Managing Firmware Upgrades

This section describes managing firmware upgrade settings in IoT FND, and includes the following sections:

Use IoT FND to upgrade the firmware running on routers (CGR1000s, IR800s), AP800s and Cisco Resilient Mesh Endpoints (RMEs) such as meters and range extenders. IoT FND stores the firmware binaries in its database for later transfer to routers in a firmware group through an IoT FND and IoT-DM file transfer, and to RMEs using IoT FND.

Cisco provides the firmware bundles as a zip file. For Cisco IOS, software bundles include hypervisor, system image and IOx images (for example, Guest-OS, Host-OS).

Firmware system images are large (approximately 130 MB); kickstart images are approximately 30 MB. Every firmware bundle includes a manifest file with metadata about the images in the bundle. You can pause, stop, or resume the upload process.

Router Firmware Updates

IoT FND updates router firmware in two steps:

Procedure

Step 1

Uploads the firmware image from IoT FND to the router. Firmware images upload to the flash:/managed/images directory on the router.

Note

 
In some cases the router might be in a Firmware Group. Refer to Configuring Firmware Group Settings.

Because of their large size, firmware-image uploads to routers take approximately 30 minutes, depending on interface speeds

Note

 
If you set the property, collect-cellular-link-metrics, to ‘true’ in cgms.properties, then the following Cellular link quality metrics are collected for CGR1000, IR800 and IR1100, each time you initiate a firmware upload from IoT FND:

  • RSRP: Reference Signal Received Power which is the power of the reference signal

  • RSRQ: Reference Signal Received Quality or the quality of the reference signal which is the a ratio of RSSI to RSRP

  • SINR: Signal-to-Noise Ratio which compares the strength of the signal to the background noise.

  • RSSI: Received Signal Strength Indicator or the strength of the reference signal

Additionally, the following cgna profile is created on the CGR1240 and activated when the firmware upload is triggered.
cgna profile cg-nms-cellularlinkmetrics
add-command show cellular 3/1 all | format
flash:/managed/odm/cg-nms.odm
interval 5
url https://<FND IP address>:9121/cgna/ios/metrics
gzip
active

Note

 
On execution of the cgna profile above, the metrics data is persisted in the Metrics_History table in the database and can be collected by using the getMetricHistory NBAPI.

Step 2

Installs the firmware on the device and reloads it.

During the firmware install the boot parameters on the routers are updated according to the new image file and the router is reloaded after enabling the cg-nms-register cgna profile.

Note

 
You must initiate the firmware installation process. IoT FND does not automatically start the upload after the image upload.

When a router contacts IoT FND for the first time to register and request tunnel provisioning, IoT FND rolls the router back to the default factory configuration (ps-start-config) before uploading and installing the new firmware image.

Note

 
This rollback requires a second reload to update the boot parameters in ps-start-config and apply the latest configuration. This second reload adds an additional 10–15 minutes to the installation and reloading operation.

Upgrading Guest OS Images

Depending on CGR factory configuration, a Guest OS (GOS) may be present in the VM instance. You can install or upgrade Cisco IOS on the CONFIG > FIRMWARE UPDATE page (see Router Firmware Updates). The GOS, hypervisor, and Cisco IOS all upgrade when you perform a Cisco IOS image bundle installation or update.

After any Cisco IOS install or upgrade, when IoT FND discovers a GOS, it checks if the initial communications setup is complete before it performs the required setup. The CGR must have a DHCP pool and GigabitEthernet 0/1 interface configured to provide an IP address and act as the gateway for the GOS. The new GOS image overwrites existing configurations. IoT FND has an internal backup and restore mechanism that ports existing apps to the upgraded Guest OS. See Monitoring a Guest OS for more information.

See Cisco 1000 Series Connected Grid Routers Configuration Guides for information on configuring the CGR.

Note: If IoT FND detects a non-Cisco OS installed on the VM, the firmware bundle will not upload and the Cisco reference GOS will not install.

Upgrading WPAN Images

At the CONFIG > FIRMWARE UPDATE page, you can upload the independent WPAN images (IOS-WPAN-RF, IOS-WPAN-PLC, IOS-WPAN-OFDM, IOS-WPAN-IXM) to IoT FND using the Images sub-tab (left-hand side) and Upload Image button like other image upgrades. This process is known as a non-integrated WPAN firmware upgrade.

Note: The WPAN firmware image integrated with the IOS CGR image option is still supported.

Also, if only the WPAN firmware upgrade from the image bundled with IOS image is desired (for example, when the WPAN firmware upgrade option was not checked during IOS upgrade), the “Install from Router” option is also provided under respective WPAN image types (IOS-WPAN-RF or IOS-WPAN-PLC).

For detailed steps, go to Working with Router Firmware Images.

Changing Action Expiration Timer

You can use the cgnms_preferences.sh script to set or retrieve the action expiration timer value in the IoT FND database:


/opt/cgms
/bin/cgnms_preferences setCgrActionExpirationTimeout 50

Valid options are:

Procedure

Step 1

set <pkg>actionExpirationTimeoutMins<value>

where:

  • <pkg> is the preference package (required for set and get operations).

  • actionExpirationTimeoutMins is the preference key (required for set and get operations).

  • <value> is the preferred value, in minutes (required for set and setCgrActionExpirationTimeout operations).

Step 2

setCgrActionExpirationTimeout <value>

Step 3

get <pkg>actionExpirationTimeoutMins

Step 4

getCgrActionExpirationTimeout

Example

In the following example, the action timer value is retrieved, set, the current value retrieved again, the value removed, and a null value retrieved:

Working with Resilient Mesh Endpoint Firmware Images

This section describes how to add Resilient Mesh Endpoint (RME) firmware images to IoT FND, and how to upload and install the images on routers.

Overview

When you instruct IoT FND to upload a firmware image to the members of an RME firmware group or subnet, IoT FND pushes the image to the group members in the background and tracks the upload progress to ensure that the devices receive the image.

A Resilient Mesh Endpoint (RME) stores three firmware images:

  • Uploaded image: Image most recently uploaded.

  • Running image: Image that is currently operational.

  • Backup image: It serves as a golden (fallback) image for the RME if there is an issue with the running image.


Note

You can initiate up to 3 firmware downloads simultaneously.

Note

IR500s and other RME devices can coexist on a network; however, for firmware management they cannot belong to the same group.

Note

RME devices can report BL/Boot Loader image types to IoT FND, but IoT FND cannot upload boot loader images to devices.

Actions Supported and Information Displayed at the Firmware Management Pane

At the Firmware Management pane, you can filter the display by Subnet, PanID or Group when you are in the Devices tab.

For every image in the list, IoT FND displays the information as noted in the table:

AP800 Firmware Upgrade During Zero Touch Deployment

During the PnP bootstrapping, whenever an access point (AP) or router sends the firmware request, FND will need to make the choice as to whether Unified Firmware or Autonomous Firmware is updated on the AP to make it accessible to the Cisco Wireless LAN Controller (WLC) after a firmware upgrade.


Note
Once you set up the DHCP server on a Cisco IOS router, WLC generally handles the software updates for the AP.

Allows you to set the desired firmware that will update an IR829 router during ZTD.

There are two possible firmware options:

  • Option 1: Set the ‘unified’ version (k9w8: the factory-shipped version) as the desired firmware.

  • Option 2 : Set the autonomous firmware as the desired firmware version.

During the ZTD process, the firmware upgrade of an access point (AP) or embedded AP on an IR829 router will upgrade using the firmware version you define as the autonomous firmware.

To define the Autonomous Firmware for an IR829 router:

Procedure

Step 1

Choose CONFIG > DEVICE CONFIGURATION.

Step 2

Select the desired router: Default-ir800 (left-pane).

Step 3

Check the installed firmware version, BEFORE upload. if equal to the latest version, skip firmware upgrade.

Step 4

Before you upload the software to the router, check the image and version:

  • If the router image version is equal to the latest version, skip upgrade.

  • If router image has the latest

Step 5

Select Edit AP Configuration Template tab (right-pane).

Step 6

Enter the following text in the right-pane:

ip dhcp pool embedded-ap-pool
network <router_ip> 255.255.255.0
dns-server <dns_ip>
default-router <router_ip>
option 43 hex f104.0a0a.0a0f (Note: Enter a single WLC IP
address(10.10.10.15) in hex format)
ip address <router_ip> 255.255.255.0
! {Note the symbol in this line is an exclamation point}
service-module wlan-ap 0 bootimage unified

Step 7

Click disk icon (bottom of page) to save the commands in the configuration template.

Image Diff Files for IR809 and IR829

To reduce the file size that transfers across network for IR809 and IR829, you can send a partial image:

  • At the Upload Image page, select type: IOS-IR800.

  • Check box for option: “install patch for IOS and hypervisor from this bundle.”

Gateway Firmware Updates

IC3000 Firmware Updates:

  • At the CONFIG > FIRMWARE UPDATE page, you can add or delete the IC3000 firmware image.


    Note

    Firmware image upload depends on interface speeds. You can set the timeout duration (in minutes) for firmware upload in cgms.properties file using "igma-idle-timeout" key. If you don’t set this duration, then default timeout duration will be 15 minutes.

  • At the Images tab page, expand the Gateway icon and click on IC3000 to see a list of available IC3000 images.

Configuring Firmware Group Settings

This section describes how to add, delete, and configure firmware groups, and includes the following topics:


Note
Upload operations only begin when you click the Resume button.

When you add routers or RMEs to IoT FND, the application sorts the devices into the corresponding default firmware group: default-<router> or default-cgmesh. Use these groups to upload and install firmware images on member devices. Add firmware groups to manage custom sets of devices. You can assign devices to firmware groups manually or in bulk. Before deleting a firmware group, you must move all devices in the group to another group. You cannot delete non-empty groups.

When creating firmware groups note the guidelines:

  • CGRs, IR800s can coexist on a network; however, for firmware management, they cannot belong to the same firmware group.

  • IR500s and other RMEs devices can coexist on a network; however, for firmware management, they cannot belong to the same group.

The Groups tab on the CONFIG > FIRMWARE UPDATE page displays various device metrics.

Figure 8. CONFIG > FIRMWARE UPDATE

Tip
At the Firmware Update page, click the Error/Devices link (not shown) in Firmware Upgrade Page – Viewing Errored Devices to apply a filter.

Working with Router Firmware Images

This section describes how to work with router firmware images in IoT FND.

Installing a Firmware Image

To install an image on devices in a router firmware group:

Procedure

Step 1

Choose CONFIG > FIRMWARE UPDATE.

Step 2

Click the Groups tab.

Step 3

In the Groups pane, select the firmware group.

Note

 
IoT FND recognizes devices as firmware-specific, and uploads the proper image to selected devices.

Step 4

In the Images pane, select a device subgroup (such as IOS-CGR, IOS-WPAN-RF, CDMA) to refine the display to those device types.

This step above is necessary because IoT FND recognizes devices as firmware-specific and ensures the system uploads the proper image to selected devices.

Step 5

At the CONFIG > FIRMWARE UPDATE page, click the Groups tab; and, then Install Image on the Firmware Upgrade tab.

IoT FND sends commands to install the uploaded image and make it operational.

Step 6

Click Yes.

IoT FND starts the installation or reloading process.

Note

 
If you restart IoT FND during the image installation process, IoT FND restarts the firmware installation operations that were running prior to IoT FND going offline.

You can pause or stop the installation operation as described in:

Note

 
The firmware installation operation can time out on some routers. During firmware install, the job scheduler that runs every two hours times out the stuck firmware install jobs that has progressed upto 35%. The default time of the job scheduler of two hours can be modified in the "firmware-install-timeout-schedule-cron-hour" key in the cgms.properties file. Provide values within the range of greater than 0 and less than 24. This job scheduler is applicable only for install at 35%.

Note

 

When a firmware install or image upload operation for routers take extended run time, it can result in prolonged wait times for the other jobs in the queue. You can configure timeout duration for the stuck firmware jobs in the “router-firmware-upload-timeout-minutes” and “router-firmware-install-timeout-minutes” keys in cgms.properties file. The default value is set to 8 hours (480 minutes). The timeout is accounted after the device stops responding and the following error message is displayed.

Adding a Firmware Image to IoT FND

Before you can upload and install a firmware image on a device, add the image file (as a zip archive) to IoT FND. IoT FND stores the image in its database.


Note
Do not unzip the image file. IoT FND unzips the file.

To add a firmware image to IoT FND:

Procedure

Step 1

Choose CONFIG > FIRMWARE UPDATE.

Step 2

Click the Images tab ( CONFIG > FIRMWARE UPDATE > Image).

Step 3

In the Images pane, select ROUTER, ENDPOINT, or GATEWAY and the type of device group.

Step 4

Click the + icon to select an image found to the right of the Firmware Images heading.

Step 5

Click Browse to locate the firmware image. Select the image, then click Add File.

Step 6

Click Upload.

The image appears in the Firmware Images panel ( CONFIG > FIRMWARE UPDATE > Image).

  • To delete an image, click the Delete link shown at far-right of entry. Click Yes to confirm.

    Firmware images with a download in progress (with Yes in the Active Download? column) cannot be deleted.

  • To upload the firmware image to devices in a group, select the group (from Groups listing on CONFIG > FIRMWARE UPDATE page) and then click Upload Image. See Uploading a Firmware Image to a Router Group.

Uploading a Firmware Image to a Router Group

When you upload a firmware image to router firmware group members, IoT FND pushes the image to the group members in the background and tracks the upload progress to ensure that the devices receive the image.

On routers, firmware image upload and installation requires 200 MB of free disk space. IoT FND stores image files in the .../managed/images directory on the router.


Note
If there is not enough disk space on the router for the firmware image, the IoT FND initiates disk cleanup process on the router and removes unused files in the .../managed/images directory that is not currently running or referenced in the before-tunnel-config, before-registration-config, express-setup-config, and factory-config files for IOS CGRs, sequentially, until there is enough disk space to upload the new image.

If there is still not enough space, you must manually delete unused files on the router.

To upload a firmware image to router group members:

Procedure

Step 1

Choose CONFIG > FIRMWARE UPDATE.

Support for Wi-SUN Stack Switch

Starting with Cisco IoT FND 4.8.1 release, you can switch devices from CG-Mesh to Wi-SUN (Wireless and Smart Utility Networks) stack. User with administrative privilege or firmware upgrade permission can only perform this switch operation. During the switching process, a single or multiple PAN nodes are grouped and scheduled for switching devices from CG-Mesh to Wi-SUN stack. Wi-SUN stack supports both unicast and multicast transmissions. For more information on the switching process, refer to Switching Devices from CG-Mesh to Wi-SUN Stack.

Supported Platforms

IoT FND supports the following platforms for switching devices from CG-Mesh to Wi-SUN stack:

  • ITRON30

  • IR510

  • IR530

Prerequisites

  • Firmware version must be 6.2 MR.

  • CGR version must be greater than Cisco IOS 15.9(3)M1.


Note

On successful switching of devices from CG-Mesh to Wi-SUN stack mode, ensure to update the WPAN OFDM/FSK stack mode to Wi-SUN stack. If the WPAN OFDM/FSK is not updated, the node cannot join back the network and will move to Down state in FND.

    Scenarios

    System Validation

    User Action

    Firmware version 6.2 MR.

    Checks if the devices in the selected PAN ID are running firmware version 6.2 MR.

    • If the firmware version is lower than 6.2 MR, then an error message appears.

      Note

       

      Go to the Devices tab, for more information on the devices that are running a lower version.

    • You must upgrade the devices to firmware version 6.2 MR.

    • After upgrading the devices, you must again push new stack mode for the selected PAN ID.

    • If the firmware version is greater than 6.2 MR, then the devices are already in Wi-SUN stack.

    Stack mode configuration.

    Checks if all devices in the selected PAN ID received the stack mode configuration.

    • Some devices in the selected PAN ID fail to receive the configuration.

    • Push stack mode again for the selected PAN ID.

      or

    • Remove the devices that are in Down state from FND and again push stack mode for the remaining devices in the PAN ID.

    • If all the devices in the selected PAN ID received the stack mode configuration, then you can schedule the devices for stack switch operation initiation.

    Scheduling Devices for Wi-SUN Stack Switch

    Note

     

    You can schedule the devices for Wi-SUN stack switch only on successful completion of pushing stack mode configuration to all devices in the selected PAN.

  2. On successful completion of the validation, the stack operation state for the selected PAN ID changes to Stack Mode Push Completed.

Scheduling Devices for Wi-SUN Stack Switch


Note

You can schedule devices for the Wi-SUN stack switching process only on successful completion of pushing devices to stack mode. For more information on pushing devices to Wi-SUN stack mode, see Pushing Devices to Wi-SUN Stack Mode
