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.
- 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.
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.
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.
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.
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.

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.
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.
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.
Step 1 Use Table 6 to identify the file that you want to download.
- 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.
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.
- DS3 Framing on OC3 Ports—This feature supports the configuration of DS3 framing on OC3 ports on the Cisco ME3600X-24CX switch.
- IP SLA—Service Performance Testing Infrastructure- Starting with Cisco IOS Release 15.4(1)S, the following features are supported on the Cisco ME 3600-24CX switch:
- MPLS TE - Bundled Interface—Starting with Cisco IOS Release 15.4(1)S, the MPLS Traffic engineering (TE) Bundled Interface Support feature enables Multiprotocol Label Switching (MPLS) traffic engineering tunnels over the bundled interfaces EtherChannel on the Cisco ME3800, Cisco ME3600 series switches.
- PTP Redundancy—Starting with Cisco IOS Release 15.4(1)S, you can configure the Slave Clock mode and the Boundary Clock mode in PTP Redundancy.
- 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.
- 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.
- Sonet Framing Support on OC3 ports—This feature supports Sonet mode framing on OC3 ports on the Cisco ME3600-24CX switch.
Please wait till you receive the "Image Extraction Done" success message, or any other message reporting Failure !!!!!
Symptom: The IP SLA frame transmission does not happen when the IP SLA is configured with a packet profile having outer-vlan, outer-cos and inner-vlan. The Transmission (Tx) count in the statistics goes zero.*Jul 1 23:25:13:402: Table type:0, total entries:1024 *Jul 1 23:25:13:402: Table type:1, total entries:1024
When the Cisco ME600x or ME3800x switch is reloaded with an ethernet service instance in an administratively shutdown state, it reports MAC-flap messages between the administratively down service instance and the another port, if there is a loop with the service instance active.
Symptom: In a REP setup, when you have a port in the FAILED state due to NO_NEIGHBOR, and in this state if the other port of the REP segment is brought up and moves to OPEN state, or if the other port is already in OPEN state is shutdown, the FAILED port is gets unblocked in the hardware. This results in a layer 2 loop.
Conditions: This issue occurs when the SAToP/CESOP CEM pseudowires are initiated from a PE device and egresses out of the PE device into a layer 2 network, the MPLS transport VLANs COS value is expected to be 5 by default but it is not in this case.
Conditions: This issue occurs when BPDUs are tunnelled or forwarded across an EVC cross connect. This issue is not seen with other forms of cross connects, but is specific to Layer 2 Protocol Tunneling (L2PT) forward/tunnel.
Conditions: The traffic comes over the Core VCs (as they are `up') and then flows over the Standby spoke VC from Hub to Spoke. In the spoke, the traffic received from the spoke VC gets punted to the CPU.
Symptom: The Cisco ME 3600X switch tags packets on the native VLAN of a dot1Q trunk when the packets are routed. Local generated packets goes untagged, and packets that have only been switched through the Cisco ME 3600X goes untagged. But, if the packet enters the Cisco ME 3600X on another VLAN and is routed to the destination VLAN, it gets tagged when leaving on a dot1Q trunk.
Symptom: When changing a QoS policy for classification, such as altering a class-map or changing an associated ACL, while the policy is attached to an interface, the classification stops working and remarks traffic in a strange way.
Symptom: Missing packets and jitterbuffer underrun counters are incrementing on a Cisco ME3600CX node where E1 pseudowire (SATOP) is created between a Cisco ME7600 and the Cisco ME3600CX over the MPLS cloud.
Symptom: On the Cisco ME3600X or 3800X switch, RIP packets are not punted to CPU from routing TCAM. This is because the CPU is not attached to the TCAM. This results in all the control plane using multicast RR entry to go down.
Symptom: The .bin file that is extracted from .tar file does not have the right image name. And, when upgrading from 15.3(3)S to 15.3(3)S1 using the archive download-sw <TAR file> the router drops to rommon.
Workaround: There is no workaround for the wrong image name. Switch dropping to rommon during the upgrade through archive download-sw command can be avoided by using archive download-sw or leave-old-sw <TAR file> command.
