Hp Procurve 802.1 X Configuration Example

So I'm learning about 802.1x authentication as a means of securing access to the LAN of a client who wants to be PCI compliant (and one part of PCI compliance is securing publicly accessible network jacks).

The environment consists of:

The authentication and accounting features can choose which RADIUS server group to communicate with. End-user authentication methods (802.1X, MAC-based and web-based) can authenticate with different RADIUS servers from the management interface authentication methods (console, telnet, ssh, web). Example of Configuring Client-Based 802.1X Authentication Example: Configuring Port-Based 802.1X Authentication This example enables ports A13-A15 to operate as authenticators, and then configures the ports for port-based authentication.

  • Windows 10 domain-joined PCs (and some not domain-joined)
  • VoIP phones
  • Receipt printers
  • Letter printers
  • Barcode printers
  • Credit card readers
  • Windows Server running NPS for RADIUS authentication
That said, these screenshots and notes will all come out of my home lab. Here's a link to my syntax source.

Installed NPS on a test server and told it that my test switch would be a RADIUS client. Created a wildcard 'Connection Request Policy' to accept the MAC address of a test Windows PC:
Told the switch what RADIUS server to use:
radius-server host key 'xxxxxx'
Configured ports 3 and 4 on the switch to require RADIUS authentication - and if RADIUS authentication doesn't happen for any reason, to drop a connected device onto VLAN 3:
aaa port-access authenticator 3-4 unauth-vid 3
aaa port-access authenticator 3-4 client-limit 2 #allows up to two devices per port
aaa port-access authenticator active
The switch offers both chap-radius and eap-radius..these are simply frameworks for transporting authentication to the server..for chap-radius to work, the user/computer password in Active Directory needs to be stored with reversible encryption (not the default), so eap-radius seems preferable.
Next, I started the 'Wired Autoconfig' service on the test Windows PC (you can do this via group policy in a production environment)..this service offers credentials to the switch for authentication by RADIUS..I learned (and you can see this in a Wireshark packet capture!) that when a computer boots up it'll try to authenticate with its computer account..and then after a user logs in, it re-authenticates with the logged-in user account. So cool, huh?

So far, no certificate was needed on the NPS server. However the Windows PC complained on its NIC that 'Authentication Failed' (but it was still given the 'authorized' VLAN due to the Connection Request Policy that I'd created).
So, how to fix this message? Created a Network Policy with an authentication method of PEAP:

Now the NIC was happy:

..and bear in mind that this is without any client-side certificates. I like that. Keeps it simple.
Next: get my VoIP phone working. However, when I plugged it into the switch, the switch never said a thing to the RADIUS server, instead it just dropped the phone into my unauthenticated VLAN (3).
The solution is to enable MAC authentication in the switch as a fall-back mechanism for when devices don't do 802.1x authentication. (Syntax source).
The first step of this was to disable something I'd done earlier:
no aaa port-access authenticator 3-4 unauth-vid
..then replace it with this:
aaa port-access mac-based 3-4 unauth-vid 3
This is because if 802.1x authentication fails on switch ports 3 or 4, then MAC address authentication will be tried..and if that fails, then the device will be dumped into VLAN 3 (my DMZ).
Let's support up to 2 devices per-port on ports 3 or 4 (e.g. a phone with a computer behind it):
aaa port-access mac-based 3-4 addr-limit 2
Now let's enable MAC address authentication for ports 3 and 4:
aaa port-access mac-based 3-4
Now we'll view status:
A VoIP phone was on port 4..disconnected / reconnected the phone's patch cable..it got a new IP from VLAN 3 and rebooted.
This was good. Now, how do I authorize it in NPS?

I'm using a wildcard MAC address here, and I got the format of the MAC address from a Wireshark packet capture:

So at this point I have a PC that authenticates via its computer account and a phone that authenticates via its MAC address. Yay!

We acheived to setup 802.1x+MAB on HP 2610 HP switches just like with
Cisco. As this is nearly undocumented, I want to share the information,
as it may be interesting to have it on official PF devices config guide.
The trick is to use aaa port-access authenticator x client-limit 1,
which allows multiple auth modes for a single client. With this setup,
802.1x auth is tried first, and if it fails, mac auth is performed.
radius-server host a.b.c.d acct-port 1813 key 'verysecret'
snmp-server host a.b.c.d community 'public' informs trap-level not-info
no snmp-server enable traps link-change x
aaa server-group radius 'packetfence' host a.b.c.d
aaa authentication port-access eap-radius server-group 'packetfence'
aaa authentication mac-based chap-radius server-group 'packetfence'
port-security x learn-mode port-access action send-alarm
aaa port-access authenticator x
aaa port-access authenticator x client-limit 1
aaa port-access authenticator active
aaa port-access mac-based x
aaa port-access mac-based x addr-moves
aaa port-access mac-based x reauth-period 14400
aaa port-access x controlled-direction in
The last line is supposed to allow WOL magic packets to be sent to the
port. Unfortunately it doesn't seems to work, I have to investigate this
issue, as I'm not sure that Magic packets are reaching the switch if
there is no untagged vlan matching WOL broadcast address configured on it.
