# README-ned-settings ## 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/zte-xpon/ profile /ncs:devices/ncs:profiles/profile:/ned-settings/zte-xpon/ device /ncs\:/device/devices/device:/ned-settings/zte-xpon/ 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 zte-xpon Press TAB to see all the NED settings. ``` ## Table of contents *** ``` 1. ned-settings zte-xpon 2. live-status 3. connection 4. proxy 5. proxy-2 6. developer 7. console 7.1. warning 7.2. command 7.3. pattern 7.4. action 7.4.1. state 8. logger ``` ## 1. ned-settings zte-xpon *** Per-device settings for zte-xpon. ``` - extended-parser (default auto) Make the 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. - internal-xml-transfer-timeout (default 2147483647) Configure maximum time in milliseconds allowed for transferring XML from NED to NSO. - use-write (default true) - set to True to send WRITE command at commit (Default) - set to False to skip sending WRITE command - wait-time (default 0) Some devices need more time to process some commands, before accepting others. E.g: interface gpon-olt_*/onu */type * The ned-settings zte-xpon wait-time is the value in seconds to wait after the above command was sent to the device. ``` ## 2. ned-settings zte-xpon live-status *** Configure NED settings related to live-status. ``` - live-status time-to-live (default 50) Define time-to-live for data fetched from the device via live-status.(default 50). ``` ## 3. ned-settings zte-xpon connection *** Configure settings specific to the connection between NED and device. ``` - connection ssh client 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 Path to openssh formatted 'known_hosts' file containing valid host keys. - connection ssh host-key public-key-file Path to openssh formatted public (.pub) host key file. - connection ssh auth-key private-key-file Path to openssh formatted private key file. - connection ssh keep-alive-interval (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 (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 (default 1) Configure the time in seconds the NED will wait between each connect retry. Default 1s. - connection character-set (default UTF-8) Character set to use for telnet session. - connection commands meta-data Change the default connector. Default 'ned-connector.json'. - connection commands initial-action Interactor action used to initialize a connection. - connection commands awaken-console Command sent to awaken console during connection. - connection commands send-delay (default 0) Delay in ms before sending a command during connection. - connection commands expect-timeout (default 60000) Default limit in ms for waiting for command response. - connection logger silent (default false) Toggle detailed logs to only written to store. - connection terminal server-echo (default false) Enable (TELNET) server echo, i.e. use DO ECHO instead of DONT ECHO. - connection terminal println-mode (default default) default - System property line.separator default. ocrnl - Translate carriage return to newline. onocr - Translate newline to carriage return-newline. onlret - Newline performs a carriage return. - connection device-prompt (default \A[\S ]+#[ ]?$) When doing a READ, the ned will do a "show configuration" command and get everything until the prompt occurs. To do that, we need a prompt regexp match. By default it is set to "\A[\S ]+#[ ]?$". In cases where the device actually contains a configuration matching the prompt (e.g digit-map), there will be an early stop at reading the running config, caused by the false match. This can be avoided by changing the regexp to properly match the device prompt ``` ## 4. ned-settings zte-xpon proxy *** Configure NED to access device via a proxy. ``` - proxy remote-connection Connection type between proxy and device. ssh - SSH jump host proxy. telnet - TELNET jump host proxy. serial - Terminal server proxy. - proxy remote-address Address of host behind the proxy. - proxy remote-port Port of host behind the proxy. - proxy remote-command Connection command used to initiate proxy on device. Optional for ssh/telnet. Accepts $(proxy/remote-xxx) for inserting remote-xxx config. - proxy remote-name User name on the device behind the proxy. - proxy remote-password Password on the device behind the proxy. - proxy authgroup Authentication credentials for the device behind the proxy. - proxy proxy-prompt Prompt pattern on the proxy host. - proxy remote-ssh-args Additional arguments used to establish proxy connection (appended to end of ssh cmd line). ``` ## 5. ned-settings zte-xpon proxy-2 *** Configure NED to access device via a second proxy. ``` - proxy-2 remote-connection Connection type between proxy and device. ssh - SSH jump host proxy. telnet - TELNET jump host proxy. serial - Terminal server proxy. - proxy-2 remote-address Address of host behind the proxy. - proxy-2 remote-port Port of host behind the proxy. - proxy-2 remote-command Connection command used to initiate proxy on device.
