Versatile Interface Processor (VIP)

The VIP card (VIP, VIP-2, or VIP-2-50) uses a single motherboard with one or two replaceable port adapters (PA) or service adapters (SA).

Any combination of two PA or SA cards can be installed in a VIP-2 card or VIP-2-50 card.

The first-generation VIP card supports the following combinations of Ethernet (10BaseT), Fast Ethernet (100BaseTX), Fast Serial, and Token Ring ports:

One Fast Ethernet PA

Two Fast Ethernet PAs

One Fast Ethernet PA and one Ethernet PA

One Ethernet PA and one Fast Serial PA

One Token Ring PA and one Fast Serial PA

VIP4

VIP4 is the fourth generation Versatile Interface Processor for 7500 series routers.

VIP4 is based on a 250MHz R7000 MIPS microprecessor and a system controller ASIC.

The primary features of the VIP4 are:

250MHz RM7000 CPU.

Support for all legacy port adapters.

Distributed and Non-distributed versions.

Large memory configuration.

VIP6-80

The Cisco Versatile Interface Processor 6-80 Services Accelerator (VIP6-80) provides up to a 40 percent improvement over the Cisco VIP4 and a more than 100 percent improvement over the Cisco VIP2-50 when distributed features and quality-of-service (QoS) services are enabled on an interface. As such, the Cisco VIP6-80 is ideal for enterprise and service provider customers who require high-performance, high-speed interfaces and applications.

The Cisco VIP6-80 Services Accelerator is ideal for networks that require the highest-speed interfaces such as OC-12 or OC-3 ATM or channelized STM-1 combined with the application of Layer 3-7 services to these interfaces.

Performance on these interfaces is significantly enhanced when certain features and QoS services are enabled. Examples of some of these distributed features and QoS services include the following:

Distributed Committed Access Rate (dCAR)

Distributed Weighted Fair Queuing (dWFQ)

Distributed Weighted Random Early Detection (dWRED)

Distributed Traffic Shaping (dTS)

Distributed Network-Based Application Recognition (dNBAR)

Multiprotocol Label Switching (MPLS)

MPLS Virtual Private Networking (VPN)

MPLS VPN + QoS
