Chapter 1 Configuring MACsec Encryption
Configuring MKA and MACsec
Configuring MACsec on an Interface
Beginning in privileged EXEC mode, follow these steps to configure MACsec on an interface with one
MACsec session for voice and one for data:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface interface-id Identify the MACsec interface, and enter interface configuration mode.
The interface must be a physical interface.
Step 3 switchport access vlan vlan-id Configure the access VLAN for the port.
Step 4 switchport mode access Configure the interface as an access port.
Step 5
macsec Enable 802.1ae MACsec on the interface.
Step 6
authentication event linksec fail action
authorize vlan
vlan-id
(Optional) Specify that the switch processes authentication link-security
failures resulting from unrecognized user credentials by authorizing a
restricted VLAN on the port after a failed authentication attempt.
Step 7 authentication host-mode
multi-domain Configure authentication manager mode on the port to allow both a host
and a voice device to be authenticated on the 802.1x-authorized port. If
not configured, the default host mode is single.
Step 8 authentication linksec policy
must-secure Set the LinkSec security policy to secure the session with MACsec if the
peer is available. If not set, the default is
should secure.
Step 9
authentication port-control auto Enable 802.1x authentication on the port. The port changes to the
authorized or unauthorized state based on the authentication exchange
between the switch and the client
Step 10
authentication violation protect Configure the port to drop unexpected incoming MAC addresses when a
new device connects to a port or when a device connects to a port after the
maximum number of devices are connected to that port. If not configured,
the default is to shut down the port.
Step 11 mka policy policy name Apply an existing MKA protocol policy to the interface, and enable MKA
on the interface. If no MKA policy was configured (by entering the
mka
policy global configuration command), you must apply the MKA default
policy to the interface by entering the mka default-policy interface
configuration command.
Step 12 dot1x pae authenticator Configure the port as an 802.1x port access entity (PAE) authenticator.
Step 13
spanning-tree portfast Enable spanning tree Port Fast on the interface in all its associated
VLANs. When Port Fast feature is enabled, the interface changes directly
from a blocking state to a forwarding state without making the
intermediate spanning-tree state changes.
Step 14
end Return to privileged EXEC mode.
Step 15 show authentication session interface
interface-id
Verify the authorized session security status.
Step 16 copy running-config startup-config (Optional) Save your entries in the configuration file.
