Syncing the Guest Shell Rootfs to the Standby Supervisor and Querying the Result

This section contains payload examples to demonstrate how to use the NX-API REST API to control the state of the Guest Shell on the Cisco Nexus 3000 and 9000 Series switches.

For more information about the Guest Shell, see the Cisco Nexus 9000 Series NX-OS Programmability Guide:

https://www.cisco.com/c/en/us/support/switches/nexus-9000-series-switches/products-installation-and-configuration-guides-list.html/

Syncing the Guest Shell Rootfs to the Standby Supervisor

Syncing the Guest Shell Rootfs to the Standby Supervisor

POST http://<IP_address>/api/mo/sys/action.json

{
"actionLSubj": {
  "attributes": {
    "dn": "sys/action/lsubj-[sys]"
  }
  "children": [{
    "guestshellGuestShellSyncLTask": {
      "attributes": {
        "adminSt": "start",
        "dn": "sys/action/lsubj-[sys]/guestshellGuestShellSyncLTask",
        "freq": "one-shot",
        "descr": "This is description string in LTask"
}}}]}}

Note: This example was added in Release 9.3(3).

If the Cisco Nexus 9000 Series switch in use has dual supervisors, and you want a duplicate copy of the Guest Shell rootfs that is used on active supervisor on the standby supervisor, post a guestshellGuestShellSyncLTask action. If the Guest Shell was activated when this request was posted, the Guest Shell is deactivated for a copy of the rootfs to be copied to the standby supervisor and then reactivated.

CLI Commands

The CLI command is equivalent to the payload example displayed in the pane on the right.

                }
            }
        }
    ]
}

Note: This example was added in Release 9.3(3).

The endTs of “never” and operSt of “processing” indicates that the sync request is being processed, but it has yet to finish. Repeating the request for the sync result after some time shows an operSt attribute of “completed” and the time in which the disable request finished in the endTs attribute.

Note: This example was added in Release 9.3(3).

In this example, the Guest Shell was in the activated state when the sync request was posted and it returned to the activated state as indicated in the descr attribute

If the sync request is posted to a system without a secondary supervisor, or it is offline, operSt will be “failed” and the description will indicate that the standby is not online.
