With support for up to two port adapters, the VIP supports the following:
●
High port density - Provides a high level of network consolidation; reduces overall inventory, logistics, and maintenance costs.
●
Mixed media - Allows users to obtain better utilization of the slots available in the Cisco 7500. Mixed-media boards (for example, Fast
Ethernet and serial) enable users to tailor the VIPs to specific media and density requirements.
●
Packet memory - Each VIP ships with onboard packet memory, augmenting the total available system memory. This is particularly useful for
applications where a large amount of buffering is required, such as in the presence of bursty traffic conditions, long round-trip propagation
delays, or where there might be many high-bandwidth media vying for access to a smaller number of slower media.
●
Offload processing - By operating a subset of the Cisco IOS Software, a VIP in a Cisco 7500 can offload some of the interface-specific
functions that run in the central processor. This feature increases overall system performance.
●
Distributed switching - Routing information is distributed from the RSP in the Cisco 7500 to one or more interfaces, enabling the VIP to
make its own multilayer switching decisions. This feature enables an architecture that can gracefully scale to meet increasingly higher levels
of system performance.
