## Symptoms

- * When running the Gaia API command `show vlan-interfaces` on some VSX Gateways, the request fails with this non-specific error:

  `generic error 1`

  Note - Other Gaia API commands work correctly.
* The issue occurs only on some VSX nodes (not all).

* On the affected VSX nodes, the command runs for approximately 30 seconds before failing.

* The issue occurs on VSX Gateways with a large number of Virtual Local Area Network (VLAN) interfaces (for example: \~150--180+ VLAN interfaces).

* The API call is executed locally on the VSX Gateway with the Management Command Line Interface (mgmt_cli) tool using `--context gaia_api` (not through a management proxy).

## Cause

On VSX Gateways with a large number of VLAN interfaces, the `show vlan-interfaces` request requires additional time to generate the full response.

The request is terminated after approximately 30 seconds because of the default timeout values in:

* The Gaia REST API server
* The local HTTP reverse proxy (httpd2)
* The client connection timeout (`mgmt_cli`)

When the timeout threshold is reached, the request is aborted and `mgmt_cli` returns a `generic error 1`.
