This chapter describes how to update software on the Cisco NCS 520 Series Router.
Generally an upgrade is only necessary in cases where a system message indicates that an upgrade is required or a Cisco technical support representative suggests an upgrade.
The procedures in this chapter describe how to upgrade the firmware on the router.
The table below provides a list of file systems that can be seen on the Cisco NCS 520 Series Router.
|
File System |
Description |
|---|---|
|
bootflash: |
The boot flash memory file system. |
|
cns: |
The Cisco Networking Services file directory. |
|
nvram: |
Router NVRAM. You can copy the startup configuration to NVRAM or from NVRAM. |
|
system: |
The system memory file system, which includes the running configuration. |
|
tmpsys: |
The temporary system files file system. |
If you see a file system not listed in the table above, enter the ? help option or see the copy command reference for additional information on that file system.
The following sections describe the system requirements for the Cisco NCS 520 Series Router software:
These are the recommendation for the router images and packages:
DRAM memory—4 GB
ROMmon Release 1.0 (FAI) is the recommended release for all ROMmon upgradeable components. For more information about ROMmon images, see Release Notes.
The Cisco IOS XE image is stored as a bin file in a directory that is named with the Cisco IOS XE release. The image is stored on the system board bootflash device (bootflash:).
 Note |
If you try to copy or archive upgrade beyond the bootflash memory capacity, the action terminates. |
You can use the show version privileged EXEC command to see the software version that is running on your router. The second line of the display shows the version.
You can also use the dir bootflash: privileged EXEC command to see the names of other software images that you might have stored in bootflash.
The table below provides a list and descriptions of autogenerated files on the router.
 Caution |
Do not alter 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. |
|
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.
|
||
|
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 XE failure.
|
Download the image to the bootflash. For information on downloading images see, Loading and Managing System Images Configuration Guide.
Caution |
Ensure that you have chosen an upgrade image that is supported by your current software version. |
The routers are shipped with the latest software image installed. Follow the instructions in this section if you need to reinstall or upgrade the software image.
Before installing your router software, make sure that you have archived copies of the current Cisco IOS XE release and the Cisco IOS XE release to which you are upgrading. You should keep these archived images until you have upgraded all devices in the network to the new Cisco IOS XE image and until you have verified that the new Cisco IOS XE image works properly in your network.
Cisco routinely removes old Cisco IOS XE versions from Cisco.com. See End of Sale and End of Life Products at this URL: http://www.cisco.com/en/US/products/sw/iosswrel/prod_category_end_of_life.html.
You can copy the software image file on the bootflash memory to the appropriate TFTP directory on a host by using the copy bootflash: tftp: privileged EXEC command. You can also configure the router as a TFTP server to copy files from one router to another without using an external TFTP server by using the tftp-server global configuration command. For more information about the tftp-server command, see the “Basic File Transfer Services Commands” section of the Cisco IOS Configuration Fundamentals Command Reference at this URL: http://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_book.html.
This procedure is for copying the combined bin file to the router. You copy the file to the router from a TFTP server and extract the files. You can download an image file and replace or keep the current image.
To download software, follow these steps:
| Step 1 |
Locate the software image file:
|
||
| Step 2 |
Download the image to a TFTP server and make sure that the server is properly configured. |
||
| Step 3 |
Log into the router through the console port or a Telnet session. |
||
| Step 4 |
If Gigabit Ethernet (GE) port 0 is used as management interface, check the connectivity to TFTP server using the following CLI: For more information about assigning an IP address and default gateway to the router, refer to the software configuration guide for this release. |
||
| Step 5 |
Download the image file from the TFTP server to the router by entering this privileged EXEC command:
The installation process extracts the bin file with all the files and the IOS XE image, and sets the BOOT directory to the created directory in bootflash memory. The process takes approximately 5 to 10 minutes, and at some stages might appear to have stopped. |
||
| Step 6 |
Set the image path in the boot variables and configure the router to autoboot as follows: |
||
| Step 7 |
Verify the boot variables set on the router using the following CLI: |
||
| Step 8 |
Save the configuration and reload the router. |
After the installation, the router is running the universal image. To install a purchased license with increased capabilities, see Software Activation Configuration Guide. To purchase a license, contact Cisco.
Caution |
To avoid actions that might make your system unable to boot, read this entire section before starting the upgrade. |
Follow the procedure to upgrade the ROMMON image:
Copy the latest ROMMON package into bootlfash.
Router# copy tftp://192.168.0.100/FPGA_ROMMON_PKG/ncs520dominica-rommon_0_11.SSA.pkg bootflash:
Router# upgrade rom-monitor filename bootflash:<pkg> allReload the router for the ROMMON to take effect.
The following section provide a sample of software upgrade on the router.
Router# show bootvar
