Configuring MACsec Encryption

MAC Security (MACsec) is the IEEE 802.1AE standard for authenticating and encrypting packets between two MACsec capable devices.

Security breaches can occur at any layer of the OSI model. Some of the common breaches at Layer 2 are MAC address spoofing, ARP spoofing, Denial of Service (DoS) attacks against a DHCP server, and VLAN hopping.

MACsec secures the data on physical media, making it impossible for data to be compromised at higher layers. As a result, MACsec encryption takes priority over any other encryption method for higher layers, such as IPsec and SSL.

MACsec provides encryption at the Layer 2, which is provided by the Advanced Encryption Standard (AES) algorithm that replaces the DES algorithm. MACsec uses the MACsec Key Agreement protocol (MKA) to exchange session keys, and manage encryption keys.

Understanding MACsec

MACsec Frame Format

The MACsec header in a frame consists of three fields.

Table 1. Fields in MACsec Frame

Field

Size

Description

SECTag

8 or 16 bytes

Identifies the Security Association Key (SAK) to be used to validate the received frame. The security tag also provides replay protection when frames are received out of sequence. With Secure Channel Identifier (SCI) encoding, the security tag is 16 bytes in length, and without the encoding, 8 bytes in length (SCI encoding is optional).

Secure Data

2+ octets

Data in the frame that is encrypted using MACsec.

ICV

128 bit

Integrity Check Value (ICV) that provides the integrity check for the frame. Frames that do not match the expected ICV are dropped at the port.

MACsec Key Agreement

The MACsec Key Agreement (MKA) Protocol, defined in IEEE 802.1X-2010, provides the required session keys and manages the required encryption keys. MKA is a multipoint to multipoint protocol that defines the mechanism to generate and distribute keys for MACsec.

MKA allows authorized multiple devices that possess secret key (CAK) to participate in a CA (Connectivity Association). It defines the election of Key Server (KS) that generates the Security Association Key(SAK) and distributes the SAK to all the participants. MACsec frames across the devices are secured using SAK. MKA also transports MACsec capability such as delay protection and confidentiality offset.

MKA operates in two modes.

MACsec in NCS 1002

MACsec in NCS 1002 has the following characteristics or limitations.

  • Supports 256-bit Extended Packet Numbering (XPN) according to IEEE 802.1AEbn-2011.

  • Supports GCM-AES-XPN-256 as the default cipher.

  • Supports AES-128-CMAC and AES-256-CMAC cryptographic algorithms.

  • Supports SecY function in the data plane as specified by IEEE 802.1 AE-2006 specification.

  • Supports only 2 x 100G client and 1 x 200G trunk traffic.

  • Supports only cumulative statistics for MACsec counters.

  • Supported only with the ncs1k-k9sec package.

  • Not supported in the headless mode.

  • Recommended to upgrade the nodes to R6.2.1 and bring up the 100G MACsec sessions.

  • For 100G MACsec deployed in R6.1.1 and R6.1.2: If the customer migrates from R6.1.2 to R6.2.1, traffic hit occurs. The subsequent headless operations will not have any traffic drops.


Note

When the user needs to use the MACsec feature and upgrades from R6.0.1 to 6.1.1, the control FPGA (CTRL_BKP_UP, CTRL_BKP_LOW, CTRL_FPGA_UP, and CTRL_FPGA_LOW) needs to be upgraded to the latest firmware version provided by R6.1.1. See Verify Firmware Version for more information.

MACsec Key Chain

A MACsec key chain is a collection of keys used to authenticate peers needing to exchange encrypted information. While creating a key chain, we define the key(s), key string with password, the cryptographic algorithm, and the key lifetime.

  • The key can be up to 64 characters in length.

  • The key name must be of even number of characters. Entering an odd number of characters will exit the MACsec configuration mode. The key name must match on both the sides.

  • The key string is 64 hexadecimal characters in length when AES 256-bit encryption algorithm is used and 32 hexadecimal characters in length when AES 128-bit encryption algorithm is used. It is recommended to create key name and provide the key-string and lifetime.

  • The lifetime period (validity period of the key) can be configured, with a duration in seconds, as a validity period between two dates (for example, Jan 01 2016 to Dec 31 2016), or with infinite validity. The key is valid from the time you configure (in HH:MM:SS format). The duration is configured in seconds. The overlapping time must be configured in two keys to avoid traffic loss.

  • The keys roll over to the next key within the same key chain by configuring a second key (key 02) in the key chain and configuring lifetime for the first key. When the lifetime of the first key (key 01) expires, it automatically rolls over to the next key in the list. If the same key is configured simultaneously on both sides of the link, the key rollover is hitless and the key rolls over without interruption in traffic. Based on IEEE 802.1x, the overlapping time between the keys in a key chain can be up to 20 seconds. The re-key operation can take up to 16 seconds.

MACsec Policy

You apply a defined MACsec policy to enable MKA on the controller. You can configure these parameters for MACsec policy:

  • Policy name, not to exceed 16 ASCII characters.

  • Confidentiality (encryption) offset of 0 bytes.

  • Replay protection. You can configure MACsec window size, as defined by the number of out-of-order frames that are accepted. This value is used while installing the security associations in the MACsec. A value of 0 means that frames are accepted only in the correct order.

  • The cipher suite to be used for MACsec encryption is GCM-AES-XPN-256.

  • The range of key server priority parameter is 0 to 255. Lower the value, higher the preference to be selected as the key server.

  • The security-policy parameter configures the type of traffic (encrypted traffic or all traffic) that is allowed through the controller configured with MACsec. The default value of security-policy parameter is must-secure that indicates unencrypted packets cannot be transmitted or received except MKA control protocol packets.

MACsec Controllers

MACsec controllers are created when a slice is provisioned with the encrypted keyword. The MACsec controller is used to configure the MACsec parameters. All the MACsec statistics is available on the MACsec controller. The MACsec controller is represented in the Rack/Slot/Instance/Port format, for example, 0/0/0/3.

A unique MAC address is generated for each MACsec controller. When software is upgraded to R6.2.2 with traffic, traffic loss occurs for the slice configured in encrypted mode.

Configure the Slice

You can configure the slice with traffic on client and trunk ports. All five client ports of the slice need to be configured at the same bitrate except for mixed mode configuration. Both the trunk ports are always set with the same FEC mode. The slice can be configured to send encrypted traffic from R6.1.1.

See the Supported Configurations in Encrypted Mode section to determine the supported configurations on the client and trunk ports in each slice configured in encrypted mode


Note

When the slice is configured in encrypted mode, the drop-lldp cannot be enabled.


Note

When NCS 1002 is installed in a system where both the trunk interfaces in a slice are used, the two 250Gb 16QAM signals need to be co-routed on the same fiber (mandatory when the 5x100Gb client port is provisioned). Also, it is recommended to use adjacent wavelengths when the line modulation is set to 250Gb 16QAM. The reason for this is that the chromatic dispersion generates skew between wavelengths. Assuming a Dispersion of 10000 ps/nm, a span of 500 km, and using adjacent channel, the skew is evaluated in less than 200 ns and it is compensated by the deskew capability of NCS 1002. If the delta between the used channels is increased, the skew increases and it might exceed the skew compensation done by NCS 1002.

To configure the slice with unencrypted traffic, use the following commands.

configure

hw-module location location slice [slice_number | all ] client bitrate { 10G | 40G | 100G } trunk bitrate { 100G | 200G | 250G } fec { softdecision7 | softdecision20 }

commit

To configure the slice with mixed mode, use the following commands.

configure

commit

To configure the slice with encrypted traffic, use the following commands.

When a slice is configured with 10G client rate in encrypted mode, ten MACsec controllers are created for each slice. When all the four slices are configured with 10G client rate in encrypted mode, forty MACsec controllers are created for NCS 1002. Two MACsec controllers are created for the middle port, four controllers for the fourth port, and four controllers for the fifth port per slice.

Note

Until R6.3.2, if the user wants to modify the slice configuration using the hw-module command, the existing slice must be deleted and new slice must be configured. From R6.5.1, the user can directly change the existing parameters on the configured slice without deleting the slice.

The slice configuration can be done using hw-module configuration or terminal-device configuration. However, the hw-module configuration cannot be modified or deleted using the terminal-device configuration and vice versa.

Displays the details of the slice such as the slice ID, client rate, trunk rate, and the traffic percentage carried on the trunk ports. The Encryption Supported field indicates whether the slice is provisioned with firmware that supports encryption or not.

Note

 

The HW Status field might display "Need Upgrade" when the user needs to use the MACsec feature and upgrades from R6.0.1 to 6.1.1. Hence, the control FPGA (CTRL_BKP_UP, CTRL_BKP_LOW, CTRL_FPGA_UP, and CTRL_FPGA_LOW) needs to be upgraded to the latest firmware version provided by R6.1.1. See Verify Firmware Version for more information.

The Provisioned status does not indicate that the traffic can flow immediately. For example, use the show controllers maCSecCtrlr 0/0/0/3 command output to view the provisioning information of the port after the slice is provisioned.

Verify State of MACSec Controller

The state of MACSec controller can be verified using the show controllers MACSecCtrlr R/S/I/P command. If the state of MACSec controller is down, the corresponding MKA sessions do not come up.

The state of MACSec controller is down upon one of the following conditions.

  • State of the corresponding Ethernet controller is Admin Down. The state can be verified using the show controllers HundredGigECtrlr R/S/I/P command.

  • State of the optics controller is Admin Down or Operational Down. The state can be verified using the show controllers optics R/S/I/P command.

  • Client optics is not present. The client optics can be verified using the show inventory command.

The state of the Ethernet controller can be changed from Admin Down using the following commands. 


configure
controller HundredGigECtrlr Rack/Slot/Instance/Port
no shutdown

Configuring MACsec Threshold Crossing Alerts

You can configure MACsec Threshold Crossing Alerts (TCA) at mac-sec ether, secy-if (interface), and secy-tx. There is no default threshold, mimimum or maximum threshold for configuring MACsec TCA. You can configure it between the range 1 to 4294967295. By default, you can find TCA in show logging command. You can configure syslog server in MACsec TCA, and view TCA in syslog server such as EPNM speicific parameter. You can set TCA for all supported buckets such as 0-sec/15-mins/24-hour for parameters in mac-sec ether/ secy-if/ secy-tx, secy-rx.

Use the following command to configure the MACsec Threshold Crossing Alerts (TCA) at MACsec ether layer, MACsec-secy-if, MACsec-secy-Tx, and /or MACsec-secy-Rx:

controllers macSecCtrlr R/S/P {pm {30 sec | 15-min | 24-hour} {macsec-ether | macsec-secy-if | macsec-secy-tx | macsec-secy-rx}{report | threshold {in-oct-decrypted | out-oct-decrypted} value} enable

Examples

The following is a sample to configure the MACsec TCA parameters for rx-pkt at macsec-ether level for MACsec controller in 15 min intervals: 

controllers macSecCtrlr 0/0/0/11/1
 pm 15-min macsec-ether report rx-pkt enable
pm 15-min macsec-ether threshold rx-pkt 1000000

The following is a sample to configure the MACsec TCA parameters for rx-util at macsec-ether level for MACsec controller in 15 min intervals: 

controllers macSecCtrlr 0/0/0/11/1
pm 15-min macsec-ether report rx-util enable
pm 15-min macsec-ether threshold rx-util 10

The following is a sample to configure the MACsec TCA parameters for out-octets at macsec-ether level for MACsec controller in 15 min intervals: 

controllers macSecCtrlr 0/0/0/11/1
pm 15-min macsec-ether report out-octets enable
pm 15-min macsec-ether threshold out-octets 100000

The following is a sample to configure the MACsec TCA parameters for rx-pkt at MAC-SECy-If controller in 30 sec interval: 

controller MACSecCtrlr0/0/0/4
pm 15-min macsec-ether report rx-pkt enable
pm 15-min macsec-ether threshold rx-pkt 1000

Clear Commands

You can use the following commands to clear the PMs across different buckets:

clear controller macSecCtrlr 0/0/0/10 pm 15-min
clear controller macSecCtrlr 0/0/0/10 pm 30-sec
clear controller macSecCtrlr 0/0/0/10 pm 24-hour

View MACsec PM Parameters

You must configure MACSec controllers to view MACsec performance. To configure MACSec controllers , seeApply MACsec Configuration on MACsec Controller.

Use the following commands to view the MACsec performance monitoring at MACsec ether layer, MACsec-secy-if, MACsec-secy-Tx, and /or MACsec-secy-Rx:

show controllers macSecCtrlr R/S/P{ pm{current |history} { 30 sec |15-min | 24-hour } {macsec-ether | macsec-secy-if | macsec-secy-tx | macsec-secy-rx}

MACsec MKA Using EAP-TLS Authentication

Using IEEE 802.1X port-based authentication with Extensible Authentication Protocol (EAP-TLS), MACsec MKA can be configured between two NCS 1002 device ports. EAP-TLS allows mutual authentication and obtains MSK (master session key or primary session key). Both Connectivity Association Key Name (CKN) and connectivity association key (CAK) are derived from MSK for MKA operations. The device certificates are carried for authentication to the external AAA server using EAP-TLS.

IEEE 802.1X Device Roles

The devices in the network have the following specific roles with IEEE 802.1X authentication.

  • Supplicant - An entity at one end of a point-to-point LAN segment that seeks to be authenticated by an Authenticator attached to the other end of that link.

  • Authenticator - An entity that facilitates authentication of other entities attached to the same LAN.

  • Authentication Server - An entity that provides an authentication service to an Authenticator. This service determines, from the credentials provided by the Supplicant, whether the Supplicant is authorized to access the services provided by the system in which the Authenticator resides.

Prerequisites for MACsec MKA Using EAP-TLS Authentication

  • Ensure that a Certificate Authority (CA) server is configured for the network.

  • Ensure a valid CA certificate.

  • Ensure that the user has configured Cisco Identity Services Engine (ISE) Release 2.2 onwards or Cisco Secure Access Control Server Release 5.6 onwards as external AAA server.

  • It is always good to have the NCS 1002 devices, the CA server, and the external AAA/Radius server synchronized using Network Time Protocol (NTP) Server. If clock is not synchronized, there might be instances where certificate validation will not be successful, due to timing issues.

    However, there is no dependency on the timezone between NCS 1002 devices, the CA Server and the external AAA/Radius server.

Authenticate Certificate Authority and Request Certificates

This procedure authenticates the certificate authority (CA) with NCS 1002 and requests certificates from the CA. NCS 1002 must authenticate the CA by obtaining the self-signed certificate of the CA. The self-signed certificate contains the public key of the CA. It is required to manually authenticate the public key of the CA by contacting the CA administrator to compare the fingerprint of the CA certificate.
