What was the purpose/function of devSNMP ?

It provides device support for some of the standard EPICS record types
that permits them to do SNMP queries to other devices. We intend to
use it to make the state of our network switches available as PVs
through Channel Access.
I'm not sure what the correct SNMP terminology is, but this is an SNMP
client not a server (it fetches information rather than exporting it),
so it doesn't sound like it's what you're looking for.

We are currently also working on devSNMP scanning the MIBs from our SUN
and Linux machines. Scanning the (Cisco) network switches is the next
step. Albert Kagarmanov is working on this on our side. I wonder whether
we are talking the same devSNMP - hope so! - Let's check next week when
I am at ANL...
SNMP-Server (not the right term but best to understand the
functionality) for VxWorks IOC's would be really useful. The current
implementations are commercial and really expensive. Is Emmanuel
volunteering to implement one? This way we could get symmetric
information from the CA-client and - server machines. Which includes
network load etc. besides the well known CPU/Mem/FileDesc... we all get
via channel access from the EPICS-IOC's.
