•Ipswitch WhatsUp Gold

•HP OpenView Network Node Manager

•CiscoWorks

Net-SNMP

Net-SNMP Version 5.1.2 provides the following tools and libraries:

•An extensible agent

•An SNMP library

•Tools to request or set information from SNMP agents

•Tools to generate and handle SNMP traps

You can download the Net-SNMP network management tool from the following URL:

http://sourceforge.net/projects/net-snmp/

This section includes the following topics:

•Polling a MIB

•Sending a Trap

Polling a MIB

To poll a MIB, after you have finished configuring the adaptive security appliance, run the snmpwalk command from the NMS to the adaptive security appliance:

Note No specific configuration is required for Net-SNMP on Linux when you run the snmpwalk command.
[root@iLinux2 ~]# snmpwalk -v3 -u md5des -l authPriv -a MD5 -A mysecretpass -x des -X 
passphrase 10.31.8.254 1.3.6.1.2.1.1
The following is sample output from the snmpwalk command:
SNMPv2-MIB::sysDescr.0 = STRING: Cisco Adaptive Security Appliance Version 8.2(0)227
SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.9.1.915
SNMPv2-MIB::sysUpTime.0 = Timeticks: (486600) 1:21:06.00
SNMPv2-MIB::sysContact.0 = STRING: admin admin
SNMPv2-MIB::sysName.0 = STRING: ciscoasa
SNMPv2-MIB::sysLocation.0 = STRING: sjc - 190 W Tasman Drive, San Jose, CA 95134
 USA
SNMPv2-MIB::sysServices.0 = INTEGER: 4
Sending a Trap

When the adaptive security appliance sends a trap, it is authoritative, which means that the user created within the snmptrapd command must be associated with the EngineID sending the trap.

To establish this association, perform the following steps:

Step 1 In the /var/net-snmp/snmptrapd.conf file, enter the following statement:
createUser -e ENGINEID myuser authentication protocol "my authentication pass" AES "my 
privacy pass"
For this statement, define the listed parameters, which include the following:

–ENGINEID—The EngineID of the application that is going to be sending the trap

–myuser—The USM username that is going to be sending the trap

–authentication protocol—The authentication type (SHA or MD5, with SHA the preferred setting.)

–"my authentication pass"—The authentication pass-phrase to use to generate the secret authentication key. Enclose the pass-phrase in quotation marks if it includes spaces.

–privacy protocol—The encryption type to use (AES or DES, with AES the preferred setting)

–"my privacy pass"—The encryption pass-phrase to use to generate the secret encryption key. Enclose the pass-phrase in quotation marks if it includes spaces. If you do not enclose the encryption pass-phrase in quotation marks, it is set to the same value as the authentication pass-phrase.

Step 2 In the /tmp/snmptrapd.conf file, enter the following statement:
createUser -e 80000009fe8949e0b20319e2d175b93fe7dc24af0dff7db915 md5des MD5 mysecretpass 
DES passphrase
Step 3 Run the snmptrapd command, pointing to that file.

Note This process runs in the foreground, uses only the specified configuration file, and logs messages to the stderr file.
[root@iLinux2 net-snmp]# snmptrapd -f -C -c /tmp/snmptrapd.conf -Le
Step 4 Run the snmptrap command from the adaptive security appliance to send a linkdown or linkup trap by entering the following commands:
hostname (config)# int g3/1.391
hostname (config-if)# shut
hostname (config-if)# no shut
The following is sample output from the snmptrap command:
2009-03-18 23:52:06 NET-SNMP version 5.1.2 Started.
2009-03-18 23:52:20 10.31.8.254 [10.31.8.254]:
SNMPv2-MIB::sysUpTime.0 = Timeticks: (938700) 2:36:27.00        SNMPv2-MIB::snmp
TrapOID.0 = OID: IF-MIB::linkDown       IF-MIB::ifIndex.1 = INTEGER: 1  IF-MIB::
ifAdminStatus.1 = INTEGER: down(2)      IF-MIB::ifOperStatus.1 = INTEGER: down(2
)
2009-03-18 23:52:22 10.31.8.254 [10.31.8.254]:
SNMPv2-MIB::sysUpTime.0 = Timeticks: (939000) 2:36:30.00        SNMPv2-MIB::snmp

The Messages dialog box appears (see Figure 2-42), which shows the packet contents of the SNMP communication between the MIB Browser and the SNMP agent. This information is helpful for debugging.

Figure 2-42 Packet Trace in the Messages Dialog Box

Using the NNM SNMP Version 3 Trap Viewer

When using the NNM SNMP Version 3 Trap Viewer, perform the following steps:

Step 1 Make sure that the SNMP Version 3 credentials of a user on the SNMP agent are cached in the NNM.

Step 2 When using the MIB Browser to query an SNMP agent, enter the following community string:
3P:authpass:privpass/KEEP/titandes 
Note By using the KEEP parameter in the overloaded community string, you save the user credentials in the NNM configuration file, which is required because secure SNMP Version 3 traps and inform requests are sent from the SNMP agent to the NNM, and authentication must occur. The user information is included in the configuration file, located in C:\etc\srconf\mgr\mgr.cnf. You can modify this file directly. For instructions, see the NNM SPI SNMP Version 7.53 documentation.

Alternatively, you can use the snmpget command, as shown in the following example:
C:\Program Files\HP OpenView\bin>snmpget -c "3P;MD5^authpass;DES^privpass/KEEP/titandes" 
10.0.0.33 sysDescr.0
Step 3 To configure the SNMP agent to send traps, enter the following command on the adaptive security appliance:
hostname (config)# snmp-server host inside 10.0.0.10 traps version 3 titandes
Note The command syntax may differ slightly between adaptive security appliance platforms. The user configured in this example is the same as the user defined in the community string in the "Configuring the NNM MIB Browser" section.

The NNM traprcv utility is a command-line tool that receives SNMP trap messages and responds to SNMP inform requests from remote SNMP entities. It binds to the SNMP trap port (udp/162) to listen for notifications, and as a result, must be run as root. It prints standard output messages about the notifications that it has received. The traprcv utility can receive SNMP Version 1 traps, SNMP Version 2c traps, SNMP Version 2c inform requests, SNMP Version 3 traps, and SNMP Version 3 inform requests. For more information, see the NNM SPI SNMP Version 7.53 documentation.

Step 4 Run the traprcv utility and wait for traps on the SNMP agent. The utility is available at the following location (see Figure 2-43): C:\Program Files\HP OpenView\snmpv3\utils\traprcv.exe.

The read-write username and password for SNMP Version 3 and the read-write community string for SNMP Versions 1 and 2c are case sensitive. The SNMP Walk dialog box displays the credentials (SNMP Versions 1, 2c, and 3) for the device from the Device and Credential Repository (DCR), if they are available. Otherwise, the default values for the respective SNMP versions appear.

If you use the SNMP Walk feature with Network Operator/Help Desk access privileges, device credential fetching fails and the fields of the read/write community strings for SNMP Versions 1, 2c, and 3 credentials are set to default values.

Figure 2-49 shows the list of privacy protocols supported. You must manually enter SNMP Versions 1, 2c, and 3 credentials (see Figure 2-52).

Using the Management Station to Device Tool

To troubleshoot problems with unmanaged or unresponsive devices, you can check the device connectivity by protocol. The Management Station to Device tool helps you diagnose Layer 4 (application) connectivity problems.

Layer 4 tests include the following key services essentials that are needed to manage network devices:

•Debugging and measurement tools (UDP and TCP)

•Web server (HTTP)

•File transfer (TFTP)

•Terminal (Telnet)

•Read-write access (SNMP)

The management station to device check occurs only for protocol connectivity. Credentials for the corresponding protocols are not tested or verified. If you enter a hostname instead of an IP address, the tool performs a name lookup to discover the address. This task fails if the tool cannot find an address.

You can use this tool to send an SNMP GET request to the destination device for an SNMP read test (SNMPR). The tool also sends an SNMP SET request to the device for an SNMP write test (SNMPW). This protocol is supported for SNMP Versions 1, 2c, and 3.

If you start the Management Station to Device tool with Network Operator/Help Desk access privileges, device credential fetching fails and the fields of the read-write community strings for SNMP Versions 1, 2c, and 3 credentials are set to default values. You must manually enter SNMP Versions 1, 2c, and 3 credentials.

To start the Management Station to Device tool, perform the following steps:

Step 1 Choose Device Diagnostic Tools > Device Center.

Step 2 Enter the name or IP address, fully qualified domain name, or hostname of the device that you want to check in the Device Selector field or select the device from the list, and click Go.

The Summary and Functions Available panes appear.

Step 3 Click Management Station to Device in the Functions Available pane.

The Management Station to Device dialog box appears (see Figure 2-54).

Figure 2-54 Management Station to Device Dialog Box

Step 4 Choose the connectivity applications that you want to include from the following options. All fields are case sensitive.

•If you choose SNMP v3 (NoAuthNoPriv Security Level), enter the following information:

–Read Username.

–Write Username.

–Timeout (in seconds). The default value is two seconds.

•If you choose SNMP v3 (AuthNoPriv Security Level), enter the following information:

–Read Username.

–Read Auth Password.

–Read Auth Protocol. Choose either MD5 or SHA from the drop-down list.

–Write Username.

–Write Auth Password.

–Write Auth Protocol. Choose MD5 or SHA from the drop-down list.

–Timeout (in seconds). The default value is two seconds.

•If you choose SNMP v3 (AuthPriv Security Level), enter the following information:

–Read Username.

–Read Auth Password.

–Read Auth Protocol. Choose MD5 or SHA from the drop-down list.

–Read Privacy Password.

–Read Privacy Protocol. Choose a privacy protocol from the drop-down list. The available protocols are DES, 3DES, AES128, AES192, and AES256.

–Write Username.

–Write Auth Password.

–Write Auth Protocol. Choose MD5 or SHA from the drop-down list.

–Write Privacy Password.

–Write Privacy Protocol. Choose a privacy protocol from the drop-down list. The available protocols are DES, 3DES, AES128, AES192, and AES256.

–Timeout (in seconds). The default value is two seconds.

The Interface Test Results dialog box displays the results (see Figure 2-55). The Interface Details Results dialog box shows the interfaces tested and the test results for each option.

Note The read-write username and password for SNMP Version 3 and the read-write community string for SNMP Versions 1 and 2c are case sensitive.

[root@iLinux2 ~]# snmpwalk -v3 -u md5des -l authPriv -a MD5 -A mysecretpass -x des -X passphrase 10.31.8.254 1.3.6.1.2.1.1 The following is sample output from the snmpwalk command: SNMPv2-MIB::sysDescr.0 = STRING: Cisco Adaptive Security Appliance Version 8.2(0)227 SNMPv2-MIB::sysObjectID.0 = OID: SNMPv2-SMI::enterprises.9.1.915 SNMPv2-MIB::sysUpTime.0 = Timeticks: (486600) 1:21:06.00 SNMPv2-MIB::sysContact.0 = STRING: admin admin SNMPv2-MIB::sysName.0 = STRING: ciscoasa SNMPv2-MIB::sysLocation.0 = STRING: sjc - 190 W Tasman Drive, San Jose, CA 95134 USA SNMPv2-MIB::sysServices.0 = INTEGER: 4 Sending a Trap When the adaptive security appliance sends a trap, it is authoritative, which means that the user created within the snmptrapd command must be associated with the EngineID sending the trap. To establish this association, perform the following steps: Step 1 In the /var/net-snmp/snmptrapd.conf file, enter the following statement: createUser -e ENGINEID myuser authentication protocol "my authentication pass" AES "my privacy pass" For this statement, define the listed parameters, which include the following: –ENGINEID—The EngineID of the application that is going to be sending the trap –myuser—The USM username that is going to be sending the trap –authentication protocol—The authentication type (SHA or MD5, with SHA the preferred setting.) –"my authentication pass"—The authentication pass-phrase to use to generate the secret authentication key. Enclose the pass-phrase in quotation marks if it includes spaces. –privacy protocol—The encryption type to use (AES or DES, with AES the preferred setting) –"my privacy pass"—The encryption pass-phrase to use to generate the secret encryption key. Enclose the pass-phrase in quotation marks if it includes spaces. If you do not enclose the encryption pass-phrase in quotation marks, it is set to the same value as the authentication pass-phrase. Step 2 In the /tmp/snmptrapd.conf file, enter the following statement: createUser -e 80000009fe8949e0b20319e2d175b93fe7dc24af0dff7db915 md5des MD5 mysecretpass DES passphrase Step 3 Run the snmptrapd command, pointing to that file. Note This process runs in the foreground, uses only the specified configuration file, and logs messages to the stderr file.

Browsing a MIB To browse a MIB, perform the following steps: Step 1 Drill down to the OID, .iso.org.dod.internet.mgmt.mib-2.system, and select the system object. Step 2 Click Start Query to fill in the MIB Values field with the DUT description (see Figure 2-41). Figure 2-41 Browse MIB Dialog Box Running a MIB Browser Packet Trace To run a MIB Browser packet trace, in the MIB Browser dialog box, choose View > SNMP Packet Trace. The Messages dialog box appears (see Figure 2-42), which shows the packet contents of the SNMP communication between the MIB Browser and the SNMP agent. This information is helpful for debugging. Figure 2-42 Packet Trace in the Messages Dialog Box Using the NNM SNMP Version 3 Trap Viewer When using the NNM SNMP Version 3 Trap Viewer, perform the following steps: Step 1 Make sure that the SNMP Version 3 credentials of a user on the SNMP agent are cached in the NNM. Step 2 When using the MIB Browser to query an SNMP agent, enter the following community string: 3P:authpass:privpass/KEEP/titandes Note By using the KEEP parameter in the overloaded community string, you save the user credentials in the NNM configuration file, which is required because secure SNMP Version 3 traps and inform requests are sent from the SNMP agent to the NNM, and authentication must occur. The user information is included in the configuration file, located in C:\etc\srconf\mgr\mgr.cnf. You can modify this file directly. For instructions, see the NNM SPI SNMP Version 7.53 documentation. Alternatively, you can use the snmpget command, as shown in the following example: C:\Program Files\HP OpenView\bin>snmpget -c "3P;MD5^authpass;DES^privpass/KEEP/titandes" 10.0.0.33 sysDescr.0 Step 3 To configure the SNMP agent to send traps, enter the following command on the adaptive security appliance: hostname (config)# snmp-server host inside 10.0.0.10 traps version 3 titandes Note The command syntax may differ slightly between adaptive security appliance platforms. The user configured in this example is the same as the user defined in the community string in the "Configuring the NNM MIB Browser" section. The NNM traprcv utility is a command-line tool that receives SNMP trap messages and responds to SNMP inform requests from remote SNMP entities. It binds to the SNMP trap port (udp/162) to listen for notifications, and as a result, must be run as root. It prints standard output messages about the notifications that it has received. The traprcv utility can receive SNMP Version 1 traps, SNMP Version 2c traps, SNMP Version 2c inform requests, SNMP Version 3 traps, and SNMP Version 3 inform requests. For more information, see the NNM SPI SNMP Version 7.53 documentation. Step 4 Run the traprcv utility and wait for traps on the SNMP agent. The utility is available at the following location (see Figure 2-43): C:\Program Files\HP OpenView\snmpv3\utils\traprcv.exe. Figure 2-43 SNMP Trap Receiver Using the HP OpenView NNM Web Application To start the NNM web application, perform the following steps: Step 1 In a web browser, go to the following URL: http://<NNM-Server-IP-Address>:7510/topology/home Step 2 To view SNMP nodes, from the drop-down menu, choose Internet View (see Figure 2-44).

Figure 2-46 shows the login page. Figure 2-46 Login Page Getting Started with the CiscoWorks LMS Portal The CiscoWorks LMS Portal is the first page (see Figure 2-47) that appears when you start the LMS application. This page serves as the interface, starting point, and top-level navigation for the frequently used functions in the application. Figure 2-47 CiscoWorks LMS Portal Page Using the Device Center To manage devices, perform the following steps: Step 1 Choose Device Diagnostic Tools > Device Center (see Figure 2-48). The Device Center Home page appears with the Device Selector in the left pane and Device Center summary information in the right pane. Step 2 Enter the IP address or device name or choose a device from the list in the Device Selector pane, and click Go. Figure 2-48 Device Center Home Window Performing an SNMP Walk To perform an SNMP walk, perform the following steps: Step 1 In the Functions Available pane, click the SNMP Walk link. The SNMP Walk dialog box appears (see Figure 2-49). Figure 2-49 SNMP Walk Dialog Box Step 2 Choose the SNMP version to use from the following options: •For SNMP Version 3 (NoAuthNoPriv and AuthNoPriv Security Levels) a. Enter the SNMPv3 Username. b. Enter the SNMPv3 Auth Password. c. Choose the SNMP v3 Auth Protocol from the drop-down list (either MD5 or SHA). d. Enter the SNMP Context Name. Note Because the adaptive security appliance does not support contexts, you must leave the SNMP Context Name blank. •For SNMP Version 3 (AuthPriv Security Level) a. Enter the SNMPv3 Username. b. Enter the SNMPv3 Auth Password. c. Specify the SNMP v3 Auth Protocol. Choose either MD5 or SHA. d. Enter the Privacy Password. e. Choose a privacy protocol from the drop-down list. The available values are DES, 3DES, AES128, AES192, and AES256. f. Enter the SNMP Context Name. Note Because the adaptive security appliance does not support contexts, you must leave the SNMP Context Name blank. g. (Optional) Enter the starting OID. If you leave this field blank, the tool starts from 1. h. Enter the SNMP Timeout. The default value is 10 seconds. i. (Optional) Check the Output OIDs Numerically check box to print the output OIDs numerically. j. By default, the corresponding OID name is printed in the output window. k. (Optional) Check the Output Indexes Numerically check box to show the output index numerically. l. (Optional) Check the Debug check box to enable the debugging option. All the fields are case-sensitive. m. Click OK to obtain the results, which are based on the parameters that you entered. n. When the walk is complete, save it as a text file (see Figure 2-50). Note A full walk may take a long time to finish. Figure 2-50 SNMP Walk Results Example The read-write username and password for SNMP Version 3 and the read-write community string for SNMP Versions 1 and 2c are case sensitive. The SNMP Walk dialog box displays the credentials (SNMP Versions 1, 2c, and 3) for the device from the Device and Credential Repository (DCR), if they are available. Otherwise, the default values for the respective SNMP versions appear. If you use the SNMP Walk feature with Network Operator/Help Desk access privileges, device credential fetching fails and the fields of the read/write community strings for SNMP Versions 1, 2c, and 3 credentials are set to default values. Figure 2-49 shows the list of privacy protocols supported. You must manually enter SNMP Versions 1, 2c, and 3 credentials (see Figure 2-52). Figure 2-51 SNMP Walk Dialog Box Figure 2-52 SNMP Version 3 Parameters Figure 2-53 shows the SNMP walk results for the MD5 authentication and AES256 encryption algorithm settings. Figure 2-53 SNMP Walk Results Dialog Box Using the Management Station to Device Tool To troubleshoot problems with unmanaged or unresponsive devices, you can check the device connectivity by protocol. The Management Station to Device tool helps you diagnose Layer 4 (application) connectivity problems. Layer 4 tests include the following key services essentials that are needed to manage network devices: •Debugging and measurement tools (UDP and TCP) •Web server (HTTP) •File transfer (TFTP) •Terminal (Telnet) •Read-write access (SNMP) The management station to device check occurs only for protocol connectivity. Credentials for the corresponding protocols are not tested or verified. If you enter a hostname instead of an IP address, the tool performs a name lookup to discover the address. This task fails if the tool cannot find an address. You can use this tool to send an SNMP GET request to the destination device for an SNMP read test (SNMPR). The tool also sends an SNMP SET request to the device for an SNMP write test (SNMPW). This protocol is supported for SNMP Versions 1, 2c, and 3. If you start the Management Station to Device tool with Network Operator/Help Desk access privileges, device credential fetching fails and the fields of the read-write community strings for SNMP Versions 1, 2c, and 3 credentials are set to default values. You must manually enter SNMP Versions 1, 2c, and 3 credentials. To start the Management Station to Device tool, perform the following steps: Step 1 Choose Device Diagnostic Tools > Device Center. Step 2 Enter the name or IP address, fully qualified domain name, or hostname of the device that you want to check in the Device Selector field or select the device from the list, and click Go. The Summary and Functions Available panes appear. Step 3 Click Management Station to Device in the Functions Available pane. The Management Station to Device dialog box appears (see Figure 2-54). Figure 2-54 Management Station to Device Dialog Box Step 4 Choose the connectivity applications that you want to include from the following options. All fields are case sensitive. •If you choose SNMP v3 (NoAuthNoPriv Security Level), enter the following information: –Read Username. –Write Username. –Timeout (in seconds). The default value is two seconds. •If you choose SNMP v3 (AuthNoPriv Security Level), enter the following information: –Read Username. –Read Auth Password. –Read Auth Protocol. Choose either MD5 or SHA from the drop-down list. –Write Username. –Write Auth Password. –Write Auth Protocol. Choose MD5 or SHA from the drop-down list. –Timeout (in seconds). The default value is two seconds. •If you choose SNMP v3 (AuthPriv Security Level), enter the following information: –Read Username. –Read Auth Password. –Read Auth Protocol. Choose MD5 or SHA from the drop-down list. –Read Privacy Password. –Read Privacy Protocol. Choose a privacy protocol from the drop-down list. The available protocols are DES, 3DES, AES128, AES192, and AES256. –Write Username. –Write Auth Password. –Write Auth Protocol. Choose MD5 or SHA from the drop-down list. –Write Privacy Password. –Write Privacy Protocol. Choose a privacy protocol from the drop-down list. The available protocols are DES, 3DES, AES128, AES192, and AES256. –Timeout (in seconds). The default value is two seconds. The Interface Test Results dialog box displays the results (see Figure 2-55). The Interface Details Results dialog box shows the interfaces tested and the test results for each option. Note The read-write username and password for SNMP Version 3 and the read-write community string for SNMP Versions 1 and 2c are case sensitive.
