NVME-CONFIG-SHOW(1) NVMe Manual NVME-CONFIG-SHOW(1)

# [NAME](#NAME)

nvme-config-show - Show the resolved NVMe-oF INI connection configuration

# [SYNOPSIS](#SYNOPSIS)

```
nvme [<global-options>] config show


                        [--config=<file> | -J <file>]
```

# [DESCRIPTION](#DESCRIPTION)

Reads the NVMe-oF INI connection configuration file used by *nvme connect-all* and *nvme discover*, and prints every configured connection entry. The INI format is documented at **https://github.com/linux-nvme/nvme-cli/blob/master/libnvme/design/CONFIG.md**

By default, the file at /usr/local/etc/nvme/nvme-fabrics.conf is read. Use --config to show a file at a different path instead.

In the default and *tabular* output formats, each entry is rendered as the equivalent command line that would establish it: *nvme connect-all* for a Discovery Controller entry, *nvme connect* for an I/O Controller entry, preceded by a comment naming the entry’s source (which file/section it came from). The *json* output format instead reports each entry’s fields individually (transport, address, NQN, host identity, and any extra connect parameters).

This command never touches the network: addressing is shown exactly as configured, with no hostname resolution attempted. A persona with no *hostnqn*/*hostid* set is shown without those fields rather than the system default it would resolve to at connect time, since showing a concrete value here would suggest a fixed identity the configuration doesn’t actually pin.

# [OPTIONS](#OPTIONS)

-J &lt;file&gt;, --config=&lt;file&gt;

Show this INI file instead of the default /usr/local/etc/nvme/nvme-fabrics.conf.

# [GLOBAL OPTIONS](#GLOBAL_OPTIONS)

The following options are defined at the top-level nvme command and are available to this subcommand:

--dry-run

Print the command that would be executed, but do not actually execute it.

--no-ioctl-probing

Disable probing for 64-bit IOCTL support.

--no-retries

Disable retry logic on transient errors.

-o &lt;fmt&gt;, --output-format=&lt;fmt&gt;

Set the reporting format to *normal*, *tabular, 'json*, or *binary*. Only one output format may be used at a time.

--output-format-version=&lt;version&gt;

Select the output format version. Version *1* uses the original field naming, while version *2* (default) provides more consistent and script-friendly field names.

--timeout=&lt;ms&gt;

Set the timeout for the command in milliseconds.

-v, --verbose

Increase the level of detail in the output. May be specified multiple times to further increase verbosity.

These options can also be set as machine-wide defaults in [nvme-cli.conf(5)](/man/os/nvme-cli/nvme-cli.conf.5). A command-line flag always overrides the file.

# [EXAMPLES](#EXAMPLES)

•Show the system’s resolved configuration:

```
# nvme config show
```

```
# nvme0: Discovery Controller
nvme connect-all --transport=tcp --traddr=192.168.1.10 --trsvcid=8009
# nvme1: I/O Controller
nvme connect --transport=tcp --traddr=192.168.1.10 --trsvcid=4420 \


        --nqn=nqn.2014-08.org.nvmexpress:uuid:6a4f5e3e-...
```

•Show a configuration file at a non-default path, as JSON:

```
$ nvme config show --config /tmp/nvme-fabrics.conf -o json
```
