The microcode boot image in the PROM initializes the VIP4 and then assists downloading the VIP4

microcode image. All interfaces of the same type (VIP4, and so on) will load the same microcode image,

either from the microcode image bundled with the Cisco IOS or from an image stored in system Flash

memory. Although multiple microcode versions for a specific interface type can be stored concurrently

in Flash memory, only one image can load at startup.

The show controllers cbus command displays the currently loaded and running microcode version for

each interface processor and VIP4. The show startup-config EXEC command shows the current system

instructions for loading microcode at startup.

Software and interface processor microcode images are carefully optimized and bundled to work

together. Overriding the bundle can result in system incompatibilities. We recommend that you use the

microcode included in the software bundle. For a complete description of microcode and downloading

procedures, refer to the

ROM Monitor Overview

The VIP4 read-only memory (ROM) monitor, known as Rommon, is firmware. It runs a brief set of

system diagnostics, initializes the VIP4 hardware, and downloads a copy of the Cisco IOS image.The

ROM monitor loads the Cisco IOS image from Flash memory or from a TFTP server. While multiple

Cisco IOS images can be stored in RSP Flash memory, just one can be loaded at system startup.

The VIP4 ROM monitor functions similarly to the boot loader image on the RSP, which runs a copy of

the Cisco IOS image. The boot loader image allows the router to access the Cisco IOS image when

powering up or initializing the system.
