* Giới thiệu chung về Switch HP JG237A:

- The HP 5120 EI Switch Series delivers flexibility, scalability, and low total cost of ownership (TCO) with a robust feature set supporting stacking, static layer 3 routing, PoE+, ACLs, and IPv6. HP Intelligent Resilient Fabric (IRF) technology creates a virtual fabric by managing several switches as one logical device, which increases network resilience, performance, and availability while reducing operational complexity.

- The HP 5120 EI Switch Series can be managed with the HP Intelligent Management Center (IMC) for a single view of your network.

- Features

+ Scalable and Secure Access Layer Switches

  • The HP 5120 EI Switch Series supports stacking, static layer 3 routing, PoE+, ACLs, and IPv6. HP Intelligent Resilient Fabric (IRF) technology creates a virtual fabric which increases network resilience, performance, and availability while reducing operational complexity.
  • HP 4-chassis IRF for simpler, flatter, more agile networks, and flexible deployment with longer-distance stacking between closets up to 70 km.
  • Modular 10GbE uplinks (CX4, SFP+ and 10GBASE-T), stacking and power supplies allow for future upgradability.
  • External redundant power supply for increased reliability.
  • Limited Lifetime Warranty 2.0 with 3 years 24x7 phone support and no software licensing required.

+ Powerful Quality of Service (QoS)

  • The HP 5120 EI Switch Series supports advanced, classifier-based QoS which directs traffic using multiple match criteria based on Layer 2, 3, and 4 information. The switches apply QoS policies such as setting priority level and rate limit to selected traffic on a port, VLAN, or whole switch.
  • Traffic prioritization with supported congestion actions include: strict priority (SP) queuing, weighted round robin (WRR), SP+WRR, and traffic policing with Committed Access Rate (CAR) and line rate.

+ Comprehensive Security Control

  • The HP 5120 EI Switch Series supports flexible authentication methods including 802.1X, and MAC and Web for greater policy-driven application security.
  • This series uses access control lists (ACLs) to provide IP Layer 2 to Layer 4 traffic filtering. And it supports global ACL, VLAN ACL, port ACL, and IPv6 ACL.
  • Source-port filtering, RADIUS/TACACS+, SSL, Port Security, and MAC address lockout deliver enhanced security.

+ Single View of the Network

  • The HP 5120 EI Switch Series can be seamlessly managed with HP Intelligent Management Center (IMC) to provide end-to-end network transparency with consistent network experience through comprehensive configuration, compliance and policy management.
  • RMON and sFlow provide advanced monitoring and reporting capabilities for statistics, history, alarms, and events.
