Procurve Manager 3.10 scans external networks

We have installed Procurve Manager (latest release with updates: PCM C.03.10.201) on a WinXP PC a few days ago. Now we've received security alerts from other sites elsewhere in our country which report that the PCM host is portscanning their devices on port 161 (SNMP). I have no clue as to why PCM apparently attempts to discover devices on non-local networks, and I've not been able to find any configuration item in the PCM GUI which can be used to restrict device discovery to our local subnet only.

Question: How can one configure PCM to restrict device discovery to only specific (local) subnets ?

Hello Ole,

according to my experience the PCM will never add any remote subnets by itself. You have to add them manually to the discovery agent.
Please doublecheck your discovery settings:
Agent manager | Discovery | Managed Subnets
If the subnet is set to "unmanaged" the PCM should not touch these ranges with SNMP. Is this the case for your remote subnet?

Cheers,

Michael
