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

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:
