Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document shows how to combine the Expression MIB and the Event MIB for use in fault management. The included example is not realistic but shows many available features.

The router must perform two actions:

Send a trap if a loopback interface has a bandwidth higher than 100 and is administratively down
The loopback interface shuts down if one of the interfaces has its bandwidth statement changed from a defined value

The example is shown with bandwidth and admin status because they are easy to manipulate from the command line and both show integer and boolean values.

The commands in this document use the object identifier (OID) parameter and not the object names. This allows testing without loading the MIB.

Prerequisites

Requirements

Before using the information in this document, ensure that you meet the following prerequisites:

The workstation should have Simple Network Management Protocol (SNMP) tools provided by Hewlett-Packard (HP) Openview. Other SNMP tools work but may have different syntax.
The device must run Cisco IOS® Software Release 12.2(4)T3 or later. Earlier versions do not support the RFC version of the Event MIB.
The platform must support the Event MIB. For a list of supported platforms for Cisco IOS Software Release 12.1(3)T, refer to the "Supported Platform" section of Event MIB Support.

Components Used

The information in this document is based on these software and hardware versions:

Cisco IOS Software Release 12.3(1a)
Cisco 3640 Modular Access Router

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Conventions

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Background Information

The Expression MIB allows the user to create his own MIB object based on a combination of other objects. For more information, refer to RFC 2982 .
The Event MIB allows the user to have the device monitoring its own MIB objects and to generate actions (notification or SNMP SET commands) based on a defined event. For more information, refer to RFC 2981 .

Configure

Note: Some of the lines of output code are displayed over two lines to better fit onto your screen.

In this example, the ifIndex of the loopback interface is equal to 16.

# snmpget -v 2c -c private router .1.3.6.1.2.1.2.2.1.2.16
IF-MIB::ifDescr.16 = STRING: Loopback0

The variable names related to the first event start with e1 and those related to the second start with e2. The router name is "router" and the read/write community string is "private."

The Expression MIB

Creating the Expression 1

First create an expression that returns a value of 1 if the condition, ifSpeed is greater than 100,000 AND ifAdminStatus is down for the loopback interface. If the condition is not met, it returns the value 0.

expExpressionDeltaInterval—This object is not used.

There is no reason to calculate an expression when it is not polled. If no value is set, the expression is calculated when the object is queried.

The expression name is e1exp, which in the ASCII table corresponds to 101 49 101 120 112.

expNameStatus—This destroys an eventual old expression that is created.

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.2.3.1.3.101.49.101.120.112 integer 6

expNameStatus—Create and wait.

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.2.3.1.3.101.49.101.120.112 integer 5

expExpressionIndex—This creates the index to use later to retrieve the result of the expression.
```
# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.2.3.1.2.101.49.101.120.112 gauge 1
```
expExpressionComment—Here .1 (the chosen expExpressionIndex) is the description of the expression.
```
# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.1.1.4.1 octetstring "e1 expression"
```

expExpression—This is the expression itself, the variables $1 and $2 are defined at the next step.

The only allowed operators are (for details, refer to RFC 2982 ):

( )
- (unary)
+ - * / %
& | ^ << >> ~
! && || == != > >= < <=

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.1.1.2.1 octetstring '$1 < 100000 && $2 == 2'

expObjectID

.1 is for the variable $1 => ifSpeed
.2 for $2 => ifAdminStatus

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.2.1.1 objectidentifier 1.3.6.1.2.1.2.2.1.5.16

expObjectSampleType—The two values are taken in absolute values (for Delta, take 2 as the value).

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.4.1.1 integer 1
# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.4.1.2 integer 1

expObjectIDWildcard—The object IDs are not wildcarded. This is the default value, so do not snmpset expObjectIDWildcard.

expObjectStatus—Set the rows in the expObjectTable to active.

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.10.1.1 integer 1
# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.10.1.2 integer 1

Activate the expression 1.

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.2.3.1.3.101.49.101.120.112 integer 1

Testing the Expression 1

router(config)#interface loopback 0
router(config-if)#shutdown
router(config-if)#bandwidth 150

If the condition is met, the value of expValueCounter32Val is 1 (as the value of expExpressionValueType remains unchanged, the result is a counter32).

Note: The type cannot be a floating point value.
```
# snmpwalk -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.4.1.1.2
cisco.ciscoExperiment.22.1.4.1.1.2.1.0.0.0 : Counter: 1


router(config-if)#bandwidth 150000
```

If the condition is not met, the value is 0.

# snmpwalk -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.4.1.1.2
cisco.ciscoExperiment.22.1.4.1.1.2.1.0.0.0 : Counter: 0

router(config-if)#bandwidth 1     
router(config-if)#no shutdown

If the condition is not met, the value is 0.

# snmpwalk -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.4.1.1.2
cisco.ciscoExperiment.22.1.4.1.1.2.1.0.0.0 : Counter: 0

expObjectIDWildcard—This indicates that 1.3.6.1.2.1.2.2.1.5 is a table and not an object.

# snmpset -v 2c -c private router 1.3.6.1.4.1.9.10.22.1.3.2.1.3.2.1 integer 1

Event MIB

Creating Event 1

Now create an event that checks the output value of the first expression every 60 seconds and compares it with a reference. When the reference matches the expression value, a trap is triggered with the chosen VARBIND.

Create the trigger in the trigger table.
- The name of the trigger is trigger1, which in ASCII code is 116 114 105 103 103 101 114 49.
- The owner is tom: 116 111 109.
- The index of the mteTriggerEntry is composed of the trigger owner and the trigger name. The first value of the index gives the number of characters for the mteOwner.
  
  In this case, there are three characters for tom, so the index is: 3.116.111.109.116.114.105.103.103.101.114.49.
Destroy the old entry if it exists.
Set the trigger status to create and wait.

The last step activates it:

mteTriggerEntryStatus

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.15.3.116.111.109.116.114.105.103.103.101.114.49 
integer 6
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.15.3.116.111.109.116.114.105.103.103.101.114.49 
integer 5

mteTriggerValueID—The value of the first expression is e1exp.

The object identifier of the MIB object is the one to sample to see if the trigger should fire.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.6.3.116.111.109.116.114.105.103.103.101.114.49 
objectidentifier
1.3.6.1.4.1.9.10.22.1.4.1.1.2.1.0.0.0

mteTriggerValueIDWildcard—Without using a wildcard for the value ID.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.7.3.116.111.109.116.114.105.103.103.101.114.49 
integer 2

mteTriggerTest—Existence (0), boolean (1), and threshold (2).

The method to select one of the above values is a complex. To select an existence, give a value in eight digits in which the first is a 1, such as 10000000 or 100xxxxx.

For a boolean, the second digit must be a 1: 01000000 or 010xxxxx.

For a threshold, the third digit must be a 1: 00100000 or 001xxxxx.

It is easiest to work this way:
- For existence, the value is octetstringhex—80.
- For boolean, the value is octetstringhex—40.
- For threshold, the value is octetstringhex—20.
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.4.3.116.111.109.116.114.105.103.103.101.114.49 
octetstringhex "40"
```
mteTriggerFrequency—This determines the number of seconds to wait between trigger samples.

The minimum value is set with the object mteResourceSampleMinimum (default is 60 seconds), lowering this value increases the CPU usage, so it must be done carefully.
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.11.3.116.111.109.116.114.105.103.103.101.114.49 
gauge 60
```

mteTriggerSampleType—These are absoluteValue (1) and deltaValue (2). In this case, the value is absolute:

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.5.3.116.111.109.116.114.105.103.103.101.114.49 
integer 1

mteTriggerEnabled—This is a control that allows a trigger to be configured but not used. Set it to true (default is false).
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.2.1.14.3.116.111.109.116.114.105.103.103.101.114.49 
integer 1
```

Now that the trigger as been created, define the event the trigger will use. The event name is event1.

mteEventEntryStatus

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.5.3.116.111.109.101.118.101.110.116.49 
integer 6
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.5.3.116.111.109.101.118.101.110.116.49 
integer 5

mteEventActions—These are notification (0) and set (1).

The process is the same as for mteTriggerTest. Notification is 10xxxxxx and set is 01xxxxxx.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.3.3.116.111.109.101.118.101.110.116.49 
octetstringhex "80"
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.4.3.116.111.109.101.118.101.110.116.49 
integer 1

This next step defines the test to be done on the object selected for trigger1.

mteTriggerBooleanComparison—These are unequal (1), equal (2), less (3), lessOrEqual (4), greater (5), and greaterOrEqual (6). In this case—equal.
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.5.1.1.3.116.111.109.116.114.105.103.103.101.114.49 
integer 2
```
mteTriggerBooleanValue—This is the value to use for the test. If the value of 1.3.6.1.4.1.9.10.22.1.4.1.1.2.1.0.0.0 is equal to 1, then the condition is met.
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.5.1.2.3.116.111.109.116.114.105.103.103.101.114.49 
integer 1
```

Now define the object to be sent with the event.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.5.3.116.111.109.101.118.101.110.116.50 
integer 5

mteEventActions—The value 40 is for Set, meaning that when the condition is met, the router issues an snmp set command. In this case, it makes the Set for itself, but it could also make the operation on a remote device.
```
# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.3.3.116.111.109.101.118.101.110.116.50 
octetstringhex "40"
```

Enable the event.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.4.2.1.4.3.116.111.109.101.118.101.110.116.50 
integer 1

Set The Trigger Threshold in the Trigger Table // index = mteTriggerName—Trigger2.

As it is a threshold, give values for failing and rising conditions. Take only the rising condition this time.

mteTriggerThresholdDeltaRising—This is the threshold value to check against.

# snmpset -v 2c -c private router 1.3.6.1.2.1.88.1.2.6.1.4.3.116.111.109.116.114.105.103.103.101.114.50
