Versatile Interface Processor Functions
The following sections describe the Versatile Interface Processor (VIP) and discuss VIP-specific
features and functions, such as installing and removing the VIP, installing and removing port
adapters, using and configuring common VIP interface functions.
What is the VIP?
The VIP is a new interface processor for use with the Cisco 7000 series and Cisco 7500 series
routers, and it installs in the interface processor slots in your Cisco 7000 series or 7500 series router.
The VIP uses a single motherboard with up to two port adapters. The VIP port adapters provide the
individual LAN, WAN, or LAN/WAN interface ports. The VIP can be removed from a chassis while
power is on and the system is operating.
Caution The VIP supports online insertion and removal (OIR), which allows you to remove and
replace a VIP without first shutting down the system. Online insertion and removal maximizes router
availability by letting you add or remove VIPs during system operation; however, the system may
indicate a hardware failure if you fail to follow proper procedures. To help avoid problems with the
installation, review the functional description in the section “Online Insertion and Removal—An
Overview” on page 13, and follow the VIP installation steps carefully.
