ipv6 ipv6-address: Specifies the IPv6 address of a user.
Usage guidelines
If you do not specify any parameters, this command displays information about all users in the
password control blacklist.
The users' IP addresses and user accounts are added to the password control blacklist when the
users fail authentication. You can use this command to view information about blacklisted FTP, Web,
and virtual terminal line (VTY) users.
Users accessing the system through the console or AUX interface are not blacklisted for the
following reasons:
• The system is unable to obtain the IP addresses of these users.
• These users are privileged and, therefore, relatively secure to the system.
