Chapter 3 Installation Overview

Where to Go Next

The Cisco IOS XE CLI can be accessed either through the virtual console or on a serial port console. The console can be selected from GRUB mode during the first-time installation, or it can be changed using the Cisco IOS XE platform console command after the router boots. For more information, see the “Booting the Cisco CSR 1000V and Accessing the Console” section on page 8-1.

Note Some hypervisors may not support serial console access. Verify support using your hypervisor documentation.

ROMMON and the Cisco CSR 1000V

The Cisco CSR 1000V does not include a ROMMON image similar to what is included in many Cisco hardware-based routers. During the initial bootloader process, the installation script creates a clean version of the Cisco CSR 1000V software image known as the Golden Image and places it in a non-accessible partition. This clean version can be used if the software image is not working properly or is not bootable.

Note that although the Cisco CSR 1000V does not include ROMMON, the platform does include a GNU GRand Unified Bootloader (GRUB)-based bootloader. The GRUB function on the Cisco CSR 1000V provides more limited functionality compared to the ROMMON available on other Cisco platforms.

Note that although ROMMON is not present on the Cisco CSR 1000V, some Cisco IOS XE commands such as show version may show references to ROMMON in the command output.

Note After the Cisco CSR 1000V completes the first-time installation, you can configure the router to automatically enter GRUB mode when the router is booted. For more information, see the “Managing Cisco CSR 1000V Licenses” section on page 13-1.
