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/huawei-ias/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/huawei-ias/ device /ncs:/device/devices/device:/ned-settings/huawei-ias/
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 huawei-ias
Press TAB to see all the NED settings.

- extended-parser <enum> (default auto)
Make the huawei-ias 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 huawei-ias 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 model <string>
Simulate a model number. Include 'NETSIM' for netsim.
- developer progress-verbosity <enum> (default debug)
Maximum NED verbosity level which will be reported.
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.
- developer platform model <string>
Override device model name/number.
- developer platform name <string>
Override device name.
- developer platform version <string>
Override device version.3. ned-settings huawei-ias proxy

$(proxy/remote-xxx) for inserting remote-xxx config.
- proxy remote-name <string>
User name on the device behind the proxy.
- proxy remote-password <string>
Password on the device behind the proxy.
- proxy proxy-prompt <string>
Prompt pattern on the proxy host before connecting to device.
- proxy remote-ssh-args <string>
Additional arguments used to establish proxy connection.4. ned-settings huawei-ias connection
