Network Tests

The CSM Automatic Network Utility (CANU) has the ability to run tests against the management network.

If doing a CSM install or upgrade, a CANU RPM is located in the release tarball. For more information, refer to the Update CANU From CSM Tarball procedure.

The switch inventory is dynamically created from either a System Layout Service (SLS) file --sls-file, or it will automatically query the SLS API if an SLS file is not specified.

Prerequisites

SSH access to the switches
SLS file or SLS API access
CANU has to be on version 1.1.4 or later; run canu --version to verify

Examples

(ncn#) Pulling switch inventory from SLS and logging to screen, this requires the API gateway to be up.
```
canu test --log
```
(ncn#) Pulling switch inventory from SLS file and connecting to the switches via their CMN IP addresses, this can be done outside the Shasta cluster.
```
canu test --sls-file ../Hela/sls_input_file.json --network CMN
```
(ncn#) Pulling switch inventory from SLS and having the output be in JSON format.
```
canu test --json
```

Running the tests can take some time if there are a lot of management switches.

The output will look similar to the following:
