Podpora IEEE 802.1p (QoS) na 1G portech
DMS-107 je multigigabit ethernetový přepínač, který poskytuje ultrarychlá připojení k páteři vaší sítě nebo k síťovému úložišti (NAS). Během pár minut snadno propojíte více počítačů a můžete začít sdílet připojení k internetu, soubory, hudbu a video v rámci vaší malé kanceláře nebo domácí sítě.
Připraveno pro Wi-Fi 6
Přináší multigigabitové porty pro maximální propustnost a výkon – ideální pro používání Wi-Fi 6 zařízení, špičkových herních počítačů a pracovních stanic. Vícegigabitové porty eliminují potenciální úzká hrdla s Wi-Fi 6 přístupovými body, což umožní síti plně využít efektivitu a rychlost poskytované technologií Wi-Fi 6.
Automatická optimalizace provozu
S přenosovými rychlostmi 2,5 Gb/s na uplinkových portech můžete rychle přenášet do počítačů soubory mezi připojenými servery a síťovým úložištěm (NAS). Podpora IEEE 802.1p Quality of Service (QoS) na gigabitových portech automaticky organizuje a upřednostňuje časově citlivá a kritická data (8 úrovní), což umožňuje např. streamování videa bez vyrovnávací paměti, plynulé hlasové a video hovory, apod.
Pohodlí Plug & Play instalace
DMS-107 je zařízení typu plug-and-play, které nevyžaduje žádnou pokročilou technickou konfiguraci. Propojením ethernet kabely okamžitě vytvoříte síť.
Navrženo pro život, postaveno tak, aby to vydželo
Bezventilátorová konstrukce DMS-107 zajišťuje tichý provoz, sníženou spotřebu energie a zvýšenou spolehlivost. Jeho robustní kompaktní kovové pouzdro zajišťuje, že produkt vydrží širší rozsah provozních teplot tím, že pomáhá odvádět teplo a snižuje tak zátěž vnitřních komponent.
Úspora energie
Kompaktní kovové pouzdro a design bez ventilátoru zajišťují tichý provoz a dovolují umístění přepínače prakticky kdekoli. DMS-107 je navržen s ohledem na energetickou ohleduplnost. Přepínače automaticky snižují napájení portů, které jsou neaktivní nebo nejsou připojeny, a podporují standard IEEE 802.3az (Energy-Efficient Ethernet).

Loopback detection Provides protection against loops by transmitting loop protocol packets out of ports on which loop protection has been enabled. It operates independently of STP
Layer 3 routing IPv4 routing Wire-speed routing of IPv4 packets
Up to 32 static routes and up to 16 IP interfaces
IPv6 routing Wire-speed routing of IPv6 packets
Layer 3 interface Configuration of Layer 3 interface on physical port, LAG, VLAN interface, or loopback interface
Classless Interdomain Routing (CIDR) Support for CIDR
Dynamic Host Configuration Protocol (DHCP) relay at Layer 3 Relay of DHCP traffic across IP domains
User Datagram Protocol (UDP) relay Relay of broadcast information across Layer 3 domains for application discovery or relaying of Bootstrap Protocol (BootP)/DHCP packets
Security Secure Sockets Layer (SSL) Encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch
SSH Protocol SSH is a secure replacement for Telnet traffic. Secure Copy (SCP) also uses SSH. SSH v1 and v2 are supported.
IEEE 802.1X (authenticator role) RADIUS authentication, guest VLAN, single/multiple host mode, and single/multiple sessions
STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops)
Secure Core Technology (SCT) Ensures that the switch will receive and process management and protocol traffic no matter how much traffic is received
Secure Sensitive Data (SSD) A mechanism to manage sensitive data (such as passwords, keys, and so on) securely on the switch, populating this data to other devices and a secure auto-configuration. Access to view the sensitive data as plain text or encrypted is provided according to the user-configured access level and the access method of the user
Trustworthy systems Trustworthy systems provide a highly secure foundation for Cisco products
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 DoS attack prevention
Multiple user privilege levels in CLI Level 1, 7, and 15 privilege levels
ACLs Support for up to 512 rules
Drop or rate limit based on source and destination MAC, VLAN ID, 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
Quality of service 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
