about getting ports of a switch

[moonquelle]

Hi all,

I'm tring to write a little program in Ruby which connects to a switch, then take the mac addresses and ports of the devices; which were related to the switch.

So, i walk on this mib to get mac addresses; "1.3.6.1.2.1.17.4.3.1.1"

Then i get many variables like this:

"1.3.6.1.2.1.17.4.3.1.1.0.0.12.7.172.8"

Then i convert the last 6 numbers to hex (i took
"0.0.12.7.172.8" then i convert them to hex one by one, and i get the mac address like "00 00 0C 07 AC 08").

It's ok. But i stucked up about ports.


I used this mib "1.3.6.1.2.1.17.4.3.1.2" to get the ports. I get something like this:

"1.3.6.1.2.1.17.4.3.1.2.0.0.33.207.215.190"

So, as i did in mac addresses, i wanted to convert this
("1.3.6.1.2.1.17.4.3.1.2.0.0.33.207.215.190") to a port number.


But i couldn't find, how i will do that?

I searched a lot, but couldn't find a usefull answer. If you have any idea about converting these to port numbers? Or where am i wrong?

Take a look at the (unknown) script from our MRTG friend Tobias, named cammer.
This perl script queries your switch and your router and provides a list of Ports with corresponding MAC addresses and corresponding IP addresses which are in use on your switch.
Perhaps you can use this at your advantage.
