Allows you to connect the switch to the network immediately, without configuration, “plug and play” principle; If there is no DHCP server on the network, the switch will switch to a unique static address mode, determined depending on the MAC address of the switch.
Supports FTP, TFTP and SFTP
p>
Various mechanisms for updating configurations; FTP supports two-way file exchange over a TCP/IP network; Trivial FTP (TFTP) is a simpler file transfer mechanism based on the UDP protocol; Secure File Transfer Protocol (SFTP) runs on top of the SSH tunnel for added security.
Remote Monitoring (RMON)
Use the standard SNMP protocol to monitor basic network functions; support for event, alarm, history and statistics groups, as well as private alarm extension groups.
Quality of Service (QoS) management
Traffic prioritization
Ensuring priority in forwarding time-sensitive packets (such as VoIP and video) over other traffic based on classification by DSCP or IEEE 802.1p; packets are distributed across eight hardware queues for more efficient use of bandwidth.
IEEE 802.1p/Q
Forwarding data to devices taking into account the priority and type of traffic; IEEE 802.1Q support.
Class of Service (CoS)
Tag assignment IEEE 802.1p priority based on IP address, Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ token.
Broadcast control
Ability to limit the rate of broadcast traffic to reduce unwanted multicast traffic on the network.
Service quality management based on extended classification
Traffic classification according to multiple criteria depending on level 2, 3 and 4 information; applying quality of service (QoS) policies, such as setting a priority level and limiting the rate of certain traffic at the individual port level.
Limiting the data transfer rate
Assignment of the maximum speed limit for incoming traffic at the port level and the minimum speed at the queue and port levels.
Powerful quality of service management capabilities
Supports the following congestion response mechanisms: Strict Priority Queue (SP), Weighted Round Robin (WRR), and SP+WRR.
Connections
IPv6
IPv6 Host
Ability to install and manage switches at the edge of an IPv6 network over this network.
IPv6 routing
Support for IPv6 static routes.< /p>
Monitor MLD traffic
Forward IPv6 multicast traffic to the appropriate interface to avoid flooding traffic propagation.
Access control lists (ACLs)/QoS for IPv6
Supports ACLs and QoS mechanisms for IPv6 network traffic.
IEEE 802.3X flow control
Support for mechanisms to slow down the flow when propagating over the network to avoid packet loss on an overloaded node.
Powering devices over twisted pair cable according to IEEE 802.3at (PoE+)
Up to 30 W per port, which provides support for the latest PoE+ devices, such as IP phones, wireless access points, CCTV cameras and any other IEEE 802.3af standard end devices; eliminates the cost of additional power and outlet wiring that would otherwise be required to install IP phones and wireless devices.
Cable Diagnostics
Remotely detect cable problems using a browser-based tool.
Flow control< /p>
IEEE 802.3x backpressure to reduce congestion during high traffic volumes.
Automatic MDI/MDI-X mode selection
Automatic adjustment to cable layout (standard/crossover) on all 10/100/1000 Mbps ports .
Security
Advanced access control lists (ACLs)
Ensures security by ensuring that only authorized users can access the web-based management interface.
Performance<
Automatic negotiation of half-duplex/full-duplex mode on each port
Doubles the throughput of each port.
Selectable queue settings
Improves performance by selecting the number of queues and corresponding buffer sizes to best suit the needs of network applications.
IGMP snooping
Improves network performance by filtering multicast traffic instead of flooding traffic to all ports.
Fiber optic backbone interfaces
Supports long-haul connections using Gigabit Ethernet fiber optic backbone interfaces.
Layer 2 switching
Spanning tree protocol (STP)
Supports IEEE 802.1D – Spanning Tree Protocol (STP), IEEE 802.1w – Fast Spanning Tree Protocol (RSTP) with faster convergence and IEEE 802.1s – Multiple Instance Spanning Tree Protocol (MSTP).
