The cug=[+|-]<CUG_num> option allows the inclusion or deletion of a Closed User
Group in the list of CUGs assigned to the user port. The “+” will add the <CUG_num> to
the CUG list. The “-” is used to delete the <CUG_num> from the list.
The crfix=< TRANS | NONULL > option accommodates an anomaly in some early
variants of telnet implementation on UNIX systems, which insert a NULL character in the
data stream after a carriage return. Most end devices are not affected by this NULL
character. However, some devices (e.g. the BNS control computer) have erroneous
operation if these characters are received. The value TRANS indicates transparent
operation, where all data received by the xxxx, including a NULL after a carriage return,
is forwarded to the end device. The value of NONULL removes a NULL character
immediately following a carriage return. No other NULL characters are affected. The
default operation is transparent, and the crfix option may only be specified if the protocol
selected is asynchronous.
The crlf=< TRANS | NOLF > option is used to strip LF (line-feed) after CR (carriage
return) in the asynchronous protocol.
The PDDonCR=< ON | OFF > option is used in conjunction with the DEST, and DPORT
options to define a permanent destination which is not automatically dialed. The xxxx
will display a message that the user should enter a “carriage return”. Once entered, the
permanent destination is defined. This option is used for a secure connection via a
network security server. Please note that making the port permanently active with the
PAP command will over-ride this feature.
The crypt=< ON | OFF > option is used to select peer to peer secure cryptography of
the session. Both session endpoints should be set identically. When the feature is set
OFF, there is no cryptography on the session. When the feature is set ON, a peer to
peer session cryptography is used. The key selection is dynamic, and automatically
performed by the xxxx.
The comment=”User Comment” option allows the administrator to post a note related
to the user port. The string is double quoted, and may have any length up to sixteen
characters between the quotes. Per Port comments can be changed even if the user
ports are "in service".
The moveto=<New Port Number> option allows the administrator to move this
configured port to another port number without re-entering the configuration. The original
port number configuration is then deleted.
The copyto=<Port Number Range> option allows the administrator to replicate this port
exactly on other ports. The <Port Number Range> may cross the port being replicated.
The
x25dxe=<DTE | DCE> option is available only when the port is of type x25. It allows
changing the logical sex of the interface. Each X.25 interface needs a single DTE and a
single DCE. Normally, the network side is the DCE. For some network elements, the
converse is true. An example is the LTS, and a #5ESS IOP.
