# Consul Intention Check
|
|
|
|
|
|
|
|
Command: `consul intention check`
|
|
|
|
|
|
|
|
The `intention check` command checks whether a connection attempt between
|
|
|
|
two services would be authorized given the current set of intentions and
|
|
|
|
Consul configuration.
|
|
|
|
|
|
|
|
This command requires less ACL permissions than other intention-related
|
|
|
|
tasks because no information about the intention is revealed. Therefore,
|
|
|
|
callers only need to have `service:read` access for the destination. Richer

|
commands like [match](/commands/intention/match) require full

|
|
|
intention read permissions and don't evaluate the result.
|
|
|
|
|
2020-10-14 15:23:05 +00:00
|
|
|
-> **Note:** This command will always treat intentions with `Permissions`
|
2020-12-08 23:24:36 +00:00
|
|
|
defined as _deny_ intentions during evaluation, as this endpoint is only suited
|
2020-10-14 15:23:05 +00:00
|
|
|
for networking layer 4 (e.g. TCP) integration.
