Plug-and-play stacking configuration/management Active/standby for resilient stack control Auto-numbering
Hot swap of units in stack
Ring and chain stacking options, auto stacking port speed, flexible stacking port options
High-speed stack interconnects Cost-effective high-speed 10 Gigabit Ethernet fiber interfaces

Web-based authentication Web-based authentication provides network admission control through a web browser to any host devices and operating systems
STP Bridge Protocol Data Unit (BPDU) Guard A security mechanism to protect the network from invalid configurations. A port enabled for BPDU Guard is shut down if a BPDU message is received on that port. This avoids accidental topology loops

TP-Link VIGI C440-W (4mm)
Kopulová Wi-Fi síťová kamera VIGI 4 MPx (4mm)
4 MPx s rozlišením UHD: Kamera VIGI C440 má rozlišení 4 MPx – více než dost pixelů na to, aby zachytila některé diskrétnější detaily.
Nepřetržité barevné snímání: Spolehněte se na 24hodinové snímání barevných detailů i v černočerné tmě díky vysoce citlivému snímači a LED bodovým světlům.
Bezdrátové připojení: Snadné a rychlé nasazení na místa pokrytá Wi-Fi signálem.
Chytrá detekce (detekce pohybu, narušení prostoru, překročení linie, neoprávněná manipulace s kamerou): Přijímejte oznámení a kontrolujte videokanály, když někdo překročí hranici, vstoupí do nastavené oblasti nebo překáží kameře.
Chytré kódování H.265+: Kamery přenášejí komprimovaný křišťálově čistý obraz, aniž by využívaly další šířku pásma, a šetří tak místo na disku, snižují zatížení sítě a náklady na monitorování – to vše bez snížení kvality obrazu.
Vzdálené sledování: Spravujte své zabezpečení přímo z dlaně pomocí aplikace VIGI.

Run-time defenses (Executable Space Protection [X-Space], Address Space Layout Randomization [ASLR], Built-In Object Size Checking [BOSC])
Port security Ability to lock source MAC addresses to ports and limit the number of learned MAC addresses
RADIUS Supports RADIUS authentication for management access. Switch functions as a client.
Storm control Broadcast, multicast, and unknown unicast
DoS prevention Denial-of-Service (DoS) attack prevention
Multiple user privilege levels in CLI Level 1, 7, and 15 privilege levels
Access Control Lists (ACLs) Support for up to 512 rules
Drop or rate limit based on source and destination MAC, VLAN ID or IPv4 or IPv6 address, IPv6 flow label, protocol, port, Differentiated Services Code Point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag; ACL can be applied on both ingress and egress sides
Time-based ACLs supported
QoS Priority levels 8 hardware queues
Scheduling Strict priority and Weighted Round-Robin (WRR) queue assignment based on DSCP and class of service (802.1p/CoS)
Class of service Port based; 802.1p VLAN priority based; IPv4/v6 IP precedence/Type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and re-marking ACLs, trusted QoS
Rate limiting Ingress policer; egress shaping and rate control; per VLAN, per port, and flow based
Congestion avoidance A TCP congestion avoidance algorithm is required to reduce and prevent global TCP loss synchronization
