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/riverbed-steelhead/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/riverbed-steelhead/ device /ncs:/device/devices/device:/ned-settings/riverbed-steelhead/

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 riverbed-steelhead

Press TAB to see all the NED settings.

1. ned-settings riverbed-steelhead

---

Configure settings specific to the connection between NED and device.

- extended-parser <enum> (default auto)

  Make the riverbed-steelhead 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. If NSO doesn't support data-loading from CLI NED, robust-mode
                    is used.

  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.

  robust-mode     - Makes the NED filter the configuration so that unmodeled content is removed
                    before being passed to the NSO CLI-engine. This protects against
                    configuration ending up at the wrong level when NSO CLI parser fallbacks
                    (which potentially can cause following config to be skipped).

2. ned-settings riverbed-steelhead connection

---

Configure settings specific to the connection between NED and device.

- 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 connector <WORD>

  Change the default connector, e.g. 'ned-connector-default.json'.


- 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.

3. ned-settings riverbed-steelhead deprecated

---

Deprecated ned-settings.

- deprecated connection legacy-mode <enum> (default disabled)

  enabled   - enabled.

  disabled  - disabled.

4. ned-settings riverbed-steelhead logger

---

Settings for controlling logs generated.

- logger level <enum> (default debug)

  Set level of logging.

  error    - error.

  info     - info.

  verbose  - verbose.

  debug    - debug.


- logger java <true|false> (default true)

  Toggle logs to be added to ncs-java-vm.log.

5. ned-settings riverbed-steelhead live-status

---

Configure NED settings related to live-status.

- live-status time-to-live <int32> (default 50)

  Define time-to-live for data fetched from the device via live-status.(default 50).

6. ned-settings riverbed-steelhead proxy

---

Configure NED to access device via a proxy.

- proxy remote-connection <enum>

  Connection type between ned, proxy and device.

  ssh            - Start a new ssh client on proxy and connect to device (i.e. will launch
                   interactive shell on proxy).
