Now the problem is the cisco 7500 we have for DSL.
checkrad (running full debug mode on radius) shows
no response


The world is not perfect. :-)))
What cause this no response?? An SNMP query??



it looks like the MIBs are wrong.
so in this case I have two questions:

1. how do I find the correct MIBs? (yes, I could run SNMPwalk, but
I have no idea what I'm doing with that)


Follow the OID tree and hopefully you find via that the
correct MIB module.



2. once I do have them, how do I put them into checkrad without wrecking
the other cisco stuff (since they are both cisco)


Why would such a box need the MIB modules??
I beleive you want to place the MIB module somewhere on your manager
so your tools can do the translation on this side (not agent side).
Specifics of how depends on your tools.



I may (or may not) actually have a MIB string for the 7500, I don't 
undestand
what this stuff means, so I don't know what to do with it

You need to have a MIB module in order to know what a variable retrieved
from an SNMP agent means.


while on the topic of MIBs, can anyone tell me what this means or what
it could be used for:

1.3.6.1.4.1.9.10.19.1.1.4.0:public@usernas2


The prefix '1.3.6.1.4.1' means enterprises.
You could have found this easily yourselves by looking into
RFCs that specify the MIB module language (SMI) or most books
on the subject.

After that you have an enterprise specific OID which is 10.
That you can find in http://www.iana.org/assignments/enterprise-numbers

10

That seems to be NSC. No clue who or which company this is, but you can 
try
the email address that is the contact person. Possibly out of date.
Via him you could maybe get the MIB module definitions or ask where you
got the device from.

Then the part '19.1.1.4.0' seems to specify some scalar variable in
this domain.

'public' is the community

'@usernas' I guess the hostname.



I think this is the MIB for the IP pool on an AS500, which means it 
could be used
to keep track of how many users are online.

No clue.


Hope this helps,
