Description: HPE 5120-48G-PoE+ EI Switch with 2 Interface Slots - Switch - managed - 48 x 10/100/1000 (PoE) + 4 x shared SFP - rack-mountable - PoE - remarketed
Mfr Part #: JG237AR#ABA
The HP 5120 EI switch series is Gigabit Ethernet switch that supports static layer 3 routing, diversified services, and IPv6 forwarding, as well as provide up to four 10-Gigabit Ethernet (10 GbE) extended interfaces. Unique Intelligent Resilient Framework (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. This switch provides Gigabit Ethernet access and can be used at the edge of a network or to connect server clusters in data centers. High scalability provides investment protection with two expansion slots, each of which can support two-port 10 GbE expansion modules. High availability, simplified management, and comprehensive security control policies are among the key features that distinguish this series.
- High scalability for investment protection
- Support for multiple services
- Comprehensive security control policies
- Diversified Quality of Service (QoS) policies
- Excellent manageability
- Broadcast control
It allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic.
- Advanced classifier-based QoS
It 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 port, VLAN, or whole switch.
- Powerful QoS feature
It supports the following congestion actions: strict priority (SP) queuing, weighted round robin (WRR), and SP+WRR.
- Manager and operator privilege levels
It enable read-only (operator) and read-write (manager) access on CLI and Web browser management interfaces.
- Command authorization
It leverages HWTACACS to link a custom list of CLI commands to an individual network administrator's login; also provides an audit trail.
- Secure Web GUI
It provides a secure, easy-to-use graphical interface for configuring the module via HTTPS.
- Complete session logging
It provides detailed information for problem identification and resolution.
- SNMPv1, v2c, and v3
It facilitate centralized discovery, monitoring, and secure management of networking devices.
- Remote monitoring (RMON)
It uses standard SNMP to monitor essential network functions; supports events, alarm, history, and statistics group plus a private alarm extension group.
- IEEE 802.1AB Link Layer Discovery Protocol (LLDP)
Automated device discovery protocol provides easy mapping by network management applications.
- Management VLAN
It segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and SNMP.
- Remote intelligent mirroring
It mirrors ingress/egress ACL-selected traffic from a switch port or VLAN to a local or remote switch port anywhere on the network.
- Device Link Detection Protocol (DLDP)
It monitors cable between two switches and shuts down the ports on both ends if the cable is broken, this prevents network problems such as loops.
It ingress and egress port monitoring enable network problem solving; virtual cable tests provide visibility into cable problems.
- Flow control
Using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations.
- IEEE 802.3at Power over Ethernet (PoE+) support
It simplifies deployment and dramatically reduces installation costs by helping to eliminate the time and cost involved in supplying local power at each access point location.
- Ethernet OAM
It provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network convergence times.
- High-bandwidth CX4 local stacking
When locally stacked using CX4 local stacking, achieves 12 Gbps per connection, allowing for up to 96 Gbps total stacking bandwidth (full duplex) in a resilient stacking configuration.
- Separate data and control paths
It keeps control separated from services and keeps service processing isolated; increases security and performance.
- Rapid Ring Protection Protocol (RRPP)
Connects multiple switches in a high-performance ring using standard Ethernet technology; traffic can be rerouted around the ring in less than 50 ms, reducing the impact on traffic and applications.
- Intelligent Resilient Framework (IRF)
It 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.
