Recently, I was trying to reset the root password on an EX2200. Following the normal process of entering single user mode did not work. In this post I will cover the workaround to reset the root password.
On an EX2200/3200/3300/4200/4500/4550 running code version 15.1R1 - 15.1R6 password recovery via entering boot -s from the loader prompt to enter single user mode results in the switch booting from the alternate slice rather than entering single user mode.
This post has the workaround. The steps are as follows:
U-Boot 1.1.6 (Feb 6 2008 - 11:27:42) Board: EX4200-24F 2.20 EPLD: Version 6.1 (0x85) DRAM: Initializing (1024 MB) FLASH: 8 MB USB: scanning bus for devices... 2 USB Device(s) found # <<<<< Type Ctrl + C here => # remove "boot_unattended" environment variable => setenv boot_unattended # Issue "boot" command, get into "loader>" => boot # Follow the normal password reset process
In this post, I covered the process of resetting the root password on a Juniper EX switch running code version 15.1R1 - 15.1R6. Thanks @python and future Brad, you are welcome.
