Các tính năng của Switch Cisco SG250-08HP-K9-EU   Layer 2 switching Spanning Tree Protocol (STP) Standard 802.1d spanning tree support Fast convergence using 802.1w (Rapid Spanning Tree Protocol [RSTP]), enabled by default Multiple spanning tree instances using 802.1s (MSTP); 8 instances are supported Port grouping/link aggregation Support for IEEE 802.3ad Link Aggregation Control Protocol (LACP) ●  Up to 4 groups
●  Up to 8 ports per group with 16 candidate ports for each (dynamic) 802.3ad LAG
VLAN Support for up to 256 active VLANs simultaneously Port-based and 802.1Q tag-based VLANs Management VLAN Guest VLAN Voice VLAN Voice traffic is automatically assigned to a voice-specific VLAN and treated with appropriate levels of QoS. Auto voice capabilities deliver networkwide zero-touch deployment of voice endpoints and call control devices Generic VLAN Registration Protocol (GVRP)and Generic Attribute Registration Protocol (GARP) Protocols for automatically propagating and configuring VLANs in a bridged domain IGMP (versions 1, 2, and 3) snooping Internet Group Management Protocol (IGMP) limits bandwidth-intensive multicast traffic to only the requesters; supports 4K multicast groups (source-specific multicasting is also supported) IGMP querier Used to support a Layer 2 multicast domain of snooping switches in the absence of a multicast router HOL blocking Head-Of-Line (HOL) blocking 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 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 bootP/DHCP packets Security SSL Secure Sockets Layer (SSL) encrypts all HTTPS traffic, allowing secure access to the browser-based management GUI in the switch Secure Shell (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 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 secure autoconfig. Access to view the sensitive data as plaintext or encrypted is provided according to the user-configured access level and the access method of the user 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 Access Control Lists (ACLs) Support for up to 512 rules Drop or rate limit based on source and destination MAC, VLAN ID or IP address, 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 STP loopback guard Provides additional protection against Layer 2 forwarding loops (STP loops) 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 Giá sản phẩm trên Tiki đã bao gồm thuế theo luật hiện hành.
