Q: When I make any Interface settings changes, on the DC, all of the interfaces stop seeing traffic. How do I fix this?

A:

Sourcefire is working on fixing this problem, where all of the sensing interfaces on an IS stop seeing traffic after the interfaces settings page has been accessed on the DC. The current workaround is to restart the detection engines on the sensors. It's not necessary to reboot the entire sensor; just do this on the IS: /etc/rc.d/init.d/controlde stopall /etc/rc.d/init.d/controlde startall
