12.11 Initiate a PPP Link – PPP Command
The PPP link can be initiated in the ASG Guard/ASG Guard Plus in one of two ways. The user
can either designate a specific port as a dedicated PPP port, or you may initiate a PPP
connection on-demand.
12.11.1 Designate a Port as a PPP Port
Designate a specific port as a PPP port. After it has been designated as a PPP port, the port is
available only for a PPP connection. This ensures that a port is always available for a PPP
session. After authenticating and accessing the command prompt, issue the PPP command with
the appropriate parameters.
Command:
PPP
Syntax:
PPP active/passive flag, Host port ID
Example:
To have Host port 4 as a designated PPP port, type:
PPP A,4
Command
Function
active/passive flag
Indicates the state of the PPP link when it is initially
opened. Active links will send out broadcast packets to
initiate a PPP link. If a passive link has been established,
broadcast packets will NOT be sent out. Instead, the port
will remain in PPP mode until it receives a broadcast
packet to initiate the PPP session. Enter
A
for active link,
P
for passive link.
hostport ID
Specifies to the ASG Guard/ASG Guard Plus which port
is to become the dedicated PPP host port. Valid port ID’s
are H1, H2, H3, and H4.
At this point, the port will be available for PPP connections. When the port responds to the
incoming call, the user will be prompted to authenticate. To return the port to its normal state
(remove PPP designation), reset the port by using the RES command.
12.11.2 Initiate a PPP Connection On-Demand
The ASG Guard Plus can support a Point to Point Protocol (PPP) connection via its modem port.
ASG Guard Plus can be used as a secured gateway into a TCP/IP network by implementing the
PPP connection. This also allows the user to use TCP/IP based protocols in support of the ASG
Guard Plus. These protocols include SNMP, Telnet, and FTP.
