Суич HP 1810-24G (J9803A), 24Port Gigabit Суич + 2x Gigabit SFP

HP 1810

Connectivity
Auto-MDI/MDIX: automatically adjusts for straight-through or crossover cables on all ports
Packet storm protection: protects against broadcast, multicast, or unicast storms with user-defined thresholds

IEEE 802.3af PoE-powered device option: obtains power provided by a standard PoE device connected to Port 1; deploy the switch wherever an Ethernet cable can reach as a power outlet is not needed (8-port GbE model only)

SFP ports for fiber connectivity: provides fiber connections for uplinks and other connections across longer distances than what copper cabling can support; "true" SFP ports operate in addition to available copper Ethernet ports, providing a higher total number of available ports vs. "combo" ports which are either a copper or fiber connection

Performance

Half-/full-duplex auto-negotiating capability on every port: doubles the throughput of every port
Link aggregation (trunking): brings together groups of ports automatically using Link Aggregation Control Protocol (LACP) or, manually, to form an ultra-high-bandwidth connection to the network backbone; helps prevent traffic bottlenecks; the 8-port models have four trunks of four links each, the 24-port models have eight trunks of four links each, and the 1810-48G switch has 16 trunks of eight links each

Quality of Service (QoS)

Traffic prioritization (IEEE 802.1p): allows real-time traffic classification witheight priority levels mapped to four queues

IEEE 802.1p prioritization with DSCP: delivers data from the switch to devices based on the priority and type of traffic using Differentiated Services Code Point (DSCP); available only with v2 switch models
Broadcast control: allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic

Layer 2 switching
VLAN support and tagging: supports up to 64 port-based VLANs and dynamic configuration of IEEE 802.1Q VLAN tagging, providing security between workgroups
Jumbo packet support: improves the performance of large data transfers; supports frame size of up to 9220 bytes

Ports
24 RJ-45 autosensing 10/100/1000 ports (IEEE 802.3 Type 10BASE-T, IEEE 802.3u Type 100BASE-TX, IEEE 802.3ab Type 1000BASE-T);Duplex: 10BASE-T/100BASE-TX: half or full
1000BASE-T: full only
2 SFP 100/1000 Mbps ports
