SNMP Proxy

Some machines are not directly available for monitoring. For these machines, use SNMPD Proxy. A reachable SNMPD then forwards the requests to the unreachable SNMPD.

Example configuration

This example polls 'unreachable.example.com' through

'hereweare.example.com'. Use this configuration.

On 'hereweare.example.com':

        view all included .1
        com2sec -Cn ctx_unreachable readonly <poller-ip> unreachable
        access MyROGroup ctx_unreachable any noauth prefix all none none
        proxy -Cn ctx_unreachable -v 2c -c private unreachable.example.com  .1.3

On 'unreachable.example.com':

        view all included .1                               80
        com2sec readonly <hereweare.example.com ip address> private
        group MyROGroup v1 readonly
        group MyROGroup v2c readonly
        group MyROGroup usm readonly
        access MyROGroup "" any noauth exact all none none

You can now poll the community 'private' on 'unreachable.example.com' through the community 'unreachable' on the host 'hereweare.example.com'. Note: the requests on 'unreachable.example.com' come from 'hereweare.example.com', not from your poller.
