In Nexus 9000 switches, DNF (Dandified YUM) is the package manager used to manage modular software components (RPMs) within the NX-OS environment. Beginning with NX-OS Release 10.1(x), DNF replaced YUM as the primary tool for the Optionality feature, allowing you to install, upgrade, or remove specific features (such as Layer 3, BGP, or OSPF) without performing a full system binary upgrade or reloading the switch.

Note

DNF commands do not support CTRL+C. Install commands do support CTRL+C. If DNF commands are aborted using CTRL+C, manual cleanup must be performed using /isan/bin/patching_utils.py --unlock .

Package operations with DNF commands

This section describes how to perform package operations using the DNF commands.

This section describes how to perform package operations using the DNF commands:

Note

DNF commands are accessed only from the BASH shell on the box and they are not allowed from the NX-OS VSH terminal.

Make sure that as a sudo user, you have access to the super user privileges.

Find the base version RPM of the image

The base RPM version is the pre-installed RPM that is archived in the system image.

Use the ls /rpms command to find the base version RPM of the image.

switch# ls /rpms

Check the list of the installed RPMs

Use the dnf list installed command to query the feature and third party RPMs and grep a specific RPM.

Here is an example for feature RPMs.

bash-4.2# dnf list installed | grep lib32_n9000

Support for DNF groups

The DNF group is a feature that

simplifies the management of the packages for the administrators
provides greater flexibility, and
allows administrators to manage collections of packages as logical groups.

The support for DNF groups is part of the package management.

The administrators can group a list of packages (RPMs) into a logical group and they can perform various operations. The group commands that DNFsupports include

grouplist
groupinfo
groupinstall
groupremove , and
groupupdate.

The DNF groups can be broadly classified as Layer 2, Layer 3, routing, and management.

Grouplist command for listing available package groups

In Linux, number of packages are bundled to particular group. Instead of installing individual packages with dnf, you can install particular group that will install all the related packages that belongs to the group. For example to list all the available groups, use the dnf grouplist command:

List all available package groups in Linux using the dnfgrouplist command.

bash-4.4# dnf grouplist

Available Groups:
   management
   routing
   L2
   L3
bash-4.4#

Groupmembers command for displaying package group contents

Display the description and the contents of a package group using the dnf groupinfo command.

The command lists out the feature members of the group.

bash-4.4# dnf groupinfo l2

Group: L2
 Mandatory Packages:
   lacp
   lldp
   svi
   vtp
bash-4.4#

Groupinstall command for install and upgrade of member RPM

This command is for both install and upgrade of the members RPM. If the member is not installed, it installs the highest version available. If the member is already installed and higher RPM is available, it upgrades that member.

bash-4.4# dnf groupinstall l3

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.
