACS+ authentication The switch supports TACACS+ authentication. Switch as client. Secure Shell (SSH) SSH secures Telnet traffic to or from the switch, SSH v1 and v2 are supported Secure Socket Layer (SSL) SSL encrypts the HTTP traffic and thus enables extended secure access to the browser-based management GUI in the switch. HTTPS & SSL (Secured Web) Hyper Text Transfer Protocol Secure (HTTPS) is the secure version of HTTP. BPDU Guard The BPDU Guard, an extension of STP, removes a node that reflects BPDUs back into the network. It enforces the boundaries of the STP domain and keeps the active topology predictable by not allowing network devices behind a BPDU Guard-enabled port to participate in STP . DHCP Snooping With DHCP snooping, the switch has a function that acts as a firewall between untrusted hosts and trusted DHCP servers. Loop protection Loop protection prevents unknown unicast, broadcast and multicast loops in layer 2 switching configurations . Multicast IGMP v1/v2/v3 snooping IGMP restricts the bandwidth-intensive multicast traffic to the requesters. Supports 1024 multicast groups. IGMP Querier IGMP Querier is used to support a Layer 2 multicast domain of snooping switches if no multicast router is available. IGMP Proxy IGMP snooping with proxy reporting or report suppression actively filters IGMP packets to reduce the load on the multicast router. MLD v1/v2 Snooping Delivers IPv6 multicast packets only to the required recipients. Multicast VLAN Registration (MVR) A dedicated, manually configured VLAN, the so-called Multicast VLAN, to forward multicast traffic via a Layer 2 network in conjunction with IGMP snooping.

This layer 2/3 switch with extensive L3 functions was specially developed for applications with a high data load, such as video over IP, video streaming also in conjunction with multicast. The switch has extensive security functions that protect both the switch itself and the network traffic. The PoE allows IP cameras to be powered via the data cable. With the extensive management options, even complex network requirements can be fulfilled. The option of redundant power supply increases the availability of the switch. Special features for access control Active monitoring of the components Components powered by the switch via PoE are constantly monitored. In the event of a failure, the switch restarts the controller independently . If this is not successful, the switch sends an alarm message via SNMP. Active monitoring of the PoE supply If, for example, too much power is required from the switch due to a defective camera, the switch sends an alarm via SNMP. Active management of the PoE power When the switch is started up, the individual PoE ports can be started up with a time delay to prevent the PoE power supply from being overloaded . Further component-friendly features Extra high backplane performance for smooth transmission with full port utilisation. Jumbo frames up to 9600 bytes are also supported at 100 Mbit/s . Port security through MAC address restriction. Further information Special features The switch has extensive security functions. For example, the ACL not only allows the switch itself to be protected, but also the traffic in the network. Non-stop PoE: When the switch is restarted, the PoE power supply to the connected cameras is not interrupted. As soon as the switch is operational again, so are the camera images. System notes The switch supports PTP, precision time protocol according to IEEE1588 v2 and IEC 61588. This function is used in industrial automation, in professional audio-video applications for audio-video bridging and in telecommunications, among others. DMS DMS (Device Management System) The switch has an integrated network monitoring and control system, which gives the user a very simple overview of the entire network. This DMS system has the following features: Graphical network overview The network topology view provides a quick overview of all switches and end devices in the network, such as IP cameras or servers, with details of the IP address, device type and designation. Plans and maps can be stored as background images with which the user can quickly access specific network devices even without knowledge of the IP structure, Device search This function makes it possible to access a specific device even in larger networks. Newly added devices, such as a replaced IP camera, are displayed immediately and allow the user immediate access without knowledge of the IP address. Data traffic display The data traffic can be displayed graphically per port over a time axis . Error handling and security Network diagnostics between master switch and connected end devices. Protection mechanisms such as data rate limiting allow effective protection against unauthorised access. With IEEE802.3ah and IEEE802.1ag, tools are available for the structuring of networks.

Voice VLAN The Voice VLAN function enables the forwarding of voice traffic on the Voice VLAN. Guest VLAN With the IEEE 802.1X guest VLAN function, a guest VLAN can be configured for any 802.1X port on the device to provide non-802.1X compliant clients with restricted services. Q-in-Q (double tag) VLAN This allows specific requirements for VLAN IDs and the number of VLANs to be supported to be set. 802.1v protocol VLAN The classification of multiple protocols into a single VLAN often enforces VLAN boundaries that are unsuitable for some of the protocols. This requires the presence of a non-standard unit that forwards the frames with the protocols for which the VLAN boundaries are unsuitable between VLANs . MAC-based VLAN The MAC-based VLAN function makes it possible to assign incoming untagged packets to a VLAN and thus classify the traffic based on the source MAC address of the packet. IP subnet-based VLAN In an IP subnet-based VLAN, all end workstations in an IP subnet are assigned to the same VLAN. In this VLAN, users can move their workstations without having to reconfigure their network addresses. Management VLAN Management VLAN is used to manage the switch from a remote location using protocols such as Telnet, SSH, SNMP, Syslog, etc. Link Aggregation IEEE 802.3ad LACP / Static Trunk, supports five groups of 16-port trunks or static trunk QoS Hardware queue Supports eight hardware queues.
