Configuring SNMP on the Cisco IME Server


SNMP version 3 provides security features such as authentication (verifying that the request comes from a genuine source), privacy (encryption of data), authorization (verifying that the user allows the requested operation), and access control (verifying that the user has access to the objects requested.) To prevent SNMP packets from being exposed on the network, you can configure encryption with SNMPv3.

This chapter describes how to configure SNMP v3, so the network management system can monitor Cisco IME and contains the following topics:

Configuration Steps
Related Procedures and Topics

Step 1 

Install and configure the SNMP NMS.

SNMP product documentation that supports the NMS

Step 2 

In the CLI, verify that the system started the SNMP services, including:

SNMP Master Agent

Native Agent

System Application Agent

Cisco Syslog Agent

MIB2 Agent

Host Resources Agent

At the Cisco IME command line, type the following command:

utils service list

Step 3 

Configure the SNMP user.

SNMP Users

Step 4 

Configure the notification destination for traps or informs.

SNMP Trap Notification Destinations

SNMP Inform Notification Destination

Step 5 

Configure the system contact and location for the MIB2 system group.

MIB2 System Group

Step 6 

Configure trap settings for CISCO-SYSLOG-MIB.

Use these guidelines to configure CISCO-SYSLOG-MIB trap settings on your system:

Set clogsNotificationEnabled (1.3.6.1.4.1.9.9.41.1.1.2) to true by using the SNMP Set operation; for example, use the net-snmp set utility to set this OID to true from the linux command line using: snmpset -c <community string> -v2c <transmitter ipaddress> 1.3.6.1.4.1.9.9.41.1.1.2.0 i 1

You can also use any other SNMP management application for the SNMP Set operation.

Set clogMaxSeverity (1.3.6.1.4.1.9.9.41.1.1.3) value by using the SNMP Set operation; for example, use the net-snmp set utility to set this OID value from the linux command line using: snmpset -c public -v2c 1<transmitter ipaddress> 1.3.6.1.4.1.9.9.41.1.1.3.0 i <value>

Enter a severity number for the <value> setting. Severity values increase as severity decreases. A value of 1 (Emergency) indicates highest severity, and a value of 8 (Debug) indicates lowest severity. Syslog agent ignores any messages greater than the value that you specify; for example, to trap all syslog messages, use a value of 8.

Step 7 

Restart the SNMP Master Agent service. (Optional)

Tip The system automatically restarts the SNMP Master Agent after you execute the utils snmp config commands.

At the Cisco IME command line, type the following command:

utils service start SNMP Master Agent

Step 8 

On the NMS, configure the Cisco IME trap parameters.

SNMP Management Information Base (MIB)

SNMP allows access to Management Information Base (MIB), which is a collection of information that is organized hierarchically. MIBs comprise managed objects, which are identified by object identifiers. A MIB object, which contains specific characteristics of a managed device, comprises one or more object instances (variables).

The SNMP interface provides these Cisco Standard MIBs:

CISCO-CDP-MIB

CISCO-SYSLOG-MIB

The Simple Network Management Protocol (SNMP) extension agent resides in the server and exposes the CISCO-CCM-MIB, which provides detailed information about devices that are known to the server. In the case of a cluster configuration, the SNMP extension agent resides in each server in the cluster. The CISCO-CCM-MIB provides device information such as device registration status, IP address, description, and model type for the server (not the cluster, in a configuration that supports clusters).

The SNMP interface also provides these Industry Standard MIBs:

SYSAPPL-MIB

MIB-II (RFC 1213)

HOST-RESOURCES-MIB

For vendor-specific supported hardware MIBS, refer to the "Vendor-Specific MIBs" section.

Cisco IME SNMP Interface supports the following MIBs.

CISCO-CDP-MIB

Use the Cisco Unified Communications Manager CDP subagent to read the Cisco Discovery Protocol MIB, CISCO-CDP-MIB. This MIB enables Cisco IME to advertise itself to other Cisco devices on the network.

The CDP subagent implements the CDP-MIB. The CDP-MIB contains the following objects:

cdpInterfaceIfIndex

cdpInterfaceMessageInterval

cdpInterfaceEnable

cdpInterfaceGroup

cdpInterfacePort

cdpGlobalRun

cdpGlobalMessageInterval

cdpGlobalHoldTime

cdpGlobalLastChange

cdpGobalDeviceId

cdpGlobalDeviceIdFormat

cdpGlobalDeviceIdFormatCpd

SYSAPPL-MIB

Use the System Application Agent to get information from the SYSAPPL-MIB, such as installed applications, application components, and processes that are running on the system.

System Application Agent supports the following object groups of SYSAPPL-MIB:

sysApplInstallPkg

sysApplRun

sysApplMap

sysApplInstallElmt

sysApplElmtRun

MIB-II

Use MIB2 agent to get information from MIB-II. The MIB2 agent provides access to variables that are defined in RFC 1213, such as interfaces, IP, and so on, and supports the following groups of objects:

system

interfaces

at

ip

icmp

tcp

udp

snmp

HOST-RESOURCES MIB

Use Host Resources Agent to get values from HOST-RESOURCES-MIB. The Host Resources Agent provides SNMP access to host information, such as storage resources, process tables, device information, and installed software base. The Host Resources Agent supports the following groups of objects:

hrSystem

hrStorage

hrDevice

hrSWRun

hrSWRunPerf

hrSWInstalled

CISCO-SYSLOG-MIB

Syslog tracks and logs all system messages, from informational through critical. With this MIB, network management applications can receive syslog messages as SNMP traps:

The Cisco Syslog Agent supports trap functionality with the following MIB objects:

clogNotificationsSent

clogNotificationsEnabled

clogMaxSeverity

clogMsgIgnores

clogMsgDrops

Vendor-Specific MIBs

The following MIBs exist on various Cisco MCS, depending on vendor and model number. To query these MIBS, you can use the standard MIB browsers that the hardware vendors develop; for example, HP Systems Insight Manager (SIM) and IBM Director Server+Console. For information on using the MIB browsers, refer to the documentation that the hardware vendor provides.

To review the vendor-specific MIB information, see the following tables:
