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.
