ASIC Based Forwarding and Services! All packet forwarding and advanced
services are executed in hardware on a custom designed ASIC, not on a CPU
! This ASIC is a programmable, high performance packet classifier and forwarding engine optimized for IPv4, IPv6, and MPLS
! Acts as a centralized resource enabling breakthrough support for performance-based, enhanced services on all interfaces
• filter based forwarding, packet filtering, packet sampling, rate limiting, traffic policing, and port mirroring

Physical Interface Cards (PICs)
! Each FPC has 4 PIC slots, any PIC can go into any slot
! Example: an M10 can be configured with OC-48 SONET, Gig-E, Fast-E, DS-3, and OC-12 SONET
! PIC choices include: Fast-E, Gig-E, T1, DS-3, OC3 (SONET & ATM) , OC12 (SONET & ATM), OC-48 SONET, OC-192 SONET, 10 Gig-E
Mix and Match PICs enable maximum configuration flexibility

Design and Operations Simplicity
Fewer variables and a simpler process mean less time is spent planning, provisioning, and deploying your networks
" CLI enhancements (access controls, command line completion, context sensitive help, rich set of show commands, ect.)
" Industry-standard management protocols (XML, SYSlog, and SNMP)" User-friendly configuration syntax: hierarchical (easy to read), editor
supports local scoping, and comments/inactive command support
