sample (event trigger)

To specify the type of object sampling to use for an event, use the samplecommand in event trigger configuration mode. To disable teh configured settings, use the no form of this command.

sample { absolute | delta | changed }

no sample { absolute | delta | changed }

Syntax Description

absolute	Uses the present value of the MIB object while sampling.
delta	Uses the difference between the present value and the previous value sampled at the previous interval for sampling.
changed	Uses the Boolean condition to check if the present value is different from the previous value.

Command Default

The default sampling method is absolute.

Command Modes

Event trigger configuration (config-event-trigger)

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 sample command enables the specified sampling method for the object. You can specify the following sampling methods.

• Absolute
• Delta
• Changed

Absolute sampling uses the value of the MIB object during sampling. The default sampling method is absolute.

Delta sampling uses the last sampling value maintained in the application. This method requires applications to do continuous sampling.

The changed sampling method uses the changed value of the object since the last sample.

Examples

The following example shows how to specify the sampling method as absolute:

Router(config)# snmp mib event trigger owner owner1 name triggerA
Router(config-event-trigger)# sample absolute

Related Commands

Command	Description
snmp mib event trigger owner	Specifies owner for an event trigger.

sample (expression)

To specify the method of sampling an object, use the sample command in expression object configuration mode. To disable the specified method of object sampling, use the no form of this command.

sample { absolute | delta | changed }

no sample

Syntax Description

absolute	Uses the present value of the MIB object while sampling.
delta	Uses the difference between the present value and the previous value sampled at the previous interval for sampling.
changed	Uses a Boolean condition to check if the present value is different from the previous value.

Command Default

The default sampling method is absolute.

Command Modes

Expression object configuration (config-expression-object)

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.
12.2(50)SY	This command was integrated into Cisco IOS Release 12.2(50)SY.

Usage Guidelines

The Expression MIB allows you to create expressions based on a combination of objects. The expressions are evaluated according to the sampling method. The Expression MIB supports the following types of object sampling:

• Absolute
• Delta
• Changed

The sample command enables the specified sampling method for the object. If there are no delta or changed values in an expression, the expression is evaluated when a requester attempts to read the value of the expression. In this case, all requesters get a newly calculated value.

For expressions with delta or change values, the evaluation is performed for every sampling. In this case, requesters get the value as the last sample period.

Examples

The following example shows how to specify the sampling method as absolute:

Router(config)# snmp mib expression owner owner1 name expressionA
Router(config-expression)# object 32
Router(config-expression-object)# sample absolute
Router(config-expression-object)# end

Related Commands

Command	Description
snmp mib expression owner	Specifies the owner for an expression.

schema

To specify the bulk statistics schema to be used in a specific bulk statistics transfer configuration, use the schema command in Bulk Statistics Transfer configuration mode. To remove a previously configured schema from a specific bulk statistics transfer configuration, use the no form of this command.

schema schema-name

no schema schema-name

Syntax Description

schema-name

Name of a previously configured bulk statistics schema.

Command Default

No bulk statistics schema is specified.

Usage Guidelines

SNMP management information is viewed as a collection of managed objects, residing in a virtual information store, termed the Management Information Base (MIB). Collections of related objects are defined in MIB modules. These modules are written using a subset of OSIs Abstract Syntax Notation One (ASN.1), termed the Structure of Management Information (SMI).

This command is intended for network administrators who are familiar with the SMI and ASN.1 syntax.

While this command can be used to display a list of MIB object identifiers (OIDs) registered on the system, the use of a network management system (NMS) application is the recommended alternative for gathering this information.

The show snmp mib command will display the instance identifiers for all the MIB objects on the system. The instance identifier is the final part of the OID. An object can have one or more instance identifiers. Before displaying the instance identifier, the system attempts to find the best match with the list of table names. The MIB module table names are registered when the system initializes.

The definitions for the OIDs displayed by this command can be found in the relevant RFCs and MIB modules. For example, RFC 1907 defines the system.x, sysOREntry.x, snmp.x, and snmpTrap.x OIDs, and this information is supplemented by the extensions defined in the CISCO-SYSTEM-MIB.

Tip	This command produces a high volume of output if SNMP is enabled on your system. To exit from a --More-- prompt, press Ctrl-Z.

Command History

Release	Modification
12.4(15)T	This command was introduced.
12.2(33)SXH	This command was integrated into Cisco IOS Release 12.2(33)SXH.

Usage Guidelines

Simple Network Management Protocol (SNMP) contexts provide VPN users with a secure way of accessing MIB data. When a VPN is mapped to a context, the data specific to that VPN exists in that context. Associating a VPN with a context enables service providers to manage networks with multiple VPNs. Creating and associating a context with a VPN enables a provider to prevent the users of one VPN from accessing information about users of other VPNs on the same networking device.

To configure SNMP contexts, use the snmp-server contextcommand.

Examples

The following is sample output from the show snmp mib contextcommand. The example lists the MIBs that are VPN-aware. The output is self-explanatory.

default	(Optional) Displays summary information for the default (unnamed) SNMP Notification Log.

Command Modes

EXEC

Command History

Release	Modification
12.0(22)S	This command was introduced.
12.2(13)T	This command was integrated into Release 12.2(13)T.

Usage Guidelines

The SNMP Notification Log works in conjunction with the NOTIFICATION-LOG-MIB.my MIB module (available at ftp://ftp.cisco.com/pub/mibs/v2/). This MIB module is based on RFC 3014. The local logs can be polled by external network management applications to verify that they have not missed important SNMP notifications (traps and informs).

The show snmp mib notification-log allcommand displays all logged notification entries currently in the local MIB database. Entries are displayed from the oldest to the newest. The time of entry creation is determined using the system-up-time (sysUpTime) value; this means that the age of the entry is set using the amount of time that has passed since the router was last restarted. Other information for the entries includes the notificationID, and the filters (varbinds) associated with the log, if any.

Examples

The following is sample output from the show snmp mib notification-log command:

Router# show snmp mib notification-log
 
GlobalAgeout 15, GlobalEntryLimit 500
Total Notifications logged in all logs 0
Log Name””, Log entry Limit 500, Notifications logged 0
Logging status enabled
Created by cli

Note that in this example, the Log Name of ““ indicates the default “null-named” Notification Log.

Related Commands

Command History

Release	Modification
12.4(10)	This command was introduced.
12.2(44)SE	This command was integrated into Cisco IOS Release 12.2(44)SE and the type keyword was added.

Usage Guidelines

Use the show snmp sysobjectid command to quickly identify a device. The same information can be obtained by issuing an SNMP query on the MIB object sysObjectID. Output from the command shows the system object ID in dotted decimal format. The system object ID is the identifier of the network management subsystem, which is SNMP, and is typically the starting point at which network management applications try to discover a device.

Use the show snmp sysobjectid type command to identify the system object ID type.

Examples

The following is sample output from the show snmp sysobjectid command. In this example, the object ID translates to iso.org.dod.internet.private.enterprises.cisco.ciscoProducts.ciscoGatewayServer.

Router# show snmp sysobjectid

Usage Guidelines

An SNMP user must be part of an SNMP group, as configured using the snmp-server user username group-name command.

When the usernameargument is not entered, the show snmp usercommand displays information about all configured users. If you specify the usernameargument, if one or more users of that name exists, the information pertaining to those users is displayed. Because this command displays users configured with the SNMP engine ID of the local agent and other engine IDs, there can be multiple users with the same username.

When configuring SNMP, you may see the logging message “Configuring snmpv3 USM user.” USM stands for the User-based Security Model for version 3 of the Simple Network Management Protocol (SNMPv3). For further information on the USM, see RFC 2574.

Examples

The following is sample output from the show snmp user command. The output indicates the username as authuser, the engine ID string as 00000009020000000C025808, and the storage type as nonvolatile:

Router# show snmp user

snmp context (VRF)

To associate a Simple Network Management Protocol (SNMP) context with a particular VPN routing and forwarding (VRF) instance, use the snmp context command in VRF configuration mode. To disassociate an SNMP context from a VPN, use the no form of this command.

snmp context context-name

no snmp context

Syntax Description

context-name

Name of the SNMP VPN context. The name can be up to 32 alphanumeric characters.

Command Default

No SNMP contexts are associated with VPNs.

Command Modes

VRF configuration (config-vrf)

Command History

Release	Modification
15.0(1)M	This command was introduced. This command replaces the context command.

Usage Guidelines

Before you use the snmp contextcommand to associate an SNMP context with a VPN, you must do the following:

• Issue the snmp-server context command to create an SNMP context.
• Associate a VPN with a context so that the specific MIB data for that VPN exists in the context.
• Associate a VPN group with the context of the VPN using the context context-namekeyword argument pair of the snmp-server group command.

SNMP contexts provide VPN users with a secure way of accessing MIB data. When a VPN is associated with a context, MIB data for that VPN exists in that context. Associating a VPN with a context helps service providers to manage networks with multiple VPNs. Creating and associating a context with a VPN enables a provider to prevent the users of one VPN from accessing information about other VPN users on the same networking device.

A route distinguisher (RD) is required to configure an SNMP context. An RD creates routing and forwarding tables and specifies the default route distinguisher for a VPN. The RD is added to the beginning of an IPv4 prefix to make it globally unique. An RD is either an autonomous system number (ASN) relative, which means that it is composed of an autonomous system number and an arbitrary number, or an IP address relative and is composed of an IP address and an arbitrary number.

Examples

The following example shows how to create an SNMP context named context1 and associate the context with the VRF named vrf1:

Router(config)# snmp-server context context1
Router(config)# ip vrf vrf1
Router(config-vrf)# rd 100:120
Router(config-vrf)# snmp context context1

Command History

Release	Modification
12.2(33)SRC	This command was introduced.
12.2(33)SXI	This command was integrated into Cisco IOS Release 12.2(33)SXI.

Usage Guidelines

The get requests are sent by the SNMP manager or the Network Management System (NMS) to retrieve SNMP object variables. The snmp get command is used to retrieve the exact object variable.

The community string for a get operation can be set to either of the following types:

• ro--Sets the read-only access to the SNMP entity. The default value for this community string is public.
• rw--Sets read-write access to the SNMP entity. The default value for this community string is private.

Examples

Command History

Release	Modification
12.2(33)SRC	This command was introduced.
12.2(33)SXI	This command was integrated into Cisco IOS Release 12.2(33)SXI.

Usage Guidelines

For getBulk operation, if you specify 1 as the value for the non-repeaterskeyword, the first OID value specified in the command syntax is not repeated at the getNext operation. In other words, a simple getNext operation is performed to retrieve this variable. The max-repetition keyword specifies the number of getNext attempts to make while the remaining object variables are retrieved. If the max-repetitions keyword value is specified as 2, there will be two getNext attempts to retrieve the remaining variables.

For example, if the non-repeaters keyword is specified as 1 and variables to retrieve are specified as sysName.0, ifDescr, and ifName, a simple getNext operation is performed to retrieve the sysName.0 variable. The value specified for the max-repetitions keyword is used to determine the number of getNext attempts to make while the remaining object variables are retrieved.

The community string for a get-bulk operation can be set to either of the following types:

• ro--Sets the read-only access to the SNMP entity. The default value for this community string is public.
• rw--Sets read-write access to the SNMP entity. The default value for this community string is private.

Examples

The following example shows how to send a getBulk operation request by using SNMPv2C:

12.2(28)SB	This command was integrated into Cisco IOS Release 12.2(28)SB.

Usage Guidelines

The ifAlias object (ifXEntry 18) of the Interfaces MIB (IF-MIB) is called the Interface Alias. The Interface Alias (ifAlias) is a user-specified description of an interface used for Simple Network Management Protocol (SNMP) network management. The ifAlias is an object in the Interfaces Group MIB (IF-MIB) which can be set by a network manager to “name” an interface.

The ifAlias value for an interface or subinterface can be set using the description command in interface configuration mode or subinterface configuration mode, or by using a Set operation from an NMS. Prior to the introduction of this command, ifAlias descriptions for subinterfaces were limited to 64 characters. (The OLD-CISCO-INTERFACES-MIB allows up to 255 characters for the locIfDescr MIB variable, but this MIB does not support subinterfaces.) IfAlias descriptions appear in the output of the show interfaces command in EXEC mode, and in the output of the more system: running-config or show running-config commands in EXEC mode.

Examples

In the following example, the system is configured to retain and return ifAlias values of up to 256 characters in length:

Router(config)# snmp ifmib ifalias long

Usage Guidelines

SNMP inform requests are the SNMP notifications that alert the SNMP manager to a network condition and request confirmation of receipt from the SNMP manager.

The community string for sending inform requests can be set to either of the following types:

• ro--Sets the read-only access to the SNMP entity. The default value for this community string is public.
• rw--Sets read-write access to the SNMP entity. The default value for this community string is private.

Examples

The following example shows how to send an inform request using SNMPv2c:

Router# snmp inform v2c 10.16.2.8 public retry 2 timeout 60 trap-oid system.2.0 oid sysUpTime.0 counter 20

Usage Guidelines

The snmp mib bulkstat object-list command allows you to name an object list. Bulk statistics object lists are used for the Periodic MIB Data Collection and Transfer Mechanism.

After you enter this command, the router enters Bulk Statistics Object List configuration mode, in which you can use the add command to add specific MIB objects to the list.

Bulk statistics object lists can be reused in multiple schemas.

Examples

In the following example, a bulk statistics object list called ifMib is configured to include the ifInoctets, ifOutoctets, ifInUcastPkts, and ifInDiscards objects from the Interfaces Group MIB (IF-MIB):

Router(config)# snmp mib bulkstat object-list ifmib
 
Router(config-bulk-objects)# add ifInoctets
 
Router(config-bulk-objects)# add ifOutoctets
 
Router(config-bulk-objects)# add ifInUcastPkts

Usage Guidelines

The snmp mib bulkstat schema command names the schema and enters Bulk Statistics Schema configuration mode. Bulk Statistics Schema configuration mode is used to configure the object list, instance, and polling interval to be used in the schema.

The specific instances of MIB objects for which data should be collected are determined by appending the value of the instance command to the objects specified in the object list.

Multiple schemas can be associated with a single bulk statistics file when configuring the bulk statistics transfer options.

Examples

The following example shows the configuration of a bulk statistics schema called ATM2/0-IFMIB:

Router(config)# snmp mib bulkstat schema ATM2/0-IFMIB
 
Router(config-bulk-sc)# object-list ifmib
 
Router(config-bulk-sc)# poll-interval 5
 
Router(config-bulk-sc)# instance exact interface ATM2/0 subif
 
Router(config-bulk-sc)# exit

When an SNMP community is associated with an SNMP context and a request is made from this community, the request is applied to the context. You also can use the snmp mib community-map command to specify the source address validation for an SNMP community by associating a list of target VRFs. The target VRF list specifies the valid host or hosts for this SNMP community.

Examples

The following example shows how to create an SNMP community named community1 and associate it with an SNMP context named context1:

Router(config)# snmp-server community community1
Router(config)# snmp mib community-map community1 context context1

The following example shows a mapping of community A (commA) to VPN list commAvpn and community B (commB) to VPN list commBvpn:

Router(config)# snmp mib community-map commA context A target-list commAvpn
Router(config)# snmp mib community-map commB context B target-list commBvpn
Router(config)# snmp mib target list commAvpn vrf CustomerA
