Deploying Cisco Nexus Data Broker in Embedded Mode

This chapter contains details of procedures for deploying Cisco Nexus Data Broker on Nexus series switches.

Before your proceed with the upgrade/ install procedures in this chapter, compare the md5sum between the NDB CCO image and image file copied to linux. Use the following command to check (linux):

cisco@NDB-virtual-machine:~/3.10.0/$ md5sum ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip
Displayed output: 685a0fe58f3280590dd878b7835241aa  ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip

Generating TLS certificate between NDB server and NDB switch for Embedded mode of deployment is not supported. For details about TLS, see the Managing TLS Certificate, KeyStore and TrustStore Files chapter in the Cisco Nexus Data Broker Configuration Guide.

Obtaining the Cisco Nexus Data Broker Embedded Software for NX-API

Procedure

Step 1

In a web browser, navigate to Cisco.com.

Step 2

In the center pane, click Cloud and Systems Management.

Step 3

If prompted, enter your Cisco.com username and password to log in.

Step 4

In the right pane, click Network Controllers and Applications, and then click Cisco Nexus Data Broker.

Step 5

Download and unzip the Cisco Nexus Data Broker Release 3.10 application bundle zip file.

Step 6

Download activator script. The Python activator script needed to activate the NDB is available at: https://github.com/datacenter/nexus-data-broker.

JRE is unbundled from NDB 3.10 release package. Activator script will take care of installing the packages if internet connectivity is available on the switch; else, JRE and unzip packages need to be downloaded from an authorized location and provided as an argument for the activator script.

What to do next

Install the software on supported Cisco Nexus series switches. See Cisco Nexus Data Broker Release 3.10, Release Notes for the list of supported platforms.

Installing and Activating the Cisco Nexus Data Broker Embedded Software for NX-API Mode for NX-OS 9.3(1) or Later

Cisco NDB is not installed as OVA, it is installed in the Guestshell. To install Cisco Nexus Data Broker Embedded software on NXOS 9.3(1) or later release, use the NDB activator script, NDBActivator4.0_9.3_plus.py.

The activator script performs the following functions:

  • Resizes the Guestshell resources.

  • Unzips and places the ndb folder into the /usr/bin directory.

  • Configures the Guestshell to management VRF.


Note

Cisco NDB Release 3.10 supports Oracle Java only.

Before you begin


Note
By default, you cannot install a new version of the Cisco Nexus Data Broker Embedded if you already have an existing Cisco Nexus Data Broker Embedded application installed and active. You can forcefully run the activator script even if it is already activated using python bootflash command with --force attribute. For example: 
Syntax: python <file path>NDBActivator4.0_9.3_plus.py –v guestshell+ <zip file path> --force

Example:  python bootflash:NDBActivator4.0_9.3_plus.py –v guestshell+ /bootflash/ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip --force

Note
To uninstall NDB application, destroy the Guestshell using the command, guestshell destroy. If an instance of NDB exists in the guestshell and you need to install a new NDB instance, you need to destroy the existing Guestshell and re-install the Guestshell and the NDB. 
N9K-switch# guestshell destroy

Note

After you disable and enable NXAPI mode, you should reconfigure nxapi use-vrf management command on the node.


Important

Ensure that you have sufficient space available in the bootflash. The ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip file require a total of ~600 MB of space in the bootflash (/volatile folder) for the decompression processes. The script runs only on NXOS platform, version 9.3(1), with memory greater than 8GB.

Procedure

Step 1

switch# copy ftp:/10.10.10.1 NDBActivator4.0_9.3_plus.py bootflash:vrf management

Copies the NDBActivator4.0_9.3_plus.py from the directory where you downloaded it to the switch. You can download the file from different sources such as HTTP, FTP, or SSH.

Step 2

switch# copy ftp://10.10.10.1 ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip bootflash:vrf management

Copies the Cisco Nexus Data Broker Embedded package from the directory where you downloaded it to the switch. You can download the file from different sources such as HTTP, FTP, or SSH.

Step 3

switch# show virtual-service list

Monitors the status of the copy processes.

Step 4

switch# guestshell enable

Enables the guestshell.

Step 5

switch# python bootflash:NDBActivator4.0_9.3_plus.py -v guestshell+ /bootflash/ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip

Installs the Cisco Nexus Data Broker Embedded package on the switch.

Note

 

Internet connectivity is needed for downloading the packages.

When internet connectivity is not available on the switch, follow these steps:

  1. Download JRE tar.gz file.

    Download Java from an authorized site. Click Linux x64 to download JRE tar.gz.

  2. Download (from an authorized site) and unzip RPM package.

  3. Copy JRE tar.gz file from the directory, where you downloaded it to the switch, using copy scp://10.10.10.1 jre-8u271-linux-x64.tar.gz bootflash: vrf management.

    Replace jre-8u271-linux-x64.tar.gz with the downloaded file name.

  4. Copy unzip rpm package from the directory where you downloaded it, to the switch, using copy scp://10.10.10.1 unzip-6.0-21.el7.x86_64.rpm bootflash:vrf management.

    Replace unzip-6.0-21.el7.x86_64.rpm with the downloaded file name.

  5. switch# python bootflash:NDBActivator4.0_9.3_plus.py -v guestshell+ /bootflash/ndb1000-sw-app-emb-9.3-plus-k9-3.10.0.zip /bootflash/jre-8u271-linux-x64.tar.gz /bootflash/unzip-6.0-21.el7.x86_64.rpm

Step 6

switch# show virtual-service list

Monitors the status of the installations.

Note

 

To start the NDB application, use the guestshell enable command. If the NDB application is initiated through the Python script, guestshell is enabled automatically.

Note

 

To stop the NDB application, use the guestshell disable command. Use guestshell enable command to enable NDB.

Note

 

Do not continue until installation completes successfully. NDB application starts after it is installed successfully.

Step 7

switch# show processes cpu sort | grep java

Example:

switch# show processes cpu sort | grep java

19587 3 6 551 0.00% java

switch#

Verify whether NDB installed and initiated successfully.

What to do next
