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.
Yes, It is possible to add a Network Sensor. Each Network Sensor can handle up to 128 VLANs.
Once configured you can add New Network Sensors by configuring them in the CLI.
You will need to configure an additional sub-interface, and VLAN ID for interface eth0.
interface eth0 vlan 1,10,15 (*Adding VLAN 15 for network 10.1.3.5)
interface eth0.3 address 10.1.3.5 255.255.255.0
Below is what your configs should look like.
# interface eth0.10 address 10.1.10.5 255.255.255.0
# interface eth0.15 address 10.1.15.5 255.255.255.0
# interface eth0 address 10.1.1.5 255.255.255.0
# interface eth0 gateway 10.1.1.1
# interface eth0 vlan 1,10,15
# interface eth0 management-server enable
# interface eth0 node-server enable
# interface eth0 radius-server enable
# interface wlan0 mode monitor
# ip default-gateway 10.1.1.1
# ip name-server 188.8.131.52
# log-server enable
# log-server cluster-name GENIAN
# ntp server pool.ntp.org
# system-locale en
