So long as the PF server can communicate with the switch the node is on via the 
method you chose (SNMP or RADIUS) that is all that you need.

I have about 600 vlans and my PF server has 2 interfaces.  The management IPs 
of my switches can send and receive data to/from the PF server and it all just 
works.

Jake,

You are absolutely making sense. I will need to go over what you wrote a little 
more as you clearly are much better versed in all of this than I am but overall 
this sounds perfectly reasonable and what we need is likely simpler. And we are 
perfectly happy to re-authorize users who move from site to site so that should 
not be a problem.

Just one question: is the PF server expected to have all the VLAN's from all 
the sites? Or can that part be relegated to relevant switches?

Thanks for your input.

Boris.

PF makes the final vlan assignment based on the role and the switch you the 
node is connected to.

So to make sure the correct vlans get assigned set them up in the switch 
properties in PF.

For example:

Site A has 10 switches with Production (aka Normal) and Guest vlans.

Site B has 5 switches with Marketing, R&D, Guest, and HVAC vlans

In PF you will see all 15 switches, every switch will have a setting for every 
role PF knows about (Production, Guest, Marketing, R&D, HVAC).

On the switches for site A you would set the corect vlan ids for the Production 
and Guest vlans and you can leave the rest blank.

For site B you would set the vlan ID for the vlans available at that site 
(Marketing, R&D, Guest, and HVAC).

The vlan id for a given role need not be the same across switches, meaning that 
the Guest vlan id for site A does not need to be the same as the Guest vlan id 
at site B, etc..

Then you would setup rules and roles that would steer users into the correct 
role based on how they authenticate, or what ever other criterion you want.

When a user hits site A they will have their access evaluated based on the 
rules you created and be assigned the corresponding role and thus the correct 
vlan.

Your only trouble would be handling users moving to a site that does not know 
about their role.  For example is a user from site B that has been assigned the 
Marketing role went to site A where PF does not have any vlan setup for that 
role.

There are ways to deal with this but you get the idea.

In general PF is site unaware.  PF assumes all of your switches are on the same 
site.  Well, perhaps assumes is not the correct word, more like PF doesn't care 
where your switches are.

NAC can be a confusing subject, this is exacerbated by everyone not always 
using the same jargon.  I hope I'm actually answering your questions and not 
sounding like a fool.

Thanks for some great input!

OK, let us say I have a distributed network with multiple sites, and I can not 
have VLAN's spanning across multiple sites. So how do I define isolation and 
registration networks for each site even though my PF server is only available 
at one site (the hub)? Or do I need to even?

Boris.

Configuration | Switches | [pick one] | Roles

PF determines the role that each user has, and then passes that role to
the switch(es) to let them make the decision on what VLAN they need to
be on based on their role.  What VLAN a device should be placed on may
vary by switch, with an example being a multi-building network with
different VLANs in each.  You tell the switch what role a device is, and
it decides what VLAN to put it on.

In PF 3.x, there's a setting in the switch config called "Normal VLAN."
In PF4, it is called "default."  If you do not wish to use roles and want
everyone on the same production network, this is where you set that VLAN
on every switch...

Tim,

True enough - but given that there may be more than one - doesn't the PF server 
need to be aware of them and know how to tell the switch involved which VLAN to 
put the node in?

Boris.

100%. I should have said "one or more production networks".

Authorized clients don't necessarily get sent to the same areas just because

Hello all,

This is just to compare notes and make sure the way I do things is in line with 
the conventions. So here is how I understand things.

"Registration VLAN" is where newly plugged in devices are assigned, until they 
are deemed secure and allowed to join the production network.

"Isolation VLAN" is where suspect devices (those believed to be virus-infected, 
for instance) are relegated to.

"Management VLAN" is a network used for management purposes (to communicate to 
switches, etc.)

Here is what I don't quite understand.

1) Why is a "Production VLAN" not mandated?

2) How does one designate it on the switch level as a VLAN to put 
production-ready devices in (i.e., OK, MAC address so-and-so on port 10 is 
good, switch it to the "Production VLAN" and let is access the internet)?

Thanks in advance for your help.

Cheers,

Boris.
