Port security combines and extends 802.1X and MAC authentication to provide MAC-based network access control. The feature provides the following functions:

· Prevents unauthorized access to a network by checking the source MAC address of inbound traffic.

· Prevents access to unauthorized devices or hosts by checking the destination MAC address of outbound traffic.

· Controls MAC address learning and authentication on a port to make sure the port learns only source trusted MAC addresses.

Port security supports the following categories of security modes:

· MAC learning control—Includes two modes: autoLearn and secure. MAC address learning is permitted on a port in autoLearn mode and disabled in secure mode.

· Authentication—Security modes in this category implement MAC authentication, 802.1X authentication, or a combination of these two authentication methods.

Prerequisites

The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

This document assumes that you have basic knowledge of port security.

General restrictions and guidelines

When you configure port security, follow these restrictions and guidelines:

· Disable global 802.1X and MAC authentications before you enable port security on a port.

· Port security automatically modifies the following 802.1X or MAC authentication settings for different security modes:

¡ The status of 802.1X and MAC authentication.

¡ The 802.1X access control method.

¡ The 802.1X port authorization state.

· Disabling port security on a port will log off all online users on that port.

· Port security modes are mutually exclusive with link aggregation and service loopback group.

· The maximum number of users a port supports equals the smaller value from the following values:

¡ The maximum number of secure MAC addresses that port security allows.

¡ The maximum number of concurrent users the authentication mode in use allows.

For example, if 802.1X allows more concurrent users than port security's limit on the number of MAC addresses on the port in userLoginSecureExt mode, port security's limit takes effect.

· To change the security mode of a port security-enabled port, you must use the undo port-security port-mode command to set the port in noRestrictions mode first.

Example: Configuring autoLearn mode

Network configuration

As shown in Figure 1:

· Configure port security mode autoLearn on GigabitEthernet 1/0/1 to allow users to access the network without authentication.

· Configure the port to accept a maximum of 64 users (secure MAC addresses) to access the network. After the number of secure MAC addresses reaches 64, the port stops learning secure MAC addresses and no new user can access the network.

· To prevent inactive users from using secure MAC address entries, configure a secure MAC address aging timer.

· Configure GigabitEthernet 1/0/1 to shut down temporarily for 30 seconds when a new user accesses the network after the number of secure MAC addresses reaches 64.

Example: Configuring userLoginWithOUI mode

Network configuration

As shown in Figure 2:

· An 802.1X user on a host and a printer are attached to port GigabitEthernet 1/0/1 on the device.

· The device uses a RADIUS server (IMC in this example) to perform authentication, authorization, and accounting for all users in ISP domain sun.

· The device and the server use the shared key expert for secure RADIUS communication.

Configure port security mode userLoginWithOUI on port GigabitEthernet 1/0/1 to meet the following requirements:

· Permit only one 802.1X user to pass authentication.

· Permit the printer to access the Internet.

For the printer to pass authentication, add its OUI to the OUI list of port security.

Configure the blockmac intrusion protection action on GigabitEthernet 1/0/1, so the device adds the source MAC addresses of illegal frames to the blocked MAC address list. The device discards all frames sourced from the blocked MAC addresses.

Procedures

Configuring the RADIUS server

This example uses IMC PLAT 7.0 (E0201) and IMC UAM 7.0 (E0201) to describe the procedure.

1. Add the device to IMC as an access device:

a. Click the User tab.

b. From the navigation tree, select User Access Policy > Access Device Management > Access Device.

c. Click Add.

The Add Access Device page opens.

d. In the Access Configuration area, configure the following parameters:

- Enter 1812 in the Authentication Port field, and enter 1813 in the Accounting Port field.

- Select LAN Access Service from the Service Type list.

- Select HP(Comware) from the Access Device Type list.

- Enter expert in the Shared Key and Confirm Shared Key field.

- Use the default values for other parameters.

e. In the Device List area, click Select or Add Manually to add the device at 192.168.0.34 as an access device.

You must specify the source IP address of outgoing RADIUS packets on the device as the IP address of the access device on the server.

On the device, the source IP address is configured by using the nas-ip or radius nas-ip command. The IP address configured by using the nas-ip command has a higher priority than the IP address configured by using the radius nas-ip command. If no IP address is specified as the source IP address, the IP address of the packet outbound interface is used as the source IP address. In this example, the IP address of the packet outbound interface is used, which is 192.168.0.34.

f. Click OK.

Example: Configuring macAddressElseUserLoginSecure mode

Network configuration

As shown in Figure 7:

· Users on hosts are attached to port GigabitEthernet 1/0/1 on the device.

· All MAC authentication users use a shared user account with username aaa and password 123456TESTplat&!.

· The device uses a RADIUS server (IMC in this example) to perform authentication, authorization, and accounting for all users in domain sun.

· The device and the server use shared key expert for secure RADIUS communication.

Configure port security mode macAddressElseUserLoginSecure on port GigabitEthernet 1/0/1 to meet the following requirements:

· Allow only one 802.1X user to pass authentication, and allow multiple MAC authentication users to pass authentication.

· MAC authentication has a higher priority than 802.1X authentication. For an 802.1X user, the device initiates MAC authentication first, and then 802.1X authentication if the user fails MAC authentication. For a MAC authentication user, the device initiates only MAC authentication.

Configure port GigabitEthernet 1/0/1 to accept a maximum of 64 authenticated users.

Set the NTK mode to ntkonly mode on port GigabitEthernet 1/0/1 to prevent outbound frames from being sent to unknown MAC addresses.

Network configuration

As shown in Figure 11:

· Users on hosts are attached to port GigabitEthernet 1/0/1 on the device. All MAC authentication users use a shared user account with username dot1x and password Abc123!.

· The device acts as the NAS and a ClearPass RADIUS server performs remote authentication, authorization, and accounting for all users in domain sun. If a user passes authentication, the ClearPass server assigns a redirect URL to that user for Web authentication.

Configure port security mode macAddressElseUserLoginSecureExt on port GigabitEthernet 1/0/1 to meet the following requirements:

· Allow multiple 802.1X users and MAC authentication users to pass authentication.

Set the NTK mode to ntkonly mode on GigabitEthernet 1/0/1 to prevent outbound frames from being sent to unknown MAC addresses.

<Device> system-view

[Device] radius scheme radsun

New RADIUS scheme.

# Specify the server at 192.168.0.38 as the primary RADIUS authentication server.

[Device-radius-radsun] primary authentication 192.168.0.38

# Specify the server at 192.168.0.38 as the primary RADIUS accounting server.

[Device-radius-radsun] primary accounting 192.168.0.38

# Set the authentication shared key to expert in plain text for secure communication between the device and the RADIUS server.

[Device-radius-radsun] key authentication simple expert

# Set the accounting shared key to expert in plain text for secure communication between the device and the RADIUS server.

[Device-radius-radsun] key accounting simple expert

# Exclude domain names from the usernames sent to the RADIUS server.

[Device-radius-radsun] user-name-format without-domain

# Specify 192.168.0.34 as the source IP address of outgoing RADIUS packets.

[Device-radius-radsun] nas-ip 192.168.0.34

[Device-radius-radsun] quit

# Create ISP domain sun and enter ISP domain view.

[Device] domain sun

# Configure ISP domain sun to use RADIUS scheme radsun for authentication, authorization, and accounting of all LAN users.

[Device-isp-sun] authentication lan-access radius-scheme radsun

[Device-isp-sun] authorization lan-access radius-scheme radsun

[Device-isp-sun] accounting lan-access radius-scheme radsun

[Device-isp-sun] quit

# Specify ISP domain sun as the default domain.

[Device] domain default enable sun

3. Configure port security:

# Enable port security globally.

[Device] port-security enable

# Set the port security mode to macAddressElseUserLoginSecureExt and set the NTK mode to ntkonly on GigabitEthernet 1/0/1.

[Device] interface gigabitethernet 1/0/1

[Device-GigabitEthernet1/0/1] port-security port-mode mac-else-userlogin-secure-ext

[Device-GigabitEthernet1/0/1] port-security ntk-mode ntkonly

[Device-GigabitEthernet1/0/1] quit

# Configure a shared account for MAC authentication users, and set the username to dot1x and password to plaintext string of Abc123!.

[Device] mac-authentication user-name-format fixed account dot1x password simple Abc123!

# Enable the access device to terminate EAP packets and perform PAP authentication with the RADIUS server.

[Device] dot1x authentication-method pap

4. Configure advanced ACL 3001 to permit traffic destined for the redirect URL. The redirect URL is the address of the ClearPass server. Make sure the ACL number is the same as that assigned by the ClearPass server.

[Device] acl advanced 3001

[Device-acl-ipv4-adv-3001] rule 0 permit ip destination 192.168.0.38 0

[Device-acl-ipv4-adv-3001] quit
