Connectivity technology The network and data interface technologies supported by the product, such as Wired, Wireless, USB, Bluetooth, or combinations thereof. Each value represents a distinct technology that can be used for communication or power delivery.	Wired
Copper ethernet cabling technology A comma‑separated list of the copper Ethernet standards supported by a device, such as 10BASE‑T, 100BASE‑TX, or 1000BASE‑T. Each entry indicates a specific speed and physical specification that the product can transmit over its RJ‑45 ports.	1000BASE-T,100BASE-T,10BASE-T
Data transfer rate The maximum theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. It represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.	1000 Mbit/s
DHCP features A comma‑separated list of the DHCP roles and options that a device can provide or use, such as server, client, relay, snooping, option 82 support, and IPv6 variants. The value may contain multiple items for a single product.	DHCP server,DHCP client
Flow control support Indicates whether a device includes hardware or firmware that can manage the flow of data on its interfaces, such as enabling or disabling automatic pause frames, handling congestion, or providing other traffic‑control mechanisms. A value of "Yes" means the feature is present and can be configured; "No" indicates it is not available.	Yes
Full Duplex Indicates whether a device can transmit and receive data simultaneously on two channels, allowing bidirectional communication without delay. A value of "Yes" means the device supports full‑duplex operation; a value of "No" indicates it operates only in half‑duplex mode.	Yes
IGMP snooping	Yes
Input frequency The frequency of the alternating current supplied to a power supply or charger, expressed in hertz (Hz). It indicates the acceptable operating range for the electrical mains that powers the device, ensuring proper functionality and safety.	50/60 Hz
Input voltage The range of alternating current voltage that a charger or power supply can accept, expressed in volts (V). It specifies the minimum and maximum input voltages compatible with the device.	100 - 240 V
Jumbo frames support	Yes
Link aggregation Indicates whether the device can combine multiple network connections into a single logical link to increase bandwidth or provide redundancy.	Yes
MAC address table The total count of unique MAC addresses that the device can store in its forwarding table. This value indicates how many devices can be simultaneously connected before the switch must start discarding or aging out older entries.	32000 entries
Management protocols A list of network protocols that a device can use for configuration, monitoring and remote management, such as SNMP, HTTP/HTTPS, Telnet, SSH or other standard interfaces. Each protocol is represented by its common name and may be separated by commas or slashes in the source data.	SNMP
Maximum data transfer rate The highest theoretical speed at which a device can send or receive data, expressed in bits per second (bps) or its multiples such as kbps, mbps, gbps, etc. This value represents the upper bound of throughput under optimal conditions and is useful for comparing performance across devices and interfaces.	10 Gbit/s
MIB support	Yes
Networking features A list of the networking protocols and standards that a device can support or comply with, such as IEEE 802.11 variants for wireless, IEEE 802.3 for Ethernet, or other relevant networking specifications. The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.	Gigabit Ethernet
Packet buffer memory The amount of temporary storage that a device allocates in its internal memory for buffering data before processing or forwarding it. Expressed as a digital capacity (e.g., kilobytes, megabytes), this value indicates how much information the hardware can hold at once and influences performance when handling high‑throughput or bursty traffic.	2 MB
Port mirroring Indicates whether the device supports port mirroring, a feature that allows one or more ports to copy traffic from another port for monitoring or analysis purposes.	Yes
Power supply type The type of electrical supply that powers the device, such as mains AC, DC, USB, battery, or a combination of these options.	AC
SFP+ module slots quantity The total count of Small Form‑factor Pluggable (SFP+) ports available on a networking device, such as switches or routers. Each port can accept an SFP+ transceiver module for fiber or copper connections. The value is a whole integer indicating how many separate SFP+ interfaces the product provides.	4
SFP/SFP+ slots quantity The total count of Small Form‑factor Pluggable Plus (SFP+) ports available on a networking device, such as switches or routers. Each port can accept an SFP+ transceiver module for high‑speed fiber or copper connections, typically supporting 10 Gb/s or higher. The value is a whole integer indicating how many separate SFP+ interfaces the product provides.	8
Spanning Tree Protocol Indicates whether the device implements the Spanning Tree Protocol (STP), a network protocol that prevents loops in Ethernet topologies by dynamically blocking and forwarding paths to maintain a loop‑free logical topology.	Yes
SSH/SSL support Indicates whether the device can establish secure connections using SSH or SSL protocols, allowing encrypted remote management and data transfer.	Yes
Supported data transfer rates	10/100/1000 Mbps
Supported network protocols A list of network communication protocols that a device can use or support, such as TCP/IP, HTTP, HTTPS, FTP, DHCP, DNS, and various wireless standards. Each protocol is represented by its standard name and may be separated by commas or slashes in the source data.	IPv4/IPv6
Switch layer The network layer(s) that a device can operate at, expressed as a string such as "L2", "L3" or combinations like "L2/L3". This attribute indicates the protocol stack level supported by the hardware or firmware.	L3
Switch type The classification of a network switch based on its management capabilities, such as Managed or Unmanaged. This attribute indicates whether the device can be configured and monitored remotely (Managed) or operates with fixed settings without remote configuration (Unmanaged). It helps users choose a switch that matches their networking expertise and control requirements.	Managed
Switching capacity The maximum data transfer rate that the device can handle, expressed as a numeric value with an appropriate unit such as Gbit/s or Mbit/s.
