For upgrade path details, refer the NCS Software Matrix

Some of the key limitations to be considered before proceeding with the upgrade are:

  • When a node is upgraded from R9.80 (SONET or SDH), R10.0 (SONET or SDH) MSTP to NCS fixed grid, the database backup taken from the originating release cannot be restored after the upgrade.

  • When a node is upgraded from NCS fixed grid to NCS flex, the database back-up taken from the originating release cannot be restored after the upgrade.

  • When a node is upgraded from NCS fixed grid to NCS fixed grid or from NCS flex to NCS flex, the database is retained during the upgrade.


Caution

Do not attempt to upgrade a configuration that contains Cisco ONS 15454 M12 nodes to Cisco NCS software.

Errorless Upgrades and Exceptions

This section describes important information to be aware of before you begin the upgrade process:

  • When a node installed with GE_XP, GE_XPE, 10GE_XP, or 10GE_XPE cards configured with REP or a channel group is upgraded from R9.2.0 or later releases, traffic loss occurs. The traffic loss is less than 60 seconds for each GE_XP, GE_XPE, 10GE_XP, or 10GE_XPE card that undergoes a soft reset during the upgrade process.

  • After you upgrade to R9.6.0 or later releases, use the Force FPGA Update button in the CTC card view > Provisioning > Card tab to update the SWAN FPGA image on OTU2_XP cards. This allows detection of the HI-BER alarm when OTU2_XP cards are configured in the 10G Ethernet LAN Phy to WAN Phy mode.
  • The MXP_MR_2.5 and MXPP_MR_2.5 cards automatically download a new field-programmable gate array (FPGA) image during an upgrade from a software release prior to R7.0 to . The upgrades for DWDM configurations are expected to be errorless with the following exceptions if nodes are running MXP_MR_2.5 and MXPP_MR_2.5 cards:
    • If Y-cable protection is not provisioned, the data path incurs a traffic hit of up to 10 seconds or less.

    • If Y-cable protection is provisioned on cards running Fiber Channel (FC) payloads, traffic switches away from the card downloading the new FPGA causing the FC link to be reinitialized.

    • If Y-cable protection is provisioned on cards running Gigabit Ethernet (GE) payloads, there is no traffic interruption.

Cisco NCS Software Packages


Caution

Do not download and activate the Cisco NCS software package on a Cisco ONS 15454 M12 shelf.

The Cisco NCS software is shipped in two packages:

  • NCS Flex: contains software that supports flex cards and configurations in NCS 2002 and NCS 2006 . WSON is supported in this package.

  • NCS Fixed Grid: contains software that supports fixed grid cards and configurations in NCS 2002 and NCS 2006. WSON is supported in this package.

Note

You can download the NCS fixed grid package on a NCS flex node and vice versa. The node database is deleted during the activation. After the activation, it is recommended to relaunch CTC to view the new package that is activated. The database is not lost during activation, for Optical Line Amplifier (OLA) nodes with these cards- OPT-AMP-C, OPT-EDFA-xx, OPT-RAMAN-CTP, OPT-RAMAN-COP.

This table describes the node controller and shelf controller for NCS packages.

Document Procedures

Procedures in this document must be performed in consecutive order unless noted otherwise. Ensure that the procedure is completed for each node in a given network. If you are new to upgrading the software, make a printed copy of this document and use it as a checklist.

Each non-trouble procedure (NTP) is a list of steps designed to accomplish a specific procedure. Follow the steps until the procedure is complete. If you need more detailed instructions, refer to the detail-level procedure (DLP) specified in the procedure steps. Throughout this guide, NTPs are referred as “procedures” and DLPs as “tasks.” Every reference to a procedure includes its NTP number, and every reference to a task includes its DLP number.

The DLP (task) supplies additional task details to support the NTP. The DLP lists numbered steps that lead you through completion of a task. Some steps require that equipment indications be checked for verification. When a proper response is not obtained, a trouble clearing reference is provided.

This section lists the document procedures (NTPs). Turn to a procedure for applicable tasks (DLPs).

  1. NTP-U487 Preparing to Upgrade to a New Release—This procedure contains critical information and tasks that you must read and complete before beginning the upgrade process.

  2. NTP-U488 Back Up the Cisco NCS Software Database—Complete the database backup to ensure that you have preserved your node and network provisioning in the event that you need to restore them.

  3. NTP-U489 Upgrade the Cisco NCS Software—Complete this procedure to complete the upgrade.

  4. NTP-U490 Install Public-Key Security Certificate— Complete this procedure to be able to run the software.

  5. NTP-U491 Restore the Previous Software Load and Database— Complete this procedure if you want to return to the previous software load you were running before activating the new release.

NTP-U487 Preparing to Upgrade to a New Release

Purpose

This procedure provides critical information checks and tasks you must complete before beginning an upgrade to the latest release.

Procedure


Step 1

Before you begin, make sure that information related to your site, for example, date, street address, site phone number, and dialup number are stored in a safe and accessible location. The data will be useful during and after the upgrade.

Step 2

Read the release notes of the release you are upgrading to. Visit Release Notes to download the release notes.

Step 3

Ensure your workstation meets the minimum hardware and software requirements before starting the upgrade. For more information on the hardware and software requirements, read the release notes.

Step 4

Refer to the Software Upgrade Matrix to verify if the upgrade path is supported.

Step 5

Make sure that the control cards are installed in the appropriate slots on all the nodes in the network and on both the slots as indicated here. For a complete list of supported control cards, see Supported Control Cards:

  • NCS 2015 shelf — control cards in Slots 1 and 17

  • NCS 2006 shelf— control cards in Slots 1 and 8

  • NCS 2002 shelf— control cards in Slot 1

Note 

When upgrading network elements with a subtended M12 shelf and TCC3 as shelf-controller, the following steps are to be followed:

  1. Upgrade the M6 or M15 node controller without the M12 connected.

  2. At the end of the upgrade, connect the M12 shelf.

  3. Wait till the M12 configuration is complete.

It is not possible to revert from R10.6.2 to a previous release, with an M12 as a subtended shelf. The download of a legacy package on a subtended M12 in a flex node is not allowed.

Step 6

Repeat the above step for every node in the network.

Step 7

Collect the node diagnostics logs from the node. This action is very useful incase the upgrade fails, as the diagnostics help in understanding if the node had issues before the upgrade.

Step 8

Export the current alarms and conditions to your local storage. After the upgrade, if new alarms or conditions arise, then comparing the time stamp of the alarm to the previously saved time stamp helps in identifying new alarms or conditions.

Step 9

Perform a backup of the node database. This is very useful incase the upgrade fails, then the database can be restored using the backup. The detailed procedure for backing up the database is discussed in the next section.

Stop. You have completed this procedure.

Caution

Do not perform maintenance or provisioning activities during the activation task.



Note

When you perform software activation on nodes, if there is any circuit in the partial state, then you should relaunch the CTC. Ensure that all the nodes in the network are in the R11.12 version.


Procedure


Step 1

Insert the software CD into the workstation CD-ROM drive (or otherwise acquire access to the software) to begin the upgrade process.

Note 

Inserting the software CD activates the CTC Java Setup Wizard. Use the setup wizard to install the components or click Cancel to continue with the upgrade.

Step 2

Complete the DLP-U546 Download the NCS Software task for all nodes to be upgraded.

Step 3

Complete the DLP-U548 Activate the New Cisco NCS Software task for all nodes to be upgraded.

Note 

Only one node can be activated at a time. During a parallel upgrade, activate another node as soon as the controller cards reboot successfully. To perform parallel upgrade remotely, wait five minutes for the controller cards to reboot completely.

Step 4

Complete the DLP-U549 Delete Cached JAR Files task, as necessary.

Step 5

(Optional) If you want to prevent a software revert to an earlier software release, complete the DLP-U546 Download the NCS Software task on all nodes, or groups of nodes you are upgrading a second time.

Caution 

If the software is downloaded again after a version is activated, a revert to the previous version cannot be performed.

Step 6

If you need to return to the software and database you had before activating Software R11.1, proceed with the NTP-U491 Restore the Previous Software Load and Database procedure.

Step 7

To back up the Software R11.1 database for the working software load, see NTP-U488 Back Up the Cisco NCS Software Database procedure in order to preserve the database for the current release.

After the upgrade is complete, the date and time in CTC is reset.

Stop. You have completed this procedure.


What to do next

After upgrading the software to a different build, if there is a change in the FPGA, the FPGA is upgraded automatically. During the FPGA upgrade process, the card goes for a cold reboot. If Optical Supervisory Channel (OSC) is provisioned, then the transient PPM-IMPROPER-REMOVAL alarm is raised, which gets cleared in a short span of time. This happens because of the power glitches to the PPM while the card is coming up after the cold reboot.

DLP-U546 Download the NCS Software

Purpose

This task downloads software to the NCS nodes before activation.

Note

If you are running CTC on Windows or VM and the corresponding node is sending the packet with size greater than 1492 bytes, then the packet does not reach the node that is connected to OSC. For example, in a GNE-ENE connection over the OSC link, software download can fail on the ENE if the VM is sending the packet with size greater than 1492 bytes.



Note

The control card contains flash memory with two partitions—Working and protect (backup). The software is downloaded to the protect (backup) partition of the flash memory on both the standby and active cards. This download is not traffic affecting because the active software continues to run in the primary RAM location. The software can therefore be downloaded at any time.



Note

To download and upgrade the software using TL1, see the procedure.


Before you begin

If you want to download the software onto the node connected to OSC, ensure the node running CTC has set the MTU size to 1492.

Note

It is recommended that the first node that is activated be connected via LAN. This ensures that the new CTC JAR files download to the workstation as quickly as possible.

If a node is provisioned to have no LAN access, the value is overridden in the case of node isolation. Additionally, if the node is not reachable, the LAN access is turned on. It is recommended that you avoid node isolation.



Note

During the activation process, when the node is being upgraded to R11.0 (and later releases), the USB-MOUNT-FAIL alarm is raised. In MSM, the USB-MOUNT-FAIL alarm is raised on all subtended shelf controllers and the node controller. When all the subtended shelf controllers and the node controller complete the upgrade successfully, the USB-MOUNT-FAIL alarm is cleared. No manual intervention is required to clear the USB-MOUNT-FAIL alarm. After the USB-MOUNT-FAIL alarm is cleared, USB sync is triggered. After USB sync is successfully completed, the node is migrated to the latest software successfully.


Procedure


Step 1

If CTC is not already started, start CTC.

Step 2

Record the IP address of the node. The IP address can be obtained either on the LCD or on the upper left corner of the CTC window.

Step 3

Make sure that the alarm filter is turned off. To do so, complete the following:

  1. Click the Filter tool at the lower-left side of the window.

    The Alarm Filter dialog box appears.

  2. Click to select any check box that is not selected in the Show Severity section of the General tab.

Step 4

Make sure that all cards that are part of a 1+1 or Y-cable protection group must be active on the working card of the protection group and no protection switches are occurring. Also, ensure that traffic carrying protect cards are in a standby state. To do so, complete the following:

  1. In the node view, click Maintenance > Protection tabs.

  2. Select each protection group listed and view the active or standby status of each card in the Selected Group area.

During node activation, all the common control cards in the node reboot beginning with the standby card. As soon as the standby card recovers from the reboot, it signals the active card to reset as a standby card and the standby card transitions to active. An Activation Successful message indicates that the software is successfully activated.
Step 9

Click OK.

The connection between CTC and the node is lost and CTC displays the Network view. The INCOMPATIBLE-SW alarm is raised in CTC for the first node that is activated because CTC is unable to connect to the NE due to differing, incompatible versions of the software between CTC and the NE. A CTC alert is displayed to update the CTC software. To clear the INCOMPATIBLE-SW alarm, perform steps 10 through 12 only for the first node that is activated on the network.

During the activation process:

  • The SYSBOOT alarms are raised when the common control cards and cross-connect card reset. These alarms clears when all the cards reset.

    The activation process can take up to 30 minutes, depending on the number of cards installed in the node.

  • The GCC-EOC, EOC, and EOC-E alarms are transient. These alarms are raised and cleared during the upgrade process when the control cards and line cards reset.

  • Protect cards in the Y-cable protection group boot next, in the order that the protection group was created.

  • Other line cards reset one after the other in the order of slot number.

If you are upgrading remotely and cannot see the nodes, wait for 5 minutes for the process to complete, then check to ensure that related alarms have cleared before proceeding.

Step 10

In CTC, choose File > Update CTC. The CTC software is updated. A CTC alert is displayed to restart CTC.

Step 11

Security Level

Superuser


Note

To perform a supported (non-service-affecting) revert from , the release you want to revert to must have been working at the time you activated to the current software version on that node. Also, a supported revert automatically restores the node configuration at the time of the previous activation. The exception to this is when you have downloaded a second time, ensuring that no revert to a previous load can take place. In this case, the revert occurs, but is not traffic-affecting and does not change the database.



Note

Ensure that all cards that are part of a protection group (1+1 or Y-cable) are active on the working card of that protection group and that no protection switches are occurring. To ensure that traffic carrying protect cards are in a standby state, in the node view click the Maintenance tab, and view the Protect column for each of the listed protection groups. View the active/standby status of each card in the Maintenance tab.


Procedure


Step 1

From the node view, click the Maintenance tab, then click the Software button.

Step 2

Verify that the protect software displays the release you upgraded from.

Step 3

Click the Revert button. Revert activates the protect software and restores the database from the previous load. A confirmation dialog box appears.

Note 

Any FPGA downgrades during the revert process may affect traffic. Configuration changes made after activation are lost when you revert.

Step 4

Click OK. This begins the revert process and drops the connection to the node.

Step 5

Wait until the software revert completes before continuing.

Note 

The system reboot may take up to 30 minutes to complete.

Step 6

Wait one minute before reverting another node.

Step 7

After reverting all the nodes in the network, restart the browser and log back into the last node that was reverted. This uploads the appropriate CTC applet to your workstation.

Note

If you are running CTC on Windows or VM and the corresponding node is sending the packet with size greater than 1492 bytes, then the packet does not reach the node that is connected to OSC. For example, in a GNE-ENE connection over the OSC link, database restore can fail on the ENE if the VM is sending the packet with size greater than 1492 bytes.



Caution

Do not perform these steps unless the software revert failed.



Caution

This process is service affecting and should be performed during a maintenance window.


Before you begin

If you want to restore the database onto the node connected to OSC, ensure the node running CTC has set the MTU size to 1492.

Procedure


Step 1

In CTC node view, click the Maintenance tab, then click the Database button.

Step 2

Click the Restore button. The DB Restore dialog box appears.

Step 3

Click Browse to locate the database file stored on the workstation hard drive or on network storage.

Step 4

Click the database file to highlight it and click Open. The DB Restore dialog box appears.

Step 5

If you need a complete database restore, check the Complete database (System and Provisioning) checkbox.

Note 

The following parameters are restored only when the Complete Database (System and Provisioning) checkbox is checked: node name, IP address, subnet mask and gateway, and IIOP port. If you change the node name and then restore a backed up database on this node, the circuits automatically map to the newly renamed node. It is recommended to keep a record of the old and new node names.

Step 6

Click Ok.

The database is restored and the control cards reboot.

Step 7

When the control cards have finished rebooting, log into CTC and verify that the database is restored.

Wait one minute before restoring the next node.

Step 8

Repeat Steps 1 to 7 for each node in the network.

You have now completed the manual database restore.

Note 

When the complete database is restored, the node does not report an event regarding the IP change; the node reboots and configures the new IP from the database.
