(VIP4) Installation and Configuration Guide

Product Numbers: VIP4-50=, VIP4-80=, MEM-VIP4-64M-SD=, MEM-VIP4-128M-SD=, MEM-VIP4-256M-SD=

Introduction

This guide provides instructions for installing, configuring, and maintaining the fourth-generation

Versatile Interface Processor (VIP4). The VIP4 operates with the Cisco 7505, Cisco 7507, Cisco

7507-MX, Cisco 7513, Cisco 7513-MX, and the Cisco 7576 routers with the Route Switch Processor

(RSP1, RSP2, RSP4, RSP4+, or RSP8), and with the Cisco 7000 series routers using the 7000 Series

Route Switch Processor (RSP7000) and 7000 Series Chassis Interface (RSP7000CI). See the “Software

Requirements” section on page 9 for specific compatibility requirements.

The VIP4 supports online insertion and removal (OIR), which allows you to remove and replace a VIP4

without first shutting down the system. Online insertion and removal maximizes router availability by

letting you add or remove VIP4s during system operation. See the “Guidelines for VIP4 Removal and

Installation” section on page 15 for more information on removing and installing the VIP4.

The VIP4 supports LAN and WAN port adapters (PAs), including Fast Ethernet, T1/E1, High-Speed

Serial Interface (HSSI), T3/E3, T3/E3 ATM, multichannel T1/E1, multichannel T3/E3, OC-3 ATM,

Packet over SONET (POS), and OC-12 ATM. For a list of supported port adapters, refer to the “VIP4

and Port Adapter Compatibility” section on page 7.

The VIP4 port adapters do not support OIR, so when removing or inserting a port adapter, the system

must be shut down first. The VIP42 must be removed from its interface processor slot before removing

or installing a port adapter.

For complete descriptions of interface subcommands and the configuration options available for

VIP4-related interfaces, refer to the configuration note for each of the port adapters installed on your

VIP4 and to the appropriate Cisco IOS software configuration publications. (See the “Related

Documentation” section on page 2.)

What is the VIP4?

The VIP4 is the fourth generation of Versatile Interface Processors for use with Cisco 7500 or

Cisco 7000 series routers. The VIP4 installs in any interface processor slot on your router, as noted

below:

•Slots 0, 1, 2, 3, or 4 in the Cisco 7000 router

•Slots 0, 1, or 2 in the Cisco 7010 router

•Slots 0, 1, 2, or 3 of the Cisco 7505 router

•Slots 0, 1, 4, 5, or 6 of the Cisco 7507 router

•Slots 0, 1, 2, 3, 4, or 5, and 8, 9, 10, 11, or 12 of the Cisco 7513 router

•Slots 0, 1, 2, 3, 4, or 5 of Router A, and slots 8, 9, 10, 11, or 12 of Router B in the Cisco 7576 router

For more information on interface processor slots on your router, refer to the Cisco 7500 Series

Installation and Configuration Guide or the appropriate Quick Start Guide for the Cisco 7500 series

routers, or refer to Cisco 7000 Hardware Installation and Maintenance manual for the Cisco 7000 series

routers.

How to Identify the VIP4 Model

There are two different versions of the VIP4: the VIP4-50 and the VIP4-80. Both VIP4 versions support

two single-width port adapters or one dual-width port adapter and identical ECC-protected memory

expansion options. Each VIP4 operates with the Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513,

Cisco 7513-MX, and the Cisco 7576 routers.

VIP4 Port Adapter Overview

The VIP4, a single motherboard, supports up to two single-width port adapters, or one dual-width port

adapter. Figure 1 shows a VIP4 with two installed single-width port adapters. A dual-width port adapter

occupies both port adapter slots (not shown).

Note To ensure proper airflow in the router and compliance with EMI prevention standards, a VIP4 with one

single-width port adapter must have a blank port adapter installed in the empty port adapter slot location.

VIP4 Overview

VIP4 and Port Adapter Compatibility

For more information on the available port adapters supported by the VIP4, refer to the Cisco Product

Catalog online, or contact a Cisco sales representative in your area. For more information on a specific

port adapter, refer to the specific port adapter installation and configuration guide. The port adapters,

including part numbers for ordering, are listed in the Cisco Port Adapter Documentation flyer. This

document is available online at http://www.cisco.com/univercd/cc/td/doc/product/core/12939paf.htm or

in print (DOC-7812939).

Note The VIP4 does not support the PA-GE. However, the VIP4-80 supports the Enhanced Gigabit Ethernet

Interface Processor (GEIP+), an assembly consisting of a VIP4-80 with a permanently attached

dual-width Enhanced Gigabit Ethernet port adapter.

Table 5 identifies the port adapters supported by the VIP4 at the time of this writing, and Table 6

identifies the interface processors and service adapters that are supported by the VIP4.

Note The following table does not address which software release applies to the VIP6-80 port adapters. For

Installation Prerequisites

Traffic Management

•Simple Network Management Protocol (SNMP) agent V1 (RFCs 1155-1157)

•Management Information Base (MIB) II (RFC 1213)

Hardware Requirements

The VIP4 is a single motherboard. It operates with:

•Cisco 7505, Cisco 7507, Cisco 7507-MX, Cisco 7513, Cisco 7513-MX, and the Cisco 7576 routers

with the Route Switch Processor (RSP1, RSP2, RSP4, RSP4+, or RSP8); the RSP should have at

least 64 MB of DRAM.

•Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 Series

Chassis Interface (RSP7000CI), the RSP7000 should have at least 64 MB of DRAM.

•Two single-width port adapters, or one dual-width port adapter, supporting multiple LAN and WAN

port adapter types, including Ethernet, Fast Ethernet, Gigabit Ethernet, serial, channelized serial,

multichannel, HSSI, ATM, and POS.

Note The VIP4 requires at least one port adapter installed in order to be supported. A single-width port adapter

must have a blank port adapter installed in the empty port adapter slot location.

Microcode Overview

The VIP4 microcode (firmware) is an image that provides card-specific software instructions. A

programmable read-only memory (PROM) device on the VIP4 contains a default microcode boot image

that assists the system in finding and loading the microcode image from the Cisco IOS bundle or Flash

memory. The router supports downloadable microcode, which enables you to upgrade microcode

versions by downloading new microcode images, storing them in system Flash memory, and instructing

the system to load its image from Flash memory. You can store multiple images for an interface type and,

with a configuration command, instruct the system to load any one of them or the default microcode

image.
