# Consul Troubleshoot Upstreams
|
||
|
|
|
||
|
|
Command: `consul troubleshoot ports`
|
||
|
|
|
||
|
|
The `troubleshoot ports` prints TCP port statuses to help you troubleshoot port connectivity.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
Usage: `consul troubleshoot ports [options]`
|
||
|
|
|
||
|
|
#### Command Options
|
||
|
|
|
||
|
|
- `-host=<value>` - Host name to troubleshoot TCP ports for. You can also set the `CONSUL_HTTP_ADDR` environment variable instead of using the `-host` flag.
|
||
|
|
- `-ports=<value>` - Specifies a comma-separated list of custom ports to check.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
The following example checks the default ports Consul server uses for TCP connectivity. Note that the `CONSUL_HTTP_ADDR` environment variable is set to `localhost`. As a result, the `-host` flag is not required.
|
||
|
|
Refer to [Required Ports](/consul/docs/install/ports) for additional information.
|
||
|
|
|
||
|
|
```shell-session
|
||
|
|
$ export CONSUL_HTTP_ADDR=localhost
|
||
|
|
$ consul troubleshoot ports
|
||
|
|
TCP: Port 8501 on localhost is open.
|
||
|
|
TCP: Port 8502 on localhost is open.
|
||
|
|
TCP: Port 8503 on localhost is open.
|
||
|
|
TCP: Port 8302 on localhost is open.
|
||
|
|
TCP: Port 8300 on localhost is open.
|
||
|
|
TCP: Port 8600 on localhost is open.
|
||
|
|
TCP: Port 8301 on localhost is open.
|
||
|
|
TCP: Port 8500 on localhost is open.
|
||
|
|
```
|
||
|
|
|
||
|
|
The following example checks TCP ports status on the `hashicorp.com` host.
|
||
|
|
|
||
|
|
```shell-session
|
||
|
|
$ consul troubleshoot ports -host hashicorp.com -ports 80,8077
|
||
|
|
TCP: Port 80 on hashicorp.com is open.
|
||
|
|
TCP: Port 8077 on hashicorp.com is closed, unreachable, or the connection timed out.
|
||
|
|
```
