onError Macro Examples

The following examples provide an indication of how the onError macro can assist
in using and troubleshooting macro files. The examples purposely contain errors and
show the result when using the onError macro.

Detecting Invalid Command Formats

In this example, the following macro file (badInterfaceCommand.mac) performs a
loop. Within each loop, the CLI executes the interface fastEthernet command using
an invalid interface format:
If the macro were to run to completion, the CLI would execute the commands as
follows:
Because the macro uses invalid interface formats, executing the macro without the
embedded onError macro would result in error output for each loop. However, the
onError macro detects the error and stops the macro. Using the onError macro, the
output appears as follows:
host1(config)# macro testInterfaceCommand.mac badInterfaceCommandMacro
Macro 'badInterfaceCommandMacro' in file 'testInterfaceCommand.mac' starting execution (Id: 402)
See show log data.
