Is it possible to add a network sensor from the Genians NAC web gui to monitor on a trunk port? I see that the admin guide explains doing this in the initial configuration, but is it possible to add an additional network sensor after you have stood up the server/sensor.
I attempted to do this by using the cli command: interface eth1 vlan
Then adding the vlan id’s on the trunk port, but this does not seem to have worked for monitoring network traffic on those vlans. Additionally I added IP addresses for the different subnets on those vlans for the interface, but again this does not seem to have worked.
I made that change and my config now looks like this:
interface eth1.100 address 192.168.0.254 255.255.255.0
interface eth1.101 address xxx.xxx.xxx.xxx 255.255.255.0
interface eth1.102 address xxx.xxx.xxx.xxx.255.255.255.0
interface eth1 address 192.168.0.100 255.255.255.0
interface eth1 vlan 100,101,102
So now eth1.100 and eth1 both have an address within the same subnet – is this the way it should be or should I remove/change the IP on eth1 since it is really eth1.100 that I want to be monitoring the subnet?
