Rogue Sensor weirdness

Hi

A long time ago (in relative terms) I was the sole administrator of our ePO 4.5 installation with McAfee VSE 8.7 / 8.8

Since then it has been upgraded to ePO 4.6, and a lot of things have changed.

I don't have any change control, documentation or helpdesk tickets covering this.

What i've come back to is a mess, and i've been working my way through it.   One issue that has me stumped is our Rogue Sensors.

We had 1 per site, equating to one per subnet as each site is using a /24 subnet.

(eg:  rogue sensor for 10.7.6.0/24 and rogue sensor for 10.9.3.0/24 etc)

Previously, the Detected Systems tab would have all of these subnets split up logically on the left sidebar.

I've come back to this:

Does anyone have any idea how I can start troubleshooting this?

Any more information I can provide to assist?

thanks for your time.

Re: Rogue Sensor weirdness

You don't mention which ePO patch is installed, but it looks a lot like an issue which is resolved in ePO 4.6 Patch 3.

Per the patch 3 readme:

77.  Issue – Agents occasionally return incorrect ipV6subnet information that suggests all IPs in the network are in the subnet. (Reference: 699813)

Resolution – Invalid subnet records are removed upon installation of ePolicy Orchestrator 4.6.3. In addition, RSD ignores invalid subnet values from agents.

Rgds,

Rob.
