+---------------------------+-----------------+--------+---------------------------------------------------+

1.1 Extract the NED package


It is assumed the NED package ncs-<NSO version>-cisco-ftd-<NED version>.signed.bin has already been downloaded from software.cisco.com.

In this instruction the following example settings will be used:

  • NSO version: 6.0

  • NED version: 1.0.1

  • NED package downloaded to: /tmp/ned-package-store

  1. Extract the NED package and verify its signature:

    > cd /tmp/ned-package-store
    > chmod u+x ncs-6.0-cisco-ftd-1.0.1.signed.bin
    > ./ncs-6.0-cisco-ftd-1.0.1.signed.bin
  2. In case the signature can not be verified (for instance if no internet connection), do as below instead:

    > ./ncs-6.0-cisco-ftd-1.0.1.signed.bin --skip-verification
  3. The result of the extraction shall be a tar.gz file with the same name as the .bin file:

    > ls *.tar.gz
    ncs-6.0-cisco-ftd-1.0.1.tar.gz

1.2 Install the NED package


There are two alternative ways to install this NED package. Which one to use depends on how NSO itself is setup.

In the instructions below the following example settings will be used:

  • NSO version: 6.0

  • NED version: 1.0.1

  • NED download directory: /tmp/ned-package-store

  • NSO run time directory: ~/nso-lab-rundir

A prerequisite is to set the environment variable NSO_RUNDIR to point at the NSO run time directory:

> export NSO_RUNDIR=~/nso-lab-rundir

1.2.1 Local install


This section describes how to install a NED package on a locally installed NSO (see "NSO Local Install" in the NSO Installation guide).

It is assumed the NED package has been been unpacked to a tar.gz file as described in 1.1.

  1. Untar the tar.gz file. This creates a new sub-directory named:cisco-ftd-<NED major digit>.<NED minor digit>:

    > tar xfz ncs-6.0-cisco-ftd-1.0.1.tar.gz
    > ls -d */
    cisco-ftd-gen-1.0
  2. Install the NED into NSO, using the ncs-setup tool:

    > ncs-setup --package cisco-ftd-gen-1.0 --dest $NSO_RUNDIR
  3. Open a NSO CLI session and load the new NED package like below:

    > ncs_cli -C -u admin
    admin@ncs# packages reload
    reload-result {
        package cisco-ftd-gen-1.0
        result true
    }

Alternatively the tar.gz file can be installed directly into NSO. Then skip steps 1 and 2 and do like below instead:

  > ncs-setup --package ncs-6.0-cisco-ftd-1.0.1.tar.gz --dest $NSO_RUNDIR
  > ncs_cli -C -u admin
  admin@ncs# packages reload
  reload-result {
    package cisco-ftd-gen-1.0
    result true
 }

1.2.2 System install


This section describes how to install a NED package on a system installed NSO (see "NSO System Install" in the NSO Installation Guide).

It is assumed the NED package has been been unpacked to a tar.gz file as described in 1.1.

  1. Do a NSO backup before installing the new NED package:

    > $NCS_DIR/bin/ncs-backup
  2. Start a NSO CLI session and fetch the NED package:

    > ncs_cli -C -u admin
    admin@ncs# software packages fetch package-from-file \
              /tmp/ned-package-store/ncs-6.0-cisco-ftd-1.0.tar.gz
    admin@ncs# software packages list
    package {
     name ncs-6.0-cisco-ftd-1.0.tar.gz
     installable
    }
  3. Install the NED package (add the argument replace-existing if a previous version has been loaded):

    admin@ncs# software packages install cisco-ftd-1.0
    admin@ncs# software packages list
    package {
     name ncs-6.0-cisco-ftd-1.0.tar.gz
     installed
    }
  4. Load the NED package

    admin@ncs# packages reload
    admin@ncs# software packages list
    package {
      name ncs-6.0-cisco-ftd-gen-1.0
      loaded
    }

1.3 Configure the NED in NSO


This section describes the steps for configuring a device instance using the newly installed NED package.

  • Start a NSO CLI session:

    > ncs_cli -C -u admin
  • Enter configuration mode:

    admin@ncs# configure
    Entering configuration mode terminal
    admin@ncs(config)#
  • Configure a new authentication group (my-group) to be used for this device:

    admin@ncs(config)# devices authgroup group my-group default-map remote-name <user name on device> \
                       remote-password <password on device>
  • Configure a new device instance (example: dev-1):

    admin@ncs(config)# devices device dev-1 address <ip address to device>
    admin@ncs(config)# devices device dev-1 port <port on device>
    admin@ncs(config)# devices device dev-1 device-type generic ned-id cisco-ftd-gen-1.0
    admin@ncs(config)# devices device dev-1 state admin-state unlocked
    admin@ncs(config)# devices device dev-1 authgroup my-group
  • Optionally set the ssl to accept-any

    • Accept any certificate (unsafe).Accept any SSL certificate presented by the device.Warning! This enables Man in the Middle attacks and should only be used for testing and troubleshooting.

    admin@ncs(config)# devices device dev-1 ned-settings connection ssl accept-any
  • Optionally configure HA (High Availability) related settings:

    • The NED can automatically connect to the other device in the HA pair. The NED has an alternate ip list containing other nodes in HA. If the NED could not connect (get the api version and get the auth token) to the main configured ip, it will try one by one the nodes in the list until it will find one that can be connected.

    • Erasing alternative hosts list:

    admin@ncs(config)# no devices device dev-1 ned-settings cisco-ftd connection ha alternative-hosts
    • Configuring alternative host list:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd connection ha alternative-hosts x.x.x.x
    • By default the NED will read the HA status of the hosts in the alternative-hosts and wait for the status to become HA_ACTIVE_NODE. If the node does not become HA_ACTIVE_NODE in 60 seconds an error will be thrown.

    • The HA state checking feature can be disabled by:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd connection ha check-ha-active false
    • The NED can automatically call HA (High Availability) Join after HA is configuration is commited. To enable this:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior callHaJoinAfterHaConfig true
  • Optionally configure custom NED behaviour that may be helpful in some situations:

    • The NED can automatically call HA (High Availability) Join after HA is configuration is commited. To enable this:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior callHaJoinAfterHaConfig true
    • The NED can automatically deploy the configuration after each commit. To enable this:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior enableAutoDeploy true
    • The NED can automatically end the initial easy setup device state. To enable this:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior autoEndEasySetup true
    • The device does not return the token value for the: cisco-ftd:ftd license smartagentconnections smartagentconnection token. The NED cand handle this behaviour by reading the last value of the token from its configuration database at sync-from. To enable this:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior retrieve-old-license-token-val true
  • Finally commit the configuration

    admin@ncs(config)# commit
  • Verify configuration, using a sync-from.

    admin@ncs(config)# devices device dev-1 sync-from
    result true

If the sync-from was not successful, check the NED configuration again.

2. Optional debug and trace setup


It is often desirable to see details from when and how the NED interacts with the device(Example: troubleshooting)

This can be achieved by configuring NSO to generate a trace file for the NED. A trace file contains information about all interactions with the device. Messages sent and received as well as debug printouts, depending on the log level configured.

NSO creates one separate trace file for each device instance with tracing enabled. Stored in the following location:

$NSO_RUNDIR/logs/ned-cisco-ftd-gen-1.0-<device name>.trace

Do as follows to enable tracing in one specific device instance in NSO:

  1. Start a NSO CLI session:

    > ncs_cli -C -u admin
  2. Enter configuration mode:

    admin@ncs# configure
    Entering configuration mode terminal
    admin@ncs(config)#
  3. Enable trace raw:

    admin@ncs(config)# devices device dev-1 trace raw
    admin@ncs(config)# commit

    Alternatively, tracing can be enabled globally affecting all configured device instances:

    admin@ncs(config)# devices global-settings trace raw
    admin@ncs(config)# commit
  4. Configure the log level for printouts to the trace file:

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd logger \
                      level [debug | verbose | info | error]
    admin@ncs(config)# commit

    Alternatively the log level can be set globally affecting all configured device instances using this NED package.

    admin@ncs(config)# devices device global-settings ned-settings cisco-ftd logger \
                      level [debug | verbose | info | error]
    admin@ncs(config)# commit

The log level 'info' is used by default and the 'debug' level is the most verbose.

IMPORTANT: Tracing shall be used with caution. This feature does increase the number of IPC messages sent between the NED and NSO. In some cases this can affect the performance in NSO. Hence, tracing should normally be disabled in production systems.

An alternative method for generating printouts from the NED is to enable the Java logging mechanism. This makes the NED print log messages to common NSO Java log file.

$NSO_RUNDIR/logs/ncs-java-vm.log

Do as follows to enable Java logging in the NED

  1. Start a NSO CLI session:

    > ncs_cli -C -u admin
  2. Enter configuration mode:

    admin@ncs# configure
    Entering configuration mode terminal
    admin@ncs(config)#
  3. Enable Java logging with level all from the NED package:

    admin@ncs(config)# java-vm java-logging logger com.tailf.packages.ned.ftd \
                      level level-all
    admin@ncs(config)# commit
  4. Configure the NED to log to the Java logger

    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd logger java true
    admin@ncs(config)# commit

    Alternatively Java logging can be enabled globally affecting all configured device instances using this NED package.

    admin@ncs(config)# devices global-settings ned-settings cisco-ftd logger java true
    admin@ncs(config)# commit

IMPORTANT: Java logging does not use any IPC messages sent to NSO. Consequently, NSO performance is not affected. However, all log printouts from all log enabled devices are saved in one single file. This means that the usability is limited. Typically single device use cases etc.

6. Built in live-status show


NONE

7. Limitations


7.1 Smartagentconnection token limitation

The device does not return the token value for the: cisco-ftd:ftd license smartagentconnections smartagentconnection token. The NED cand handle this behaviour by reading the last value of the token from its configuration database at sync-from. To enable this:

```
admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd nedBehavior retrieve-old-license-token-val true
```

8. How to report NED issues and feature requests


Issues like bugs and errors shall always be reported to the Cisco NSO NED team through the Cisco Support channel:

The following information is required for the Cisco NSO NED team to be able to investigate an issue:

- A detailed recipe with steps to reproduce the issue.
- A raw trace file generated when the issue is reproduced.
- Access to a device where the issue can be reproduced by the Cisco NSO NED team.
  This typically means both read and write permissions are required.
  Pseudo access via tools like Webex, Zoom etc is not acceptable.
  However, it is ok with device access through VPNs, jump servers etc though.

Do as follows to gather the necessary information needed for your device, here named 'dev-1':

  1. Enable full debug logging in the NED

    ncs_cli -C -u admin
    admin@ncs# configure
    admin@ncs(config)# devices device dev-1 ned-settings cisco-ftd logging level debug
    admin@ncs(config)# commit
  2. Configure the NSO to generate a raw trace file from the NED

    admin@ncs(config)# devices device dev-1 trace raw
    admin@ncs(config)# commit
  3. If the NED already had trace enabled, clear it in order to submit only relevant information

    Do as follows for NSO 6.4 or newer:

    admin@ncs(config)# devices device dev-1 clear-trace

    Do as follows for older NSO versions:

    admin@ncs(config)# devices clear-trace
  4. Run a compare-config to populate the trace with initial device config

    admin@ncs(config)# devices device dev-1 compare-config
  5. Reproduce the found issue using ncs_cli or your NSO service. Write down each necessary step in a reproduction report.

  6. Gather the reproduction report and a copy of the raw trace file containing data recorded when the issue happened.

  7. Contact the Cisco support and request to open a case. Provide the gathered files together with access details for a device that can be used by the Cisco NSO NED when investigating the issue.

Requests for new features and extensions of the NED are handled by the Cisco NSO NED team when applicable. Such requests shall also go through the Cisco support channel.

The following information is required for feature requests and extensions:

  1. A detailed use case description, with details like:

    • Data of interest

    • The kind of operations to be used on the data. Like: 'read', 'create', 'update', 'delete' and the order of the operation

    • Device APIs involved in the operations (For example: REST URLs and payloads)

    • Device documentation describing the operations involved

  2. Run sync-from # devices device dev-1 sync-from (if relevant)

  3. Attach the raw trace to the ticket (if relevant)

  4. Access to a device that can be used by the Cisco NSO NED team for testing and verification of the new feature. This usually means that both read and write permissions are required. Pseudo access via tools like Webex, Zoom etc is not acceptable. However, it is ok with access through VPNs, jump servers etc.
