In an effort to bring customers a best of breed solution Tangent
has partnered with Extreme Networks. Links to additional information
about Extreme can be found on our Extreme
Networks product pages. We will explore Extreme Networks
products in more detail in subsequent articles, but for now
I would like to start off with a simple password recovery procedure.
There are many reasons for lost passwords from personnel changes
to used equipment purchases. This document will walk you through
recovery step by step. All procedures in this document require
physical access to the switch for security reasons. This procedure
works on all Black Diamond's with bootrom version 3.7 or higher,
Summit's with bootrom version 1.9 or higher, and any "i" series
products. The test in this article was performed on an Alpine
3808. The basic procedure is the same for all the Extreme switches
although the actual commands may differ over the entire product
line. If your Extreme switch recovery process does not resemble
the one shown here then your other option is to call Extreme.
They will be able to perform the recovery remotely with the
use of a modem. As I have said, this is necessary for certain
older versions of bootroms.
The first step for recovery of your Extreme password is to set
up your terminal emulation settings. A terminal emulation program
such as Hilgraeve's Hyperterminal, www.hilgraeve.com,
or various others allow you to connect to the console port on
the Extreme switch. Console settings are 9600 bits per second,
8 data bits, no parity, one stop bit and no flow control. Once
you are able to establish a command line interface with the
Extreme switch, you are ready to perform the second step, a
hard reboot.
A hard reboot consists of unplugging the unit and plugging it
back in. A soft reboot, in this case typing reboot at the command
line interface, will not suffice as a complete cycling of the
power is needed. While plugging the switch back in hold down
the space bar until the bootrom menu appears. At the Bootrom->
prompt enter an h, for help.
This will bring up the menu. The menu should appear as seen
below
1: Select primary code image
2: Select secondary code image
3: Select primary configuration
4: Select secondary configuration
b: Change baud rate
d: Force default configuration
f: Boot on board flash
h: Help
k: Erase selected configuration
p: Boot PCMCIA cards:
s: Load code image from serial port using XMODEM
The option you want to choose is to select the primary code
image by hitting 1. After the
primary image is selected select k
to erase selected configuration. If you are trying to restore
a unit to factory defaults then proceed the same way, erasing
the secondary configuration. After this has been completed,
there should be no more passwords of any kind on your Extreme
switch. Choose d to force default
configuration and then f to boot
on board flash. After your Extreme switch resets and you are
prompted with a login enter in admin,
hit enter twice entering a blank password at the password prompt.
You should now have admin level access. Change your login and
password, saving them when you are finished.
This has been a short tutorial on password recovery for your
Extreme switch. Please stay tuned for more publications in the
future.
