Description

• Quality of Service (QoS)

  Selectable queue configuration: allows you to increase performance and/or traffic reliability by selecting the number of queues that best meet the requirements of your network applications; switch will map 8 priorities to either 2 or 4 queues.Simplified QoS configuration: Port-based: prioritize traffic by specifying a port and priority level. VLAN based: prioritize traffic by specifying a VLAN and priority level.IEEE 802.1p traffic prioritization: honors and sets IEEE 802.1p priority in the VLAN tag.Type of service: IP precedence: honors IP precedence bits and allows mapping to a priority queue. Differentiated Services Code Point values: honors Differentiated Services Code Point (DSCP) bits and allows mapping to a priority queue.Flow control: helps ensure reliable communications during full-duplex operation.

• Management

  Choice of management interfaces: Web graphical user interface (GUI): easy-to-use graphical interface allows configuration of the switch from any Web browser. Command-line interface (CLI): robust command-line interface provides advanced configuration and diagnostics. Simple Network Management Protocol (SNMPv2c/SNMPv3): allows switch to be managed with a variety of third-party network management applications.Integration with HP PCM: enables discovery, mapping, logging, and configuration via HP PCM, which is available as a free download from the Web.Virtual stacking: single IP address manages up to 16 switches.Port mirroring: allows traffic to be mirrored on any port or a network analyzer to assist with diagnostics or detecting network attacks.Multiple configuration files: configuration file management tools allow up to three configuration files to be managed and stored on the switch.

• Connectivity

  Auto-MDIX: automatically adjusts for straight-through or crossover cables on all ports.Small Form-Factor Pluggable (SFP) slots: dual-personality ports allow for either copper or fiber connectivity such as Gigabit-SX, -LX, -LH, and -BX or 100-FX and -BX.IEEE 802.3af Power over Ethernet: provides up to 15.4 W per port to IEEE 802.3af-compliant PoE-powered devices such as IP phones, wireless access points, and security cameras (see product specifications for total PoE power available); supports some prestandard PoE devices (see product FAQs for more details).RJ-45 serial console port: front of unit location provides easy access to the switch CLI.

• Performance

  Switch on a chip: provides highly integrated, high-performance switch design with a non-blocking architecture.Jumbo packet support: supports up to 9216-byte frame size to improve performance of large data transfers (2520G switch).
