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:

  • 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.

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:

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.
 

 

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.

Upgrading the Switch Software

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.

 

Table 6 Cisco IOS Software Image Files

me360x_t-universalk9-tar.154-1.S2.tar

Cisco ME 3600X-24CX universal cryptographic image. This image has the Metro Ethernet features plus Kerberos and SSH.

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:

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.

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 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.

Switch# reload

Installation Notes

You can assign IP information to your switch by using these methods:

  • The CLI-based setup program, as described in the switch hardware installation guide.
  • The DHCP-based autoconfiguration, as described in the switch software configuration guide.
  • Manually assigning an IP address, as described in the switch software configuration guide.

New Software Features

The following sections provide information on new software features:

Cisco IOS Release15.4(1)S

The following new software features are introduced in the Cisco IOS Release 15.4(1)S:

  • DS3 Framing on OC3 Ports—This feature supports the configuration of DS3 framing on OC3 ports on the Cisco ME3600X-24CX switch.

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/chassis/configuration/guide/OC3_Ifc_Module.html

  • 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:

Color-aware traffic generation on layer 2 targets

Color-aware two-way and passive measurement for layer 2 targets

IP traffic generation on layer 3 targets

Color-blind and color-aware passive measurement on layer 3 Targets.

Color Aware IP flow Generation: differentiated services code point (DSCP) based

Color Aware IP flow measurement: DSCP based

IMIX Traffic Generation type (combination of 64, 512, and 1518 byte packets)

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/chassis/configuration/guide/swy1564.html

  • 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.

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/configuration/guide/swmpls_te_bundled_interface.html

  • 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.

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/chassis/configuration/guide/swclocking.html

  • 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.

Note The TDM and CEM pseudowires are not supported on the Cisco ME 3600x and ME 3800x switches.


For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/configuration/guide/swiprout.html

  • 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.

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/configuration/guide/swiprout.html

  • Sonet Framing Support on OC3 ports—This feature supports Sonet mode framing on OC3 ports on the Cisco ME3600-24CX switch.

For more information, see

http://www.cisco.com/en/US/docs/switches/metro/me3600x_3800x/software/release/15.4_1_S/chassis/configuration/guide/OC3_Ifc_Module.html

Open Caveats

The following sections provide information about open caveats:

Open Caveats in Cisco Release 15.4(1)S2

  • CSCum55294

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.

  • CSCun75614

Symptoms: The Bridge-domain does not learn the MAC address, but 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. But, on re-applying, the configuration is accepted.

Workaround: There is no workaround.

  • CSCun81754

Symptom: The snmpEngineBoots integer does not increment on the Cisco ME 3600X and ME3800X after the device is reloaded. It rather gets reinitialized.

Conditions: This issue occurs only when the device gets rebooted. However, if we do warm restart the snmpEngineBoots integer increases.

Workaround: There is no workaround.

  • CSCun96012

Symptom: The VLAN loadbalancing does not working in REP segment 1.

Conditions: This issue occurs when there are more than one segment on the REP ring. This issue is observing only for Segment 1.

Workaround: Either shut down the other segments or perform a shut followed by no shut on the other alternate port on segment 1.


Note Wait for the preemption delay time.


  • CSCuo34646

Symptom: When the interface transceiver monitoring is disabled, the interface transceiver reappear after a reload.

Conditions: This issue occurs when the interface transceiver monitoring is disabled with the following commands:

transceiver type all
no monitoring

 

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.

event manager applet Disable_transceiver_monitoring
event syslog pattern "SYS-5-RESTART"
action 1.0 cli command "enable"
action 2.0 cli command "config t"
action 3.0 cli command "transceiver type all"
action 4.0 cli command "no monitoring"
action 5.0 cli command "end"
action 6.0 syslog msg "EEM disabled transceiver monitoring"

 

If AAA command authorization is enabled, configure ‘event manager session cli username <USER_NAME>’. Else, the EEM script fails.
