In my last post, I have discussed in accessing the Extended BootROM of the HP Comware network device. In order to perform password recovery, we need to access the Extended BootROM menu by pressing CTRL+B and selecting the option to skip the current system (or startup) configuration. (Note: This is done thru the console port of the network device)
This post will discuss Password Recovery method for HP Comware network devices. This password recovery procedure was tested on HP 5120 48-Port Network Switch with BootROM version 171 (released February 24, 2015).

This post is in continuation of the previous post on HP Comware BootROM. In this article, I will display the menu options for the Extended BootROM for a HP 5120 Network Switch. This mode can be accessed by pressing CTRL+B while the device is booting and this keypress option is displayed (see below).
This post will highlight accessing the boot loader of an HP Comware network device. This is called BootROM in most HP Comware devices (or BootWare in the H3C models). This post will show accessing the bootloader (BootROM) for an HP 5120 Switch. The HP 5120 Switch has two modes in accessing the BootROM. First mode is the Basic Boot Mode which can be accessed by pressing CTRL+D while the device is booting. Note that this can only be performed while accessing the network device through the Serial Console. Starting...... The Basic BootROM menu provides limited options in updating the BootROM software for both basic and extended upgrades. The Menu display might be different for other BootROM versions. In most options, it requires selecting the baudrate prior to downloading the BootROM software via XMODEM protocol.
In summary, HP Comware supports local logfile. This means logs generated by the network device can be stored in a local file within the device. This feature is very convenient in case the network devices encounters a disruption (i.e. power, hardware fault) and its logs are not able to reach the configured SYSLOG host. The locally stored logs will be useful in conducting post mortem network analysis (i.e. before the network device rebooted). HP Comware local logfile is disabled by default.
