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.
Thanks Bill, it seems to be working now. One thing I noticed is the eth1 address (in my case I added another interface so its eth1 not eth0 that I am trying to do this on) does not seem to be reachable and not monitoring the subnet it is in. The trunk port has 3 vlan's (100,101,102) - eth1 is in 100 vlan. So my config currently looks like this:
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 xxx.xxx.xxx.xxx 255.255.255.0
interface eth1 vlan 100,101,102
vlan 100 is not a mangement vlan - do I need to add another interface IP to be able to monitor vlan 100 subnet?
i.e. - interface eth1.100 address xxx.xxx.xxx.xxx 255.255.255.0
