Note
In most cases, the SAP indicated will be F8 hex because these commands are generally between Node Manager software operating on different nodes. (Recall that Node Manager software posts its class number on SAP F8.) How" ever, there are special cases where the LANIC card firmware responds (Medium Access Control sublayer) corresponding to SAP 00, or there may be special user software developed on other SAPs.
Node Manager Commands
In the remainder of this section, the available Node Manager commands are described. The commands are categorized by the type of service provided (Configuration, Diagnostics, Event Logging, and Statistics) and discussed in the sequence that they appear in the MENU file (the Help Facility) as shown in Appendix B.
Caution Before issuing Node Manager commands on an active network, the impact on various hardware and software operations should be well understood. This will help to prevent unexpected node or network failure. Although command results are normally reversible, it is recommended that offline systems be used during the Node Manager software familiarization process.
Note
Node Manager commands are directed to a target node specified by its Station Address as a command parameter (ADR). Node Manager commands cannot be sent to target nodes using Multicast or Broadcast addresses. Such attempts will result in a command entry error.
When commands are entered, various parameters may be defaulted. Where convenient, parameter defaults are specified in the discussion of each command.
However, there are three command parameters that warrant special consideration here. They are common to several commands and their defaults are interdependent. These parameters are:
