set to any output generated by the script. Similarly, an external process updating
a TTL check via the HTTP interface can set the `notes` value.
Checks may also contain a `token` field to provide an ACL token. This token is
used for any interaction with the catalog for the check, including
[anti-entropy syncs](/docs/internals/anti-entropy.html) and deregistration.
To configure a check, either provide it as a `-config-file` option to the
agent or place it inside the `-config-dir` of the agent. The file must
end in the ".json" extension to be loaded by Consul. Check definitions can

## Services and Checks with ACLs
Consul allows configuring ACL policies which may control access to service and
check registration. In order to successfully register a service or check with
these types of policies in place, a token with sufficient privileges must be
provided to perform the registration into the global catalog. Consul also
performs periodic [anti-entropy](/docs/internals/anti-entropy.html) syncs, which
may require an ACL token to complete. To accommodate this, Consul provides two
methods of configuring ACL tokens to use for registration events:
1. Using the [acl_token](/docs/agent/options.html#acl_token) configuration
directive. This allows a single token to be configured globally and used
during all service and check registration operations.
2. Providing an ACL token with service and check definitions at
registration time. This allows for greater flexibility and enables the use
of multiple tokens on the same agent. Examples of what this looks like are
available for both [services](/docs/agent/services.html) and
[checks](/docs/agent/checks.html). Tokens may also be passed to the
[HTTP API](/docs/agent/http.html) for operations that require them.
