Command Reference Guide

Administration Commands
query_downstream_lu
Start at the entry immediately following the entry specified by the combination of the dspu_name and
dslu_name parameters
dslu_name
Name of the LU for which information is required, or the name to be used as an index into the list of LUs.
This value is ignored if list_options is set to
FIRST_IN_LIST. The name is a type-A character string.
dspu_name
PU name for which LU information is required, as specified in the definition of an LS. To list only information
about LUs associated with a specific PU, specify the PU name. To obtain a complete list for all PUs, do not
specify this parameter.
dspu_services
DSPU services filter. When the query_downstream_lu command is issued to a running node, this
parameter specifies whether to filter the returned information by the type of services provided to the LUs.
Possible values are:
PU_CONCENTRATION
Return information only about downstream LUs served by PU concentration.
DLUR
Return information only about downstream LUs served by DLUR.
NONE
Return information about all downstream LUs.
When the node is not running, this parameter is ignored; SNAplus2 returns information about all downstream
LUs.
2.128.2 Returned Parameters: Summary Information
Parameter name Type Length
dslu_name character 8
dspu_name character 8
description character 31
dspu_services constant
nau_address decimal
lu_sscp_sess_active constant
plu_sess_active constant
If the command executes successfully and you specified SUMMARY as the list_options parameter value, SNAplus2
returns the following parameters:
dslu_name
Name of the downstream LU.
dspu_name
Name of the PU associated with the downstream LU.
description
For an LU supported by PU concentration, this parameter is a text string describing the downstream LU, as
specified in the definition of the downstream LU. For a DLUR-supported LU, this parameter is reserved.
dspu_services
When the query_downstream_lu command is issued to a running node, this parameter specifies the
services provided by the local node to the downstream LU.
