1. Overview: Medical Device Authentication

using Identify Engines

This document provides the framework for implementing device level authentication controls.

Future documents will build on this as a base to further define pre-canned solutions that utilize

device level authentication.

1.1 Access Layer

Any of the following access layer switches that can be used with Ignition Server for device

authentication. However, only the ERS5500 or ERS5600 series can be used if User Access

Policies are also required allowing the RADIUS server to tell the switch what policy to apply for a

specific user or device.

ERS5500

ERS5600

ERS4500

ERS2400

1.2 Ignition Server –Biomedical Device Authentication

For the Ignition Server to authenticate biomedical devices from an EAP authenticator, it must

know the device identity (typically the MAC address). In an existing network consisting of many

biomedical devices, most likely each device identity will not be known, thus making it very difficult

to authorize each device based solely on the full MAC address. Avaya’s Ignition Server can be

configured for device authentication using just the prefix of the biomedical manufacturer’s vendor

MAC. In turn, the Ignition Server can keep a data base of the full MAC address of each device

once it is authenticated by the Ignition Server.

The following is a list of top biomedical manufacturers vendor MAC’s.

1.3 Configuration Examples

Although any Avaya switch as shown in Section 1.1 could be used, for this example, we will use

an ERS5520 for allow for both device authentication with or without policy.

1.4 Biomedical Device Authentication using Identify

Engines Ignition Server and ERS5500

For this example, we will demonstrate how to configure the Ethernet Routing Switch 5500 and

Ignition Server to allow for device authentication based on the biomedical manufacturer vendor

MAC address. This will allow authentication and VLAN separation of manufacturer traffic. All that

is required is the first three digits of the vendor MAC address for the Ignition Server to

authenticate the device and then tell the EAP authenticator (ERS 5520 in this example) what

VLAN to place the biomedical device in (we will use Philips and Siemens for this example).

The Ethernet Routing Switch 5500 can be configured to accept both EAP and non-EAP (NEAP)

on the same port. In regards to non-EAP, the switch can be configured to accept a password

format using any combination of IP address and MAC address with or without port number. By

default, the password format is set for IP address, MAC address, and port number. For this

example, Ignition Server will be configured for device authentication so it is not important how the

password format is configured on the ERS 5520. However, it is suggested to use a password

format of MAC address so that if the complete MAC address is known, we can use user

authentication versus device authentication on Ignition server.

Overall, we will configured the following

Enable NEAP on ports 14 to 20 of ERS5520 using the non-EAP password format of MAC

address only

Add VLAN 1500 for the Philips devices

Add VLAN 1600 for the Siemens devices

Add VLAN 3000 as the default VLAN everyone connects to until authenticated by Ignition

Server

Configure the Ethernet Routing Switch 5520 and Ignition server with shared key set to

nortel

Add the recommended settings for connectivity to an SMLT Cluster –VLACP and

Multilink Trunking (MLT) with Spanning Tree disabled on the uplink core ports 23 and 24

1.4.1 ERS Switch Configuration

1.4.1.1 Go to configuration mode.

ERS5520-1 Step 1 - Enter configuration mode

5520-24T-PWR> enable

5520-24T-PWR# configure terminal

5520-24T-PWR(config)# cmd-interface cli

5520-24T-PWR(config)# banner disable

5520-24T-PWR(config)# snmp-server name 5520-24T-1

1.4.1.2 Create VLAN‟s

ERS5520-1 Step 1 –Create VLAN‟s 201, 1500, 1600, and 3000

5520-24T-1(config)# vlan create 201 name mgmt type port

5520-24T-1(config)# vlan create 1500 name philips type port

5520-24T-1(config)# vlan create 1600 name siemens type port

5520-24T-1(config)# vlan create 3000 name general type port

ERS5520-1 Step 2 –Enable VLAN tagging on all appropriate ports

5520-24T-1(config)# vlan port 23-24 tagging tagall

ERS5520-1 Step 3 –Set VLAN configuration control to automatic, add VLAN port

members, and set the management VLAN to VLAN 201

5520-24T-1(config)# vlan configcontrol automatic

5520-24T-1(config)# vlan members add 201 23-24

5520-24T-1(config)# vlan members add 1500 23-24

5520-24T-1(config)# vlan members add 1600 23-24

5520-24T-1(config)# vlan members add 3000,14-20,23-24

5520-24T-1(config)# vlan mgmt 201

ERS5520-1 Step 4 –Remove port members from the default VLAN

5520-24T-1(config)# vlan members remove 1 14-20,23-24



Please note that the non-EAP devices must be a member of a VLAN for the switch to

authenticate the devices. You can either leave port member 14-20 in VLAN 1 or create

a separate VLAN and add the port members as we have done by creating VLAN 3000.

ERS5520-1 Step 1 –Set the IP address of the switch

5520-24T-1(config)# interface vlan 201

5520-24T-1(config-if)# ip address 47.133.56.66 netmask 255.255.255.0

ERS5520-1 Step 1 –Add the default route

5520-24T-1(config)# ip routing

5520-24T-1(config)# ip route 0.0.0.0 0.0.0.0 47.133.56.1 1

1.4.1.8 Configure RADIUS server

ERS5520-1 Step 1 –Add RADIUS server using key „nortel‟

Enter key: ******

Confirm key: ******



Please note that at this time, non-EAP MAC RADIUS accounting is not supported.

Hence this example does not include the step to enable RADIUS accounting. If you

wish, you can enable RADIUS accounting using the command radius accounting

enable.
