  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
