dlur
Use the dlur TN3270 configuration command to enable the Systems Network Architecture (SNA)
session switch function on the CIP, or to enter dependent logical unit requester (DLUR)
configuration mode. Use the no form of this command to disable the SNA session switch function
and discard all parameter values associated with the SNA session switch.

Syntax Description
Default
No DLUR function is enabled.
Command Mode
TN3270 configuration
Usage Guidelines
If the SNA session switch function is already enabled, the dlur command with no arguments puts
you in DLUR configuration mode.
Several parameters in the DLUR configuration mode consist of fully qualified names, as defined by
the APPN architecture. Fully qualified names consist of two case-insensitive alphanumeric strings,
separated by a period. However, for compatibility with existing APPN products, including VTAM,
the characters “#”(pound), “@” (at), and “$”(dollar) are allowed inthe fully qualified name strings.
Each string is from one to eight characters long; for example, RA12.NODM1PP. The portion of the
name before the period is the NETID and is shared between entities in the same logical network.
The no dlur command hierarchically deletes all resources defined beneath it.
Example
The followingcommand performstwo functions:It entersDLUR configurationmode; andit enables
the DLUR functionand defines theLU name for theDLUR as SYD.TN3020 andthe primary choice
for DLUS as SYD.VMG. Note that the NETID portion of both names is the same:
dlur SYD.TN3020 SYD.VMG
fq-cpname Fully qualified control point (CP) name used by the SNA
session switch and the logical unit (LU) name for the
DLUR function. This name must be unique among APPN
nodes in the network including other fq-cpname values
specified on all other TN3270 servers running under the
Cisco IOS software.
fq-dlusname Fully qualified name of the primary choice for the
dependent LU server (DLUS). This is the name of an LU,
usually a CP, in an APPN host. The fq-dlusname value can
be repeated and shared across servers.
