QuickSpecs
Overview
Distributed architecture with separation of data and control planes
delivers enhanced fault tolerance and facilitates continuous operation and zero service disruption during planned or unplanned
control-plane events
Advanced Comware modular operating system
brings modularity, enhanced serviceability, stability and independent process monitoring through modern Comware v7
Operating System
In-Service Software Upgrade (ISSU)
provides an upgrade of the entire chassis, or an individual task or process, with zero packet loss
Resiliency and high availability
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
Fully redundant and hot swappable components
providing full hardware redundancy for each component including power supplies, fan trays, supervisor modules and fabric
modules to enable the highest level of availability
Rapid Ring Protection Protocol (RRPP)
provides fast recovery for ring Ethernet-based topology
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
allows limitation of broadcast traffic rate to cut down on unwanted network broadcast traffic
Advanced classifier-based QoS
classifies traffic using multiple match criteria based on Layer 2, 3, and 4 information; applies QoS policies such as setting priority
level and rate limit to selected traffic on a per-port or per-VLAN basis
