Configuring Username and Password Security
Front-Panel Security
Figure 2-11. Example of the Steps for Disabling Password-Recovery
Password Recovery Process
If you have lost the switch’s manager username/password, but
password-
recovery
is enabled, then you can use the Password Recovery Process to gain
management access to the switch with an alternate password supplied by
ProCurve.
N o t e
If you have disabled
password-recovery
, which locks out the ability to recover
a manager username/password pair on the switch, then the only way to
recover from a lost manager username/password pair is to use the
Reset+Clear button combination described under “Restoring the Factory
Default Configuration” on page 2-11. This can disrupt network operation and
make it necessary to temporarily disconnect the switch from the network to
prevent unauthorized access and other problems while it is being reconfig­
ured.
To use the
password-recovery
option to recover a lost password:
1. Note the switch’s base MAC address. It is shown on the label located on
the upper right front corner of the switch.
2. Contact your ProCurve Customer Care Center for further assistance.
Using the switch’s MAC address, the ProCurve Customer Care Center will
generate and provide a “one-time use” alternate password you can use
with the to gain management access to the switch. Once you gain access,
you can configure a new, known password.
N o t e
The alternate password provided by the ProCurve Customer Care Center is
valid only for a single login attempt. You cannot use the
same “one-time-use”
password if you lose the password a second time. Because the password
algorithm is randomized based upon your switch's MAC address, the pass-
word will change as soon as you use the
“one-time-use” password provided
to you by the ProCurve Customer Care Center.
