QuickSpecs
Overview
Intelligent Resilient Framework (IRF)
creates virtual resilient switching fabrics, where two or more switches perform as a single L2 switch and L3 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; can eliminate the need for complex protocols like Spanning Tree
Protocol, Equal-Cost Multipath (ECMP), or VRRP, thereby simplifying network operation
Ultrafast protocol convergence
enables link connectivity monitoring and reduces network convergence time for RIP, OSPF, BGP, IS-IS, VRRP, MPLS, and IRF
Device Link Detection Protocol (DLDP)
monitors link connectivity and shuts down ports at both ends if unidirectional traffic is detected, preventing loops in STP-based
networks
Complete set of routing protocols (Layer 3 IPv4 and IPv6)
support virtually all existing routing protocols (RIP, OSPF, IS-IS, and BGP) for both Layer 3 IPv4 and Layer 3 IPv6; complete
support of PIM-DM, PIM-SM, PIM-SSM, and MSDP
Hot patching
the 12500 switch series supports hot patching, allowing in-service patching for some isolated software problems
Non Stop Forwarding/Graceful Restart (NSF/GR)
using standardized-based IETF protocols, the 12500 switch series provides nonstop forwarding (switching/routing) for Layer 3
routing protocols (control plane – OSPF, BGP, and MPLS), providing hitless failover
Ultrareliable architecture
combining hardware redundancy at every layer (power supplies, fans, supervisory modules, etc.) and a multilayered software
approach based on the Resilient Virtual Switching Fabric concept (using the IRF technology), the 12500 switch series is able to
provide the highest level of availability; by following design guidelines from HP, customers can build data centers providing an
end-to-end availability reaching five 9s
Rapid Ring Protection Protocol (RRPP)
provides fast recovery for ring Ethernet-based topology
Performance
13.32 Tb/s (12518 switch), 6.12 Tb/s (12508 switch), and 3.24 Tb/s (12504 switch) fully nonblocking CLOS architecture
includes a high-performance switch design with a nonblocking architecture
High-performance bandwidth
with up to 13.32 Tb/s capacity, providing nonblocking throughput for 288 10GbE ports at Layer 2 and Layer 3 IPv4, Layer 3 IPv6,
and MPLS (12518 switch), 128 10GbE ports (12508 switch), or 64 10GbE ports (12504 switch)
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
High-performance processor system
the supervisory module uses three different processors to isolate key tasks: control plane (STP, OSPF, BGP, MPLS, etc.), fast
recovery protocols (RRPP, BFD, etc.), and chassis management (temperature, power, etc.)
Quality of Service (QoS)
Virtual Output Queue (VOQ)
prevents head-of-line (HOL) blocking per port at peak time and distributes it over a period of time, increasing switch
performance
IEEE 802.1p prioritization
delivers data to devices based on the priority and type of traffic
Layer 4 prioritization
enables prioritization based on TCP/UDP port numbers
Broadcast control
