2. Using the Command Line Interface4200-A2-GB20-00 August 2002 2-3ParametersParameters are values which clarify the function of a command. Parameter syntaxmust be followed exactly to avoid system error responses. There are two types ofparameters: Staging parameters − Designate where the verb of the command conductsits operation (address). There are three unique addressing parameters:— Target IDentification (TID) − Identifies the Network Element (NE) to whichthe command is directed. Each NE in the system should have its own TIDcode.— Access IDentification (AID) − Gives the location of the network entity (suchas specific facilities and equipment) to which the command is directed.When accessing multiple records, grouping and ranging of parametersmay be allowed. An example if grouping is in the commandRTRV-EQPT::LT-1-1-4<-1-1-5<-1-1-6; where units -4, -5,and -6 are requested. Note that the group must be specified for each itementered. An example of ranging is in the commandRTRV-EQPT::LT-1-1-4&&-6; where -4&&-6 requests units 4 through6. The ampersand (&) separates descriptive records, groups, andmembers within an AID.— Correlation TAG (CTAG) − Correlates the response message to the inputcommand. A response to a command echoes the appropriate CTAG. Thisfield is optional and can be any valid value or blank. The CLI automaticallyfills in 100 (seeCommand Entry Features on page 2-4). Data parameters − Provide specific data that may either be required oroptional. For example, in the command SET-DAT, the date and time are dataparameters (see SET-DAT in Chapter 14,System Commands for moreinformation).Output MessagesOutput messages are either the result of an input command or an event thatoccurred in an NE, or are autonomous. The response message can be eithernormal or an error report (see Appendix A,Error Codes). Those messages thatare not a response to an input command are classified as autonomous.
