S through Z Commands

set (EEM)

Note

Effective with Cisco IOS Release 12.4(22)T, the set (EEM) command is replaced by the action set (EEM) command. See the action set (EEM) command for more information.

To set the value of a local Embedded Event Manager (EEM) applet variable, use the set command in applet configuration mode. To remove the value of an EEM applet variable, use the no form of this command.

set label variable-name variable-value

no set label variable-name variable-value

Syntax Description


`label`	Unique identifier that can be any string value. Actions are sorted and run in ascending alphanumeric key sequence using the label as the sort key. If the string contains embedded blanks, enclose it in double quotation marks.
`variable-name`	The EEM applet variable name. Currently only the _exit_status variable is supported.
`variable-value`	Integer value that represents the variable. For the _exit_status variable, this is the value that represents the exit status for the applet. Zero represents a successful exit status, and a nonzero value represents a failed exit status.

Command Default

No EEM applet variable values are set.

Command Modes

Applet configuration (config-applet)

12.2(28)SB	This command was integrated into Cisco IOS Release 12.2(28)SB.
12.2(18)SXF4	This command was integrated into Cisco IOS Release 12.2(18)SXF4 to support Software Modularity images only.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2(18)SXF5	This command was integrated into Cisco IOS Release 12.2(18)SXF5.
12.2SX	This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
12.4(22)T	This command was replaced by the action set command.

Usage Guidelines

In EEM applet configuration mode, three types of configuration statements are supported. The event commands are used to specify the event criteria to trigger the applet to run, the action commands are used to specify an action to perform when the EEM applet is triggered, and the set command is used to set the value of an EEM applet variable. Currently only the _exit_status variable is supported for the set command.

Examples

The following example shows how to set the _exit_status variable to represent a successful status after an event has occurred three times and an action has been performed:


Router(config)# event manager applet cli-match
Router(config-applet)# event cli pattern {.*interface loopback*} sync yes occurs 3
Router(config-applet)# action 1.0 cli command "no shutdown"
Router(config-applet)# set 1.0 _exit_status 0

Usage Guidelines

Use this command to display the username associated with a Tool Command Language (Tcl) EEM policy. If you are using authentication, authorization, and accounting (AAA) security and implement authorization on a command basis, you should use the event manager session cli username command to set a username to be associated with a Tcl session. The username is used when a Tcl policy executes a CLI command. TACACS+ verifies each CLI command using the username associated with the Tcl session that is running the policy. Commands from Tcl policies are not usually verified because the router must be in privileged EXEC mode to register the policy.

Examples

The following example shows that the username of eemuser is associated with a Tcl session:


Router# show event manager session cli username

track stub-object

To create a stub object that can be tracked by Embedded Event Manager (EEM) and to enter tracking configuration mode, use the track stub-object command in global configuration mode. To remove the stub object, use the no form of this command.

track object-number stub-object

no track object-number stub-object

Syntax Description


`object-number`	Object number that represents the object to be tracked. The range is from 1 to 1000.

Command Default

No stub objects are created.

Command Modes

Global configuration (config)

Command History


Release	Modification
12.4(2)T	This command was introduced.
12.2(31)SB3	This command was integrated into Cisco IOS Release 12.2(31)SB3.
12.2(33)SRB	This command was integrated into Cisco IOS Release 12.2(33)SRB.
Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS XE Release 2.1.

15.1(1)S	This command was modified. The valid range for the `object-number` argument increased to 1000.

Usage Guidelines

Use the track stub-object command to create a stub object, which is an object that can be tracked and manipulated by an external process, EEM. After the stub object is created, the default-state command can be used to set the default state of the stub object.

EEM is a distributed, scalable, and customized approach to event detection and recovery offered directly in a Cisco IOS device. EEM offers the ability to monitor events and take informational or corrective action when the monitored events occur or when a threshold is reached. An EEM policy is an entity that defines an event and the actions to be taken when that event occurs.

As of Cisco IOS Release 15.1(3)T, a maximum of 1000 objects can be tracked. Although 1000 tracked objects can be configured, each tracked object uses CPU resources. The amount of available CPU resources on a router is dependent upon variables such as traffic load and how other protocols are configured and run. The ability to use 1000 tracked objects is dependent upon the available CPU. Testing should be conducted on site to ensure that the service works under the specific site traffic conditions.

Examples

The following example shows how to create and configure stub object 1 with a default state of up:


Router(config)# 
track 1 stub-object
Router(config-track)#
 default-state up

Related Commands


Command	Description
default-state	Sets the default state for a stub object.
show track	Displays tracking information.

trigger (EEM)

To enter trigger applet configuration mode and specify the multiple event configuration statements for an Embedded Event Manager (EEM) applet, use the trigger command in applet configuration mode. To disable the multiple event configuration statements, use the no form of this command.

trigger [occurs occurs-value] [period period-value] [period-start period-start-value] [delay delay-value]

no trigger [occurs occurs-value] [period period-value] [period-start period-start-value] [delay delay-value]

Syntax Description


occurs	(Optional) Specifies the number of times the total correlation occurs before an EEM event is raised. When a number is not specified, an EEM event is raised on the first occurrence.
`occurs-value`	(Optional) Number in the range from 1 to 4294967295.
period	(Optional) Specifies the time interval during which the one or more occurrences must take place. If not specified, the time-period check is not applied.
`period-value`	(Optional) Number that represents seconds and optional milliseconds in the format ssssssssss[.mmm]. The range for seconds is from 0 to 4294967295. The range for milliseconds is from 0 to 999. If using milliseconds only, specify the milliseconds in the format 0.mmm.
period-start	(Optional) Specifies the start of an event correlation window. If not specified, event monitoring is enabled after the first CRON period occurs.
`period-start-value`	(Optional) String that specifies the beginning of an event correlation window.
delay	(Optional) Specifies the number of seconds after which an event will be raised if all the conditions are true. If not specified, the event will be raised immediately.
`delay-value`	(Optional) Number that represents seconds and optional milliseconds in the format ssssssssss[.mmm]. The range for seconds is from 0 to 4294967295. The range for milliseconds is from 0 to 999. If using milliseconds only, specify the milliseconds in the format 0.mmm.

Command Default

Disabled.

Command Modes

Applet configuration (config-applet)

Command History


Release	Modification
12.4(20)T	This command was introduced.
12.2(33)SRE	This command was integrated into Cisco IOS Release 12.2(33)SRE.

Usage Guidelines

The trigger command relates multiple event statements using the optional tag keyword with the event-tag argument specified in each event statement.

Examples

The following example shows how to use the trigger command to enter trigger applet configuration mode and specify multiple event configuration statements for an EEM applet. In this example, the applet is run when the show bgp all command and any syslog message that contains the string “COUNT” occurs within a period of 60 seconds.


Router(config)# event manager applet delay_50
Router(config-applet)# event
 tag 1.0 cli pattern "show bgp all" sync yes occurs 32 period 60 maxrun 60
Router(config-applet)# event
 tag 2.0 syslog pattern "COUNT"
Router(config-applet)# trigger occurs 1 delay 50
Router(config-applet-trigger)# correlate event 1.0 or event 2.0
Router(config-applet-trigger)# attribute tag 1.0 occurs 1
Router(config-applet-trigger)# attribute tag 2.0 occurs 1
Router(config-applet-trigger)# action 1.0 cli command "show memory"
Router(config-applet)# action 2.0 cli command "enable"
Router(config-applet)# action 3.0 cli command "config terminal"
Router(config-applet)# action 4.0 cli command " ip route 192.0.2.0 255.255.255.224 192.0.2.12"
Router(config-applet)# action 91.0 cli command "exit"
Router(config-applet)# action 99.0 cli command "show ip route | incl 192.0.2.5"
