Introduction
The Digi CM provides several ways to control access to the network and the
devices on the network. One method for controlling access is through IP
filtering which allows or prevents users from specific IP addresses from
accessing devices or serial ports on the network. IP filtering can be permitted
or restricted for all ports globally or on a per port basis. Another method of
controlling access is by restricting or permitting specific users. Users can be
easily added or removed from either a restricted or permitted users list. Sniff
session access is also discussed.
The Digi CM provides for various authentication methods. The four methods
are: Local, RADIUS, TACACS+, and LDAP. Authentication may be configured
where a secondary method is attempted if the primary method fails.

Configuring Network IP Filtering

Access to the Digi CM can be controlled through IP filtering. IP filtering
controls access to the Digi CM from remote hosts either trying to access from
a remote console or a web browser. IP filtering can also be used to control
access to individual ports.
