Optionality in Cisco NX-OS Software

This chapter describes optionality in Cisco NX-OS software.

Optionality in Cisco NX-OS Software

Beginning with Cisco NXOS Release 9.2(1), Cisco NX-OS software image supports modular package management. Cisco NX-OS software now provides flexibility to add, remove, and upgrade the features selectively without changing the base NX-OS software.

The advantages for using modular Cisco NX-OS software are:

  • Lean NX-OS software

  • Asynchronous delivery of the features and the fixes: Quick fixes are provided that are independent of the releases, including new features.

  • Reduced footprint of binaries and libraries at run time

Cisco NX-OS software is provisioned to boot the NX-OS software in two modes as described in the following illustration:

  • Base NX-OS mode

  • Full NX-OS mode

Figure 1. Optionality in Cisco NX-OS Software

  • Base NX-OS mode contains:

    • Upgradable mandatory packages

    • Patchable packages

  • Full NX-OS mode contains:

    • Upgradable optional packages

    • Upgradable mandatory packages

    • Patchable packages


Note

The default mode is full NX-OS mode.

In base NX-OS mode, basic Layer 2 and Layer 3 features are available. All dynamic routing features (for example, BGP, OSPF, EIGRP, RIP, and ISIS ) and other optional feature RPMs are not available by default. You have to install the optional feature RPMs on top of the base image.

In full NX-OS mode, all feature RPMs are installed during boot time when Ethernet plugin is activated by the plugin manager. There is no change in the user behavior as compared to the previous releases.

Using Modular Packages

The Cisco NX-OS software image is traditionally constructed with the packaging that forms a Cisco Linux distribution. It makes upgrading certain packages difficult as each package is large in size.

This section describes a new package management for the Cisco NX-OS software image. Beginning with Cisco NX-OS Release 9.2(1), some NXOS features are considered as optional, for example, BGP, OSPF, VXLAN, MPLS, Segment Routing.

Each modular package has the following important characteristics:

  • Upgrade functionality: The modular packages can be independently upgraded. The modular packages should be used from the same release as performing upgrades on these packages across multiple releases is not supported.

  • Optionality: The modular packages are optional, for example, these packages can be removed or uninstalled at run time. The removal of the modular packages does not affect bringing-up the system and it does not affect any other functionality of the switches.


Note

All APIs exported by the modular package should be used only after the installation of the feature.

RPM and YUM

RPM (Red Hat Package Manager) is the package management system used for packaging in the Linux Standard Base (LSB). The RPM command options are grouped into three subgroups for:

  • Querying and verifying packages

  • Installing, upgrading, and removing packages

  • Performing miscellaneous functions

rpm is the command name for the main command that is used with RPM, whereas .rpm is the extension that is used for the RPM files.

YUM (Yellowdog Updater, Modified) is an open source command-line tool for RPM based Linux systems. It allows users and system administrators to easily install, update, remove, or search software packages on the systems. YUM adds the automatic updates and the package management, including dependency management, to the RPM systems. In addition to understanding the installed packages on a system, YUM works with the repositories that are collections of the packages and they are typically accessible over a network connection.

Booting the NX-OS Image in Base or Full Mode

You can now boot the NX-OS image in base or full mode. The full boot mode installs the complete NX-OS software which is similar to the software of the previous releases. This is the default boot mode. The base boot mode has no optional RPMs installed.

To use the command line option, see the following steps:

  • Use the install reset nxos base option to install the NX-OS image in the base boot mode using the VSH prompt. After reload, the switch is in the base mode with no optional packages installed.

  • Use the install reset nxos full option to install the NX-OS image in the full boot mode using the VSH prompt. After reload, the switch is in the full mode with the optional packages automatically installed.

For more information, see Using Install CLIs for Feature RPM Operation section.

Information About RPMs

RPMs can be upgraded or downgraded to a new software version using NXOS install commands or by using YUM commands. An upgradable RPM can be optional or mandatory.

See the following sections for more information about optional and mandatory RPMs.

Format of the RPM

The general format of a RPM is <name>-<version>-<release>.<arch>.rpm. The same format is followed for NXOS feature RPMS.

  • Name: package name, for example, BGP

  • Version in <x.y.x.b> format: <major.minor.patch.build_number>, for example, 2.0.1.0

  • Release: The branch from which the RPM is created, for example, 9.2.1

  • Arch: The architecture type of the RPM, for example, lib32_n9000

See the following table for more information on the naming convention, for example, fex-2.0.0.0-9.2.1.lib32_n9000.rpm:

Table 1. RPM Naming Convention

RPM Naming Convention

Example: fex-2.0.0.0-9.2.1.lib32_n9000.rpm

Description

fex

Indicates the name of the component.

2

Indicates that the RPM is not backward compatible. Configuration loss takes place during an upgrade.

0

Indicates the incremental API changes/CLI changes/Schema changes with backward compatibility. It is applicable to the new features on top of the existing capabilities. No configuration is lost during an upgrade.

0

Indicates a bug fix without any functionality change. No configuration is lost during an upgrade.

0

This number tracks how many times the component has changed during the development cycle of a release. This value will be 0 for all the release images.

9.2.1

Indicates the release number or the distribution version for the RPM. It aligns to the NVR format. Since the feature RPM is only applicable to a NXOS release, this field has NXOS release version number present.

lib32_n9000

Indicates the architecture type of the RPM.

Optional RPMs and Their Associated Features

The optional RPMs are the RPMs that can be installed to enable the features without affecting the native NXOS behavior or they can be removed using the install deactivate command from the switch.

Optional RPMs, for example, EIGRP are not a part of the base software. They can be added, upgraded, and removed as required using either yum or install CLI commands from the switch.

See the following list of the optional RPMs and their associated features:

Guidelines for NX-OS Feature RPM Installation

See the following NX-OS system RPM repositories that are present in the Cisco NX-OS Series switches for the RPM management.


Note

Avoid manually copying the RPMs to system repositories. Instead use the install or YUM commands.
Table 3. RPM Repositories That Are Present in the Switches

Repository Name

Repository Path

Description

groups-repo

/rpms

Part of the bundled NX-OS image. It is used to keep all the RPMs that are bundled as part of the NX-OS image. All RPMs based in this repository are known as base RPMs.

localdb

/bootflash/.rpmstore/patching/localrepo

Used for RPM persistency. When a user adds a NX-OS feature RPM as part of install add command, the RPM is copied to this location and it is persisted during the reloads. User has the responsibility to clean the repository.

To add a RPM to this repository, use install add command.

To remove a RPM from this repository, use install remove command.

YUM commands can be used to populate the repository too.

The maximum space for the repository is 200Mb along with the patching repository for Cisco Nexus 9000 Series switches except Cisco Nexus 3000 Series switches. For Cisco Nexus 3000 Series switches, the maximum space for the repository is 20 Mb only.

patching

/bootflash/.rpmstore/patching/patchrepo

Used for RPM persistency. When a user adds a NX-OS patch RPM to the switch, the patch RPM is copied to this repository.

thirdparty

/bootflash/.rpmstore/thirdparty

Used for RPM persistency when a user adds a third party RPM.

The groups-repo and localdb repositories hold the NX-OS feature RPMs that should be installed during the system boot or during activation. YUM commands or install command can be used for the installation or the removal of these RPMs.

The following rules are applied to the feature RPM installation procedure during boot or install time:

  • Only RPMs with the same NX-OS release number should be selected for the installation.

  • Base RPMs cannot be added to the localdb repository.

Guidelines for Third-Party RPM Installation

Currently, any third-party package that is not provided by Cisco is allowed to be installed on the device, even when it is not signed by Cisco.

Starting with release 10.1(x) any third-party package that is not signed by Cisco is not allowed to be installed on the device. However, if you wish to bypass this and install the software, you can configure the device to enable the third-party software installation. The configuration will persist as a normal configuration and can be verified by using the running-config command. Following this configuration, you can install any third-party software with the known risks.

Using Install CLIs for Feature or Third-Party RPM Operation

See the following reference table for using install CLIs for the feature RPM operations:

Table 4. Reference for Install CLIs for the Feature RPM Operations

CLI

Description

install reset

This operation removes all the patches, persisted configurations, upgraded packages, third-party installed packages, unsaved configurations, and reloads the switch's previous mode (Full/Base) with the default packages.

The install reset command also performs write erase operation. The following message is displayed at the prompt: 


switch(config)# install reset 
======================================================
WARNING!!This operation will remove all pactches, upgraded packages,
persisted etc configs, third party packages installed,
startup configuration(write erase) and
reload the switch with default packages.
=======================================================
Do you want to proceed with reset operation? (y/n)? [n]

install reset nxos base

This operation installs NXOS in base mode by removing all patches, upgraded packages, persisted etc configurations, third-party packages installed, startup configuration (write erase), and reloads the switch with the default packages.

install reset nxos full

This operation installs NXOS with full mode by removing all patches, upgraded packages, persisted etc configs, third-party packages installed, startup configuration (write erase), and reloads the switch with the default packages (with mandatory and optional RPMs).

install add <>

Adds an RPM file to the respective repository and updates the repository (patch/feature/third-party ).

install activate <rpm name>

Installs an RPM that is present in the repository.

install commit <rpm name>

Used for the patch RPMs. Makes the patch persist during the reload.

install deactivate <rpm name>

Un-installs an RPM.

Beginning with Cisco NX-OS Release 10.1(1), when you use this command to deactivate RPMs, the options to either downgrade to the base version of RPM or to uninstall RPM appear. You can select the option that you desire and the operation will proceed.

install remove <rpm name>

Removes an RPM file from the repository and updates the repository.

sh install active

Displays the list of the installed RPMs in the system apart from base rootfs RPMs. (features/patch/third-party).

sh install inactive

Displays the list of the RPMs that are present in the repository but they are not installed.

sh install packages

Lists all the RPMs that are installed including rootfs RPMs.

[no] system software allow third-party

Beginning with Cisco NX-OS Release 10.1(1) the third-party RPM installations are not allowed to be installed on the device by default. This command bypasses this restriction and configures the device to enable the third-party software installation.

The following command shows the error message when you activate third-party RPM without applying the third-party configuration:

switch(config)# install activate pbwMonitor-1.0-1.5.0.x86_64.rpm

Install operation 193 failed because package is not signed by Cisco.Enable TPS installation using 'system software allow third-party' CLI at Tue Nov 17 04:23:10 2020

The following command shows activating third-party RPM installations after applying the configuration: 

switch(config)# system software allow third-party 
switch(config)# 2020 Nov 17 04:25:41 switch %$ VDC-1 %$  %USER-2-SYSTEM_MSG: <<%PATCH-INSTALLER-2-TPS_FEATURE_ENABLED>> User has enabled TPS installation - patch_installer

switch(config)# install activate pbwMonitor-1.0-1.5.0.x86_64.rpm
[####################] 100%
Install operation 194 completed successfully at Tue Nov 17 04:25:58 2020

The following command shows disabling the third-party configuration:

switch(config)# no system software allow third-party 
switch(config)# 2020 Nov 17 04:27:17 switch %$ VDC-1 %$  %USER-2-SYSTEM_MSG: <<%PATCH-INSTALLER-2-TPS_FEATURE_DISABLED>> User has disabled TPS installation - patch_installer

Note

If you are using ISSU or upgrading to Cisco NX-OS Release 10.1.1 release from an earlier version, you must manually apply the third-party configuration within the first 30 minutes after the upgrade to ensure the third-party RPMs get installed.

Information About YUM Commands

See the following sections for more information about YUM commands.


Note

YUM commands do not support ctrl+c. Install commands do support ctrl+c. If YUM commands are aborted using ctrl+c, manual cleanup must be performed using "/isan/bin/patching_utils.py --unlock".

Performing Package Operations Using the YUM Commands

See the following sections for performing package operations using the YUM commands:


Note

YUM commands are accessed only from the BASH shell on the box and they are not allowed from the NXOS VSH terminal.


Note

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

Finding the Base Version RPM of the Image

Use the ls /rpms command to find the base version RPM of the image. The base RPM version is the pre-installed RPM that is archived in the system image.

Support for YUM Groups

The support for YUM groups is part of the package management. It simplifies the management of the packages for the administrators and it provides greater flexibility.

The administrators can group a list of packages (RPMs) into a logical group and they can perform various operations. YUM supports the following group commands:

  • grouplist

  • groupinfo

  • groupinstall

  • groupremove

  • groupupdate

YUM groups can be broadly classified as L2, L3, routing, and management.

Using the grouplist Command

In Linux, number of packages are bundled to particular group. Instead of installing individual packages with yum, 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 yum grouplist command: 


 
bash-4.2# sudo yum grouplist

SUMMARY STEPS

  1. yum install vsftpd
  2. systemctl start vsftpd
  3. systemctl status vsftpd
  4. firewall-cmd --zone=public --permanent --add-port=21/tcp
  5. firewall-cmd --zone=public --permanent --add-service=ftp
  6. firewall-cmd --reload
  7. wget ftp:// <ip of FTP server> /test.txt

DETAILED STEPS

  Command or Action Purpose

Step 1

yum install vsftpd

Installs vsftpd, an FTP server.

Step 2

systemctl start vsftpd

Starts the FTP Server.

Step 3

systemctl status vsftpd

Checks the status of the FTP Server.

Step 4

firewall-cmd --zone=public --permanent --add-port=21/tcp

Allows access to the FTP services from the external systems and opens port 21.

Step 5

firewall-cmd --zone=public --permanent --add-service=ftp

Adds the FTP service.

Step 6

firewall-cmd --reload

Reloads the server.

Step 7

wget ftp:// <ip of FTP server> /test.txt

Hosts a file in the FTP server (for example, test.txt) and attempts Wget of that file.

Note

 

Note that /var/ftp/ is the default home directory of the FTP server.

Creating a Local FTP YUM Repository

Complete the following steps to synchronize the external repository RPMs to the FTP server and create a local FTP YUM repository:

SUMMARY STEPS

  1. cat /etc/yum.repos.d/local.repo
  2. bash-4.3#yum repolist
  3. nohup reposync -r <repo-name mentioned in the local.repo> -p <directory path to sync>&
  4. tail -f nouhup.out

DETAILED STEPS

  Command or Action Purpose

Step 1

cat /etc/yum.repos.d/local.repo

Example:

bash-4.3#cat /etc/yum.repos.d/local.repo 

[localrepo]
name=localrepo
baseurl=
https://devhub.cisco.com/artifactory/open-nxos/7.0-3-I2-1/x86_64/
enabled=1
gpgcheck=0
sslverify=0

Creates a repository file under /etc/yum.repos.d/ , for example, creates local.repo repository and adds the base URL.

Step 2

bash-4.3#yum repolist

Example:

bash-4.3# yum repolist 
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
* base: mirror.dhakacom.com
* extras: mirror.dhakacom.com
* updates: mirror.dhakacom.com
repo id repo name status
base/7/x86_64 CentOS-7 - Base 9,911
extras/7/x86_64 CentOS-7 - Extras 313
localrepo localrepo 687
updates/7/x86_64 CentOS-7 - Updates 711
repolist: 11,622

Checks the reachability of the repository.

Step 3

nohup reposync -r <repo-name mentioned in the local.repo> -p <directory path to sync>&

Example:

nohup reposync -r localrepo -p /var/ftp/ &

This command creates a directory with the name local.repo inside /var/ftp/ and downloads all the packages from devhub.cisco.com to the directory.

Synchronizes all the packages from the external repository to the FTP server home directory.

Step 4

tail -f nouhup.out

Checks the status of the synchronization.

Configuring a Switch to Reach an FTP Server

Complete the following steps to configure a switch to reach an FTP server:

SUMMARY STEPS

  1. run bash sudo su
  2. ip netns exec management ping <ip_address>
  3. cat /etc/yum/repos.d/ftp.repo
  4. ip netns exec management bash
  5. yum repolist
  6. yum list available

DETAILED STEPS

  Command or Action Purpose

Step 1

run bash sudo su

Logs in as a sudo user.

Step 2

ip netns exec management ping <ip_address>

Checks the reachability of the FTP server address from the switch using the ping command.

Step 3

cat /etc/yum/repos.d/ftp.repo

Example:

bash-4.3# cat /etc/yum/repos.d/ftp.repo
[ftp]
name=ftp
baseurl=ftp://10.232.44.34/localrepo/
enabled=1
gpgcheck=0
sslverify=0

Creates a repository file on the switch with the FTP server address as the URL.

Step 4

ip netns exec management bash

Uses the Bash shell prompt.

Step 5

yum repolist

Example:

bash-4.3# yum repolist
Loaded plugins: downloadonly, importpubkey, localrpmDB, patchaction, patching,
: protect-packages
groups-repo | 1.1 kB 00:00 ...
localdb | 951 B 00:00 ...
patching | 951 B 00:00 ...
thirdparty | 951 B 00:00 ...
thirdparty/primary | 758 B 00:00 ...
thirdparty 1/1
repo id repo name status
groups-repo Groups-RPM Database 37
localdb Local RPM Database 0
patching Patch-RPM Database 0
thirdparty Thirdparty RPM Database 1
ftp ftp 686
repolist: 724

Checks the reachability of newly created repository.

Step 6

yum list available

Lists the available packages in the new repository.

Creating User Roles for Install Operation

The install command is only available to the users of admin role. The install command can be available to a user by RBAC. See Guidelines and Limitations for User Accounts and RBAC for the same in the Cisco Nexus 3600 NX-OS Security Configuration Guide.

Compacting Cisco NX-OS Software Images

Cisco NX-OS software image compaction reduces the size of the image file before completing a copy request. Use SCP, HTTP, or HTTPS as the source and bootflash or USB as the destination. The following example uses SCP and bootflash: 

switch# copy scp://user@scpserver.cisco.com//download/nxos64.10.1.1.bin 
bootflash:nxos64.10.1.1.bin compact vrf management use-kstack

user1@10.65.42.196's password:
nxos64.10.1.1.bin 100% 1501MB 8.4MB/s 02:58
Copy complete, now saving to disk (please wait)...
Copy complete.

The compact keyword compacts the NX-OS image before copying the file to the supervisor module.


Note

Software image compaction is only supported on SCP, HTTP, or HTTPS. If you attempt compaction with any other protocol, the system returns the following error: 

Compact option is allowed only with source as scp/http/https and destination
as bootflash or usb

Note

Compacted images are not supported with LXC boot mode.
