20 TN3270 Server Commands
dlur
dlur
Use thedlur 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 theno form of this command to disable the SNA session switch function
and discard all parameter values associated with the SNA session switch.
dlur
dlur fq-cpname fq-dlusname
nodlur
Syntax Description
Default
No DLUR function is enabled.
Command Mode
TN3270 configuration
Usage Guidelines
If the SNA session switch function is already enabled, thedlur command with no arguments puts
you in DLUR configuration mode.
Severalparameters in the DLUR configuration mode consist of fully qualified names, as defined by
theAPPN architecture. Fully qualified names consist of two case-insensitive alphanumeric strings,
separatedby a period. However, for compatibility with existing APPN products, including VTAM,
thecharacters “#” (pound), “@” (at), and “$” (dollar) are allowed in the fully qualified name strings.
Eachstring 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.
Theno dlur command hierarchically deletes all resources defined beneath it.
Example
Thefollowing command performs two functions: It enters DLUR configuration mode; and it enables
theDLUR function and defines the LU name for the DLUR as SYD.TN3020 and the 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 otherfq-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. Thefq-dlusname value can
be repeated and shared across servers.
