Hi Jeroen,
thanks for your reply. The netdisco 1.x is running with SNMP::INFO
version 2.01-1 from Ubuntu 10.04 repository. Netdisco 2.x ist running
with SNMP::INFO 3.28-1 on Debian with original SNMP::Ino from CPAN.
Regards,
Oliver

Sebastian, your SNMP community strings have an access-list on them, 10 in
this case. Try a 'show access-list 10'
My guess is that your netdisco server IP is not in that access-list.

Hi Oliver,
the same here with Avaya VSP 8000 and VSP 7200.
But this devices should support SONMP too, or?

Hello Oliver,
thanks for your answer.

Yes, you're right. The vsp4000 do not know anything about LLDP (*damn*). It
is on the Avaya roadmap for further enhancement. Until then we'll have to
add devices manually :-(

Thanks for thinking about an easy way to add new mibs.
Maybe it's possible to create a website where mibs can be uploaded and
processed so that the result can be shared with others that are using these
mibs. But maybe I'm not thinking very well and it's more complicated than I
can imagine :-)
