Resiliency and high availability
• Redundant/load-sharing fabrics, management, fan assemblies, and power supplies
Increase total performance and power availability, while providing hitless, stateful failovers
• All hot-swappable modules
Allows replacement of modules without any impact on other modules
• Dual internal power supply
Provides high reliability
• Separate data and control paths
Separates control from services and keeps service processing isolated; and increases security
and performance
• Passive design system
Delivers increased system reliability as the backplane has no active components
• IEEE 802.3ad link-aggregation control protocol (LACP)
Supports up to 128 trunks, each with 8 links per trunk; and provides support for static or
dynamic groups and a user-selectable hashing algorithm
• Intelligent resilient framework (IRF)
Creates virtual resilient switching fabrics, where two or more switches perform as a single
L2 switch and L3 router; switches don't have to be co-located and can be part of a disaster-
recovery system; servers or switches can be attached using the standard LACP for automatic
load balancing and high availability; it can help eliminate the need for complex protocols such
as spanning tree protocol (STP), equal-cost multipath (ECMP), or virtual router redundancy
protocol (VRRP)—simplifying network operations
• IRF capability
Provides single IP address management for a resilient virtual switching fabric of up to four
switches
• Ring resiliency protection protocol (RRPP)
Provides standard sub-100 ms recovery for a ring Ethernet-based topology
• VRRP
Allows groups of two routers to dynamically back each other up to create highly available
routed environments
• Hitless patch upgrades
Allows patches and new service features to be installed without restarting the equipment,
increasing network uptime and facilitating easy maintenance
