Enabling automatic MID Server selection lets the agent perform a connectivity test against the list of available MID Servers and determine the best connection based on latency and number of currently connected agents. Automatic MID Server selection is disabled by default.

## Before you begin

Role required: agent_client_collector_admin

## Procedure

* To enable sending periodic MID Server updates from the ServiceNow instance to existing agents, set the sn_agent.enable_auto_mid_selection system property to true.
* To enable automatic MID Server selection for individual agents:  
  1. Set the enable-auto-mid-selection property in the agent's acc.yml file to true.
  2. Enable and execute the Update MID List for All Agents and Update MID List for All New Agents scheduled jobs.

{#acc-disable-auto-mid-selection__steps-unordered_bkg_f3q_spb}

## What to do next

To disable automatic MID Server selection again, set each of the properties back to false.

To schedule updates more often than once daily, or execute the job on demand, see [Configure the frequency of updating the agent MID Server list](https://servicenow-prod.fluidtopics.net/9HpnCsIxsYowUwjWrM9Qrw "By default, the list of MID servers connected to agents is updated once daily. If you have a dynamic environment that adds MID servers frequently, you may want to schedule updates more often, or execute the job on demand.").
