HPE 2920-48G-POE+ Managed Switch L3

Product Description

Traffic prioritization (IEEE 802.1p) Traffic prioritization (IEEE 802.1p) allows real-time traffic classification into eight priority levels mapped to eight queues. Layer 4 prioritization Layer 4 prioritization enables prioritization based on TCP/UDP port numbers. Class of Service (Co S) Class of Service (Co S) sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (To S), Layer 3 protocol, TCP/UDP port number, source port, and Diff Serv. Rate limiting Rate limiting sets per-port ingress enforced maximums & per-port, per-queue minimums. Large buffers Large buffers provide graceful congestion management. Auto-MDIX Auto-MDIX automatically adjusts for straight-through or crossover cables on all 10/100 & 10/100/1000 ports. IEEE 802.3at Power over Ethernet (Po E+) IEEE 802.3at Power over Ethernet (Po E+) provides up to 30 W per port that allows support of the Po E+-capable devices such as IP phones, wireless access points, and security cameras, as well as any IEEE 802.3af-compliant end device. HP Pro Vision ASIC architecture Designed with the HP Pro Vision ASIC, providing very low latency, increased packet buffering, and adaptive power consumption. IP multicast snooping & data-driven IGMP IP multicast snooping & data-driven IGMP automatically prevent flooding of IP multicast traffic. LLDP-MED (Media Endpoint Discovery) LLDP-MED (Media Endpoint Discovery) is a standard extension of LLDP that stores values for parameters such as Qo S & VLAN to automatically configure network devices such as IP phones. IEEE 802.1AB Link Layer Discovery Protocol (LLDP) IEEE 802.1AB Link Layer Discovery Protocol (LLDP) is an automated device discovery protocol that provides easy mapping of network management applications. IEEE 802.1s multiple spanning tree IEEE 802.1s multiple spanning tree provides high link availability in multiple VLAN environments by allowing multiple spanning trees;provides legacy support for IEEE 802.1d & IEEE 802.1w. IEEE 802.3ad Link Aggregation Control Protocol (LACP) & HP port trunking IEEE 802.3ad Link Aggregation Control Protocol (LACP) & HP port trunking support up to 60 static, dynamic or distributed trunks active across a stack, with each trunk having up to eight links (ports) per static trunk;trunking across stack members is supported. Ring & chain stacking topology Ring & chain stacking topology allows failure of a link or switch in the ring of stacked switches, while the remaining connected switches continue operation. SNMPv 1, v 2, and v 3 SNMPv 1, v 2, and v 3 provide complete support of SNMP;provide full support of industry-standard Management Information Base (MIB) plus private extensions;SNMPv 3 supports increased security using encryption. Out-of-band Ethernet management port Out-of-band Ethernet management port enables management over a separate physical management network, keeping management traffic segmented from network data traffic. Dual flash images Dual flash images provides independent primary & secondary operating system files for backup while upgrading. Friendly port names Friendly port names allow assignment of descriptive names to ports. Find-fix-inform Find-fix-inform finds & fixes common network problems automatically, then informs administrator. Multiple configuration files Multiple configuration files allow multiple configuration files to be stored to a flash image. Main Specifications
