HP 5120-24G-PoE+ (170W) SI Switch
-
Managed Access Layer Switches
- The HP 5120 SI Switch Series supports stacking, static IP routing, PoE+, ACLs and IPv6 and is designed for the access layer of medium and large enterprises.
- HP Intelligent Resilient Framework (IRF) technology on the 5120 SI Switch Series uses Gigabit Ethernet ports to stack up to four switches creating a virtual fabric which increases network resilience, performance, and availability while reducing operational complexity.
- PoE+ models support up to 370W PoE power for connected devices.

Ā
Advanced Quality of Service (QoS)
- The HP 5120 SI Switch Series supports advanced classifier-based QoS which classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority level and rate limit to selected traffic on a per port basis.
- Traffic prioritization with supported congestion actions include: strict priority (SP) queuing, SDWRR and SP+WRR.
-
Ā
Security Control
- The HP 5120 SI Switch Series supports MAC Authentication for improved security and authentication.
- Hardware-based wire-speed access control lists (ACLs) providing high levels of security and ease of administration without impacting network performance.
- RADIUS/HWTACACS, SSL, Port Security, and 802.1x and MAC-based authentication deliver enhanced security.
-
Ā
Single View of the Network
- The HP 5120 SI Switch Series can be seamlessly managed with the optional HP Intelligent Management Center (IMC) Software to provide end-to-end network transparency with consistent network experience through comprehensive configuration, compliance and policy management.
- RMON provides advanced monitoring and reporting capabilities for statistics, history, alarms and events.

Ā
Resiliency and high availability
- Separate data and control paths: increases security and performance
- Spanning Tree/MSTP, RSTP: provides redundant links while preventing network loops
- IEEE 802.3ad Link Aggregation Control Protocol (LACP): supports up to 26 trunks, each with 8 links per trunk; supports static or dynamic groups
- Smart link: allows 50 ms failover between links
- Intelligent Resilient Framework (IRF): creates virtual resilient switching fabrics, where two or more switches perform as a single Layer 2 switch and Layer 3 router; switches do not have to be co-located and can be part of a disaster-recovery system; servers or switches can be attached using standard LACP for automatic load balancing and high availability; simplifies network operation by eliminating the complexity of Spanning Tree Protocol, Equal-Cost Multipath (ECMP), or VRRP
-
Ā
Layer 2 switching
- 8K MAC address table: provides access to many Layer 2 devices
- VLAN support and tagging: support IEEE 802.1Q with 4,094 simultaneous VLAN IDs
- IP multicast snooping: automatically prevents flooding of IP multicast traffic
- Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) protocol snooping: effectively control and manage the flooding of multicast packets in a Layer 2 network
-
Ā
Layer 3 services
- Address Resolution Protocol (ARP): determines the MAC address of another IP host in the same subnet; supports static ARPs; gratuitous ARP allows detection of duplicate IP addresses
- Dynamic Host Configuration Protocol (DHCP): simplifies the management of large IP networks; supports client; DHCP Relay enables DHCP operation across subnets
- Loopback interface address: defines an address in Routing Information Protocol (RIP) and OSPF that can always be reachable, improving diagnostic capability
