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/casa-ccap/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/casa-ccap/ device /ncs:/device/devices/device:/ned-settings/casa-ccap/
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 casa-ccap
Press TAB to see all the NED settings.
- casa-ccap persist <true|false> (default true)
this option will disable the 'copy running config to start up config' command that's issued
after commit.
- casa-ccap trans-id-method <enum> (default config-hash)
Configure how the NED shall calculate the transaction id. Typically used after each commit and
for check-sync operations.
config-hash - Use a snapshot of the running config for calculation.(default).
rollback-timestamp - Use the time stamp of the latest rollback checkpoint for
calculation. The system rollback feature must be on.
last-modified-timestamp - Use the 'time last modified' time stamp generated by the ALU device
for calculation. Note, this time stamp is not available on all ALU
devices. See README.
last-saved-timestamp - Use the 'time last saved' time stamp generated by the ALU device
for calculation. Note, this method is not reliable. See README.
- casa-ccap candidate-commit <enum> (default disabled)
Make the NED use the candidate commit feature available on some ALU devices.
disabled - Apply configuration the standard way, one-by-one. (default).
enabled - Apply configuration into a candidate and then commit it.The candidate feature must
be enabled on the device.
- casa-ccap extended-parser <enum> (default auto)
Make the cisco-aireos NED handle CLI parsing (i.e. transform the running-config from the
device to the model based config tree).
disabled - Load configuration the standard way.
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).
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.
- casa-ccap number-of-lines-to-send-in-chunk <uint8> (default 100)
Number of commands lines in a chunk sent by the casa-ccap NED to the device. Default is 100. A
higher number normally result in better performance but will also have negative impact on the
error handling. This command does also control the chunk sizes used in partial show bulk
mode.
- casa-ccap partial-show-method <enum> (default bulk-mode)
Method to use when executing a partial show on the device (for instance when doing a 'commit
no-overwrite').
bulk-mode - The NED executes in a bulk mode fashion. Commands to display config on the
requested locations on the device are sent in chunks to minimize the round trip
time. The result is gathered when all commands have been sent to the device.
(default).
walk-mode - The NED walks the config tree on the device step by step and extracts the
config on the requested locations. This method is much slower than bulk mode
but can be an alternative for devices that are not able to handle chunks of
commands properly.
filter-mode - The NED fetches a full configuration dump from the device. It then filters out
everything except the requested the parts. The filtered config is then sent
back to NSO.
- meta-data shutdown-before-set <enum> (default enabled)
This operation makes the NED shutdown a parent before (given by path) setting the value of
this leaf. Enabled by default.
enabled - enabled.
disabled - disabled.
- meta-data redeploy <enum> (default enabled)
This operation makes the NED redeploy another leaf (given by path) after setting the value of
this leaf. Enabled by default.
enabled - enabled.
disabled - disabled.
