some missing oids

[kulinski]

hi,

at the moment i'm creating an excel sheet with listing of interface parameters and oids for a later planned snmp request.

problem is that there are still some empty fields at the column oid :-)

these are:

duplex

last clearing

total output drops

rec broadcasts

throttles

total input errors

deferred

maybe someone has one or two of these oid.

kind regards

Try an extended search in the SNMP object browser http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en

hey kevin,

i still know that link and i'd been working with the mib browser to find out all the other oids i already have in the table.

but you see, i havn't found all i need...

kind regards

I could find some IODs for specific Catalysts, but a global MIB might be more difficult. Here are some to consider. (Couldn't find broadcasts, but could find broadcasts and multicasts lumped together.)

dot3StatsDeferredTransmissions = 1.3.6.1.2.1.10.7.2.1.7 (ETHERLIKE-MIB)

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.2.2.1.12

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.2.2.1.18

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.2.2.1.19 (Not sure of the difference between discards and drops)

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.2.2.1.1.26

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.2.2.1.1.27

Of course, I cannot guarantee that your switch supports any particular OID.

Good luck in your search.

Chris,

How were those OIDs I posted; were they useful? Which ones are you still missing now?

hi kevin,

first, thanks for your help.

nearly all the oids you posted were usefull.

but i'm still looking for some... :)

duplex

last clearing

total output drops ( should be sum of all error counters for output )

input drops

throttles

kind regards

What routers/switches are you interested in? If they are Cat2900 series, you can get the duplex state on:

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.87.1.4.1.1.31

For a 2600 router, duplex can be read on:

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.1.111.1.2.2.1.1.21

This is a generic duplex OID:

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.10.7.2.1.19

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.2.1.35.2.1.7

I thought "drops" were the same as discards, which is not the same thing as errors. Drops is were you deliberately drop the packet 'cos the queue is full or something like that.

In terms of error counters, I suspect you will have to read them individually, then add them all up. If I see any composite error counters, I'll let you know.

Throttles may be related to:

Last clearing is at this OID, but it is deprecated:

BTW, there is some guidance about all this in the CCIE design and case studies book:

http://www.amazon.com/exec/obidos/tg/detail/-/1578701678/qid=1095069936/sr=1-1/ref=sr_1_1/103-9398348-6244636?v=glance&s=books

It's out of print, but it's well worth while looking for a copy, or perhaps seeing if it is on InformIt Safari. Look at chapter 14 in particular.

hi kevin,

again thanks for your time.

i'll work through your postings in the following.

think the ccie book will be hard stuff for me ( i'm just going to certificate as a ccna next week...)

nevertheless i'll maybe have a look for it .

kind regards

Chris,

I've got some more useful documentations about SNMP management, but it is too big to post here. Send me an e-mail, and I'll send you the document in reply.

I hide my e-mail to try and avoid Spam, but it sounds like: Kevin dot Dorrell at pt dot lu

Chris,

I found you another possible reference for lastClearingTime. Unfortunately it is an offset from the system uptime, but here it is:

hi kevin,

you did want to send me some files about snmp, didn't you ?

sounds like chris dot kulinski at dresdner minus bank dot com...

maybe i didn't get the point on yours but i did send you a mail...

kind regards

If you are a Windows user, get a copy of GETIF (search and you'll find a download site). This tool allows browsing of MIBs and displays the OID in a box. You can also get the variable which is handy to see if you have the right variable, or if the box supports that MIB etc. It's a very handy tool for the work you are doing.

thanks,

i'm sure that tool will help.
