– Dynamic hardware forwarding-table allocations for ease of IPv4-to-IPv6 migration
– Scalable routing (IPv4, IPv6, and multicast) tables, Layer 2 tables, and access-control-list (ACL) and quality-of-service (QoS) entries to make use of 8 queues per port and comprehensive security policies per port
• Infrastructure services:
– Cisco IOS XE Software, the modular open application platform for virtualized borderless services
– Maximum resiliency with redundant components, Nonstop Forwarding/Stateful Switchover (NSF/SSO), and In-Service Software Upgrade (ISSU) support
– Network virtualization through Multi-Virtual Route Forwarding (VRF) technology for Layer 3 segmentation
– Automation through Embedded Event Manager (EEM), Cisco Smart Call Home, AutoQoS, and Auto SmartPorts for fast provisioning, diagnosis, and reporting
• Borderless network services:
– Optimized application performance through deep visibility with Flexible NetFlow supporting rich Layer 2/3/4 information (MAC, VLAN, TCP Flags) and synthetic traffic monitoring with IP service-level agreement (SLA)
– Medianet capabilities to simplify video quality of service, monitoring, and security. In addition, multicast features such as Protocol Independent Multicast (PIM) and Source-Specific Multicast (SSM) that provide enterprise customers the additional scalability to support multimedia applications
– Energy-efficient design with Cisco EnergyWise(tm) technology
• Investment protection and reduced total cost of ownership (TCO):
– Full backward compatibility with 6 G, 24 G, and 48 Gbps slot line cards with no performance degradation
