HP 5120 SI Series Spezifikation
QuickSpecs
Overview
SNMPv1, v2c, and v3: facilitate centralized discovery, monitoring, and secure management of networking devices
Remote monitoring (RMON): 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: segments traffic to and from management interfaces, including CLI/telnet, a Web browser interface, and
SNMP
Device Link Detection Protocol (DLDP): monitors a cable between two switches and shuts down the ports on both ends if the
cable is broken, this prevents network problems such as loops
Connectivity
Auto-MDIX: automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports
Flow control: using standard IEEE 802.3x, it provides back pressure to reduce congestion in heavy traffic situations
Jumbo packet support: supports up to 10k byte frame size to improve performance of large data transfers
High-density port connectivity: provides up to 48 fixed 10/100/1000BASE-T ports in an entry-level static Layer 3 switch
Ethernet OAM: provides a Layer 2 link performance and fault detection monitoring tool, which reduces failover and network
convergence times
Power over Ethernet Plus (PoE+) support: provides 30 W power for connected devices, 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
IPv6:
IPv6 Host: enables switches to be managed and deployed at the IPv6 network's edge
Dual stack (IPv4 and IPv6 using BIS): allows IPv4 hosts to communicate with IPv6 hosts
IPv6 ACL: for filtering IPv6 network traffic
Performance
Nonblocking architecture: up to 104 Gbps nonblocking switching fabric provides wire-speed switching with up to 77.4 million
pps throughput
Hardware-based wire-speed access control lists (ACLs): feature-rich ACL implementation (TCAM-based) helps ensure high
levels of security and ease of administration without impacting network performance
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
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
