NED settings details

---

This NED is equipped with a number of runtime configuration options "NED settings" allowing for customization by the end user. All options are configurable using the NSO API for NED settings. Most NED settings can be configured globally, per device profile or per device instance in the following locations:

global /ncs:devices/global-settings/ned-settings/vecima-eac/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/vecima-eac/ device /ncs:/device/devices/device:/ned-settings/vecima-eac/

Profiles setting overrides global-settings and device settings override profile settings, hence the narrowest scope of the setting is used by the device.

If user changes a ned-setting, then user must reconnect to the device, i.e. disconnect and connect in order for the new setting to take effect.

From the NSO CLI the device instance NED settings for this NED are available under:

# config
# devices device dev-1 ned-settings vecima-eac

Press TAB to see all the NED settings.

1. ned-settings vecima-eac

---

- extended-parser <enum> (default auto)

  Make the cisco-nx NED handle CLI parsing (i.e. transform the running-config from the device to
  the model based config tree).

  auto            - Uses turbo-mode when available, will use fastest availablemethod to load
                    data to NSO.

  turbo-mode      - The NED executes the whole command parsing by itself, completely bypassing
                    the NSO CLI parser. The configuration dump is transferred to NSO using maapi
                    setvalues call.

  turbo-xml-mode  - The NED executes the whole command parsing by itself, completely bypassing
                    the NSO CLI parser. The configuration dump is transferred to NSO in XML
                    format.

2. ned-settings vecima-eac developer

---

Contains settings used by the NED developers.

- developer load-from-file <string>

  Make the NED load a file containing raw device config when doing sync-from. Does only work on
  NETSIM targets.


- developer platform model <string>

  Override device model name/number.


- developer platform name <string>

  Override device name.


- developer platform version <string>

  Override device version.


- developer device-type <enum> (default netsim)

  Real or simulated device.

  netsim  - netsim.

  device  - device.


- developer trace-enable <true|false> (default false)

  Enable developer tracing. WARNING: may choke NSO with large commits|systems.


- developer trace-connection <true|false> (default false)

  Enable connection tracing. WARNING: may choke NSO with IPC messages.


- developer trace-timestamp <true|false> (default false)

  Add timestamp from NED instance in trace messages for debug purpose.


- developer progress-verbosity <enum> (default verbose)

  Maximum NED verbosity level which will get written in devel.log file.

  disabled      - disabled.

  normal        - normal.

  verbose       - verbose.

  very-verbose  - very-verbose.

  debug         - debug.


- developer load-native-config allow-delete <true|false> (default false)

  Enable this setting to be able to handle limited delete operations with 'load-native-config'. Please note that
  not all syntax available on a real device works, some delete operations can not be parsed by the NED. Use the
  'verbose' flag to 'load-native-config' to see if delete commands can be parsed. Currently this is only supported
  when 'extended-parser' is set to 'turbo-xml-mode'


- developer load-native-config delete-with-remove <true|false> (default false)

  Enable this setting to use 'remove' instead of 'delete' when sending delete operations to NSO. This is useful when
  doing delete commands for data that might not be present in CDB. Please note that deletes for missing data will still
  be part of transaction, and will be sent to device. Use with care, and do proper testing to understand behaviour.

3. ned-settings vecima-eac proxy

5. ned-settings vecima-eac connection

---

Configure settings specific to the connection between NED and device.

- connection ssh client <enum>

  Configure the SSH client to use. Relevant only when using the NED with NSO 5.6 or later.

  ganymed  - The legacy SSH client. Used on all older versions of NSO.

  sshj     - The new SSH client with support for the latest crypto features. This is the default
             when using the NED on NSO 5.6 or later.


- connection ssh host-key known-hosts-file <string>

  Path to openssh formatted 'known_hosts' file containing valid host keys.


- connection ssh host-key public-key-file <string>

  Path to openssh formatted public (.pub) host key file.


- connection ssh auth-key private-key-file <string>

  Path to openssh formatted private key file.


- connection ssh keep-alive-interval <seconds> (default 0)

  Configure SSH client keep alive interval in seconds, default 0 (i.e. no keep-alive). The
  keep-alive is implemented in the client by sending an ssh 'ignore' message on the given
  interval.


- connection number-of-retries <uint8> (default 0)

  Configure max number of retries the NED will try to connect to the device before giving up.
  Default 0.


- connection time-between-retry <uint8> (default 1)

  Configure the time in seconds the NED will wait between each connect retry. Default 1s.


- connection character-set <string> (default UTF-8)

  Character set to use for telnet session.


- connection commands meta-data <WORD>

  Change the default connector. Default 'ned-connector.json'.


- connection commands initial-action <union>

  Interactor action used to initialize a connection.


- connection commands awaken-console <string>

  Command sent to awaken console during connection.


- connection commands send-delay <uint32> (default 0)

  Delay in ms before sending a command during connection.


- connection commands expect-timeout <uint32> (default 60000)

  Default limit in ms for waiting for command response.


- connection logger silent <true|false> (default false)

  Toggle detailed logs to only written to store.

6. ned-settings vecima-eac transaction

---

Transaction specific settings.

- transaction trans-id-method <enum> (default modeled-config)

  Select the method for calculating transaction-id.

  modeled-config  - Use a snapshot of the data of only the modeled parts of running config for
                    calculation.

  full-config     - Use a snapshot of the full running config for calculation.

  device-custom   - Use a device custom method to get a value to use for trans-id.


- transaction abort-on-diff <true|false> (default false)

  Enable to detect diff immediately when config is applied (i.e. in commit/abort/revert).
  If a diff is detected an exception is thrown, having the effect in commit that the transaction
  is aborted (showing the diff). Note that this means some overhead in commit, where whole config
  needs to be retrieved from device to do compare. It's a more exact way to detect OOB changes,
  silently dropped config, and unknown side-effects to config (i.e. all causing a diff compared 
  to NSO state). In fact, it's the only method which guarantees that the config was actually 
  applied as desired. Since this incurs overhead it is strongly adviced that this feature is
  only used during development.
