Hardware Support
Software Licenses and Features
If you have a service support contract and order a software license, or if you order a switch, you receive the universal software image, available in crypto and noncrypto versions. If you do not have a service support contract, such as a SMARTnet contract, download the image from Cisco.com.
The ME 3600X supports these licenses:
- Metro IP access is the universal image.
- Advanced Metro IP access license.
- 10 Gigabit Ethernet upgrade license—enables 10 Gigabit Ethernet on the SFP+ uplink ports.
For differences in feature support for each license, see Table 2 and Table 3.
The ME3600X-24CX supports the above licences including the following:
The ME 3800X supports these licenses and a scaled license that can be installed with any of these licenses to increase the supported values for that license, for example, more MAC addresses, VLANs, IPv4 routes, and so on.
- Metro Ethernet services is the universal image.
- Metro IP services license.
- Metro Aggregation services license.
- Scaled license for any of the above licenses.
For differences in feature support for each license, see Table 4 and Table 5.
To install a software image, see the “Upgrading the Switch Software” section and the “Working with the Cisco IOS File System, Configuration Files, and Software Images” chapter in the software configuration guide.
To install a software license, see the “Cisco IOS Software Activation Tasks and Commands” chapter in the Cisco IOS Software Activation Configuration Guide:
http://www.cisco.com/en/US/docs/ios/csa/configuration/guide/csa_commands.html
An emergency evaluation license is embedded in the software image and does not require the installation of a license file. Specify which evaluation license to enable by using the license boot level command.
Enabling evaluation license on an ME 3800X:
Note Only MetroAggrServices is supported during evaluation. Accept the EULA.
Enabling evaluation license on an ME 3600X:
Note Only AdvancedMetroIPAccess is supported during evaluation. Accept the EULA.
After entering the license boot level command, you are prompted to accept the End-User Licensing Agreement (EULA). After accepting the EULA, exiting configuration mode, and saving the running configuration to memory, reload the switch to apply the evaluation license.
Note The evaluation period is valid for 60 days. When the 60 day evaluation period ends, the evaluation license will be unusable after the next reload.
Upon installation of a license file, the license will automatically update to the new license type. There is no need to clear the evaluation license.

Upgrading the Switch Software
- “Finding the Software Version and Feature Set” section
- “Deciding Which Files to Use” section
- “Installing Software Images and Licenses” section
Finding the Software Version and Feature Set
The Cisco IOS image is stored as a bin file in a directory that is named with the Cisco IOS release. The image is stored on the system board flash device (flash:).
Note The flash memory can store a maximum of two IOS images or tar files. If you try to copy or archive upgrade beyond the flash memory capacity, the action aborts.
You can use the show version privileged EXEC command to see the software version that is running on your switch. The second line of the display shows the version.
You can also use the dir filesystem : privileged EXEC command to see the directory names of other software images that you might have stored in flash memory.
Deciding Which Files to Use
The software installation procedures in these release notes describe how to perform the upgrade by using a combined tar file. This file contains the Cisco IOS image file. To upgrade the switch through the command-line interface (CLI), use the tar file and the archive download-sw privileged EXEC command.
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:
http://www.cisco.com/en/US/products/sw/iosswrel/prod_category_end_of_life.html
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:
ht tp://www.cisco.com/en/US/docs/ios/fundamentals/command/reference/cf_book.html
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.
http://software.cisco.com/download/navigator.html
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:
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:
- 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:
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.
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:
Step 3 Enter these commands to boot from the new license:
Step 4 If you have a a scaled license, install the scaled license
Note To revert to a non-scaled license, enter the license clear scaled_license_name privileged EXEC command.
