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
• 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
• 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 link-aggregation
control protocol (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
Provides standard sub-100 ms recovery for a ring Ethernet-based topology (Comware v5 only)
• VRRP
Allows groups of two routers to dynamically back each other up to create highly available
routed environments
• Device link detection protocol
Monitors link connectivity and shuts down ports at both ends if unidirectional traffic is
detected, helping prevent loops in STP-based networks
• Hitless patch upgrades
Allows patches and new service features to be installed without restarting the equipment,
increasing network uptime and facilitating easy maintenance
• IEEE 802.3ad 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
• Graceful restart
Supports graceful restart for the open-shortest path first (OSPF), intermediate system to
intermediate system (IS-IS), border gateway protocol (BGP), LDP, and RSVP; the network
remains stable during the active-standby switchover; after the switchover, the device quickly
learns the network routes by communicating with adjacent routers; and forwarding remains
uninterrupted during the switchover to achieve nonstop forwarding
• Ultrafast protocol convergence (sub-second) with standards-based failure detection—
bidirectional forwarding detection
Enables link connectivity monitoring and reduces network convergence time for the routing
information protocol (RIP), OSPF, BGP, IS-IS, VRRP, MPLS, and IRF
• SmartLink
Allows 100 ms failover between links (Comware v5 only)
• Multiple internal power supplies
Provides high reliability; the 10504 switch provides 3+1 redundancy; and the 10508, 10508-V,
and 10512 switches provide 5+1 redundancy
