I want to retrieve serial numbers from multiple devices using SNMP. I'm just using the net-snmp.org snmpget/snmpwalk tools

I am finding that the SNMP OID for serial numbers is different on different hardware, even with cisco, for example:

Cisco Aironet    1.3.6.1.4.1.9.9.92.1.1.1.2.1
Cisco 2950       1.3.6.1.4.1.9.3.6.3
Xerox printer    1.3.6.1.2.1.43.5.1.1.17.1

I dont really understand MIBS, but is there any way of constructing a MIB file or getting existing MIB files to extract serial numbers that would cover all SNMP products? Any comments and discussion which helps me understand how snmp works in this regard would also be appreciated

thanks

MIB's - it is manufactureie devoped file, support certain functionality.
You need to check with manufacturies , if they do have MIB's  allowing to pull serial#.

snmpwalk - basicly will show you available MIB's on particular hardware- therefore given you idea, what kind of info/statistics, you get retrive from device.
1.By telnet
Router# show inventory
2.snmpget -v1 -c communitystring hostorIP mib-2.47.1.1.1.1.11.1The output looks like this:

SNMPv2-SMI::mib-2.47.1.1.1.1.11.1 = STRING: "FDC01235PAN"If you want to write a batch file to automate the process, follow these steps:

Download Gawk for Windows (awk) to parse the output from the snmpget command.
Install both tools in the same directory.
Create a text file that lists the router hostnames or IP addresses; name it Routers.txt.
Put the following in a batch file (I called mine Getsnscript.tx) and run it:
@echo off
for /F %%1 in ('type routers.txt') do snmpget -v1 -c
cisco %%1 mib-2.47.1.1.1.1.11.1 | awk -F" " "{ print $4 }"The output might look something like this:

C:netsnmpbin> getsnscript.bat
"FO234C35PXN"    

"FTX093431P13    

"FO234C35PXN"If you want, you can redirect it to a text file and import that text file to a spreadsheet. Of course, you can also get much more complex with the script and retrieve more information.

3.Use SNMP from a GUI application
Of course, there are always GUI applications that can accomplish the same thing as CLI scripts. I've found that Kiwi CatTools- http://www.kiwisyslog.com/kiwi-cattools-overview/  (freeware for up to five devices) does a fine job of retrieving the serial number of routers and provides a nice inventory.


If your routers are newer and the results of the show inventory command are accurate, you should be able to easily retrieve your router's proper chassis serial number remotely over the network. However, with older models, you may have to first manually enter the router serial number into the IOS to be able to remotely retrieve it.

For Cisco in particular:

http://www.cisco.com/warp/public/477/SNMP/chassis.shtml
http://www.cisco.com/en/US/docs/ios/12_3t/12_3t4/feature/guide/gtpepudi.html

Other hardware needs to be confirm , if they can do so.
