Pix Firewall infos

Hi,

I have a pix 515 and when I detected it, it got detected as a cisco terminal router...

I changed the type manually to cisco pix firewall...

By Default it got into workstations map...

I moved it routers map...

1- Why can't I see cpu usage ?
2- If I click on an interface, they are listed as UnManaged why ?
3- On each interfaces I click manage... I still cannot see any data neither graph...
4- Why can't I see the route table ?

Basically, are cisco pix supported beside just being able to add them to the web page :)
