Retrieving the ADR Parameter

When the command parameters are defaulted, Node Manager software (specifically, the NM2 module) will insert the necessary values into the command string. Following the default rules of Table 5"1 and Table 5"2, an attempt is made to read the Station Address from the applicable LANIC card for use as the ADR parameter.

However, in some cases this address may not be accessible (for example, the card may not respond). If a value cannot be retrieved, the NM2 module will enter the address

00-00-00-00-00-00

(the •default" of ADR defaults), and in a normal manner, pass the command to the NMGR module for processing.

In such cases, the message:

The card address could not be acquired. Try card self-test with TC,,LU#.

is returned, along with other information pertinent to the particular command. The TC command is used to initiate card self"test. Since it is a local card, its LU# parameter may be specified and an indication of the problem may be returned (see the TC command description later in this chapter).

Configuration Commands

For both local and remote nodes, certain Node Manager commands can be used to determine the present settings of various node parameters, or to modify these settings as required. Commands are interactively entered; for parameters to be modified, changes are made without stopping system operation.

Node Manager configuration commands are listed below. Command parameters are specified in the command descriptions that follow.

DRead Link Configuration, RC

DSet Link Configuration, SC

DUpdate Link Configuration, UC

DInsert Multicast Address, IM

DDelete Multicast Address, DM

DCreate Link File Directories, CD

DPurge Link File Directories, PD

DCheck Link File Existence, CK
