Bootrom Interface
385
Skipping the Current
Configuration File
Enter boot menu option 7 to enable the Switch to boot from the factory default
configuration file
3comoscfg.def
.
When the Switch has booted from the factory default it can be configured with an
IP address and default gateway if needed.
The live configuration file (
3comoscfg.cfg
) can be added to a TFTP server and
edited.
Search through the file with a text editor until the following section is found:
#
local-user admin
password cipher ZG6-:\Y>MQGQ=^Q`MAF4<1!!
service-type telnet terminal
level 3
local-user manager
password simple manager
service-type telnet terminal
level 2
local-user monitor
password simple monitor
service-type telnet terminal
level 1
#
In the
local-user admin
section there is an entry called
password
which is
followed by either of the following entries:
■
Simple
- this enables you to read and/or change a password and send the
configuration file via TFTP back into the Switch.
■
Cipher
- change this word to
simple
and replace the encrypted password with
a plain text password and send the configuration file via TFTP back into the
Switch.
The
manager
and
monitor
passwords can be modified in the same way.
Bootrom Passwords
The bootrom can be configured with a user defined password. Select Option 5 to
display the following:
Boot menu choice: 5
Old password:
New password:xxxx
Confirm password:xxxx
Current password has been changed successfully!
If the user configured bootrom password is lost, a fixed, unit unique password can
be provided by 3Com Technical Support to bypass the lost password.
Please ensure that the Switch is registered with 3Com promptly as the unit unique
password will only be supplied to the registered owner of the Switch.
This final password recovery safeguard can be disabled.
