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.
New Software Features
The following sections provide information on new software features:
Cisco IOS Release15.4(3)S
The following new software features are introduced in the Cisco IOS Release 15.4(3)S:
Starting with Cisco IOS Release 15.4(3)S, this feature supports 802.1ad on ports with EFP xconnect.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/sw802_one_ad.html
The BFD Multihop Support for IPv4 Static Routes feature enables detection of IPv4 network failure between paths that are not directly connected. If a Bidirectional Forwarding Detection (BFD) session is up (that is, the next-hop destination is reachable), IPv4 static routes that are associated with IPv4 static BFD configuration are added to a routing table. If the BFD session is down, the routing table removes all associated static routes from the routing table.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/chassis/configuration/guide/3600x_24cxscg/irb-bfd-mhop-ip4-static.html
This feature describes implicit mapping of EXP to CoS of MPLS transport VLAN tag. The default copying of CoS from EXP (imposition), which is set by a policy, on the ingress side of pseudowire, is enabled.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/CoS_Marking_for_Pseedowires_over_L2_Network.html
HSRP version 2 provides enhancements, and expands the capabilities beyond what is possible with HSRP version 1. HSRP version 2 has a different packet format than HSRP version 1.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/swhsrp.html
The G.8032 Ethernet Ring Protection (ERP) protocol uses CFM Continuity Check Messages (CCMs) for failure detection. At 3.3 ms CCM interval, SONET-like 50 ms switching time performance can be achieved. The support for G.8032 with 3.3 ms timers is only for the Cisco ME3600X-24CX switches.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/swering_prot.html
IPv6 routing protocols ensure device-to-device resilience and failover. However, in situations in which the path between a host and the first-hop device fails, or the first-hop device itself fails, first hop redundancy protocols (FHRPs) ensure host-to-device resilience and failover. The Hot Standby Router Protocol (HSRP) protects data traffic in case of a gateway failure.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/swhsrp.html
This feature describes how to configure an IETF Two-Way Active Measurement Protocol (TWAMP) responder on a Cisco device to measure IP performance between the Cisco device and a non-Cisco TWAMP control device on your network. TWAMP-Control protocol is used to set up performance measurement sessions. The TWAMP-Test protocol is used to send and receive performance-measurement probes.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/swering_prot.html
In order to ensure that OSPFv3 packets are not altered and re-sent to the router, causing the router to behave in a way not desired by its system administrators, OSPFv3 packets must be authenticated. OSPFv3 uses the IPsec (only in crypto k9 images) secure socket API to add authentication to OSPFv3 packets. This API supports IPv6.
For more information, see http://www.cisco.com/c/en/us/td/docs/switches/metro/me3600x_3800x/software/release/15-4_3_S/configuration/guide/3800x3600xscg/swipv6.html

Open Caveats in Cisco IOS Release 15.4(3)S
Symptom: The CPU usage goes high and the status of UP MEP configured in the device flaps. Due to this, achieving end-to-end service monitoring in provider level because of UP MEP status flaps is not possible.
Conditions: This issue is seen with aggressive timers. This issue occurs when there are more than one Down MEP with 3.3 ms CC interval in the customer level attached to the PE device such that the point of attachment has MIPs for the customer level and an UP MEP for the provider level.
Workaround: Remove the MIP configuration for the customer level.
Symptom: The link status of the port-channel always flaps when there is a configuration for Portchannel with EFP done by copying and pasting the CLI commands in the device console.
Conditions: This issue occurs when copying and pasting the portchannel configurations with EFP, such that the CLI sequence has bridge domain command immediately followed by "l2protocol peer lacp".
Workaround: Execute the command "l2protocol peer lacp" before configuring the bridge domain for the service instance.
Symptom: Data traffic is not forwarded bidirectionally through a Port-channel.
Conditions: This issue occurs when the port-channel with EFP is created by copy-pasting the CLI commands in the device console.
Workaround: Default the port-channel interface and configure the portchannel with EFP by manually executing the CLI commands one by one.
Symptom: Traffic drops for 30 seconds in the G.8032 Ring.
Conditions: This issue occurs when the ring moves from protection to pending state because of the recovery of a ring node (ring node comes up after reload).
Workaround: There is no workaround.
Symptom: Port MEPs cannot be used at domain level 7. The remote port MEPs will not be learned by the local port MEPs at level 7.
Conditions: This issue occurs when the port MEP is created at level 7.
Workaround: Configure the port MEP in other domain level from 0-6.
Symptom: Policy attachment to EFP built over port-channel fails for the first time on different EFPs.
Conditions: This issue occurs when the policy is re-attached for the first time on a given EFP.
Workaround: Attach the policy again after the failure occurs.
Resolved Caveats in Cisco IOS Release 15.4(3)S
Symptoms: Gigabit and 10 Gigabit Fiber link reporting threshold violation alarm. The “%SFF8472-3-THRESHOLD_VIOLATION: Gi0/11: Rx power high alarm” error message is seen on ports.
Conditions: This symptom occurs on Cisco ME3600, and Cisco ME3800 devices. The messages are seen with the interface shut or no shut.
SFF8472-3-THRESHOLD_VIOLATION Gi5/1: Rx power low alarm; Operating value:
-28.5 dBm, Threshold value: -24.0 dBm
Workaround: Fixing the fiber signal issue or disconnecting the fiber from the transceiver has been known to stop the messages.
Symptom: Currently, on the Cisco ME3800X switch, following errors are displayed when the interface vasileft" and interface vasiright commands are used.
Conditions: This issue occurs during ME3800 VASI configuration.
Workaround: Do not configure VASI on the Cisco ME3800X switch, as the support for this command will be removed in future releases.
Symptom: Ping fails for around 35 seconds.
Conditions: This issue occurs due to a change in topology, and when Alternate port becomes Root port in RSTP mode.
Workaround: In the problem state, use the clear arp command to resume the traffic.
Symptom: Routed Pseudowire (RPW) ping fails from PE to CE, when SplitHorizon Group 2 is configured in access, and if RPW is with Virtual Private LAN Service (VPLS) Virtual Circuit (VC).
Conditions: This issue occurs when the ping fails.
Workaround: Configure SH Group 1.
Symptom: Neither the SNMPwalk of EntityPhysical MIB nor the Show Inventory command reports the existence of the ME-FANTRAY-XL part.
Conditions: This issue occurs under normal conditions.
Workaround: There is no workaround.
Symptom: Traffic forwarding issue is observed with static MAC address on port-channel. Following are the configuration steps:
2. Configure static MAC address
After the reboot, traffic generated using the static MAC address are not egressing out of the port-channel.
Conditions: This issue occurs after the reboot egress forwarding stops.
Workaround: Reconfigure the static MAC address.
Symptom: High CPU utilization is seen on the Cisco ME 3600 switch.
Conditions: This issue is seen when traffic flows through a service instance, which has MAC security configured.
Workaround: There is no workaround.
Symptom: CPU Hogs and Tracebacks seen on the Cisco ME 3600 switch.
Conditions: This issue occurs when multiple ports are part of the MSTP. and the ports are shut/no shut.
Workaround: There is no workaround.
Symptom: Egress classification is not working on ‘switchport trunk’ interface with and without allowed VLANs configured.
Conditions: This issue occurs when the egress QoS applied on the interface where ‘switchport trunk’ interface is configured.
Workaround: There is no workaround.
Symptom: BFD Fails to Establish Neighbor when running ISIS. After an interface flap or a device reload, a BFD neighbor fails to establish. Protocols registered to BFD like ISIS also fails to establish.
Conditions: This issue only impacts the Cisco ME3600-cx platforms running ISIS with BFD. The issue is seen with the command show platform ho-fpga tx-buffer-table detail 258.
Workaround: Flapping the interface (shut/no shut), or removing and reapplying BFD can resolve the issue.
Symptom: Priority tagged traffic fails with type-5 VC.
Conditions: This issue occurs when priority tagged (vlan id 0) is sent over vc type-5 with encapsulation default in EVC.
Workaround: Convert the vc type from type-5 to type-4.
Symptom: MVPN traffic is not received properly by the receivers as the core replication does not work.
Conditions: This issue occurs when a lot of scale is present, or when the data MDT is used with scale for mVPN.
Workaround: Default MDT can be used.
Symptom: The license boot level tag ‘license boot level’ appears in show run command, and this
Conditions: This issue occurs under normal conditions.
Workaround: There is no workaround.
Symptom: The vlanTrunkPortDynamicState OID is not available when the interface goes up. The switch displays the error “No Such Instance currently exists at this OID”.
Conditions: This issue occurs under normal conditions. It was first discovered in the Cisco IOS 15.3(3)S release.
Workaround: There is no workaround.
Symptom: The Cisco ME 3600X switch does not respond.
Conditions: This issue occurs when a port-channel interface is configured in a bridge-domain where other interfaces are configured for ‘l2protocol tunnel lldp’ and LLDP packets are received.
Workaround: Remove ‘l2protocol tunnel lldp’ configuration from the interfaces in the bridge-domain.
Symptom: STP BPDU loss is observed when you want to tunnel or forward BPDUs across a EVC xconnect.
Conditions: The issue occurs when you want to tunnel or forward BPDUs across a EVC xconnect. This issue is specific to l2pt forward or tunnel and is not seen with other forms of Xconnect.
Workaround: There is no workaround.
Symptom: The Y1731 Performance Monitoring (PM) does not collect the statistics when the EVC tag X popped on ingress traffic before transiting MPLS PW and pushed EVC tag Y at egress traffic.
Conditions: The issue occurs when you send the CFM untagged packets over a pseuduowire.
Workaround: IP SLA works fine when the cos value matches with the CFM domain level.
Symptom: The CISCO-EVC-MIB for ME3600X switch is not available with MetroIPAccess license.
Conditions: This issue is observed only with MetroIPAccess license.
Workaround: Upgrade the license to AdvancedMetroIP license.
Symptom: ICMP destination unreachable message is not generated by the device.
Conditions: This issue occurs when a packet is dropped because there is no route in the routing table.
Workaround: There is no workaround.
Symptom: A few transceiver related alarms are not reported in the CLI after running the show facility-alarm status command. SNMP traps are not generated either for the same events.
Conditions: This issue occurs when the Cisco ME 3800X switch is running Cisco IOS Release 15.3(3)S1 and later.
Workaround: There is no workaround.
Symptom: Targeted LDP session between Customer Edge devices flap every three minutes. IGP Interface LDP between CE devices run fine.
Conditions: This issue occurs when MPLS LDP packet is carried over L2VPN cloud with Control word OFF.
Workaround: Configure control word ON in L2VPN cloud.
Symptom: The Cisco ME3600x switch multicast traffic 224.0.0.x is not passing when the Bridge-domain is 8000.
Conditions: This issue occurs when we have EVC configured with BD 8000.
Workaround: Use bridge-domain between 1 to 7999.
Symptom: Enabling PBR breaks the EIGRP multicast.
Conditions: This issue occurs when:
1. A Route map is created for any random IP address (not necessarily related to multicast/protocol IP).
2. The PBR is enabled on an interface with EIGRP peering.
Workaround: There is no workaround.
Symptom: The Cisco ME3600X does not display time source information when running PTP.
Conditions: This issue occurs when the ME3600X does not display time source information when running PTP protocol. There is no functional issues noticed with PTP time synchronization. The time source field says “Unknown”.
Workaround: There is no workaround.
Symptom: System crashes on configuring card type t1/e1 without t1/e1 license on the switch.
Conditions: This issue occurs on configuring card type t1/e1 without t1/e1 license on box
Workaround: Configure card type after having t1/e1 license on box.
Symptoms: The Bridge-domain does not learn the MAC address but still forwards the traffic.
Conditions: This issue occurs when the cross-connect is configured on the switchport. On configuring the switchport for the first time, the configuration is rejected.
Workaround: Reapply the configuration.
Symptom: The snmpEngineBoots integer does not increment on the Cisco ME 3600X and ME3800X after the device is reloaded. Instead, it is reinitialized.
Conditions: This issue occurs only when the device is rebooted.
Workaround: Perform a warm restart of the device to increment the snmpEngineBoots integer.
Symptom: The v6 multicast traffic is punted to host queue.
Conditions: This issue occurs on a L2 box with no multicast configuration.
Workaround: There is no workaround.
Symptom: When the interface transceiver monitoring is disabled, the interface transceiver reappears after a reload.
Conditions: This issue occurs when the interface transceiver monitoring is disabled with the following commands:
After a reload, the commands reappear in the configuration.
Workaround: An EEM script can be applied to remove the commands from the configuration at bootup. This EEM script looks for the syslog message indicating the device was reloaded.
If AAA command authorization is enabled, configure the event manager session command. Else, the EEM script fails.
Symptom: CE-to-CE ping fails when the TE Tunnel is Up on core.
Conditions: This issue occurs when the ARP is not resolved.
Workaround: Perform a shut of the tunnel interface.
Symptom: Occasionally on certain switches, the 10G REP flaps without any apparent trigger in Layer1.
Conditions: This issue occurs when the 10 Gigabit on the Cisco ME3600X is configured for REP.
Workaround: There is no workaround.
Symptom: Removing the service policy on the interface with traffic causes the device to freeze. CPUHOG messages are seen in the logs that is followed by a crash due to watchdog timeout.
