API for "show interfaces ethernet" does not include the interface description
Closed, ResolvedPublicBUG


From the API, when I run the command "show interfaces ethernet", I don't see the provisioned description in the output:

[email protected]:~# curl -ks --location --request POST '' --form data='{"op": "show", "path": ["interfaces", "ethernet", "eth0", "brief"]}' --form key='api-key' | jq
  "success": true,
  "data": "Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down\nInterface        IP Address                        S/L  Description\n---------        ----------                        ---  -----------\neth0                    u/u  \n",
  "error": null

I expect the output to be the same as from the CLI:

[email protected]:~$ show interfaces ethernet
Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface        IP Address                        S/L  Description
---------        ----------                        ---  -----------
eth0                    u/u  Internet Access
eth1                      u/u  Local Access

You can see in the API return values, the Description field is missing (although the header is there in the output). I would like to use the description field in the API results in a script, but cannot since the value is not returned via the API.

Event Timeline

I notice my example of the API only focused on one interface (eth0), where the CLI (and the title showed all interfaces). Doesn't change the fact that in either case the API doesn't return data for the description.

Thanks, I've confirmed the issue; I should have it resolved soon

One detail towards a resolution: if the vyos-http-api-server is started manually (without systemd) then the output is not truncated. If one wants to try this, one should configure 'set service https api' (to update Nginx config appropriately); then 'systemctl stop vyos-http-api'; then, as root:

[email protected]:/usr/libexec/vyos/services# ./vyos-http-api-server

So that narrows the investigation ...
