HP 5500-24G-SFP EI JG249AC Hoja De Datos

3

• Optional 10 GbE ports: through the use of

optional modules, additional 10 GbE connections
are available for uplinks or high-bandwidth server
connections; flexibly supports XFP, SFP+, or CX4
local connections

• High-density port connectivity: provides up to

48 fixed 10/100/1000BASE-T or 24 SFP
100/1000BASE-X ports in a Layer 2/Layer 3
stackable switch supporting unique IRF stacking

• 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 OAM: provides a Layer 2 link

performance and fault detection monitoring tool,
which reduces failover and network convergence
times

• High-bandwidth CX4 and SFP+ local

stacking: provide 10 Gbps SPF+ or 12 Gbps CX4
local stacking cables; achieve a resilient stacking
configuration

Performance

• Nonblocking architecture: up to 192 Gbps

nonblocking switching fabric provides wire-speed
switching with up to 143 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: keeps

control separated 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

• Virtual Router Redundancy Protocol (VRRP)

and VRRP-Enhanced (VRRPE): allows a group
of routers to dynamically back each other up to
create highly available routed environments

• 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

• IP Fast Reroute (FRR): forms backup paths and

allows 50 ms switchover in case of a main path fault

Layer 2 switching

• 32K MAC addresses: provide access to many

Layer 2 devices

• 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

• GARP VLAN Registration Protocol: allows

automatic learning and dynamic assignment of
VLANs

• IEEE 802.1ad QinQ: increases the scalability of

an Ethernet network by providing a hierarchical
structure; connects multiple LANs on a high-speed
campus or metro network

• 10 GbE port aggregation: allows grouping of

ports to increase overall data throughput to a remote
device

• 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

Layer 3 services

• Address Resolution Protocol (ARP):

determines the MAC address of another IP host in
the same subnet

• Dynamic Host Configuration Protocol

(DHCP): simplifies the management of large IP
networks and supports client and server; 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
