Cutting Down User Connections Forcibly; Radius Configuration Task List - 3Com 4210 9-Port Configuration Manual

The following characters are not allowed in the user-name string: /:*?<>. And you cannot input
more than one "@" in the string.
After the local-user password-display-mode cipher-force command is executed, any password
will be displayed in cipher mode even though you specify to display a user password in plain text by
using the password command.
If a user name and password is required for user authentication (RADIUS authentication as well as
local authentication), the command level that a user can access after login is determined by the
privilege level of the user. For SSH users using RSA shared key for authentication, the commands
they can access are determined by the levels set on their user interfaces.
If the configured authentication method is none or password authentication, the command level
that a user can access after login is determined by the level of the user interface.
If the clients connected to a port have different authorization VLANs, only the first client passing the
MAC address authentication can be assigned with an authorization VLAN. The switch will not
assign authorization VLANs for subsequent users passing MAC address authentication. In this
case, you are recommended to connect only one MAC address authentication user or multiple
users with the same authorization VLAN to a port.
For local RADIUS authentication to take effect, the VLAN assignment mode must be set to string
after you specify authorization VLANs for local users.
