Jumbo frames support	Yes
LED indicators A list of the functions or statuses that an LED indicator on a device can display, such as power status, activity, link, and other operational signals.	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.	16000 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.	Telnet, SNMP v1/v2c/v3
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.	1 Gbit/s
Multicast support Indicates whether the device can send or receive IP multicast traffic, allowing it to participate in group communications such as streaming media, IPTV, and certain network protocols that rely on multicast distribution.	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
Noise level The sound intensity produced by a product, expressed in decibels (dB) or sones. It indicates how loud the device is during operation and helps users assess suitability for quiet environments.	48.6 dB
Package depth The linear measurement from front to back or top to bottom of a product’s packaging, expressed in a physical unit such as millimeters, centimeters, inches, etc. It indicates how deep the packaged item is and can be used for fitting, compatibility, or spatial planning.	568 mm
Package Height The vertical dimension of a product’s packaging measured from its lowest to highest point. It is expressed in a physical unit such as millimetres, centimetres or inches and helps customers assess how tall the package will be when stored or shipped.	157 mm
Package width The horizontal measurement of a product’s packaging, expressed in a linear unit such as millimetres or inches. It indicates how wide the package is from one side to the other and helps customers assess fit for storage, shipping, or display.	530 mm
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
Pallet length The linear dimension of a pallet measured in a standard unit such as meters, centimeters or inches. It represents the overall length from one end to the other and is used to compare the size of pallets across different products and logistics contexts.	110 cm
Pallet width The horizontal measurement of a pallet, expressed in a linear unit such as millimetres or inches. It indicates how wide the pallet is from one side to the other and helps customers assess fit for storage, shipping, or display.	120 cm
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 LED	Yes
Safety A list of safety and regulatory certifications that a product complies with, such as CE, UL, FCC, or other regional standards.	CB, cUL, LVD
