Configuring Username and Password Security
Configuring Local Password Security
Additional Restrictions
Some authentication servers prevent the usage of special symbols such as the
backslash (\) and quotes (“”). The switch allows the use of these symbols in
configurable credentials, but using them may limit access for some users who
may use different client software. Please refer to the vendor’s documentation
for specific information about these restrictions.
Operating Notes on Upgrading or Downgrading Software Versions
When you update software from a version that does not support long pass-
words to a version that supports long passwords, the existing usernames and
passwords continue to be there; no further action is required.
Before downgrading to a software version that does not include this feature,
use one of the following procedures:
1. Reset the username and/or password to be no more than 16 characters
in length, and without any special characters, using the CLI command
password or the equivalent in the WebAgent. Then execute a CLI write
memory command (required if the include-credentials feature has ever
been enabled).
HP Switch(config)# password manager
New password: ********
Please retype new password: *******
HP Switch(config)# write mem
Or
2. Execute the CLI command
no password all
. This clears all the passwords.
Then execute a CLI
write memory
command (required if the
include-
credentials
feature has ever been enabled).
HP Switch(config)# no password all
Password protections will be deleted, do you want
to continue [y/n]? y
HP Switch(config)# write mem
Or
3. Clear the password by using the "Clear" button on the switch. Then
execute a CLI
write memory command (required if the include-credentials
feature has ever been enabled).
