IDS 4215 not sending SHUN to PIX

[adminrdkeith]

Just installed a new IDS, Have enabled several default sig. Have telnet configured to PIX. Have verified using (who) in pix and it shows the IDS. Problem: IDS is not sending any SHUN statements to PIX. Is there anything in the PIX I need to set to allow the SHUN to work? Not sure what to look for next. Need suggestions Please??

Thanks

Have you made sure an alarm is firing and sending a block request to nac (network access controller)? Do a show events from the sensor cli. When the alarm fires there should also be an event requesting a shun(block).

When you enabled the sigs, what event action did you set, block connection or block host ?

Looked in events, it shows no event requesting a shun?

I enabled sigs by default, selecting the (attack) option. Cant seem to find the event action to block connection or block host?
