Considerations When Using DLUR for T2.0 or T2.1 Devices
For T2.0 or T2.1 nodes utilizing DLUR for dependent session traffic, an SSCP-PU
and an SSCP-LU session must be active in order to establish an LU-LU session.
These sessions are included in the session count for the link to the DSPU.
Therefore, if
limited resource is yes, the link will remain active as long as the
SSCP-PU session is active or LU-LU sessions are active over this link.
If you specify no for the limited resource parameter, link deactivation is controlled by
the node that initiated the connection.
If the link to the DSPU was activated due to the DSPU calling into the DLUR node
or the DLUR node calling out to the DSPU (i.e. the link station to the DSPU has
been configured in the router and
activate link automatically is yes), when the active
session count goes to zero the link is deactivated by APPN DLUR only if the DSPU
requested DACTPU. In this case, if the DLUS sends a DACTPU request to DLUR,
DLUR will deactivate the SSCP-PU session. However, it will not deactivate the link
to the DSPU. DLUR will attempt to reestablish the SSCP-PU session to the DLUS
or the backup DLUS until it is successful or until the DSPU no longer needs this
session.
If the link to the DSPU was activated by the DLUS and the session count goes to
zero, the link is deactivated by APPN DLUR only if the DLUS sends a DACTPU
request to DLUR.
The following is a dial on demand configuration example. This configuration is
similar to the ISDN permanent connection except:
v You must specify that the link is a limited resource.
v You must define the adjacent CP name.
v You must specify a TG number.
You configure both sides of the communication link the same way.
Note: If you allow CP-CP sessions on this link, the link will not disconnect.
