Telnet to your switch and issue the command 'show version'
This is what I get on my switch:
DRAM FLASH NVRAM
Module Total Used Free Total Used Free Total Used Free
------ ------- ------- ------- ------- ------- ------- ----- ----- -----
1 65408K 42834K 22574K 16384K 9896K 6488K 512K 274K 238K
(The memory part of show version, anyway)
Here's that section on my MRTG log for that switch using my OID's:

(snip)
You can see that the first oid is for memory used and the second one is
memory free.
Take a look at the MRTG page for that switch:
http://redhook.univ-wea.com/mrtg/cisco.farm1.memory.html
Maybe I'm wrong 'cause I found the oid's on my own, but they look pretty
close ;)
Hope it helps.
If any cisco gurus wanna help us out here I would sure appreciate it...

What to you get when you do an snmpget on 1.3.6.1.4.1.9.2.1.8.0?
I'm graphing memory used and memory free on a 6509 and the oid's that I'm
using are:
Memory used: 1.3.6.1.4.1.9.9.48.1.1.1.6.1
Memory free: 1.3.6.1.4.1.9.9.48.1.1.1.5.1

Subject: [mrtg] Cisco free memory
Hello everyone. I am trying to graph free memory on a Cisco 3500 switch. I
looked up the IOD for it and configured the mrtg config file as follows:
#### Free Memory ######
Target[Cisco.mem]:
1.3.6.1.4.1.9.2.1.8.0&1.3.6.1.4.1.9.2.1.8.0:public at 172.16.1.2
MaxBytes[Cisco.mem]: 3421612
Options[Cisco.mem]: growright, nopercent, gauge
XSize[Cisco.mem]: 380
YSize[Cisco.mem]: 100
YLegend[Cisco.mem]: RAM Free (KB)
ShortLegend[Cisco.mem]: Bytes
LegendI[Cisco.mem]: KB
LegendO[Cisco.mem]:
Title[Cisco.mem]: Free memory
PageTop[Cisco.mem]: <H1> Catalyst 3500XL - Free memory</H1>
However, the graph is showing me there is 0MB free all the time, I don't
believe that is correct. I looked at the .log file and all the values it's
getting back from the switch are Zeros. Any ideas? IS the OID correct?
Thanks,
Yanal
