Техническая Спецификация для HP 5500-24G SI JD369A

3

• 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

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 and RSTP: provide

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

• Intelligent Resilient Framework (IRF): creates

virtual resilient switching fabrics, where two or more
switches perform as a single Layer 2 switch, 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, Equal-Cost Multipath
(ECMP), or VRRP

Layer 2 switching

• 16K MAC address table: provides access to

many Layer 2 devices

• VLAN support and tagging: support IEEE

802.1Q, with 4094 simultaneous VLAN IDs

• GARP VLAN Registration Protocol (GVRP):

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

• 10 GbE port aggregation: allows grouping of

ports to increase overall data throughput to a remote
device

• IGMP and MLD 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; supports client; DHCP Relay enables
DHCP operation across subnets

• Loopback interface address: defines an

address in RIP 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

Layer 3 routing

• IPv4 routing protocols: support static routes and

RIP

• IPv6 routing protocols: provide routing of IPv6

at wire speed; support static routes and RIPng

Security

• Access control lists (ACLs): provide IP Layer 2 to

Layer 4 traffic filtering; support global ACL, VLAN
ACL, port ACL, and IPv6 ACL

• IEEE 802.1X: industry-standard method of user

authentication using an IEEE 802.1X supplicant on
the client in conjunction with a RADIUS server

• MAC-based authentication: authenticates the

client with the RADIUS server based on the client's
MAC address
