When you update software from a version that does not support long passwords to a version that supports long passwords, the existing user names and passwords continue to be there and no further action is required.
Before downgrading to a software version that does not include this feature, use one of the following procedures:
Procedure
-
Reset the user name and/or password to be no more than 16 characters in length, without using any special characters, from the CLI command
password
.
- Execute a CLI
write memory
command (required if the
include-credentials
feature has ever been enabled.)
switch(config)# password manager
New password: ********
Please retype new password: *******
switch(config)# write mem
-
Or
-
Execute the CLI command
no password all
. This clears all the passwords.
- Execute a CLI
write memory
command (required if the
include-credentials
feature has ever been enabled.)
switch(config)# no password all
Password protections will be deleted, do you want to
continue [y/n]? y
switch(config)# write mem
-
Or
-
Clear the password by using the
[Clear] button on the switch.
- Execute a CLI
write memory
command (required if the
include-credentials
feature has ever been enabled.)
