# nvme-config-show(1)

Show the resolved NVMe-oF INI connection configuration

## NAME

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

## SYNOPSIS

```
nvme [<global-options>] config show
                        [--config=<file> | -J <file>]
```

## 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

- \-J \<file\>, --config=\<file\>

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

## 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 \<fmt\>, --output-format=\<fmt\>

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

- \--output-format-version=\<version\>

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

- \--quiet

  Suppress informational messages. Errors are still reported, and --quiet cancels any --verbose for the library log level.

- \--set-options=\<key=value\>\[,\<key=value\>...\]

  Set libnvme library options for this invocation. Supported keys are *force-4k*, *mi-probe-enabled*, *test-base-dir* and *test-sysfs-dir*.

- \--timeout=\<ms\>

  Set the timeout for the command in milliseconds. *infinite* or *-1* waits without a time limit (0xffffffff).

- \-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)](/nvme-cli.conf/5.md). A command-line flag always overrides the file.

## 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
```
