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/cisco-staros/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/cisco-staros/ device /ncs:/device/devices/device:/ned-settings/cisco-staros/
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 cisco-staros
Press TAB to see all the NED settings.
This ned-setting can be used to add dynamic dependency rules to the NED before being permanently fixed in the NED. This can be useful if a dependency bug is found and you do not want to upgrade the NED or are in a hurry for the fix.
regexp entry list to filter configs from sync-from.
7. ned-settings cisco-staros hidden-mode
This ned-settings used to set/modify hidden configs on the device. To configure hidden configs through NED, user must configure both "enable-hidden-mode=true" and "test-commands-password=".
These ned-settings are used to retry config commands on certain device warning or error.
Example: Sometime AAA server is overloaded, it throws an intermittent error back to device ( Ex GTAC Failure: communication link down), which in turn throws it back to NSO/NED which starts auto-rollback. In such a scenario, use this ned-settings to NED to retry the command and not start auto-rollback immediately.
After having sent a config command to the device the NED will treat any text reply as an error and abort the transaction. The config command that caused the failed transaction will be shown together with the error message returned by the device. Sometimes the text message is not an actual error. It could be a warning that should be ignored. The NED has a static list of known warnings.:
If you stumble upon a warning not in NED's static list, which is quite likely due to the large number of warnings or some customers are interested in aborting commit if NED receives those warnings from device, you can configure NED to ignore them using this ned-settings.
- extended-parser <enum> (default auto)
Make the cisco-staros NED handle CLI parsing (i.e. transform the running-config from the
device to the model based config tree).
disabled - [DEPRECATED] Load configuration the standard way.
old-robust-mode - [DEPRECATED] Makes the NED alter the config dump such that all mode
switches are always done from top and down instead of from below and up
(with the 'exit' command) before given to the NCS/NSO parser.The number of
lines in the config dump will increase a lot with this feature enabled.
(default).
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 - [DEPRECATED] 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 available method to load
data to NSO. If NSO doesn't support data-loading from CLI NED, robust-mode
is used.
- write-memory-setting <enum> (default on-commit)
Configure how and when an applied config is saved to persistent memory on the device.
on-commit - Save configuration immediately after the config has been successfully applied on
the device. If an error occurs when saving the whole running config will be
rolled back.
on-persist - Save configuration during the NED persist handler. Called after the config has
been successfully applied and committed, if an error occurs when saving an alarm
will be triggered. No rollback of the running config is done.
disabled - Disable saving the applied config to persistent memory.
- write-config-file <string> (default /flash/system.cfg)
Configure where configuration should be saved on the device.
- disable-encrypted-configs <true|false> (default false)
Disbale encrypted configs yang nodes in NED.
- ruledef-rules-as-ordered-by-user <true|false> (default false)
This ned-settings used to handle all rules as 'ordered-by user' inside
/active-charging/service/ruledef. All rules(sub-nodes) inside ruledef are now just
a string, and ordered-by user. By default this feature is disabled. Set this ned-setting
to true to use 'ordered-by user' rules feature in NED.
- host-pool-ip-as-ordered-by-user <true|false> (default false)
This ned-settings used to handle all IPs as 'ordered-by user' inside
/active-charging/service/host-pool/ip. All IPs are now just a string,
and ordered-by user. By default this feature is disabled. Set this ned-setting to
true to use 'ordered-by user' IP feature in NED.
- apn-ip-qos-dscp-as-single-line-syntax <true|false> (default false)
/context/apn/ip/qos-dscp entries can be configured as multiple lines
or all entries in single line. New yang models introduced to support STAROS single
line syntax. Multiple lines and single line yang nodes controlled by
apn-ip-qos-dscp-as-single-line-syntax ned-setting. By default multiple lines yang
syntax are supported. Set this ned-setting to true to use single line syntax feature in NED.
- use-context-ssh-key <true|false> (default false)
By default /context/ssh/generate/key enabled in yang model and
'ssh key <key> len <length> type v2-rsa' command transformed to
'ssh generate key type v2-rsa' during sync-from. Configure use-context-ssh-key to true,
to enable /context/ssh/key yang model and to keep original ssh key during sync-from.
- connection number-of-retries <uint8> (default 0)
Configure max number of retries the NED will try to connect to the device before giving up.
- connection time-between-retry <uint8> (default 1)
Configure the time in seconds the NED will wait between each connect retry.
- live-status time-to-live <int32> (default 50)
Define time-to-live for data fetched from the device via live-status.
- read replace-config <id> <regexp> <replacement> <when>
- id <WORD>
List id, any string.
- regexp <WORD>
The regular expression (DOTALL) to which the config is to be matched.
- replacement <WORD>
The string which would replace all found matches. May use groups from regex. Leave unset for
filtering.
- when <enum>
trans-id-only - Only replace/filter when calculating transaction id.
Example:
# devices device <name> ned-settings cisco-staros read replace-config tech-support-replace regexp
"\s+tech-support test-commands encrypted password \S+" replacement "\n tech-support test-commands password test_password"
- write context-ip-pool-modify-syntax <true|false> (default false)
Problem 1:
/context/ip/pool yang model is compact-syntax and NSO can not generate
individual leaf modification syntax. Moreover not all leaves inside
/context/ip/pool can be modified, when sending modified value together
with other leaves as compact-syntax, we get below errors.
Failure: Cannot modify Pool, once pool is configured!
or
Failure: Modification of existing pools to NAT pools not allowed!
Solution 1:
NED removes and re-creates if there is any value change in a leaf.
Problem 2:
NAT pools (ip pool) which is mapped/shared with multiple customer, deleting
and creating is highly impossible. Customer asked to StarOS BU to add below
feature to modify the nat-binding-timer/port-chunk-hold-timer dynamically
without effecting customer in existing NAT pools.
i.e `ip pool test-pool-name nat-binding-timer <int> port-chunk-hold-timer <int>`
Solution 2:
If only nat-binding-timer/port-chunk-hold-timer value changed, send only these
modification to device instead of remove and re-create.
NOTE: solution 2 works only when changing nat-binding-timer/port-chunk-hold-timer,
if other leafs modified together then syntax will be remove and re-create.
