Introduction

This document provides port security configuration examples.

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.

·          You cannot disable port security when online users are present.

·          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 Ten-GigabitEthernet 1/0/1 to meet the following requirements:

·          The device accepts a maximum of 64 users to log in through the port without authentication.

·          After the number of users reaches 64, the port denies any new users to access the Internet.

Figure 1 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·          Configure the autoLearn mode on the port through which the users access the device. The access port is Ten-GigabitEthernet 1/0/1 in this example.

·          Configure an aging timer for the secure MAC addresses, so the device can update its secure MAC address table.

·          Configure Ten-GigabitEthernet 1/0/1 to shut down temporarily for 30 seconds when it receives illegal frames. The device can deny any new users to access the Internet after the number of online users reaches 64.

Restrictions and guidelines

Before you enable the autoLearn mode, set the maximum number of secure MAC addresses that port security allows on the port (by using the port-security max-mac-count command). You cannot change the setting when the port is operating in autoLearn mode.

Example: Configuring userLoginWithOUI mode

Network configuration

As shown in Figure 2:

·          Users use the 802.1X client on the host to initiate 802.1X authentication.

·          The device uses the RADIUS server to perform authentication, authorization, and accounting for all users in ISP domain sun.

·          IMC is the RADIUS server.

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

Configure port security mode userLoginWithOUI on the device to meet the following requirements:

·          Permit only one 802.1X user to pass authentication to access the Internet.

·          Permit the printer to access the Internet.

·          Discard all illegal frames without disabling the port security-enabled port.

Figure 2 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·          Configure the userLoginWithOUI mode on the port through which the users access the device. The access port is Ten-GigabitEthernet 1/0/1 in this example.

·          Add the printer's OUI to the port security module of the device, so the device can permit the printer to access the Internet in userLoginWithOUI mode. To match the OUIs of different printer vendors, add multiple OUIs to the device.

·          Configure the blockmac intrusion protection on Ten-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

In this example, the RADIUS server runs IMC PLAT 7.0 (E0201) and IMC UAM 7.0 (E0201).

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.

Example: Configuring macAddressElseUserLoginSecure mode

Network configuration

As shown in Figure 7, the device uses the RADIUS server to perform authentication, authorization, and accounting for all users in domain sun.

Configure port security mode macAddressElseUserLoginSecure on the device to meet the following requirements:

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

·          Perform MAC authentication first for an 802.1X user, and then 802.1X authentication if the user fails MAC authentication.

·          Use shared user account with username aaa and password 123456 for MAC authentication users.

·          Allow a maximum of 64 authenticated users.

·          Prevent frames from being sent to unknown MAC addresses.

Figure 7 Network diagram

 

Analysis

To meet the network requirements, you must perform the following tasks:

·          Configure the macAddressElseUserLoginSecure mode on the port through which the users access the device. The access port is Ten-GigabitEthernet 1/0/1 in this example.

·          Set the NTK mode to ntkonly, so the device will prevent frames from being sent to unknown MAC addresses. In this mode, the device permits only unicast frames that are destined for the authenticated MAC addresses.
