Re: snmp proxy to multiple devices with same oid using contextEngineId

Hi dave

Thanks for clarification. It works perfectly when I access the proxy with v3
and the remote agent with v3 aswell.



As I have an agent which only understands v2 with a specific community
string I tried the following:
(Just for testing proxy everything to the remote device)

proxy -Cn context1 -v2c -c public remotehost .1.3

(the cstring 'public' is set up on the remote host)

without any setup of com2sec, as - how I understand it - this is not needed
here.


Howewer calling the proxy with

snmpget -n context1 -v3 -u user proxyhost sysContact.0

results in a timeout.


calling the remotehost directly with

snmpget -v2c -c public remotehost sysContact.0

works.

Anybody nows what I do wrong?

Thanks a lot

Boris
