Software Packaging on the Router

Software Package Modes

The router can be booted using any of the following:

  • Consolidated—A single software image containing a full collection of software packages. This mode provides a simplified installation and can be stored in the bootflash, a TFTP server, or a network server.

  • Sub-package—One or more sub-images that are extracted from the consolidated image. This mode provides optimized memory usage and requires that you store files in the bootflash directory.

Understanding Software Packages

Table 1. Individual Sub-Packages

Sub-Package

Purpose

RPBase

Route Switch Processor (RSP) operating system

RPControl

Control plane processes between IOS process and the rest of the platform.

RPAccess

Handles security features including Secure Socket Layer (SSL) and Secure Shell (SSH)

RPIOS

Cisco IOS kernel, which is where IOS features are stored and run.

Note 
Each consolidated image has a unique RPIOS package.

FP Pkg

Controls FP daemons.

IO Pkg

Controls input/output driver daemons.

LC Base

Controls basic kernel functions including runtime, initialization scripts, and chassis control daemons.

Sub-Package

Purpose

RPBase

Route Switch Processor (RSP) operating system

RPControl

Control plane processes between IOS process and the rest of the platform.

RPAccess

RPIOS

Cisco IOS kernel, which is where IOS features are stored and run.

Note 
Each consolidated image has a unique RPIOS package.

SIPSPA Base

Controls interface module daemons.

Provisioning Files

Provisioning files manage the boot process when the router is configured to boot in sub-packages. The provisioning file manages the bootup of each individual sub-package. Provisioning files are extracted automatically when individual sub-package files are extracted from a consolidated package. Provisioning files are not necessary for running the router using the complete consolidated package.

File Systems on the Router

Table 3. File Systems

File System

Description

bootflash:

The boot flash memory file system on the active RSP.

cns:

stby-harddisk:

The hard disk file system on the standby RSP.

stby-usb0:

The Universal Serial Bus (USB) flash drive file systems on the standby RSP.

Note 

stby-usb1: is an internal port.

system:

The system memory file system, which includes the running configuration.

tar:

The archive file system.

tmpsys:

The temporary system files file system.

usb0:

The Universal Serial Bus (USB) flash drive file systems on the active RSP.

Note 
usb1: is an internal port.

If you see a file system not listed in the above table, enter the ? help option or see the copy command reference for additional information on that file system.

Autogenerated Files and Directories


Caution

Any autogenerated file in the bootflash: directory should not be deleted, renamed, moved, or altered in any way unless directed by customer support; altering these files can have unpredictable consequences for system performance.

Table 6. Autogenerated Files

File or Directory

Description

crashinfo files

A crashinfo file may appear in the bootflash: file system.

Crashinfo files are useful for tuning and troubleshooting, but are not related to router operations: you can erase them without impacting the router’s performance.

core files

The bootflash/core directory is the storage area for .core files.

Warning 
Do not erase or move the core directory.

lost+found directory

This directory is created on bootup if a system check is performed. Its appearance is completely normal and does not indicate any issues with the router.

tracelogs files

The storage area for trace files is bootflash/tracelogs.

Trace files are useful for troubleshooting; you can access trace files using diagnostic mode to gather information related to the IOS failure.

Warning 
Do not erase or move the tracelog directory.
