Description
both - (the default) firstly with the unit's own user table. If
the username is found in unit but the password is incorrect,
an authentication request is sent to the RADIUS host. If the
username is not found in the unit, authentication is passed up
to the RADIUS host. (The exception is the 'admin' user; if
you supply an incorrect password, the unit will not go to the
RADIUS host; it will fail the authentication).
When the unit uses the RADIUS host, it will try firstly the
primary RADIUS host and then - if one is specified - the
secondary RADIUS host; (see
page 51).
local - with the unit's user table (only)
RADIUS - with the RADIUS host's user table (only); does
not apply to username 'admin' who is always authenticated
locally.
You can use the auto configuration method for configuring
the Console Server from a DHCP server. You must turn on
this feature by selecting 'on' and disable this feature by
selecting 'off'. Default is 'off' or DHCP is disabled.
In order to provide a secure connection from the LAN to a
device on the Console Server, you must enable the
appropriate SSH protocol version. By default, ssh protocol is
'disabled'. To support SSH version 1, select 'ssh-1'. To
support SSH version 2 only, select 'ssh-2'. To enable both
version of ssh support, select 'both (ssh-1+ssh-2)'. If you are
configuring ssh for the first time, you will be prompted to
generate the appropriate encryption keys used for negotiating
a secure connection. This key generation process could take
several minutes. Once generated, the Console Server will
then support the ssh protocol selected.
