I'm involved in the following setup illustrated below. I am Site 4. I have a SIP trunk via the CUBE to Site 3. Calls route between Site 4 and Site 1 with no problem. Is it possible to use Site 1 CUCM, to route calls from Site 4 to Sites 3 or 2? Is it...

Firepower FTD CPU 07 spiked to 100% earlier today. And it corresponds to the same time there was a spike on snort03. Snort-busy Frame drops - Snort busy started averaging 100 drops/sec.Is there a way for me to identify what traffic may have started t...

I have configured a rule in the Default NAC that is supposed to block a Layer 7 protocol application. When I analyze hit counts, it shows the rule has been matched. And when I analyze connection events, the traffic is showing as dropped. This is the ...

I thought I had tried "no capture cap-asp" that already, but it took this time. What I did differently this time was exit out of Lina and then connected back to FTD. Thank you.

What is the no form of the "capture cap-asp" command. Because I stopped it and wanted to redo it. I tried configuring another capture, but it says "error: another capture associated with this drop"

@MHM Cisco World , if I understand you correctly. In order to keep the rule as it is configured and still be able to use Packet Tracer, the deny rule for the application protocol needs to moved to the bottom. So basically right before the Deny All st...

I really wish I could, so you could see what I see. But I'm on a closed network. I have tested some of my other rules, that are blocking. So I know they work. I just don't know why Packet tracer isn't matching properly. I think I will have to open a ...
