Aruba release notes

Overview

NOTE: If you do not have Aruba 8325 switches in your system, skip this stage and return to main upgrade page.

You can run the NAE script on the 8325 platform switches to resolve a MAC learning issue. An install script is provided to automate this process.

The file locations:

Prerequisites

  • You have an 8325 in your setup that is running software version below 10.06.0130.
  • Additionally, the install script used in this procedure makes the following assumptions:
    • The switches (and their IP addresses) are in the /etc/hosts file with hostnames containing the string “sw”.
    • You are using default username admin for the switches.
    • All of the switches use the same password for the admin user (the install script will prompt you for the password).

Procedure

IMPORTANT:

Reminder: Before running any upgrade scripts, be sure the Cray CLI output format is reset to default by running the following command:

ncn# unset CRAY_FORMAT

  1. Run the NAE install script:

    ncn-m002# /usr/share/doc/csm/upgrade/1.0.1/scripts/aruba/nae_upload.py

  2. Type in your switch password and the script will upload and enable the NAE script.
