action (event)

To set an action for an event, use the action command in event configuration mode. To disable the action for an event, use the no form of this command.

action {set | notification}

no action {set | notification}

Syntax Description

set	Specifies the action for an event.
notification	Enables notifications for events.

Command Default

No action is set for an event.

Command Modes

Event configuration (config-event)

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

While configuring a set of actions for an event, you can specify the object identifier of the object. You can also configure events to perform activities such as sending notifications or setting a MIB object whenever an event is triggered. If notifications are enabled for an event, the system sends a notification to the SNMP manager whenever the object configured for that event is modified.

Examples

The following example shows how to enable notifications for an event:

Router(config)# snmp mib event owner owner1 name test
Router(config-event)# action notification
Router(config-event-action-notification)# end

Command	Description
object id	Specifies the object identifier of an object.
snmp mib event owner	Specifies the event owner for a management event.
value	Specifies a value for the object configured for an event.
wildcard	Specifies whether an object used for evaluating an expression is to be wildcarded during an event configuration.

add (bulkstat object)

To add a MIB object to a bulk statistics object list, use the add command in Bulk Statistics Object List configuration mode. To remove a MIB object from an SNMP bulk statistics object list, use the no form of this command.

add {object-name | oid}

no add {object-name | oid}

Syntax Description

object-name	Name of the MIB object to add to the list. Only object names from the Interfaces MIB (IF-MIB.my), Cisco Committed Access Rate MIB (CISCO-CAR-MIB.my) and the MPLS Traffic Engineering MIB (MPLS-TE-MIB.my) may be used.
oid	Object ID (OID) of the MIB object to add to the list.Only OIDs from the Interfaces MIB (IF-MIB.my), Cisco Committed Access Rate MIB (CISCO-CAR-MIB.my) and the MPLS Traffic Engineering MIB (MPLS-TE-MIB.my) may be used.

Command Default

No MIB objects are listed in the bulk statistics object list.

Command Modes

Bulk Statistics Object List configuration (config-bulk-objects)

12.2(33)SB	This command was integrated into Cisco IOS Release 12.2(33)SB.
Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

All the objects in an object list have to be indexed by the same MIB index, but the objects need not belong to the same MIB table. For example, it is possible to group ifInoctets and an Ether MIB object in the same schema because the containing tables are indexed by the ifIndex (in the IF-MIB).

Object names are available in the relevant MIB modules. For example, the input byte count of an interface is defined in the Interfaces Group MIB (IF-MIB.my) as ifInoctets. Complete MIB modules can be downloaded from Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.

Examples

In the following example, two bulk statistics object lists are configured: one for IF-MIB objects and one for CISCO-CAR-MIB objects. Because the IF-MIB objects and the CISCO-CAR-MIB objects do not have the same index, they must be defined in separate object lists.

Router(config)# snmp mib bulkstat object-list if-Objects
 
Router(config-bulk-objects)# add ifInoctets 
Router(config-bulk-objects)# add ifOutoctets
 
Router(config-bulk-objects)# add ifInUcastPkts
 
Router(config-bulk-objects)# add ifInDiscards
 
Router(config-bulk-objects)# exit
 
Router(config)# snmp mib bulkstat object-list CAR-Objects 
Router(config-bulk-objects)# add CcarStatSwitchedPkts
 
Router(config-bulk-objects)# add ccarStatSwitchedBytes
 
Router(config-bulk-objects)# add CcarStatFilteredBytes
 
Router(config-bulk-objects)# exit
 
Router(config)#

bandwidth (interface)

To set the inherited and received bandwidth values for an interface, use the bandwidth command in interface or virtual network interface config mode. To restore the default values, use the no form of this command.

bandwidth [receive] {kbps | inherit [kbps]}

no bandwidth [receive] {kbps | inherit [kbps]}

Syntax Description

kbps	Intended bandwidth, in kilobits per second. The range is from 1 to 10000000. For a full bandwidth DS3 line, enter the value 44736.
inherit	(Optional) Specifies how a subinterface inherits the bandwidth of its main interface.
receive	(Optional) Enables asymmetric transmit/receive operations so that the transmitted (inherit kbps) and received bandwidth are different.

Command Default

Default bandwidth values are set during startup. The bandwidth values can be displayed using the show interfaces or show ipv6 interface command. If the receive keyword is not used, by default, the transmit and receive bandwidths will be assigned the same value.

Command Modes

Interface configuration (config-if)

Cisco IOS XE Release 3.2S	This command was modified. Support was added for this command in virtual network interface configuration mode.
15.1(03)S	This command was modified. Support was added for the receive keyword.

Usage Guidelines

Bandwidth Information

The bandwidth command sets an informational parameter to communicate only the current bandwidth to the higher-level protocols; you cannot adjust the actual bandwidth of an interface using this command.

Note

This is only a routing parameter. It does not affect the physical interface.

Changing Bandwidth

For some media, such as Ethernet, the bandwidth is fixed; for other media, such as serial lines, you can change the actual bandwidth by adjusting the hardware. For both classes of media, you can use the bandwidth command to communicate the current bandwidth to the higher-level protocols.

Bandwidth Inheritance

Before the introduction of the bandwidth inherit command option, when the bandwidth value was changed on the main interface, the existing subinterfaces did not inherit the bandwidth value. If the subinterface was created before the bandwidth was changed on the main interface, the subinterface would receive the default bandwidth of the main interface, and not the configured bandwidth. Additionally, if the router was subsequently reloaded, the bandwidth of the subinterface would then change to the bandwidth configured on the main interface.

The bandwidth inherit command controls how a subinterface inherits the bandwidth of its main interface. This functionality eliminates inconsistencies related to whether the router has been reloaded and what the order was in entering the commands.

The no bandwidth inherit command enables all subinterfaces to inherit the default bandwidth of the main interface, regardless of the configured bandwidth. If the bandwidth inherit command is used without configuring a bandwidth on a subinterface, all subinterfaces will inherit the current bandwidth of the main interface. If you configure a new bandwidth on the main interface, all subinterfaces will use this new value.

If you do not configure a bandwidth on the subinterface and you configure the bandwidth inherit kbps command on the main interface, the subinterfaces will inherit the specified bandwidth.

In all cases, if an explicit bandwidth setting is configured on an interface, the interface will use that setting, regardless of whether the bandwidth inheritance setting is in effect.

Bandwidth Receipt

Some interfaces (such as Asymmetric Digital Subscriber Line (ADSL), V.35, RS-449, and High-Speed Serial Interface (HSSI)) can operate with different transmit and receive bandwidths. The bandwidth receive command permits this type of asymmetric operation. For example, for ADSL, the lower layer detects the two bandwidth values and configures the Integrated Data Base (IDB) accordingly. Other interface drivers, particularly serial interface cards on low- and midrange-platforms, can operate in this asymmetric bandwidth mode but cannot measure their clock rates. In these cases, administrative configuration is necessary for asymmetric operations.

Examples

The following example shows how to set the full bandwidth for DS3 transmissions:

Router(config)# interface serial 0
Router(config-if)# bandwidth 44736

The following example shows how to set the receive bandwidth:

Router(config)# interface serial 0
Router(config-if)# bandwidth receive 1000

Related Commands

Command	Description
show interfaces	Displays statistics for all interfaces configured on the router.
show ipv6 interface	Displays statistics for all interfaces configured on the IPv6 router.

buffer-size (bulkstat)

12.2(33)SB	This command was integrated into Cisco IOS Release 12.2(33)SB.
15.0(1)M	This command was replaced by the snmp context command.

Usage Guidelines

Before you use the context command 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)# context context1

no correlate {event event-tag | track track-object-number} [andor | and | or] {event event-tag | track track-object-number}

Syntax Description

event event-tag	Specifies the event that can be used with the trigger command to support multiple event statements within an applet. If the event associated with the event-tag argument occurs for the number of times specified by the trigger command, the result is true. If not, the result is false.
track track-object-number	Specifies the event object number for tracking. The range is from 1 to 500. If the tracked object is set, the result of the evaluation is true. If the tracked object is not set or is undefined, the result of the evaluation is false. This result is regardless of the state of the object.
andnot	(Optional) Specifies that if event 1 occurs the action is executed, and if event 2 and event 3 occur together the action is not executed.
and	(Optional) Specifies that if event 1 occurs the action is executed, and if event 2 and event 3 occur together the action is executed.
or	(Optional) Specifies that if event 1 occurs the action is executed, or else if event 2 and event 3 occur together the action is executed.

Command Default

Command Modes

Trigger applet configuration (config-applet-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

After you enter the trigger statement, the router enters trigger applet configuration mode. The correlate statement and up to eight attribute statements can be specified in trigger applet configuration mode. These statements are used to create a complex event correlation using the participating event statements to a maximum of eight statements. The correlate statement allows Boolean logic to be used to relate events and tracked objects. When the result of the correlate evaluation is true, the trigger criteria are applied. The correlation occurs from left to right taking into account the attribute statement conditions for the event.

Examples

The following example, shows how to configure a correlate statement after entering trigger applet configuration mode. This applet will run if the write memory or copy run start command occurs within 60 seconds of CRON specified time.

Router(config)# event manager applet trigger
Router(config-applet)# event tag e1 cli pattern "write mem.*" sync yes
Router(config-applet)# event tag e2 cli pattern "copy run start" sync yes
Router(config-applet)# trigger occurs 1 period-start 0-59/1 0-23/1 * * 0-7 period 60
Router(config-applet-trigger)# correlate event e1 or event e2
Router(config-applet-trigger)# attribute tag e1 occurs 1
Router(config-applet-trigger)# attribute tag e2 occurs 1
Router(config-applet-trigger)# action 1.0 syslog msg "$_cli_msg Command Executed"
Router(config-applet-trigger)# set 2.0 _exit_status 1

In the following example, the applet will run if either the write memory or copy run start command occurs and any syslog message that contains the string "hello" occurs within 60 seconds of any valid CRON specified time.

Router(config)# event manager applet trigger
Router(config-applet)# event tag e1 cli pattern "write mem.*" sync yes
Router(config-applet)# event tag e2 cli pattern "copy run start" sync yes
Router(config-applet)# event tag e3 syslog pattern "hello"
Router(config-applet)# trigger occurs 1 period-start 0-59/1 0-23/1 * * 0-7 period 60
Router(config-applet-trigger)# correlate event e1 or event e2 and event e3
Router(config-applet-trigger)# attribute tag e1 occurs 1
Router(config-applet-trigger)# attribute tag e2 occurs 1
Router(config-applet-trigger)# attribute tag e3 occurs 1
Router(config-applet-trigger)# action 1.0 syslog msg "$_cli_msg Command Executed"
Router(config-applet-trigger)# set 2.0 _exit_status 1

In the following example, the applet will run when the write memory command is entered and the tracked object 10 is set:

Router(config)# event manager applet trigger
Router(config)# event tag e1 cli pattern "write mem.*" sync yes
Router(config)# trigger occurs 1
Router(config-applet-trigger)# correlate event e1 and track 10
Router(config-applet-trigger)# attribute tag e1 occurs 1

Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

Specific bulk statistics configurations are identified with a name, as specified in the snmp mib bulkstat transfer command. The enable command (in Bulk Statistics Transfer configuration mode) begins the periodic MIB data collection and transfer process.

Collection (and subsequent file transfer) will start only if this command is used. Conversely, the no enablecommand will stop the collection process. Subsequently, issuing the enablecommand will start the operations again.

Each time the collection process is started using the enable command, data is collected into a new bulk statistics file. When the no enable command is used, the transfer process for any collected data will immediately begin (in other words, the existing bulk statistics file will be transferred to the specified management station).

To successfully enable a bulk statistics configuration, at least one schema with a non-zero number of objects must be configured.

Examples

The following example shows the bulk statistics transfer configuration named bulkstat1 as enabled:

Router(config)# snmp mib bulkstat transfer bulkstat1
Router(config-bulk-tr)# schema ATM2/0-IFMIB
Router(config-bulk-tr)# url primary ftp://user:pswrd@host/folder/bulkstat1

Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

Note

In Cisco IOS Release 12.0(24)S, only the schemaASCII format is supported. This command will not change the file format in that release.

The bulk statistics data file (VFile) contains two types of fields: tags and data. Tags are used to set off data to distinguish fields of the file. All other information is in data fields.

For the bulkASCII and bulkBinary formats, periodic polling enables data for a single data group (object list) to be collected more than once in the same VFile. Each such instance of a data group can be treated as a different "table" type.

Every object and table tag contains an additional sysUpTime field. Similarly each row tag contains the value of the sysUpTime when the data for that row was collected. The sysUpTime provides a time stamp for the data.

For additional information about the structures of the bulk statistics data file formats, see the definitions in the CISCO-DATA-COLLECTION-MIB.

Examples

In the following example, the bulk statistics data file is set to schemaASCII:

Router(config)# snmp mib bulkstat transfer bulkstat1
 
Router(config-bulk-tr)# schema ATM2/0-IFMIB
 
Router(config-bulk-tr)# url primary ftp://user:pswrd@host/folder/bulkstat1

instance (MIB)

To configure the MIB object instances to be used in a bulk statistics schema, use the instancecommand in Bulk Statistics Schema configuration mode. To remove a Simple Network Management Protocol (SNMP) bulk statistics object list, use the no form of this command.

instance {exact | wild} {interface interface-id [sub-if] | oid oid}

no instance

Syntax Description

exact	Indicates that the specified instance (interface, controller, or object identifier [OID]), when appended to the object list, is the complete OID to be used in this schema.
wild	Indicates that all instances that fall within the specified interface, controller, or OID range should be included in this schema.
interface	Specifies a specific interface or group of interfaces for the schema.
interface-id	Interface name and number for a specific interface or group of interfaces.
sub-if	(Optional) Specifies that the object instances should be polled for all subinterfaces of the specified interface or controller in addition to the object instances for the main interface.

12.2(33)SB	This command was integrated into Cisco IOS Release 12.2(33)SB.
Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

The instance command specifies the instance information for objects in the schema being configured. 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 associated object list. In other words, the schema object-list when combined with the schema instance specifies a complete MIB object identifier.

The instance exact command indicates that the specified instance, when appended to the object list, is the complete OID.

The instance wild command indicates that all subindices of the specified OID belong to this schema. In other words, the wild keyword allows you to specify a partial, wildcarded instance.

Instead of specifying an OID, you can specify a specific interface. The interface interface-id keyword and argument allow you to specify an interface name and number (for example, FastEthernet 0) instead of specifying the ifIndex OID for the interface.

The optional sub-if keyword, when added after specifying an interface or controller, includes the ifIndexes for all subinterfaces of the interface you specified.

Only one instance command can be configured per schema.

Examples

The following example shows how to configure the router to collect bulk statistics for the ifInOctets object (from the IF-MIB) for Fast Ethernet interface 3/0. In this example, 3 is the ifIndex instance for Fast Ethernet interface 3/0. The instance (3) when combined with the object list (ifIndex; 1.3.6.1.2.1.2.2.1.1) translates to the OID 1.3.6.1.2.1.2.2.1.1.3.

Router# configure terminal
Router(config)# snmp mib bulkstat object-list E0InOctets
! The following command specifies the object 1.3.6.1.2.1.2.2.1.1.3 (ifIndex)
Router(config-bulk-objects)# add ifIndex
Router(config-bulk-objects)# exit
Router(config)# snmp mib bulkstat schema E0
Router(config-bulk-sc)# object-list E0InOctets
! The following command is equivalent to "instance exact oid 3".
Router(config-bulk-sc)# instance exact interface FastEthernet 3/0
Router(config-bulk-sc)# exit
Router(config)# snmp mib bulkstat transfer bulkstat1
Router(config-bulk-tr)# schema E0
Router(config-bulk-tr)# url primary ftp://user:password@host/ftp/user/bulkstat1
Router(config-bulk-tr)# url secondary tftp://user@host/tftp/user/bulkstat1

Usage Guidelines

The poll-interval command sets how often the MIB instances specified by the schema and associated object list are to be polled. Collected data is stored in the local bulk statistics file for later transfer.

Examples

In the following example, the polling interval for bulk statistics collection is set to once every 3 minutes in the schema called FastEthernet2/1-CAR:

Router(config)# snmp mib bulkstat schema FastEthernet2/1-CAR
 
Router(config-bulk-sc)# object-list CAR-mib
 
Router(config-bulk-sc)# poll-interval 3
 
Router(config-bulk-sc)# instance wildcard oid 3.1
 
Router(config-bulk-sc)# exit

Command	Description
snmp mib bulkstat schema	Names a bulk statistics schema and enters Bulk Statistics Schema configuration mode.

prefix object

To enable the application to determine the object based on instance indexing, use the prefix objectcommand in the expression object configuration mode.

prefix object object-id

Syntax Description

object-id

Object identifier of an object.

Command Default

No object is prefixed by default.

Command Modes

Expression object configuration (config-expression-object)

Command History

Release	Modification
12.4(20)T	This command was introduced.

Usage Guidelines

The prefix objectcommand enables the application to determine an object according to the instance indexing. The instance index is used in expValueTable. The prefix object command eliminates the need to scan expObjectTable to determine a prefix, thereby easing the burden of an application.

Examples

The following example shows how to specify a prefix object:

Router(config)# snmp mib expression owner John name ExpressionA
Router(config-expression)# object
Router(config-expression-object)# prefix object 0.0.6
Router(config-expression-object)#

Related Commands

Command	Description
snmp mib expression owner	Specifies an expression owner.

retain

To configure the retention interval for bulk statistics files, use the retain command in Bulk Statistics Transfer configuration mode. To remove a previously configured retention interval from the configuration, use the no form of this command.

retain minutes

no retain

Syntax Description

minutes

Length of time, in minutes, that the local bulk statistics file should be kept in system memory (the retention interval). The valid range is 0 to 20000. The default is 0.

Command Default

The bulk statistics file retention interval is 0 minutes.

Command Modes

Bulk Statistics Transfer configuration (config-bulk-tr)

Command History

Release	Modification
12.0(24)S	This command was introduced.
12.3(2)T	This command was integrated into Cisco IOS Release 12.3(2)T.
12.2(25)S	This command was integrated into Cisco IOS Release 12.2(25)S.
12.2(33)SRA	This command was integrated into Cisco IOS Release 12.2(33)SRA.
12.2(33)SXH	This command was integrated into Cisco IOS Release 12.2(33)SXH.
12.2(33)SB	This command was integrated into Cisco IOS Release 12.2(33)SB.
Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

This command specifies how long the bulk statistics file should be kept in system memory, in minutes, after the completion of the collection interval and a transmission attempt is made. The default value of zero (0) indicates that the file will be deleted immediately from local memory after a successful transfer.

If the retry command is used, you should configure a retention interval greater than 0. The interval between retries is the retention interval divided by the retry number. For example, if retain 10 and retry 2 are configured, retries will be attempted once every 5 minutes. Therefore, if the retain command is not configured (retain default is 0), no retries will be attempted.

Examples

In the following example, the bulk statistics transfer retention interval is set to 10 minutes:

Router(config)# snmp mib bulkstat transfer bulkstat1
Router(config-bulk-tr)# schema ATM2/0-IFMIB
Router(config-bulk-tr)# url primary ftp://user:pswrd@host/folder/bulkstat1
Router(config-bulk-tr)# retry 2
Router(config-bulk-tr)# retain 10
Router(config-bulk-tr)# exit

retry (bulkstat)

To configure the number of retries that should be attempted for a bulk statistics file transfer, use the retry command in Bulk Statistics Transfer configuration mode. To return the number of bulk statistics retries to the default, use the no form of this command.

retry number

no retry

Syntax Description

number

Number of transmission retries. The valid range is from 0 to 100.

Command Default

No retry attempts are made.

Command Modes

Bulk Statistics Transfer configuration (config-bulk-tr)

Command History

Release	Modification
12.0(24)S	This command was introduced.
12.3(2)T	This command was integrated into Cisco IOS Release 12.3(2)T.

12.2(33)SB	This command was integrated into Cisco IOS Release 12.2(33)SB.
Cisco IOS XE Release 2.1	This command was integrated into Cisco IOS Release XE 2.1.

Usage Guidelines

If an attempt to send the bulk statistics file fails, the system can be configured to attempt to send the file again using the retry command. One retry includes an attempt first to the primary destination and then, if the transmission fails, to the secondary location; for example, if the retry value is 1, an attempt will be made first to the primary URL, then to the secondary URL, then to the primary URL again, and then to the secondary URL again.

If the retry command is used, you should also use the retaincommand to configure a retention interval greater than 0. The interval between retries is the retention interval divided by the retry number. For example, if retain 10 and retry 2 are configured, retries will be attempted once every 5 minutes. Therefore, if the retain command is not configured (or the retain 0 command is used) no retries will be attempted.

Examples

In the following example, the number of retries for the bulk statistics transfer is set to 2:

Router(config)# snmp mib bulkstat transfer bulkstat1
Router(config-bulk-tr)# schema ATM2/0-IFMIB
Router(config-bulk-tr)# url primary ftp://user:pswrd@host/folder/bulkstat1
Router(config-bulk-tr)# retry 2
Router(config-bulk-tr)# retain 10
Router(config-bulk-tr)# exit
