Example:
Device# configure terminal
Step 13 event manager directory user { library path | policy path }
Specifies a directory to use for storing user library files or user-defined EEM policies. In the following example, the
user_library directory on disk0 is specified as the directory for storing user library files.
Specifies a directory to use for storing user library files or user-defined EEM policies. In the following example, the
user_library directory on bootflash is specified as the directory for storing user library files.
Example:
Device(config)# event manager directory user library disk0:/user_library
Device(config)# event manager directory user library bootflash:/user_library
Step 14
event manager policy policy-filename
[
type
{
system
|
user
}] [
trap
]
Registers the EEM policy to be run when the specified event defined within the policy occurs. In the following example,
the new EEM policy named cl_mytest.tcl is registered as a user-defined policy.
Example:
Device(config)# event manager policy cl_mytest.tcl type user
Step 15
Cause the policy to execute, and observe the policy.
To test that the policy runs, generate the conditions that will cause the policy to execute and observe that the policy runs
as expected.
Step 16
Use debugging techniques if the policy does not execute correctly.
Use the Cisco IOS
debug event manager CLI command with its various keywords to debug issues. Refer to the
Troubleshooting Tips, on page 1795 for details about using Tcl-specific keywords.
Troubleshooting Tips
• Use the debug event manager tcl commands CLI command to debug issues with Tcl extension
commands. When enabled, this command displays all data that is passed in and read back from the TTY
session that handles the CLI interactions. This data helps ensure users that the commands they are passing
to the CLI are valid.
• The CLI library allows users to run CLI commands and obtain the output of commands in Tcl. Use the
debug event manager tcl cli-library CLI command to debug issues with the CLI library.
• The SMTP library allows users to send e-mail messages to an SMTP e-mail server. Use the debug event
manager tcl smtp_library CLI command to debug issues with the SMTP library. When enabled, this
command displays all data that is passed in and read back from the SMTP library routines. This data
helps ensure users that the commands they are passing to the SMTP library are valid.
• Tcl is a flexible language that allows you to override commands. For example, you can modify the set
command and create a version of the set command that displays a message when a scalar variable is set.
