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 on page 6.
The ME3600X-24CX supports the above licences including the following:
•
10G license
•
1588BC license
•
T1/E1 counted license
•
OC3 per port license
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 on page 7.
To install a software image, see the “Upgrading the Switch Software” section on page 8 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:
Switch# configure terminal
Switch(conf)# license boot level <MetroEthServices|MetroIPServices|MetroAggrServices>
Note
Only MetroAggrServices is supported during evaluation. Accept the EULA.
Switch(conf)# exit
Switch# write memory
Switch# reload
Note: This evaluation license will be validated only after reload.

OL-31008-04
Enabling evaluation license on an ME 3600X:
Switch# configure terminal
Switch(conf)# license boot level <MetroIPAccess|AdvancedMetroIPAccess>
Note
Only AdvancedMetroIPAccess is supported during evaluation. Accept the EULA.
Switch(conf)# exit
Switch# write memory
Switch# reload
Note: This evaluation license will be validated only after a reload.
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.

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:
http://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 on page 9 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.
Note
Step 3
c.
Navigate to your switch model.
d.
Click IOS Software, then select the latest IOS release.
When you select a crypto graphic image, you must also accept the terms and conditions of using crypto
graphic images.
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:
10
OL-31008-04
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.
Switch# show boot
BOOT path-list
:
flash:/me380x-universal-mz.153-2.S/me380x-universal-mz.153-2.S.bin
Config file
:
flash:/config.text
Private Config file : flash:/private-config.text
Manual Boot
: no
HELPER path-list
:
Step 8
Save the configuration and reload the switch.
Switch# reload
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
or
Switch# license install tftp://location/LICENSE_FILENAME
Step 3
Enter these commands to boot from the new license:
Switch# config t
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
or
Switch# license install tftp://location/SCALED_LICENSE_FILENAME
Note
Step 5
To revert to a non-scaled license, enter the license clear scaled_license_name privileged EXEC
command.
Reload the switch for new license to take effect.
Switch# reload

Note
Remote LFA FRR for TDM on ME 3600X-24CX-M Switch—When a link or a switch fails,
distributed routing algorithms compute new routes that take into account the failure. The Loop-Free
Alternate (LFA) Fast Reroute (FRR) feature offers an alternative to the MPLS Traffic Engineering
Fast Reroute feature to minimize packet loss due to link or node failure. Some topologies (for
example the commonly used ring-based topology) require protection that is not afforded by LFA
FRR alone. Remote LFA FRR enables you to tunnel a packet around a failed link to a remote
loop-free alternate that is more than one hop away. The Cisco ME 3600X-24CX-M switch supports
two pseudowire types that utilize CEM transport: Structure-Agnostic TDM over Packet (SAToP) and
Circuit Emulation Service over Packet-Switched Network (CESoPSN). Starting with Cisco IOS
Release 15.4(1)S, Remote LFA FRR is supported on TDM pseudowires.
The TDM and CEM pseudowires are not supported on the Cisco ME 3600x and ME 3800x switches.

VPLS over Remote LFA—When a link or a switch fails, distributed routing algorithms compute new
routes that take into account the failure. The Loop-Free Alternate (LFA) Fast Reroute (FRR) feature
offers an alternative to the MPLS Traffic Engineering Fast Reroute feature to minimize packet loss
due to link or node failure. Some topologies (for example the commonly used ring-based topology)
require protection that is not afforded by LFA FRR alone. Remote LFA FRR enables you to tunnel
a packet around a failed link to a remote loop-free alternate that is more than one hop away. VPLS
(Virtual Private LAN Service) enables enterprises to link together their Ethernet-based LANs from
multiple sites through the infrastructure provided by their service provider.
