The Link subentity defines the local link station to the Peer Server and contains the management attributes for the operation of all supported station components. It also contains information that permits the identification of the associated X.25 server component. An instance of this subentity must exist for each X.25 communication line.
1 – create
create qllc link The create qllc link command creates an instance of the QLLC Link subentity for each local X.25 DTE address. The Link subentity is the access point into the X.25 protocol for QLLC connections to remote system. The create command also allocates resources for the subentity and sets its characteristics to their default values. Ex, ncl> create qllc link qllc-0 dte address = 12345678901
1.1 – Characteristics
Subsequent 1-8 characters Specifies an octet string that is
Protocol (hexadecimal) used to filter incoming X.25 calls
Identifier for a specific protocol. This value
corresponds to the Data Call value
in the X.25 configuration.
It is only needed to handle incoming
connections. The default value is
hexadecimal C3 (QLLC Protocol).
Filter Name Simplename Specifies the name of the Filter to
be used for incoming QLLC (X.25)
connections. This name must be
specified for links that will use
both incoming or outgoing connec-
tions. The name must also match
an X25 Access Filter that exists in
the node's X.25 configuration. The
default is filter_qllc.
Template Name Simplename Specifies the name of the Template
to be used for creating an outbound
QLLC connection. This name must
match an X25 Access Template in the
node's X.25 configuration. The
default is template_qllc.
DTE Class Simplename Specifies the name of the DTE class
to be used for creating an outbound
connection. This name must match an
X25 Access DTE Class names that
exists in the local node's X.25
configuration. The default is
class_qllc.
2 – delete
delete qllc link The delete qllc link command deletes an instance of the QLLC Link subentity and deallocates resources for the subentity. The Link subentity must be in the off state and must have no Station subentities. Ex, ncl> delete qllc link qllc-0
3 – disable
disable qllc link The disable qllc link disables an instance of the QLLC Link subentity. You can only disable a previously enabled entity. The disable command stops the operation of the Link subentity. For the disable command to be successful, all Station subentities on the Link must have been disabled. At the completion of the command the subentity is in the off entity state. Ex, ncl> disable qllc link qllc-0
4 – enable
enable qllc link The enable qllc link command places the QLLC Link subentity in its enabled state (on). Ex, ncl> enable qllc link qllc-0
5 – set
set qllc link The set qllc link command lets you set the attributes of the QLLC Link subentity. The QLLC Link subentity defines the data link attributes that are shared by its Station subentities. Ex, ncl> set qllc link qllc-0 dte address = 12345678901

Filter Name Simplename Specifies the name of the Filter to be
used for incoming QLLC (X.25) connec-
tions. This name must be specified for
links that will use both incoming or
outgoing connections. The name must
also match an X25 Access Filter that
exists in the node's X.25

DTE Class Simplename Specifies the name of the DTE class to
be used for creating an outbound
connection. This name must match an
X25 Access DTE Class names that exists
in the local node's X.25 configuration.
The default is class_qllc.
6 – show
show qllc link The show qllc link command displays the attributes for the QLLC Link subentity. The QLLC Link subentity defines the data link attributes that are shared by its Station subentities. Ex, ncl> show qllc link qllc-0 all status
6.1 – Identifier
Name Displays the name of the Link.
6.2 – Status
UID Displays the entity's unique identifier, which is
generated when the Peer Server creates the entity.
State Displays the operational state of this QLLC Link
subentity.
inoperable The Link cannot be enabled.
off You have issued a disable command for this Link.
The Link is in the Inactive or Pending Inactive
state.
on You have issued an enable command for this Link.
