HP 2910-48G al Switch J9147A
- Fixed Port Layer-3 Managed Ethernet Switch.
- 44 autosensing 10/100/1000 port, 4 dual-personality ports SFP.
Features
Quality of Service (QoS)
- Traffic prioritization (IEEE 802.1p): allows real-time traffic classification into eight priority levels mapped to eight queues
- Layer 4 prioritization: enables prioritization based on TCP/UDP port numbers
- Class of Service (CoS): sets the IEEE 802.1p priority tag based on IP address, IP Type of Service (ToS), Layer 3 protocol, TCP/UDP port number, source port, and DiffServ
- Rate limiting: per-port ingress enforced maximums
Connectivity
- 10 Gbps Ethernet connectivity: up to four optional and flexible 10-Gigabit ports (CX4 and/or SFP+), with optional interconnect kit for short-distance connectivity
- IPv6: IPv6 host: allows the switches to be managed and deployed at the edge of IPv6 networks . Dual stack (IPv4/IPv6): provides transition mechanism from IPv4 to IPv6; supports connectivity for both protocols. MLD snooping: forwards IPv6 multicast traffic to the appropriate interface; prevents IPv6 multicast traffic from flooding the network.
- IEEE 802.3af Power over Ethernet (PoE): 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
- IEEE 802.3at Power Over Ethernet Plus: provides up to 30 W per port to IEEE 802.3 for PoE/PoE+ powered devices such as video IP phones, IEEE 802.11n wireless access points, and advanced pan/zoom/tilt security cameras
- Pre-standard PoE support: detects and provides power to pre-standard PoE devices
Performance
- High-performance architecture: 128 Gbps switching fabric with up to 95 Mpps (24-port switches) and 176 Gbps switching fabric with up to 131 Mpps (48-port switches)
- Selectable queue configurations: allow you to increase performance by selecting the number of queues and associated memory buffering that best meet the requirements of your network applications
Resiliency and high availability
- 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 and IEEE 802.1w
- IEEE 802.3ad Link Aggregation Protocol (LACP) and HP port trunking: support up to 24 trunks, each with up to 8 links (ports) per trunk.
