Cisco Second-Generation Versatile Interface Processor - ...

The VIP2-40 provides the same basic features as the VIP2-15 and offers support for Distributed Switching and Distributed Services. Powered by the same processor as the VIP2-15, it provides larger program memory (DRAM) to accommodate Layer 3 route information from the RSP for autonomous switching decisions, and larger packet memory (SRAM) capacity necessary for Distributed IP Services. In addition, the VIP2-40 runs a subset of Cisco IOS software to provide support for enhanced network services such as distributed queuing and software-based encryption and compression. This model also supports the specialized hardware assist engines for increased compression and encryption bandwidth applications.
