|The HP 5120 EI Switch Series delivers flexibility, scalability and low TCO with a robust feature set supporting stacking, static layer 3 routing, PoE+, ACLs and IPv6. HP 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. The HP 5120 EI Switch Series can be managed with the HP Intelligent Management Center (IMC) for a single view of your network.|
- Scalable and Secure Access Layer Switches.
The HP 5120 EI Switch Series supports stacking, static layer 3 routing, PoE+, ACLs and IPv6. HP Intelligent Resilient Framework (IRF) technology creates a virtual fabric which increases network resilience, performance, and availability while reducing operational complexity. HP 4 chassis IRF for simpler, flatter, more agile networks and flexible deployment with longer-distance stacking between closets up to 70 km distance. Modular 10GbE uplinks (CX4, SFP+ and 10GBASE-T), stacking and power supplies allow for future upgradability. External redundant power supply for increased reliability. Limited Lifetime Warranty 2.0 with 3 years 24x7 phone support and no software licensing required.
- Powerful Quality of Service (QoS).
The HP 5120 EI 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 port, VLAN, or whole switch. Traffic prioritization with supported congestion actions include: strict priority (SP) queuing, weighted round robin (WRR), and SP+WRR and traffic policing with Committed Access Rate (CAR) and line rate.
- Comprehensive Security Control.
The HP 5120 EI Switch Series supports flexible authentication methods including 802.1X, MAC, and Web Authentication for greater security and policy-driven application authentication. Access control lists (ACLs) provide IP Layer 2 to Layer 4 traffic filtering; supports global ACL, VLAN ACL, port ACL, and IPv6 ACL. Source-port filtering, RADIUS/TACACS+, SSL, Port Security, and MAC address lockout deliver enhanced security.
- Single View of the Network.
The HP 5120 EI Switch Series can be seamlessly managed with HP Intelligent Management Center (IMC) to provide end-to-end network transparency with consistent network experience through comprehensive configuration, compliance and policy management. RMON and sFlow provide advanced monitoring and reporting capabilities for statistics, history, alarms and events.
- Separate data and control paths: separates control from services and keeps service processing isolated; increases security and performance. External redundant power supply: provides high reliability. Smart link: allows 50 ms failover between links. Spanning Tree/MSTP, RSTP: provides redundant links while preventing network loops. 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.
- 16K MAC address table: provides access to many Layer 2 devices. VLAN support and tagging: supports IEEE 802.1Q with 4,094 simultaneous VLAN IDs. GARP VLAN Registration Protocol: allows automatic learning and dynamic assignment of VLANs. IEEE 802.1ad QinQ and selective QinQ: increase the scalability of an Ethernet network by providing a hierarchical structure; connect multiple LANs on a high-speed campus or metro network. 10GbE port aggregation: allows grouping of ports to increase overall data throughput to a remote device.
- 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; proxy ARP allows normal ARP operation between subnets or when subnets are separated by a Layer 2 network. 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 that can always be reachable, improving diagnostic capability. User Datagram Protocol (UDP) helper function: allows UDP broadcasts to be directed across router interfaces to specific IP unicast or subnet broadcast addresses and prevents server spoofing for UDP services such as DHCP. Route maps: provide more control during route redistribution; allow filtering and altering of route metrics.
