Management Network User Guide

This documentation helps network administrators and support personnel install install and manage Aruba, Dell, and Mellanox network devices in a CSM install.

The HPE Cray recommended way of configuring the network is by using the CANU tool. Therefore this guide will not go into detail on how to configure each switch manually using the CLI. Instead, it will give helpful examples of how to configure/use features generated by CANU, in order to provide administrators easy ways to customize their installation.

Also included in this guide are the current documented and supported network scenarios.

NOTE Not every configuration option is covered here; for any configuration outside of the scope of this document, refer to the official Aruba, Dell, or Mellanox user manuals.

This document is intended for network administrators and support personnel.

NOTE The display and command lines illustrated in this document are examples and might not exactly match any particular environment. The switch and accessory drawings in this document are for illustration only, and may not exactly match installed products.

Adding switch admin password to Vault

If CSM has been installed and Vault is running, add the switch credentials into Vault. Certain tests, including goss-switch-bgp-neighbor-aruba-or-mellanox use these credentials to test the state of the switch. This step is not required to configure the management network. If Vault is unavailable, this step can be temporarily skipped. Any automated tests that depend on the switch credentials being in Vault will fail until they are added.

(ncn-mw#) The following script will prompt for the password, write it to Vault, and then read it back to verify that it was written correctly.

/usr/share/doc/csm/scripts/operations/configuration/write_sw_admin_pw_to_vault.py

On success, the script will exit with return code 0 and have the following final lines of output:

Writing switch admin password to Vault
Password read from Vault matches what was written
SUCCESS

Security Bulletin subscription service

To initiate a subscription to receive future HPE Security Bulletin alerts via email, see the HPE Support Center.

A Security Bulletin is the published notification of security vulnerabilities and is the only communication vehicle for security vulnerabilities.

  • Fixes for security vulnerabilities are not documented in manuals, release notes, or other forms of product documentation.
  • A Security Bulletin is released when all vulnerable products still in support life have publicly available images that contain the fix for the security vulnerability.
