Auto-Check Checks the connection status of the PDs. Reboots the PDs if there are no responses. Power Delay The PoE ports can be delayed to turn on to protect the switch from overload. Non-Stop PoE, Soft Reboot The switch continues to supply power to the PDs even during soft reboot.

Layer3 functions	IPv4 and IPv6 Unicast: Static routing. RIP v1/v2: The Routing Information Protocol (RIP) is an internal routing protocol based on distance vector routing and used within an autonomous system. OSPF v2/v3: OSPF is a link-state routing protocol. It is designed for internal operation within a single autonomous system. Each OSPF router maintains an identical database that describes the topology of the autonomous system. A routing table is calculated from this database by constructing a shortest-path tree.
Communication redundancy	Standard Spanning Tree (STP), IEEE802.1d Rapid Spanning Tree (RSTP), IEEE802.w Multiple Spanning Tree (MSTP), IEEE802.1s
VLAN	Tag-based VLAN according to 802.1Q Supports up to 4K VLANs simultaneously (out of 4096 VLAN IDs) Port-based VLAN A port member of a VLAN can be isolated to other isolated ports of the same VLAN and private VLANs. 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 the same. Voice VLAN The Voice VLAN feature enables voice traffic to be forwarded on the Voice VLAN. Guest VLAN The IEEE 802.1X Guest VLAN feature allows a guest VLAN to be configured for each 802.1X port on the device to provide limited services to non-802.1X compliant clients. Q-in-Q (double tag) VLAN This allows you to specify specific requirements for VLAN IDs and the number of VLANs to be supported. 802.1v Protocol VLAN Classifying multiple protocols into a single VLAN often enforces VLAN boundaries that are inappropriate for some of the protocols. This requires a non-standard entity to forward frames containing protocols for which the VLAN boundaries are inappropriate between VLANs. MAC-based VLAN The MAC-based VLAN feature allows incoming untagged packets to be assigned to a VLAN, thus classifying traffic based on the packet's source MAC address. IP Subnet-based VLAN In an IP subnet-based VLAN, all end workstations on 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. Classification Port-based: Traffic QoS by port 802.1p: 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 priority (IPP) value or a DSCP (Differentiated Services Code Point) value. QoS supports the use of both values, as DSCP values are backward compatible with IP priority values. TCP/IP ACL classification and re-marking: QoS through ACL rate limiting Ingress policer Egress shaping and rate control per port Scheduling Strict priority and weighted round robin (WRR): Weighted round robin is a scheduling algorithm that uses the weights assigned to queues to determine how much data is emptied from one queue before being moved to the next queue.
Security	Certified authentication A private HTTPS key can be stored for management access. User management User rights can be freely configured at up to 15 levels. ACL The switch allows up to 512 entries. Drop or rate restriction based on source/destination MAC/IP address or VLAN ID. Rules and conditions for incoming packets can be defined for each port. The rules cover protocols, IP ports and address ranges. The rules can be defined either by authorization or exclusion. 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 Authorization 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 a client. Secure Shell (SSH) SSH secures Telnet traffic in or out of the switch, SSH v1 and v2 are supported Secure Socket Layer (SSL) SSL encrypts HTTP traffic, enabling advanced 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 is reflecting BPDUs back to the network. It enforces the boundaries of the STP domain and keeps the active topology predictable by preventing network devices behind a BPDU Guard-enabled port from participating in STP. DHCP Snooping: With DHCP Snooping, the switch provides a feature 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 limits 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 when no multicast router is present. 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, called a multicast VLAN, to forward multicast traffic across a Layer 2 network in conjunction with IGMP snooping.
