Task 2— Exploring SNMP Capabilities by Using UCD-SNMP

About Using UCD-SNMP

Researching and identifying which functions are available in SNMP are part of building a dial NMS environment. In this case study, UCD-SNMP, an opensource freeware application that allows access to SNMP functions from a command line interface (CLI), is used to explore the capabilities of SNMP.

There are many benefits to using UCD-SNMP.

You can:

•Gain a fundamental understanding of how SNMP functions and protocols work in a dial access environment. This knowledge provides a solid foundation for using automated and GUI-based SNMP applications.

•Learn how to use a low-level troubleshooting capability in the event that other SNMP applications produce questionable results.

•Poll any OID and verify SNMP agent responses.

•Use stable and reliable CLI commands. UCD-SNMP is unobstructed by GUI functionality.

•Explore and research MIB content.

•Discover what functions are available to manage a Cisco IOS device.

•Create customized scripts and tools.

For this case study, the dial engineers at THEnet created a tool called SNMP Commander. The tool aided the MIB research task by enabling dial engineers to build web-based object identification (OIDs) bookmarks, which they could go to without using a keyboard.

By using UCD-SNMP and SNMP Commander, the dial engineers at THEnet identified which items the commercial NMS applications would monitor within the network operations center (NOC).

Installing UCD-SNMP and Downloading Cisco MIBs

To install UCD-SNMP and download MIBs from the Cisco FTP site, follow these steps.

Note You can also download individual MIBs from http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml

Step 1 Go to http://net-snmp.sourceforge.net/

Step 2 Download, compile, and install UCD-SNMP. In this case study, the UCD-SNMP commands are installed in the /usr/local/bin directory.

Step 3 From the Cisco FTP site, download the MIBs into the /usr/local/share/snmp/mibs directory on your Solaris workstation. By using the following Unix commands, you can copy the entire bundled v1 MIB tar file from ftp.cisco.com.

cd /usr/local/share/snmp/mibs

ftp ftp.cisco.com

cd /pub/mibs/v1

bin

get v1.tar.gz

exit

Step 4 Decompress and untar the files in the /usr/local/share/snmp/mibs directory:

gzip -d v1.tar.gz

tar -xvf v1.tar

Note There are many MIBs in the tar file that you may not use. Regardless, Cisco recommends you keep all the MIBs on file to support your evolving network needs.

Exploring SNMP MIBs for Dial Networks

To explore the MIBs for a Cisco IOS device by using SNMP CLI commands, follow the steps in this section. Poll OID variables by using the commands snmpget, snmpwalk, and snmptable.

Note This section assumes you already have a basic understanding of UCD-SNMP and know how to use its CLI commands.

Step 1 To determine the last restart reason for the router, enter the snmpget command and the relevant OID. In the following example, the restart reason is "reload."

onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0

Counter32 (is a reserved word): At line 6 in /usr/local/share/snmp/mibs/SNMPv2-S 
MI-V1SMI.my

Gauge32 (is a reserved word): At line 7 in /usr/local/share/snmp/mibs/SNMPv2-SMI

-V1SMI.my

Integer32 (is a reserved word): At line 8 in /usr/local/share/snmp/mibs/SNMPv2-S

MI-V1SMI.my

Did not find 'mib-2' in module RFC1213-MIB (/usr/local/share/snmp/mibs/IANAifTyp

e-MIB-V1SMI.my)

enterprises.9.2.1.2.0 = "reload"

If SNMP-parsing errors are generated, suppress them by appending 2>/dev/null to the end of the command. Standard output is tagged as 1. Error output is tagged as 2.

onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0 2> /dev/null

enterprises.9.2.1.2.0 = "reload"

onionring:~$

Note If no response is returned by the SNMP agent, allow error messages to print to the screen by removing the 2>/dev/null argument.

Step 2 Check the system up time by entering the snmpget command and sysUpTime OID:

onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.2.1.system.sysUpTime.0 2> 
/dev/null

system.sysUpTime.0 = Timeticks: (45450609) 5 days, 6:15:06.09

onionring:~$

Step 3 To gather basic configuration management information about the Cisco IOS device, enter the snmpwalk command and the system OID.

onionring:~$ snmpwalk travis-nas-01.the.net 5urf5h0p system 2> /dev/null

system.sysDescr.0 = "Cisco Internetwork Operating System Software ..IOS (tm) 5800 
Software (C5800-P4-M), Version 12.1(2a)T1,  RELEASE SOFTWARE (fc2)..Copyright

(c) 1986-2000 by cisco Systems, Inc...Compiled Mon 12-Jun-00 23:13 by ccai"

system.sysObjectID.0 = OID: enterprises.9.1.188

system.sysUpTime.0 = Timeticks: (45492606) 5 days, 6:22:06.06

system.sysContact.0 = "net-admin@aurora.the.net"

system.sysName.0 = "travis-nas-01.the.net"

system.sysLocation.0 = "Lake Travis (Austin) Dial POP"

system.sysServices.0 = 78

system.8.0 = Timeticks: (0) 0:00:00.00

onionring:~$

Step 4 Change the OID environmental prefix by entering the commands prefix and export prefix. This step reduces the number of key strokes you must enter at the command line.

onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0 2> /

dev/null

enterprises.9.2.1.2.0 = "reload"

onionring:~$ PREFIX=.1.3.6.1.4.1.9

onionring:~$ export PREFIX

onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p 2.1.2.0 2> /dev/null

enterprises.9.2.1.2.0 = "reload"

onionring:~$

The UCD-SNMP application attaches a prefix to the requested variable unless it is fully qualified (for example, unless the variable starts with a period "."). By default, the prefix points to the MIB-II node .1.3.6.1.2.1 location. The Cisco enterprises prefix points to .1.3.6.1.4.1.9

Step 5 Inspect the IP address entry table by entering the snmptable command and ipAddrTable OID:

onionring:~$ snmptable travis-nas-01.the.net 5urf5h0p ip.ipAddrTable 2> /dev/null

SNMP table: ip.ipAddrTable.ipAddrEntry

ipAdEntAddr ipAdEntIfIndex  ipAdEntNetMask ipAdEntBcastAddr ipAdEntReasmMaxSize

172.21.10.1            351   255.255.255.255              1              18024

172.21.101.20          289   255.255.255.0                1              18024

onionring:~$

Step 6 Poll the interfaces table and redirect the output to a text file by entering the snmptable command and ifTable OID:

onionring:~$ snmptable travis-nas-01.the.net 5urf5h0p interfaces.ifTable  
> /export/home/www/travis-nas-01_ifTable.txt

onionring:~$

Note Do not forget the space between > and /export

Step 7 Inspect the contents of the interfaces table by entering the cat command. In the following Cisco AS5800 example, notice the interface descriptions (ifDescr) and types (ifType). There is one PPP and DS0 entry for each serial interface.

onionring:~$ cat /export/home/www/travis-nas-01_ifTable.txt

SNMP table: interfaces.ifTable.ifEntry

 ifIndex                         ifDescr                 ifType ifMtu    ifSpeed ........

About SNMP Commander

The dial engineers at THEnet created a tool called SNMP Commander that:

•Provides web-based access to UCD-SNMP CLI commands.

•Builds web-based OID bookmarks, which enable you to go to OIDs without using a keyboard.

•Aids the MIB exploration and NMS design tasks.

By using SNMP Commander and a web browser, you can:

•Create URL links for the network staff and help desk.

•Identify target OIDs you want to graph by using MRTG.

•Inspect thresholds and events to monitor by using other NMS systems.

The following two components work together to create SNMP Commander:

•snmpcmds.dat—A comma separated variables file, which includes a list of SNMP CLI commands. This file is read by the snmpcmds.pl script.

The following is the source code for this file:

Setting Up SNMP Commander

To set up SNMP Commander, follow these steps:

Step 1 From CCO, download snmpcmds.dat and snmpcmds.pl

Step 2 Customize the files for your environment. When you find useful OIDs, enter them in the snmpcmds.dat file and use the web-based form of the script to research the MIBs. The web tool functions like an SNMP OID bookmarker.

Step 3 Test SNMP Commander by using a web browser:

a. Select an SNMP command and OID.

b. Select an SNMP agent (Cisco IOS device).

c. Click Submit.

d. Inspect the program and query messages.

In this case study, UCD-SNMP, an opensource freeware application that allows access to SNMP functions from a command line interface (CLI), is used to explore the capabilities of SNMP. There are many benefits to using UCD-SNMP. You can: •Gain a fundamental understanding of how SNMP functions and protocols work in a dial access environment. This knowledge provides a solid foundation for using automated and GUI-based SNMP applications. •Learn how to use a low-level troubleshooting capability in the event that other SNMP applications produce questionable results. •Poll any OID and verify SNMP agent responses. •Use stable and reliable CLI commands. UCD-SNMP is unobstructed by GUI functionality. •Explore and research MIB content. •Discover what functions are available to manage a Cisco IOS device. •Create customized scripts and tools. For this case study, the dial engineers at THEnet created a tool called SNMP Commander. The tool aided the MIB research task by enabling dial engineers to build web-based object identification (OIDs) bookmarks, which they could go to without using a keyboard. By using UCD-SNMP and SNMP Commander, the dial engineers at THEnet identified which items the commercial NMS applications would monitor within the network operations center (NOC). Installing UCD-SNMP and Downloading Cisco MIBs To install UCD-SNMP and download MIBs from the Cisco FTP site, follow these steps. Note You can also download individual MIBs from http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml Step 1 Go to http://net-snmp.sourceforge.net/ Step 2 Download, compile, and install UCD-SNMP. In this case study, the UCD-SNMP commands are installed in the /usr/local/bin directory. Step 3 From the Cisco FTP site, download the MIBs into the /usr/local/share/snmp/mibs directory on your Solaris workstation. By using the following Unix commands, you can copy the entire bundled v1 MIB tar file from ftp.cisco.com. cd /usr/local/share/snmp/mibs ftp ftp.cisco.com cd /pub/mibs/v1 bin get v1.tar.gz exit Step 4 Decompress and untar the files in the /usr/local/share/snmp/mibs directory: gzip -d v1.tar.gz tar -xvf v1.tar Note There are many MIBs in the tar file that you may not use. Regardless, Cisco recommends you keep all the MIBs on file to support your evolving network needs. Exploring SNMP MIBs for Dial Networks To explore the MIBs for a Cisco IOS device by using SNMP CLI commands, follow the steps in this section. Poll OID variables by using the commands snmpget, snmpwalk, and snmptable. Note This section assumes you already have a basic understanding of UCD-SNMP and know how to use its CLI commands. Step 1 To determine the last restart reason for the router, enter the snmpget command and the relevant OID. In the following example, the restart reason is "reload." onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0 Counter32 (is a reserved word): At line 6 in /usr/local/share/snmp/mibs/SNMPv2-S MI-V1SMI.my Gauge32 (is a reserved word): At line 7 in /usr/local/share/snmp/mibs/SNMPv2-SMI -V1SMI.my Integer32 (is a reserved word): At line 8 in /usr/local/share/snmp/mibs/SNMPv2-S MI-V1SMI.my Did not find 'mib-2' in module RFC1213-MIB (/usr/local/share/snmp/mibs/IANAifTyp e-MIB-V1SMI.my) enterprises.9.2.1.2.0 = "reload" If SNMP-parsing errors are generated, suppress them by appending 2>/dev/null to the end of the command. Standard output is tagged as 1. Error output is tagged as 2. onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0 2> /dev/null enterprises.9.2.1.2.0 = "reload" onionring:~$ Note If no response is returned by the SNMP agent, allow error messages to print to the screen by removing the 2>/dev/null argument. Step 2 Check the system up time by entering the snmpget command and sysUpTime OID: onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.2.1.system.sysUpTime.0 2> /dev/null system.sysUpTime.0 = Timeticks: (45450609) 5 days, 6:15:06.09 onionring:~$ Step 3 To gather basic configuration management information about the Cisco IOS device, enter the snmpwalk command and the system OID. onionring:~$ snmpwalk travis-nas-01.the.net 5urf5h0p system 2> /dev/null system.sysDescr.0 = "Cisco Internetwork Operating System Software ..IOS (tm) 5800 Software (C5800-P4-M), Version 12.1(2a)T1, RELEASE SOFTWARE (fc2)..Copyright (c) 1986-2000 by cisco Systems, Inc...Compiled Mon 12-Jun-00 23:13 by ccai" system.sysObjectID.0 = OID: enterprises.9.1.188 system.sysUpTime.0 = Timeticks: (45492606) 5 days, 6:22:06.06 system.sysContact.0 = "net-admin@aurora.the.net" system.sysName.0 = "travis-nas-01.the.net" system.sysLocation.0 = "Lake Travis (Austin) Dial POP" system.sysServices.0 = 78 system.8.0 = Timeticks: (0) 0:00:00.00 onionring:~$ Step 4 Change the OID environmental prefix by entering the commands prefix and export prefix. This step reduces the number of key strokes you must enter at the command line. onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p .1.3.6.1.4.1.9.2.1.2.0 2> / dev/null enterprises.9.2.1.2.0 = "reload" onionring:~$ PREFIX=.1.3.6.1.4.1.9 onionring:~$ export PREFIX onionring:~$ snmpget travis-nas-01.the.net 5urf5h0p 2.1.2.0 2> /dev/null enterprises.9.2.1.2.0 = "reload" onionring:~$ The UCD-SNMP application attaches a prefix to the requested variable unless it is fully qualified (for example, unless the variable starts with a period "."). By default, the prefix points to the MIB-II node .1.3.6.1.2.1 location. The Cisco enterprises prefix points to .1.3.6.1.4.1.9 Step 5 Inspect the IP address entry table by entering the snmptable command and ipAddrTable OID: onionring:~$ snmptable travis-nas-01.the.net 5urf5h0p ip.ipAddrTable 2> /dev/null SNMP table: ip.ipAddrTable.ipAddrEntry ipAdEntAddr ipAdEntIfIndex ipAdEntNetMask ipAdEntBcastAddr ipAdEntReasmMaxSize 172.21.10.1 351 255.255.255.255 1 18024 172.21.101.20 289 255.255.255.0 1 18024 onionring:~$ Step 6 Poll the interfaces table and redirect the output to a text file by entering the snmptable command and ifTable OID: onionring:~$ snmptable travis-nas-01.the.net 5urf5h0p interfaces.ifTable > /export/home/www/travis-nas-01_ifTable.txt onionring:~$ Note Do not forget the space between > and /export Step 7 Inspect the contents of the interfaces table by entering the cat command. In the following Cisco AS5800 example, notice the interface descriptions (ifDescr) and types (ifType). There is one PPP and DS0 entry for each serial interface. onionring:~$ cat /export/home/www/travis-nas-01_ifTable.txt SNMP table: interfaces.ifTable.ifEntry ifIndex ifDescr ifType ifMtu ifSpeed ........ 1 "Async1/2/00" other 1500 9000 2 "Async1/2/01" other 1500 9000 3 "Async1/2/02" other 1500 9000 . . . . 289 "FastEthernet0/0/0" ethernetCsmacd 1500 100000000 290 "Null0" other 1500 4294967295 291 "T1 1/0/0" ds1 ? ? 292 "T1 1/0/1" ds1 ? ? . . . . 301 "T1 1/0/10" ds1 ? ? 302 "T1 1/0/11" ds1 ? ? 303 "Serial1/0/0:0" propPointToPointSerial 1500 64000 304 "Serial1/0/0:1" propPointToPointSerial 1500 64000 . . . . 326 "Serial1/0/0:23" lapd 1500 64000 327 "Serial1/0/0:23-Signaling" isdn 1500 64000 328 "Serial1/0/0:0-Bearer Channel" ds0 ? ? 329 "Serial1/0/0:1-Bearer Channel" ds0 ? ? . . . . 350 "Serial1/0/0:22-Bearer Channel" ds0 ? ? 351 "Loopback0" softwareLoopback 15144294967295 About SNMP Commander The dial engineers at THEnet created a tool called SNMP Commander that: •Provides web-based access to UCD-SNMP CLI commands. •Builds web-based OID bookmarks, which enable you to go to OIDs without using a keyboard. •Aids the MIB exploration and NMS design tasks. By using SNMP Commander and a web browser, you can: •Create URL links for the network staff and help desk. •Identify target OIDs you want to graph by using MRTG. •Inspect thresholds and events to monitor by using other NMS systems. The following two components work together to create SNMP Commander: •snmpcmds.dat—A comma separated variables file, which includes a list of SNMP CLI commands.

When you find useful OIDs, enter them in the snmpcmds.dat file and use the web-based form of the script to research the MIBs. The web tool functions like an SNMP OID bookmarker. Step 3 Test SNMP Commander by using a web browser: a. Select an SNMP command and OID. b. Select an SNMP agent (Cisco IOS device). c. Click Submit. d. Inspect the program and query messages.
