This guide was written with the Aruba S2500 switch, though it should be mostly applicable to other similar models
When obtaining a new piece of used network equipment, the best method first is to clear the configuration of the device, to start with a clean slate.
Connect to the serial console port on the switch. This will allow you to manage the switch. On the front LCD menu, select “Maintenance” then “Factory Reset”. Accept the confirmations which follow.
From here, the connected serial console will begin to show you the steps of the factory reset. Wait until the system boots again. It will take roughly 3-5 minutes.
While it’s booting, you will see the ArubaOS version number scroll by (example below). This may be useful for future debugging and searching, so you may want to write it down.
ArubaOS Version 126.96.36.199 (build 54199 / label #54199)
After the factory reset complets, the serial console will print :
Log in with the default username and password of
forgetme! is used to complete the reset.
User: password Password: *********
Set Username and Password
To begin setup, run
enable with password
enable to use elevated privileges.
(ArubaS2500-48T) >enable Password:****** (ArubaS2500-48T) #configure terminal Enter Configuration commands, one per line. End with CNTL/Z
Now, set the username and password with
mgmt-user admin root
(ArubaS2500-48T) (config) #mgmt-user admin root Password:
Type “exit[enter]” three times to exit configure mode, enable mode, and the main shell. This will return you to the login prompt.
Now, log in with your new account: “admin” -> your password you selected.
(ArubaS2500-48T) User: admin Password: *************** (ArubaS2500-48T) >
If you see the
(...) > prompt, you are now logged in with your new login account.
Next, we need to set the ‘enable’ password.
Log in with command
enable and password `enable, and run “enable secret”.
(ArubaS2500-48T) >enable Password:****** (ArubaS2500-48T) #configure terminal Enter Configuration commands, one per line. End with CNTL/Z (ArubaS2500-48T) (config) #enable secret Password:
Finally, write the terminal config with
write memory to store the running config
to the memory to be used on boot.
Your user and enable password are now configured.
Next, set up your basic options:
(ArubaS2500-48T) #configure terminal Enter Configuration commands, one per line. End with CNTL/Z
Once in configuration mode, enter the following commands (adjusting values as needed) to provide the switch basic configuration.
hostname "switch.hostname.example.com" ip name-server 188.8.131.52 clock timezone "CST" -6 0 write memory
Back up config
Finally, you want to backup your configuration - otherwise if there are any issues, you’ll need to rebuild the entire config.
Minimally, you can print the configuration to the console using
Or, to back up the entire configuration, run
backup flash. This will write the current
configuration to “flashbackup.tar.gz.” When the write finishes, confirm the timestamp
looks correct with command
Once the file is there, you can use tftp to copy the config off the device:
copy flash: flashbackup.tar.gz tftp: <tftp-server-ip-address> flashbackup.tar.gz
