Configuration Examples to Create a Supplemental Policy

This section includes the following topics:

Creating a Supplemental Policy for the Fan Absent Event

Creating a Supplemental Policy for the Temperature Threshold Event

Creating a Supplemental Policy for the Fan Absent Event

This example shows how to create a supplemental policy using the event fanabsent command:

[no] event fanabsent [fan fan-number] time time-interval

In addition to the default policy, this example shows how to execute the policy myappletname and action 3 if fan 1 is absent for 60 seconds:

switch# config t
switch(config)# event manager applet myappletname
switch(config-applet)# event fanabsent fan 1 time 60
switch(config-applet)# action 3 cli "show env fan"
switch(config-applet)# end

Creating a Supplemental Policy for the Temperature Threshold Event

[no] event temperature [mod module-number] [sensor sensor-number] threshold {major | minor | any}

In addition to the default policy, this example shows how to execute the policy myappletname and action 1 if the temperature crosses the minor threshold on sensor 3 of module 2:

switch# config t
switch(config)# event manager applet myappletname
switch(config-applet)# event temperature module 2 sensor 3 threshold minor
switch(config-applet)# action 1 cli "show environ temperature"
switch(config-applet)# end

Configuration Examples for the Power Over-Budget Policy

The power over-budget policy gets triggered when the available power capacity drops below zero and the device is no longer able to keep the previously powered-up modules in the powered-up state. The default action is to print a syslog to notify the user of the occurrence of power over budget.

You can enable an additional action to power down modules until the available power recovers from the red (negative) zone.

This section includes the following topics:

Shutting Down Modules

Shutting Down a Specified List of Modules

Shutting Down Modules

If you do not specify any modules, the power over-budget shutdown starts from slot 1 and shuts down modules until the power recovers from the red (negative) zone. Empty slots and slots that contain a supervisor, standby supervisor, spine, or crossbar are skipped.

This example shows how to shut down modules starting from module 1 when the available power drops below zero:

switch# config t
switch(config)# event manager applet <myappletname4a> override __pfm_power_over_budget
switch(config-applet)# event poweroverbudget
switch(config-applet)# action 4 overbudgetshut
switch(config-applet)# end

Shutting Down a Specified List of Modules

You can specify a list of modules that the power over-budget action uses to shut down modules until the power recovers from the red (negative) zone. Empty slots and slots that contain a supervisor, standby supervisor, spine, or crossbar are skipped.

This example shows how to shut down modules from a specified list of modules (1, 2, 7, 8) when the available power drops below zero:

switch# config t
switch(config)# event manager applet <myappletname4b> override __pfm_power_over_budget
switch(config-applet)# event poweroverbudget
switch(config-applet)# action 5 overbudgetshut module 1,2,7,8
switch(config-applet)# end

Configuration Examples to Select Modules to Shut Down

This section includes the following topics.:

Using the Policy Default to Select Nonoverridden Modules to Shut Down

Using Parameter Substitution to Select Nonoverridden Modules to Shut Down

Using the Policy Default to Select Nonoverridden Modules to Shut Down

This example shows how to use the policy default to select the nonoverridden modules to shut down when a major threshold is exceeded:

switch# config t
switch(config)# event manager applet my5a1 override __pfm_tempev_major
switch(config-applet)# end
switch# config t
switch(config)# event manager applet my5a2 override __pfm_tempev_major
switch(config-applet)# event temperature module 1-3 sensor 4 threshold major
switch(config-applet)# action 5 policy-default
switch(config-applet)# end

Using Parameter Substitution to Select Nonoverridden Modules to Shut Down

This example shows how to use parameter substitution to select the nonoverridden modules to shut down when a major threshold is exceeded:

switch# config t
switch(config)# event manager applet my5b1 override __pfm_tempev_major
switch(config-applet)# end
switch# config t
switch(config)# event manager applet my5b2 override __pfm_tempev_major
switch(config-applet)# event temperature module 1-3 sensor 8 threshold major
switch(config-applet)# action 6 forceshut module my_module_list reset "temperature-sensor 
policy trigger"
switch(config-applet)# end

To create event manager parameters, use the event manager environment command. To display the values of event manager parameters, use the show event manager environment all command.

Configuration Examples for the Online Insertion Removal Event

The online insertion removal (OIR) event does not have a default policy.

This example shows how to configure the OIR event using the event oir command:

event oir device-type event-type [device-number]

The device-type can be fan, module or powersupply.

The event-type can be insert, remove, or anyoir (insert or remove).

The optional device-number specifies a single device. If omitted, all devices are selected.

This example shows how to configure the insert event:

switch# config t
switch(config)# event manager applet myoir
switch(config-applet)# event oir module insert
switch(config-applet)# action 1 syslog priority critical msg "OIR insert event: A Module 
is inserted"

This example shows how to configure the remove event:

switch# config t
switch(config)# event manager applet myoir
switch(config-applet)# event oir module remove
switch(config-applet)# action 1 syslog priority critical msg "OIR remove event: A Module 
is removed"

Configuration Example to Generate a User syslog

This example shows how to generate a user syslog using the action syslog command.

switch# config t
switch(config)# event manager applet myoir
switch(config-applet)# event oir module remove
switch(config-applet)# action 1 syslog priority critical msg "Module is removed"

When this event is triggered, the system will generate a syslog as follows:

p1b-57(config)# 2008 Feb 20 00:08:27 p1b-57 %$ VDC-1 %$ %EEM_ACTION-2-CRIT: "Module is removed"

2008 Feb 20 00:08:27 p1b-57 %$ VDC-1 %$ %PLATFORM-2-MOD_REMOVE: Module 2 removed (Serial number JAB120101PW)

Configuration Examples for SNMP Notification

This section includes the following topics:

Polling an SNMP OID to Generate an EEM Event

Sending an SNMP Notification in Response to an Event in the Event Policy

Polling an SNMP OID to Generate an EEM Event

The SNMP object ID (OID) CISCO-SYSTEM-EXT-MIB::cseSysCPUUtilization is used for querying the CPU utilization of the switch:

cseSysCPUUtilization OBJECT-TYPE
    SYNTAX          Gauge32 (0..100 )
    UNITS           "%"
    MAX-ACCESS      read-only
    STATUS          current
    DESCRIPTION
        "The average utilization of CPU on the active supervisor."
    ::= { ciscoSysInfoGroup 1 }

This example shows the use of an SNMP OID that is polled at an interval of 10 seconds and has a threshold value of 95 percent:

switch# config t
switch(config)# event manager applet test_policy
switch(config-applet)# event snmp oid 1.3.6.1.4.1.9.9.305.1.1.1.0 get-type exact entry-op 
gt entry-val 95 exit-op lt exit-val 90 poll-interval 10

Sending an SNMP Notification in Response to an Event in the Event Policy

You can use this type of configuration to cause a critical event trigger to generate an SNMP notification.

This example shows how to send an SNMP notification for an event from the Event Manager applet configuration mode:

switch(config-applet)# action 1.1 snmp-trap intdata1 100 intdata2 300 strdata "CPU Hogging 
at switch1"
switch(config-applet)# action 1.1 snmp-trap intdata1 100 intdata2 300 strdata "Port 
Failure eth9/1"

This configuration triggers an SNMP notification (trap) from the switch to SNMP hosts. The SNMP payload carries the values of user-defined fields intdata1, intdata2, and strdata.

Configuration Example for Port Tracking

This example shows how to configure the state of one port to match the state of another port (port tracking).

To configure port tracking of Ethernet interface 3/23 by Ethernet interface 1/2, follow these steps:


Step 1 Create an object to track the status of Ethernet interface 3/23.

switch# config t
switch(config)# track 1 interface ethernet 3/23 
switch(config-track)# end 

Step 2 Configure an EEM event to shut Ethernet interface 1/2 when the tracking object shuts down.

switch(config)# event manager applet track_3_23_down
switch(config-applet)# event track 1 state down
switch(config-applet)# action 1 syslog msg EEM applet track_3_23_down shutting down port 
eth1/2 due to eth3/23 being down 
switch(config-applet)# action 2 cli conf term
switch(config-applet)# action 3 cli interface ethernet 1/2
switch(config-applet)# action 4 cli shut
switch(config-applet)# end 

Step 3 Configure an EEM event to bring up Ethernet interface 1/2 when Ethernet interface 3/23 comes up.

switch# config t
