This device uses CHAP (Challenge-Handshake Authentication Protocol) when authenticating users with the
server. To use a server, do the following:
1.
Open an account for a user on the server.
2.
On that server, configure the user or group privileges to
1
for an Audit user,
2
for an Operator, or
3
for an
Administrator. For example, privilege level
2
is given to a user or group of users on the server by the
following string in the user or group definition:
service = exec
{ priv-lvl = 2
}
3.
Specify as the authentication method, so that when a user logs onto the device, authentication is performed
on the server instead of locally.
Note:
If more than one server has been configured, the device uses the configured priorities of
the available servers to select the server to be used by the device. As shown in the
following figure, server priority can be changed by dragging the servers into the required order. Servers at the
top of the list have the highest priority.
