5.1.21 re-authentication
Syntax
re-authentication
undo re-authentication
View

Parameter
None
Description
Use the re-authentication command to enable console login re-authentication.
Use the undo re-authentication command to disable console login re-authentication.
By default, console login re-authentication is disabled.
Console login re-authentication can provide extra security for your console connection
based on console login authentication.
Suppose you remove the console cable without clearing the existing console
connection. Console login re-authentication ensures that even if the cable is connected
again when the console connection is still present, one must undergo another
authentication to log in from the console port.
Configure the re-authentication command in conjunction with the flow-control
hardware command.
Example
# Enable console login re-authentication.
[3com] user-interface console 0
[3com-ui-console0] re-authentication
[3com-ui-console0] flow-control hardware
# Configure password authentication on the console port.
