Data sheet | HP 5120 EI Switch Series

• Remote intelligent mirroring

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)

monitors a cable between two switches and shuts down the ports on both ends if the cable is

broken, which prevents network problems such as loops

• IPv6 management

provides future-proof networking because the switch is capable of being managed whether

the attached network is running IPv4 or IPv6; supports pingv6, tracertv6, Telnetv6, TFTPv6,

DNSv6, syslogv6, FTPv6, SNMPv6, DHCPv6, and RADIUS for IPv6

• Troubleshooting

ingress and egress port monitoring enables network problem-solving; virtual cable tests

provide visibility into cable problems

Connectivity

• Auto-MDIX

automatically adjusts for straight-through or crossover cables on all 10/100/1000 ports

• Flow control

provides back pressure using standard IEEE 802.3x, reducing congestion in heavy

traffic situations

• Jumbo packet support

supports up to 9216-byte frame size to improve the performance of large data transfers

• High-density connectivity

provides up to 48 fixed 10/100/1000BASE-T ports in a Layer 2/Layer 3 switch

• Optional 10GbE ports

deliver, through the use of optional modules, additional 10GbE connections, which are

available for uplinks or high-bandwidth server connections; flexibly support copper, XFP, SFP+,

or CX4 local connections

• IEEE 802.3at Power over Ethernet (PoE+) support

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 operations, administration and maintenance (OAM)

detects data link layer problems that occurred in the "last mile" using the IEEE 802.3ah OAM

standard; monitors the status of the link between two devices

• High-bandwidth CX4 local stacking

achieves 12 Gb/s per connection when using local CX4 stacking, allowing for up to 96 Gb/s

total stacking bandwidth (full duplex) in a resilient stacking configuration

Performance

• Nonblocking architecture

up to 192 Gb/s nonblocking switching fabric provides wirespeed switching with up

to 143 million pps throughput

• Hardware-based wirespeed access control lists (ACLs)

help provide high levels of security and ease of administration without impacting network

performance with a feature-rich TCAM-based ACL implementation

Resiliency and high availability

• 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
