Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Regular expressions have two constraints:

Regular expressions must always be entered within double quotes to ensure that the CLI interprets each character correctly.
All characters that are part of a regular expression are considered regular characters with no special meaning. In order to enter special characters, such as "\" or "?," they must be preceded by the backslash character "\." For example, to enter the regular expression ([A-Z][A-Z0-9]*)\b[^>]*>(.*?)</\1, you would enter ([A-Z][A-Z0-9]*)\\b[^>]*>(.*\?)</\\1.

Refer to the Understanding Regular Expressions, Special Characters, and Patterns module in for more information regarding regular expressions.

When using the subset or regular-expression keywords, the actual display might not match the configuration if there are higher priority subset-number values that actually apply to the interface. This can happen for a set of interfaces that are included in two or more configured regular expressions or where an individual interface configuration is enabled.

show snmp mib

To display a list of MIB module object identifiers (OIDs) registered on the system, use the show snmp mib command in

EXEC

mode.

show snmp mib [object-name | dll]

Syntax Description


`object-name`	(Optional) Specific MIB object identifier or object name.
dll	(Optional) Displays a list of all MIB DLL filenames and the OID supported by each DLL filename on the system.

Command Default

Command Modes

EXEC

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Use the show snmp mib command to display a list of the MIB module instance identifiers registered on the system.

Although the show snmp mib command can be used to display a list of MIB 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 is intended only for network managers who are familiar with Abstract Syntax Notation One (ASN.1) syntax and the Structure of Management Information (SMI) of Open Systems Interconnection (OSI) Reference Model.

SNMP management information is viewed as a collection of managed objects residing in a virtual information store termed the MIB. Collections of related objects are defined in MIB modules. These modules are written using a subset of ASN.1 termed the SMI.

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.

Use the detailed keyword to display a list of the MIB module instance identifiers registered on the system. The output displays additional details, such as DLL and configuration information.

Use the dll keyword to display a list of the MIB modules loaded into the agent. This command can be used to find the supported MIBs.

Note

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

Usage Guidelines

Use the snmp-server community-map command to map an SNMPv1 or SNMPv2c community name to one or more of the following:

context name—Maps a community name to a specific SNMP context name. This allows MIB instances in an SNMP context to be accessed through SNMPv1 or SNMPv2c using this community name.
security name—By default, the community name is used to authenticate SNMPv1 and SNMPv2c. Configure a security name for a community name to override the default and authenticate SNMP with the security name.
target—Target list identifies a list of valid hosts from which SNMP access can be made using a specific security name. When such mapping is done for a particular community name, SNMP access is allowed only from hosts included in the target list.

Use the clear keyword to specify that the clear text community string you enter is displayed encrypted in the show running command output. To enter an encrypted string, use the encrypted keyword. To enter a clear text community string that is not encrypted by the system, use neither of these keywords.

Usage Guidelines

A device can support multiple instances of a logical network entity, such as protocol instances or VRFs. Most existing MIBs cannot distinguish between these multiple logical network entities. For example, the original OSPF-MIB assumes a single protocol instance on a device, but you can now configure multiple OSPF instances on a device.

The snmp-server context mapping command maps a context to a protocol instance, topology or VRF logical entity.

Note

The snmp-server context mapping command does not work for OSPF and OSPFv3. Refer to the snmp context commands.

Release 6.2.3	This command was introduced.

Usage Guidelines

To drop an unknown engine-id report, you can either configure IPv4/IPv6 ACL name or both. When router is polled with wrong engine-id or no engine-id during a snmpv3 packet exchange, the unknown engine-id report will be sent based on the ACL policy that is configured.

Unknown engine-id reports will be sent only to polling station addresses that are permitted by ACL.

Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

This table describes the default values for the different views:

Table 7. snmp-server group Default Descriptions
Default	Definition
read `view`	Assumed to be every object belonging to the Internet (1.3.6.1) object identifier (OID) space, unless the user uses the read option to override this state.
write `view`	Nothing is defined for the write view (that is, the null OID). You must configure write access.
notify `view`	Nothing is defined for the notify view (that is, the null OID). If a view is specified, any notifications in that view that are generated are sent to all users associated with the group (provided an SNMP server host configuration exists for the user).

Configuring Notify Views

Do not specify a notify view when configuring an SNMP group for the following reasons:

The snmp-server host command autogenerates a notify view for the user, and then adds it to the group associated with that user.
Modifying the notify view of the group affects all users associated with that group.

The notify view option is available for two reasons:

If a group has a notify view that is set using SNMP, you may need to change the notify view.
The snmp-server host command may have been configured before the snmp-server group command. In this case, reconfigure the snmp-server host command or specify the appropriate notify view.

Instead of specifying the notify view for a group as part of the snmp-server group command, use the following commands in global configuration mode:

snmp-server user —Configures an SNMP user.
snmp-server group —Configures an SNMP group, without adding a notify view.
snmp-server host —Autogenerates the notify view by specifying the recipient of a trap operation.

Working with Passwords and Digests

No default values exist for authentication or privacy algorithms when this command is configured. In addition, no default passwords exist. The minimum length for a password is one character, although we recommend using eight characters for security. A plain-text password or localized Message Digest 5 (MD5) password can be specified. Forgotten passwords cannot be recovered, and the user must be reconfigured.

SNMP Contexts

SNMP contexts provide Virtual Private Network (VPN) users with a secure way of accessing MIB data. When a VPN is associated with a context, that VPN’s specific MIB data 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 remove the specified host, use the no form of this command.

snmp-server host address [clear | encrypted] [informs] [traps] [version {1 | 2c | 3 {auth | noauth | priv}}] community-string [udp-port port] [notification-type]

no snmp-server host address [clear | encrypted] [informs] [traps] [version {1 | 2c | 3 {auth | noauth | priv}}] community-string [udp-port port] [notification-type]

Syntax Description


`address`	Name or IP address of the host (the targeted recipient).
clear	(Optional) Specifies that the `community-string` argument is clear text.
encrypted	(Optional) Specifies that the `community-string` argument is encrypted text.
informs	(Optional) Specifies to send inform messages to this host.
traps	(Optional) Specifies that notifications should be sent as traps. This is the default.
version	(Optional) Specifies the version of the SNMP used to send the traps.
1	Specifies SNMPv1, the default.
2c	Specifies SNMPv2C.
3	Specifies SNMPv3. Version 3 is the most secure model because it allows packet encryption. If you specify the SNMPv3 keyword, you must specify the security level.
auth	Enables Message Digest 5 (MD5) algorithm and Secure Hash Algorithm (SHA) packet authentication.
noauth	Specifies that the noAuthNoPriv security level applies to this host. This is the default security level for SNMPv3.
priv	Enables Data Encryption Standard (DES) packet encryption (also called “privacy”).
`community-string`	Password-like community string sent with the notification operation. We recommend defining this string using the snmp-server community command prior to using the snmp-server host command.
udp-port `port`	(Optional) Specifies the User Datagram Protocol (UDP) port of the host to use. Range is from 1 to 65535. The default UDP port is 161.
`notification-type`	(Optional) Type of notification to be sent to the host. If no type is specified, all available notifications are sent. The notification type can be one or more of these keywords: bgp —Enables SNMP Border Gateway Protocol Version 4 (BGPv4) traps. config —Controls configuration notifications, as defined in the CISCO-CONFIG-MAN-MIB (enterprise 1.3.6.1.4.1.9.9.43.2). The notification type is (1) ciscoConfigManEvent. copy-complete —Enables CISCO-CONFIG-COPY-MIB ccCopyCompletion traps. entity —Controls Entity MIB modification notifications. This notification type is defined in the ENTITY-MIB (enterprise 1.3.6.1.2.1.47.2) as: (1) entConfigChange. fabric —Enables SNMP fabric traps. fru-ctrl —Enables SNMP entity field-replaceable unit (FRU) control traps. mpls —Enables SNMP Multiprotocol Label Switching (MPLS) traps. sensor —Enables SNMP entity sensor traps. snmp —Enables SNMP traps. syslog —Controls error message notifications (Cisco-syslog-MIB). Specify the level of messages to be sent with the logging history command.

Command Default

This command is disabled by default. No notifications are sent.

The default UDP port is 161.

When this command is entered without keywords, the default is to send all trap types to the host.

If no version keyword is entered, the default is version 1.

If version 3 is specified, but the security level is not specified, the default security level is noauth.

Command Modes

Global configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

SNMP notifications can be sent as traps. Traps are unreliable because the receiver does not send acknowledgments when it receives traps. The sender cannot determine if the traps were received. Traps are discarded as soon as they are sent. Traps are also sent only once.

When the snmp-server host command is not entered, no notifications are sent. To configure the device to send SNMP notifications, configure at least one snmp-server host command. When the command is entered without keywords, all trap types are enabled for the host.

To enable multiple hosts, issue a separate snmp-server host command for each host. You can specify multiple notification types in the command for each host.

When multiple snmp-server host commands are given for the same host and kind of notification (trap), each succeeding snmp-server host command overwrites the previous command. Only the last snmp-server host command is in effect. For example, if an snmp-server host command with the traps keyword is entered for a host and then another command with the traps keyword is entered for the same host, the second command replaces the first.

Either a host name or IP address can be used to specify the host. Both IPv4 and IPv6 IP address formats are supported.

The snmp-server host command is used with the snmp-server engineid command. Use the snmp-server traps command to specify which SNMP notifications are sent globally. For a host to receive most notifications, at least one snmp-server traps command and the snmp-server host command for that host must be enabled.

However, some notification types cannot be controlled with the snmp-server traps command. For example, some notification types are always enabled. Other notification types are enabled by a different command.

The availability of a notification-type depends on the device type and Cisco software features supported on the device.

To display which notification types are available on the system, use the question mark (? ) online help function at the end of the snmp-server host command.

The no snmp-server host command used with no keywords disables traps.

Use the clear keyword to specify that the clear text community string you enter is displayed encrypted in the show running command output. To enter an encrypted string, use the encrypted keyword. To enter a clear text community string that is not encrypted by the system, use neither of these keywords.

If the informs keyword is used, the SNMP version can be only SNMPv2C or SNMPv3.

Examples

This example shows how to send RFC 1157 SNMP traps to the host specified by the name myhost.cisco.com. Other traps are enabled, but only SNMP traps are sent because only the snmp keyword is specified in the snmp-server host command. The community string is defined as comaccess.


Router(config)# snmp-server traps
Router(config)# snmp-server host myhost.cisco.com comaccess snmp

This example shows how to send the SNMP traps to address 172.30.2.160:


Router(config)# snmp-server traps snmp 
Router(config)# snmp-server host 172.30.2.160 public snmp

This example shows how to enable the router to send all traps to the host, myhost.cisco.com, using the community string public:


Router(config)# snmp-server traps 
Router(config)# snmp-server host myhost.cisco.com public

This example shows how to prevent traps from being sent to any host. The BGP traps are enabled for all hosts, but only the configuration traps are enabled to be sent to a host.


Router(config)# snmp-server traps bgp
Router(config)# snmp-server host hostabc public config

Global configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The subset-number argument is used to set the priority for an interface that matches more than one configured regular expressions. Lower values of the subset-number have a higher priority. If a single interface becomes part of a multiple-interface configured regular expression, the configuration with the lower subset-number value is applied.

Regular expressions have two constraints:

Regular expressions must always be entered within double quotes to ensure that the CLI interprets each character correctly.
All characters that are part of a regular expression are considered regular characters with no special meaning. In order to enter special characters, such as "\" or "?," they must be preceded by the backslash character "\." For example, to enter the regular expression ([A-Z][A-Z0-9]*)\b[^>]*>(.*?)</\1, you would enter ([A-Z][A-Z0-9]*)\\b[^>]*>(.*\?)</\\1.

Refer to the Understanding Regular Expressions, Special Characters, and Patterns module in for more information regarding regular expressions.

Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

Note

A maximum of 100 interfaces can be monitored for congestion.

Congestion configurations using the snmp-server mibs eventmib congestion-control command cannot be modified using SNMP SET and vice versa.

When the congestion between two intervals increases above the upper-threshold argument, an mteTriggerRising SNMP trap is generated. This trap is not generated until the congestion drops below the lower threshold and then rises above the upper threshold.

When the congestion between two intervals falls below the lower-threshold argument, and an SNMP mteTriggerRising trap was generated previously, an SNMP mteTriggerFalling trap is generated. The mteTriggreRising trap is not generated until the congestion goes above the upper threshold and then falls back below the lower threshold.

The lower-threshold value (falling) should be set to a value less than or equal to the upper-threshold value (rising).

The snmp-server mibs eventmib congestion-control command is configured on a specific interface and is supported on the following cards:

8-port 10 Gigabit Ethernet PLIM
16-port OC-48c/STM-16 POS/DPT PLIM

snmp-server traps snmp [authentication | coldstart | linkdown | linkup | warmstart]

no snmp-server traps snmp [authentication | coldstart | linkdown | linkup | warmstart]

Syntax Description


authentication	(Optional) Controls the sending of SNMP authentication failure notifications.
linkup	(Optional) Controls the sending of SNMP linkUp notifications
linkdown	(Optional) Controls the sending of SNMP linkDown notifications
coldstart	(Optional) Controls the sending of SNMP coldStart notifications.
warmstart	(Optional) Controls the sending of SNMP warmStart notifications.

Command Default

SNMP notifications are disabled by default.

Command Modes

Global configuration

Command History


Release	Modification
Release 7.0.12	This command was introduced.

Usage Guidelines

The snmp-server traps snmp command is used with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications.

The optional authentication keyword controls the sending of SNMP authentication failure notifications. In order to send notifications, you must configure at least one snmp-server host command. An authentication Failure (4) trap signifies that the sending device is the addressee of a protocol message that is not properly authenticated. The authentication method depends on the version of SNMP being used. For SNMPv1 or SNMPv2, authentication failure occurs for packets with an incorrect community string. For SNMPv3, authentication failure occurs for packets with an incorrect Secure Hash Algorithm (SHA) or Message Digest 5 (MD5) authentication key or for a packet that is outside the authoritative SNMP engine’s window, for example, the packets that are configured outside access lists or time ranges. In such an instance, only a report Protocol Data Unit (PDU) is generated, and authentication failure traps are not generated.

The optional linkup keyword controls the sending of SNMP linkUp notifications. The linkUp(3) trap signifies that the sending device recognizes one of the communication links represented in the agent's configuration coming up.

The optional linkdown keyword controls the sending of SNMP linkDown notifications. The linkDown(2) trap signifies that the sending device recognizes a failure in one of the communication links represented in the agent's configuration.

The snmp-server traps snmp command with the linkup or linkdown keywords globally enables or disables SNMP linkUp and linkDown traps. After enabling either of these traps globally, you can enable or disable these traps on specific interfaces using the no notification linkupdown disable command in interface configuration mode. According to RFC 2863, linkUp and linkDown traps are enabled for interfaces that do not operate on top of any other interface (as defined in the ifStackTable), and are disabled otherwise. This means that you do not have to enable linkUp and linkdown notifications on such interfaces. However, linkUp and linkDown notifications will not be sent unless you enable them globally using the snmp-server traps snmp command.

The optional coldstart keyword controls the sending of SNMP coldStart notifications. The coldStart(0) trap signifies that the sending device is reinitializing itself such that the agent's configuration or the protocol entity implementation may be altered.

The optional warmstart keyword controls the sending of SNMP coldStart notifications. The warmStart(1) trap signifies that the sending device is reinitializing itself such that neither the agent configuration nor the protocol entity implementation is altered.

all: Predefined view indicating that a user can see all objects.
CfgProt: Predefined view indicating that a user can see all objects except the SNMPv3 configuration tables.
vacmViewTreeFamilyEntry: Predefined view indicating that a user can see the default configuration of vacmViewTreeFamilyEntry.

The predefined views supported on Cisco IOS XR software, however, do not match the predefined views specified in RFC 3415.

Examples

This example creates a view that includes all objects in the MIB-II subtree:


RP/0/RP0/CPU0:router(config)# snmp-server view mib2 1.3.6.1.2.1 included

This example shows how to create a view that includes all objects in the MIB-II system group and all objects in the Cisco enterprise MIB:


RP/0/RP0/CPU0:router(config)# snmp-server view view1 1.3.6.1.2.1.1 included
RP/0/RP0/CPU0:router(config)# snmp-server view view1 1.3.6.1.4.1.9 included

This example shows how to create a view that includes all objects in the MIB-II system group except for sysServices (System 7) and all objects for interface 1 in the MIB-II interfaces group:


RP/0/RP0/CPU0:router(config)# snmp-server view view1 1.3.6.1.2.1.1 included
RP/0/RP0/CPU0:router(config)# snmp-server view view1 1.3.6.1.2.1.1.7 excluded
RP/0/RP0/CPU0:router(config)# snmp-server view view1 1.3.6.1.2.1.2.2.1.*.1 included

snmp-server vrf

To configure the VPN routing and forwarding (VRF) properties of Simple Network Management Protocol (SNMP), use the snmp-server vrf command in

global configuration

mode. To remove the configuration, use the no form of this command.

snmp-server vrf vrf-name [host address [clear | encrypted] [traps] [version {1 | 2c | 3 security-level}] community-string [udp-port port]] [context context-name]

no snmp-server vrf vrf-name

Syntax Description


`vrf-name`	Name of the VRF.
host `address`	(Optional) Specifies the name or IP address of the host (the targeted recipient).
clear	(Optional) Specifies that the `community-string` argument is clear text.
encrypted	(Optional) Specifies that the `community-string` argument is encrypted text.
traps	(Optional) Specifies that notifications should be sent as traps. This is the default.
version {1 \| 2c \| 3}	(Optional) Specifies the version of the SNMP used to send the traps. The default is SNMPv1. When the version keyword is used, one of these keywords must be specified: 1—SNMPv1 2c—SNMPv2C 3—SNMPv3
`security-level`	(Optional) Security level for SNMPv3. Options are: auth—authNoPriv noauth—noAuthNoPriv priv—authPriv
`community-string`	Specifies the community string for SNMPv1 and SNMPv2, or the SNMPv3 user.
udp-port `port`	(Optional) Specifies the UDP port to which notifications should be sent.
context `context-name`	(Optional) Name of the context that must be mapped to VRF identified by value of the `vrf-name` argument.

Usage Guidelines

Use this command to enter SNMP VRF configuration mode and configure an SNMP notification recipient on a VRF. You can also map a VRF to an SNMP context.

SNMP notification recipient that is reachable by way of a VRF can be configured. Notification is forwarded to the recipient represented by its address using the routing table instance identified by the VRF name.

The address argument can be either a host name or an IP address.

Use the clear keyword to specify that the clear text community string you enter is displayed encrypted in the show running command output. To enter an encrypted string, use the encrypted keyword. To enter a clear text community string that is not encrypted by the system, use neither of these keywords.

An SNMP context identified by the value of the context-name argument can be mapped to a VRF in this mode. This context must be created using snmp-server context command.
