You will need 1 NAC Profiler Appliance and one Collector license to enable Collector services on your exsiting. NAC Server

Hi James,

I would like to know whether you have any document or list of syntax for endpoint profiling on printers? I mean like the search data for the DHCP Client vendor.. etc..

Hi, We have several canned profiles built into Profiler already. Most profiles are based on well known ports that print servers will use and DHCP vendor information that the manufacturer has included for DHCP requests.

  • Cisco Employee,

We don't keep a documented list today. You can however create your own Profile by "sniffing" the DHCP traffic from the printer and matching the vendor information on the request and offer.

Thanks. How does Profiler perform behavior monitoring like if there is a mac spoofing, how does that work.

We are looking to deploy NAC globally. 3 core sites with NAC in a primarily centralized OOB Layer 3 model. This is for about 10 CAS's per site. Does each CAS set have to have Collector licenses, or can a one or two set's serve as the collectors?

Question over the NAC Appliance, not specifically the Profiler.

How do you recover the Admin password for the WebGui.. SSH username and password are known. Reason is we will upgrade from 4.0.5 to However the WebGui (admin) password is required and also unknown.

It is ok we have solved this issue. Thanks for you assistance. Resolution was via ssh, update the tomcat-users.xml with an hash entry (that was known). "Service perfigo restart".. Webgui works fine.

Is it possible to scale profiler above 40K devices? If so, how is that designed?

In detecting a spoofed MAC address, does the profiler have to be off of a SPAN port? Basically, what are the pros/cons of having the collector local vs having it remote (Via multiple L3 hops?)

Are you not able to do SSH login via Physical IPs or Service IP (HA IP) ?

Hello Syed, it was a issue with the SecureCRT. I did SSH with Putty and it worked. Then i tried again with SecureCRT but only with the Password option on the Autentication Options.

Thanks for you interest

There will be a iptables firewall service running on the profiler. Try stopping(service iptables stop) that and do the ssh, you should be able to.
