Understanding Fabric Software

This document provides detailed information for the Fabric Software feature for Nexus Dashboard Fabric Controller release 12.2.1 or later.

Fabric Software deploys Cisco software images to switches which allows network stability and feature consistency. The benefits of Fabric Software workflows include the following:

  • Comprehensive image management policies allow you to specify a version and patch level for a set of switches

  • Nexus Dashboard Fabric Controller (NDFC) validates compliance for the image policy associated with each switch

  • Image staging, validation, and in-service software upgrade (ISSU) operations are independent, allowing mass upgrades and downgrades, and the ability to perform staging and validation in a single step

    • You can perform the following operations before the maintenance window:

      • Stage image files

        This copies the image files to the bootflash.

      • Validate Network Operating System (NOS) and EPLD compatibility where possible

        This checks if the image is complete, if the image is valid for the individual hardware, and if the upgrade can be non-disruptive.

      • Run pre-upgrade reports

  • The ability to run reports pre/post-upgrade and compare the results

  • The ability to generate snapshots of the configuration pre/post-upgrade

  • The View Details column provides Live log status to monitor each operation

  • Allows you to make use of maintenance mode to minimize the impact of disruptive upgrades, especially for multi-reload upgrade situations

  • Allows you to perform multiple operations on the devices simultaneously. However, you cannot perform multiple operations on the same set of devices at the same time.

  • Upgrade groups allows bulk upgrades and downgrades. Upgrade groups have checks to avoid unnecessary downtime in redundant fabrics in the following cases:

    • All switches of a given role for a fabric will be in the same group

    • Switches that are grouped in odd or even groups:

      • Switches that have even numbers or VPC role of primary

      • Switches that have odd numbers or VPC role of secondary

  • Provides visibility into previous and current upgrade details as well as high level summarization

  • Visibility into current NOS, EPLD and patch consistency at a switch, fabric, and group level

Starting with Nexus Dashboard Fabric Controller release 12.2.1, the Overview tab has changed and displays the images, policies, platforms, release versions, and fabric information.

The Fabric Software UI has the following functional areas:

  • Overview: This displays the images, policies, platforms, release versions, and fabric information.

    • The Images card displays the number of images and the type of packages or patches.

    • The Policies card displays the number of polices, the number and types of platforms, and the release versions and the types of switches.

    • The fabric area displays information about the configured fabrics.

  • Ensure that your user role is network-admin or device-upg-admin.

  • Ensure that there is a fabric, the fabric must have the "Deployment Enabled" flag set, and the switches are managed by the Nexus Dashboard Fabric Controller in this fabric.

  • Ensure you have LAN credential set.

Upgrade or Downgrade a Group of Switches

You have two upgrade methods and one downgrade method:

Upgrading or Downgrading a Group of Switches (Disruptive)

This section describes a disruptive method for upgrading or downgrading a group of switches.

If you are downgrading a group of switches, the process is identical to the process for upgrading a group of switches, except that the target image that you choose will be earlier than the currently installed image. The text for dialogs, fields, buttons, and other controls in the UI specify “upgrade” even though you are downgrading the software.

Downloading an Image from the Software Download Website

This section describes how to download an image from the software download website.

Procedure

Step 1

Go to the Software Download website.

Software Download Website

Step 2

Login with your credentials. You must login to download the software.

Step 3

Navigate to Switches, choose a series and a switch.

Step 4

Depending on the switch model, choose a software type:

  • For Nexus switches:

    • NX-OS EPLD Updates

    • NX-OS Firmware

    • NX-OS Patch Release

    • NX-OS Software Maintenance Upgrades (SMU)

    • NX-OS System Software

  • For Cisco Catalyst switches: IOS XE Software

    For Cisco Catalyst switches, NDFC provides support for software upgrade using CAT9K and CAT9K_LITE image types.

Step 5

Choose the software file you want to download and click the download icon.

Uploading the Image to Nexus Dashboard Fabric Controller

This section describes how to upload the image.


Note

In some cases, you can download an SMU image from the Software Download website wherein multiple RPMs are bundled together as a .tar file, and NDFC allows you to upload this type of bundled .tar file to NDFC. However, NDFC normally does not allow you to upload any other type of bundled .tar file, so if you try to upload a bundled .tar file and you see an error message, use a .zip format instead for the bundle.


Note

If you are about to upload a compacted NX-OS image to the NDFC image repository and another NX-OS image with the same name is currently in the repository, you might overwrite the existing (older) NX-OS image with the newer NX-OS image that you are about to upload. You can avoid overwriting the existing image using the following method:

  1. Upgrade the switches that can use normal NX-OS image first.

  2. Delete the normal NX-OS image from the NDFC repository using the Image Upload screen.

  3. Upload the compact image and upgrade the other set of switches.
Procedure

Step 1

In the Fabric Software window, choose Images.

Step 2

From the Actions drop-down list, select Upload.

Step 3

In the Upload Image dialog box, either upload the file or import from SCP.

Note that uploading an image to SCP or SFTP server from a non-Unix based device is not supported.

Step 4

Click Verify.

Creating the Image Policies

This section describes how to create the image policies.

Procedure

Depending on the switch type, not all fields in the Create Fabric Software Policy dialog box are available to all the devices.

Step 4

Click Save.

Creating and Attaching a Group to the Switches

This section describes how to create and attach a group to switches. Grouping allows you to track upgrades for a set of switches. You can create several groups and select a switch regardless of the group, role, or type of switch.

We recommend that you create upgrade groups based on the switch roles. For example, if a fabric has multiple switches with different roles, such as Leaf, Spine, Border, and more, creating groups based on different roles is recommended. This clearly separates roles and responsibilities during switch image management operations. Switches with different roles perform critical functionality and respond differently based on the control plane, data plane, and system-level convergence. For example, a user with the admin role can create multiple groups as follows:

  • Group-Leaf-Even for Leaf switches that have even numbers or VPC role of primary

  • Group-Leaf-Odd for Leaf switches that have odd numbers or VPC role of secondary

Typically, Spine and Border devices are limited to fabric, while the role of the Leaf is the most common one. Therefore, users with the admin role can upgrade individual Spines followed by Individual Borders, or create different groups for Spines and Borders. Users with the admin role can still leverage groups to divide the Leaf role switches and perform bulk actions.

Procedure

Step 1

In the Fabric Software window, choose Devices.

Step 2

In the Devices window, place a checkmark in the checkbox for the devices you want to group.

Step 3

From the Actions drop-down list, select Modify Groups.

This section describes how to create and attach a group to switches. Grouping allows you to track upgrades for a set of switches. You can create several groups and select a switch regardless of the group, role, or type of switch.

We recommend that you create upgrade groups based on the switch roles. For example, if a fabric has multiple switches with different roles, such as Leaf, Spine, Border, and more, creating groups based on different roles is recommended. This clearly separates roles and responsibilities during switch image management operations. Switches with different roles perform critical functionality and respond differently based on the control plane, data plane, and system-level convergence. For example, a user with the admin role can create multiple groups as follows:

  • Group-Leaf-Even for Leaf switches that have even numbers or VPC role of primary

  • Group-Leaf-Odd for Leaf switches that have odd numbers or VPC role of secondary

Typically, Spine and Border devices are limited to fabric, while the role of the Leaf is the most common one. Therefore, users with the admin role can upgrade individual Spines followed by Individual Borders, or create different groups for Spines and Borders. Users with the admin role can still leverage groups to divide the Leaf role switches and perform bulk actions.

Note

This feature applies only for LAN fabrics.

Preparing a Fabric Image Policy

This section describes how to prepare a software image policy that can be used at the fabric level.

Procedure

Step 1

In the Fabric Software window, verify that the Overview tab is selected.

See Understanding Fabric Software for more information on the Overview tab and the other tabs in the Fabric Software window.

Step 2

In the list of fabrics shown in the Overview page, locate the fabric where you want to prepare a software image policy that will be used for that fabric.

Step 3

In the Status column, click Prepare in the row for the fabric where you want to prepare a software image policy.

The Prepare - <fabric> window appears.

Step 4

In the Prepare - <fabric> window, make the appropriate configurations for this fabric-level image policy.

  1. Review the types of devices listed in the Platforms area.

    The list will consist of device types that are detected in this fabric. Use this list to verify that the software policy that you select in the next step aligns with the type of devices that you have in this fabric.

    For example, if you see CAT9K,N9K listed in the Platforms area, when you select the policy in the next step, you would want to verify that any policy that you select aligns with either Catalyst 9000 or Nexus 9000 series switches.

  2. Click the radio button to either Attach Policy or Detach Policy.

    • If you select Detach Policy, click Detach to detach the fabric-level image policy from these switches in this fabric.

    • If you select Attach Policy, proceed with these instructions to attach an existing image policy or to create a new one.

  3. In the Policy field, attach an existing image policy or create a new one.

    • If you already have fabric-level image policies created and you want to use one of those existing image policies, scroll through the list of image policies and select the one that you want to use. Go to 4.d.

    • If you do not have any fabric-level image policies created yet, or if you do not want to use one of the existing image policies for any reason, click +Create Policy.

      The Create New Image Management Policy window appears.

      1. In the Create New Image Management Policy window, enter a unique name for the fabric-level image policy in the Policy Name field or leave the automatically-generated policy name as-is, if desired.

      2. Enter a description for the new fabric-level image policy in the Policy Description field, if necessary.

      3. In the Rules area, click +Add Row.

      4. Enter the necessary information in the Rules area to configure this new fabric-level image policy.

        • Platform: Select the types of switches in the fabric that will use this new fabric-level image policy.

        • Role: Select the roles for the switches in the fabric that will use this new fabric-level image policy.

        • Use one of the following options to be used with this new fabric-level image policy:

          • Image: Select the software image that will be used with this new fabric-level image policy.

          • Install Packages: Select the installation packages that will be used with this new fabric-level image policy.

          • EPLD: Select the electronic programmable logic device (EPLD) image that will be used with this new fabric-level image policy.

        • Uninstall Packages: Check the box to uninstall packages from the switches in the fabric as part of this new fabric-level image policy.

      5. Click the checkbox in the row to complete the configuration for this image policy rule.

      6. Repeat these steps to configure a new set of rules for this fabric-wide image policy, if necessary.

        For example, you might configure a new set of rules with a different option in the Platform field selected to configure a new set of rules for other types of switches in the fabric, or with a different option in the Role area selected to configure a new set of rules for switches with a different role in the fabric.

      7. Click Save when you have configured all the necessary rules in the fabric-level image policy.

        You are returned to the Prepare - <fabric> window, with this new fabric-level image policy automatically selected in the Policy field.

  4. Determine when you want to stage the fabric-level image policy.

    • Leave the Stage Now option unselected to stage the fabric-level image policy at a later date.

      Staging the fabric-level image policy later allows you to stage the images in the fabric to be used later (for example, by copying the images onto the switch bootflash) so that you can upgrade a subset of the devices later that match the policy.

    • Click the Stage Now option to enable this option.

      The fabric-level image policy will stage after you click Attach in the next step.

  5. Click Attach.

The image policy is now attached to this fabric, and is displayed in the Policy column in the Overview page.

Step 5

Make additional configurations for each fabric, if necessary, based on the status shown in the Status column:

  • None: No fabric-level image policy has been configured for this fabric.

  • In-Sync: The current image versions on each switch in the fabric is in-sync with the expected image versions. No further configurations are needed for the fabric-level image policy for this fabric.

  • Out-of-Sync: The current image versions on one or more switches in the fabric is out-of-sync with the expected image versions. Click the Out-of-Sync text in the Status column to bring up a slide-in pane that shows which switches in the fabric are out-of-sync with the expected image versions. See Recalculating Compliance for more information.

  • Prepare: Click to prepare a software image policy that can be used at the fabric level, as described in this topic.

  • Update plan: The system is ready to apply software updates to the appropriate switches in the fabric. Click Update plan to bring up the Software Update Plan for the fabric. See Installing or Upgrading Software on Devices in a Fabric for more information.

Once you have prepared a software image policy that will be used for a fabric, you cannot then delete or edit that policy directly. However, you can delete uploaded images, even if the ref count is greater than 0.

If uploaded images are used in a software image policy but you have not attached that software image policy to any devices yet, then you can delete those software image policies along with the selected images. However, if you created multiple software image policies using one image and you attached one of those policies to devices in a fabric, then you cannot delete the image and you cannot delete any of the other software image policies that use that image, even if those software image policies aren't attached to any devices in the fabric yet.

Changing Number of Concurrent Switches for Staging/Validating/Updating

As you go through the procedures in Installing or Upgrading Software on Devices in a Fabric, there are points during the staging/validating or updating processes where you might be taking actions on a group of switches concurrently. Following are the default values for the number of switches that are grouped together when you are taking an action on a group of switches concurrently:

  • Staging/validating: Default number of switches is 10

  • Updating: Default number of switches is 20

Follow these procedures if you want to change these default values.

Procedure

Step 1

Navigate to:

Admin > System Settings > Admin

Step 2

Modify the values in the following fields, if necessary:

  • Image update thread pool size: The number of switches that can be updated concurrently. Default value is 20. Valid range is 10-200.

  • Image stage/validate thread pool size: The number of switches that can be staged and validated concurrently. Default value is 10. Valid range is 5-200.

Step 3

Click Save when you have completed any configuration changes on this page.

Installing or Upgrading Software on Devices in a Fabric

This section describes how to install or upgrade software on the devices in a fabric using a fabric-level image policy.

Procedure

Step 1

In the Fabric Software window, verify that the Overview tab is selected.

Step 2

In the list of fabrics shown in the Overview page, locate the fabric where you want to install or upgrade software on the devices in that fabric.

Step 3

In the row for a fabric, select Update plan in the Status column to install or update the software on the devices in that fabric.

The Software Update Plan window appears.

Step 4

Determine if you want to automatically assign groups.

To automatically assign groups, click Actions > Auto-Assign Groups.

You can automatically assign groups based on the following criteria:

  • Role Based: All switches of a given role for a fabric in the same group

  • Even Odd: Switches that are grouped in odd or even groups:

    • Switches that have even numbers or vPC role of primary

    • Switches that have odd numbers or vPC role of secondary

    NDFC uses the following calculations to balance the number of switches in the even and odd groups as much as possible:

    1. NDFC will first divide the switches by role between the even and odd groups; this is done to reduce the likelihood of having most or all of one type of switch in only one of the two groups.

    2. NDFC will then alternate switch assignments between the even and odd groups, where the first switch of one type goes into the even group, the second switch of that same type goes into the odd group, and so on.

Step 5

Review the information provided in the Software Summary area.

  • Fabric: The name of the fabric where you will be installing or upgrading software on the devices in that fabric.

  • Update Plan Status: The status of the update plan.

  • Update Groups: The number of groups that will be part of this software update in this fabric.

  • Devices to be Updated: The number of devices in this fabric that will be updated.

  • Policy: Click the link to open a side panel showing the fabric level policy details.

Step 6

Review the general information provided in the switch group area.

  • The first area shows whether the update has yet to start and any warnings about the update. Click Warnings to bring in a side panel with more information on the warnings.

  • Switches: Shows the number of switches in this switch group.

  • Update Status: Shows the status of the update.

  • Install Start Time: Shows the time when the update installation started.

  • Install End Time: Shows the time when the update installation ended.

Step 7

Review the more detailed information provided in the switch group area.

Click the down arrow next to the switch group name to display more detailed information on that switch group.

Field

Description

Mode

The mode for the switch in the switch group.

vPC Role

The vPC role of the switch in the switch group, if applicable.

vPC Peer

The vPC peer of the switch in the switch group, if applicable.

Policy

The update policy associated with this switch in the switch group. Click the update policy for additional information.

Last Upgrade Action

The last upgrade action for this switch in the switch group.

Step 8

Determine if you want to make changes to the switches in the update group.

For each of the actions listed below, you can click the box next to single switch in the update group or click the box next to Switch to select all the switches in the update group. The following options are then displayed above the update group:

  • Remove from Update Group: Click to remove the selected switch(es) from the update group.

  • Create New Update Group: Click to create a new update group with the selected switch(es).

  • Move to Update Group: Click to move the selected switch(es) to a different update group.

Step 9

To upgrade the switches in an update group, perform the following steps in that group's area in the Software Update Plan window:

Note

 

The default number of number of switches that can be staged and validated concurrently is 10, and the number of switches that can be updated concurrently is 20. To change those default values, see Changing Number of Concurrent Switches for Staging/Validating/Updating.

  1. First click Stage/Distribute to stage and validate the update.

    Click View Logs to view the actions that take place on the NX-OS switches as they relate to NDFC.

  2. Then click Install Update to perform the software update on the switches in this update group.

    Install Update allows you to trigger a software upgrade for all the switches in that update group.

    A confirmation dialog appears that provides an estimated timeframe for the installation process based on the number of switches in the update group. Note that the estimated timeframe might change based on a number of variables:

    • The number of switches that are in an update group. By default, updates are performed concurrently on 20 switches at a time, so if you have 40 switches in an update group, updates are first performed on the first batch of 20 switches, and then a second pass is performed on the second batch of 20 switches.

    • Advanced options that are described in the next step, which may change the estimated timeframe, depending on the advanced option.

  3. (Optional) In the Install Update confirmation dialog, click the Show Advanced Options arrow to make the advanced selections for the installation, if necessary.

    • In the Execution Paradigm field, select a Serial or Parallel execution:

      • Serial: Switches are updated one at a time, serially, where the update process must fully complete on one switch before it begins on the next switch in the update group.

      • Parallel: Switches are updated all at one time, depending on the number of switches that can be updated concurrently. For example, if you have 40 switches in the update group but 20 switches are updated at a time concurrently, then a Parallel setting will result in the first set of 20 switches going through the update process, all at one time, and then the second set of 20 switches going through the same concurrent update process after the update process has completed for the first set.

    • In the On Failure field, determine if you want the installation to Continue or to Pause if there is a failure that occurs during the update. A failure might occur for a number of reasons, such as a switch failing to come back online or a failure to successfully establish an ssh session between NDFC and the switch.

      The actions taken with this setting may also be affected by settings in other areas.

      For example, assume that you have Pause as the setting for this field, and you have Serial as the setting in the Execution Paradigm field. If a set of 20 switches in an update group are going through a serial update and an issue arises with the sixth switch in the set, the update will pause at that sixth switch's update process and will not proceed with the update process for the remaining 14 switches in the set until you manually begin the update process again.

      However, if you have Parallel as the setting in the Execution Paradigm field and there is an issue with the sixth switch in a set in the update group, the update process will complete for the other 14 switches in the set that are being updated concurrently, and the update process will pause before moving to the update processs for the next set of switches in the update group.

    • In the Snapshot field, choose either the Snapshot or No Snapshot option.

      Note that the snapshot option is essentially a reporting mechanism to compare the state of the system before and after an upgrade; the snapshot option in this case is not used to create a checkpoint (snapshot) of the system. See Snapshots for more information about this option.

    • Check the box next to Maintenance Mode if you want to enable this option.

      Maintenance mode, along with normal mode, are part of Graceful Insertion and Removal, or GIR. When the Maintenance Mode option is enabled, NDFC will place the switches in the update group in the maintenance mode during the update process, where all configured Layer 3 control-plane protocols are isolated from the network, and will return the switches to normal mode after the update process is completed. Refer to the Configuring Graceful Insertion and Removal for more information on GIR.

    • Make the proper selection in the Force Disruptive field, if necessary.

      When you click Stage/Distribute earlier in these procedures, NDFC will determine if the switches in the update group are set with disruptive or non-disruptive upgrade settings.

      • If all of the switches are shown as non-disruptive in the initial staging point of the process, then the default value for this field will be for the box next to the Force Disruptive field as unchecked (not enabled).

      • However, if any of the switches are shown as disruptive in the initial staging point of the process, then the default value for this field will be for the box next to the Force Disruptive field as checked (enabled) for all of the switches in this update group.

      Refer to the Understanding In-Service Software Upgrades for more information about this option.

Recalculating Compliance

This section describes how to recalculate compliance on devices in a fabric where software was installed or upgraded using a fabric-level image policy.

The Recalculate Compliance option checks if the versions on the switch and the policy are same. You might want to recalculate compliance when the information on the Overview page does not correctly reflect the expected status for the devices in a fabric or to change the Status from Out-of-Sync to In-Sync. If you made a change directly on the switch CLI, you might also use the Recalculate Compliance option so that the system fetches those updates from the switch and compares them with those in the fabric policy rules.

Procedure

Step 1

In the Fabric Software window, verify that the Overview tab is selected.

Step 2

In the list of fabrics shown in the Overview page, locate the fabric where you want to recalculate compliance on the devices in that fabric.

Step 3

In the row for that fabric, click the ellipsis at the end of that row (…), then select Recalculate Compliance.

The status provided in the Status column might get updated to In-Sync or Out-of-Sync, based on a comparison between the switch CLI and the fabric policy. Click on the status entry to show additional in-sync or out-of-sync details.
