Cisco SG250-26-K9

A list of authentication mechanisms that a network device can use to verify users or devices, such as Guest VLAN, Port-based authentication, MAC-based authentication, Web-based authentication, Captive Portal, and Auto VLAN. The values are comma‑separated strings representing each supported method.

Indicates the total count of physical RJ‑45 Ethernet connectors available on a device for wired network connectivity. The value is an integer representing how many separate ports can be used to connect Ethernet cables.

A list of the cable types that are supplied with the product, such as USB, HDMI, VGA, DisplayPort, LAN (RJ‑45), SATA, audio or other relevant connectors.

The colour or combination of colours that a product is available in, expressed as common names such as "Black", "Silver" or comma‑separated lists like "Black, White". It indicates the visual appearance of the item for consumers.

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.

The total amount of internal flash memory available in a device, expressed as a data size (e.g., megabytes or gigabytes). This attribute indicates how much data can be stored on the device’s built‑in flash storage and is useful for comparing storage capacity across products.

Indicates whether the product implements mechanisms to prevent head‑of‑line (HOL) blocking, a network performance issue where a single packet or flow delays subsequent traffic on the same path. A value of "Yes" means the device includes such mitigation features; "No" indicates it does not.

The total amount of internal memory available in a device, expressed as a data size such as megabytes (MB) or gigabytes (GB). It indicates how much information the component can hold for active processes and affects multitasking performance.

The largest Ethernet frame size in bytes that the device can transmit or receive without fragmentation. This value determines the maximum payload that can be sent in a single network packet, which can improve throughput for high‑bandwidth applications.

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.

The total count of distinct multicast groups whose traffic is filtered by the device. This value indicates how many separate multicast group addresses are actively blocked or managed, providing insight into network filtering capabilities.

The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

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.

Indica los estándares o velocidades que soportan los puertos RJ‑45 presentes en el producto, como Fast Ethernet (10/100 Mbps), Gigabit Ethernet (1 Gbps) o 10 Gigabit Ethernet. Cada valor describe una capacidad específica del conector y permite comparar la compatibilidad de red entre dispositivos.

A list of cryptographic and authentication methods that a device can use for secure communication or data protection. Each entry represents a distinct algorithm or protocol, such as encryption ciphers (e.g., AES, WEP), authentication mechanisms (e.g., RADIUS, WPA‑PSK), or network security protocols (e.g., HTTPS, SSL/TLS). The values are typically separated by commas and may include both technical identifiers and consumer‑friendly labels.

The range of temperatures in which a device can safely operate without risk of damage or performance degradation. Values are expressed in degrees Celsius (°C) and may represent a single temperature, a minimum–maximum interval, or an average operating point.

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.

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.

A list of network switching protocols that the device can use or support, such as STP, RSTP, MSTP, LACP, IGMP, and related link‑layer protocols. The value is a comma‑separated string of protocol names, allowing users to see which switching mechanisms are available on the product.
