Installing Software Images and Licenses
The Cisco ME 3800X, ME 3600X and ME 3600X-24CX switches 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 switch software, make sure that you have archived copies of the current Cisco IOS release and the Cisco IOS 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 image and until you have verified that the new Cisco IOS image works properly in your network.
Cisco routinely removes old Cisco IOS versions from Cisco.com. See End of Sale and End of Life Products at this URL:
You can copy the software image file on the flash memory to the appropriate TFTP directory on a host by using the copy flash: tftp: privileged EXEC command. You can also configure the switch as a TFTP server to copy files from one switch 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:
This procedure is for copying the combined tar file to the switch. You copy the file to the switch 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 Use Table 6 to identify the file that you want to download.
Step 2 Locate the software image file:
a. If you are a registered customer, go to this URL and log in.
b. For ME 3800X, navigate to Switches > Service Provider Switches - Ethernet Aggregation.
For ME 3600X, navigate to Switches > Service Provider Switches - Ethernet Access.
c. Navigate to your switch model.
d. Click IOS Software, then select the latest IOS release.
Note When you select a crypto graphic image, you must also accept the terms and conditions of using crypto graphic images.
Step 3 Download the image to a TFTP server and make sure that the server is properly configured.
For more information, refer to Appendix B in the software configuration guide for this release.
Step 4 Log into the switch through the console port or a Telnet session.
Step 5 (Optional) Ensure that you have IP connectivity to the TFTP server by entering this privileged EXEC command:
Switch# ping tftp-server-address
For more information about assigning an IP address and default gateway to the switch, refer to the software configuration guide for this release.
Step 6 Download the image file from the TFTP server to the switch by entering this privileged EXEC command:
Switch# archive download-sw tftp:[[//location]/directory]/image-name.tar
- For // location, specify the IP address of the TFTP server.
- For / directory / image-name .tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive.
- The /overwrite option overwrites the software image in flash memory with the downloaded one.
- The /reload option reloads the system after downloading the image unless the configuration has been changed and not saved.
This example shows how to download an image from a TFTP server at 192.0.2.1 and to overwrite the image on the switch:
Switch# archive download-sw /overwrite tftp://192.0.2.1/image-name.tar
You can also download the image file from the TFTP server to the switch and keep the current image by using the /leave-old-sw option instead of the /overwrite option.
Note There can be only two image directories in the flash memory.
The installation process extracts the tar file with all the files and the IOS image, and sets the BOOT directory to the created directory in flash memory. The process takes approximately 5 to 10 minutes, and at some stages might appear to have stopped.
Step 7 The switch is configured to boot automatically, but you can enter the show boot privileged EXEC command to verify the boot path list and see if a manual boot is necessary.
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Step 8 Save the configuration and reload the switch.
After the installation, the switch is running the universal image. Follow these steps to install a purchased license with increased capabilities. To purchase a license, contact Cisco.
Step 1 Copy the license file to flash or TFTP.
Step 2 Enter this command to install the license:
Switch# license install flash:LICENSE_FILENAME
Switch# license install tftp://location/LICENSE_FILENAME
Step 3 Enter these commands to boot from the new license:
Switch(config)# license boot level license_name
Step 4 If you have a a scaled license, install the scaled license
Switch# license install flash:SCALED_LICENSE_FILENAME
Switch# license install tftp://location/SCALED_LICENSE_FILENAME
Note To revert to a non-scaled license, enter the license clear scaled_license_name privileged EXEC command.
Step 5 Reload the switch for new license to take effect.
