playbook crash with md-cli config

[nkhambal]

Running this playbook leads to the crash. It looks like module cli_config is trying to run 'show system information' command from "configure private" mode. The correct syntax should be "/show system information". How do we fix that? The error is coming from capabilities code. When I comment out the code at ansible/netcommon/plugins/modules/cli_config.py", line 414 that gathers the capabilities, the playbook runs fine but the configuration is not getting applied. Config I am trying to push is simple port description in MD-CLI

/configure port 1/1/c5 description "TEST-P2-TO-XXXXXX-BB-CR2|1/1/C5|AE1|-|-|BB"
/configure port 1/1/c5/1 description "TEST-P2-TO-XXXXXX-BB-CR2|1/1/C5|AE1|-|-|BB"
/configure port 1/1/c6 description "TEST-P2-TO-XXXXXX-BB-CR2|1/1/C6|AE1|-|-|BB"
/configure port 1/1/c6/1 description "TEST-P2-TO-XXXXXX-BB-CR2|1/1/C6|AE1|-|-|BB"

Running this directly on the router gives the same error

Hello @nkhambal,

Did you resolve this problem already?
Please look at the Nokia MD-CLI playbook example

The syntax your using isn't the same as in the Nokia MD-CLI sample as linked above your using:
cli_command:
command: configure private

vs the sample:
cli_config:
config: |
configure private

[wisotzky]

@nkhambal, the cli_config should take care about changing into configuration mode and to finally commit the change. It must not be manually to ensure function.

[nkhambal]

Following playbook worked with one exception of "commit" tag. It commits even when it is set to "No". Is there an option to perform a commit "validate" and then "rollback" without actually committing the configuration?

Replying the answer to my own query. To skip commit and discard candidate after validate, use "commit: False". Default is "commit: True". Following playbook worked. It fetches the template and generates the configuration (deleting mpls lsp configuration in this case) and pushes it via cli_config. Does compare, validate and then discards the configuration providing the diff.

NOTE: make sure you use "delete configure router" and not just "delete router" in the template. Later works with "configure private" but not "edit-config private" which is what the module uses to configure the device.
