Chapter 1 Configuring MACsec Encryption
Understanding Cisco TrustSec MACsec
This is an example of configuring and verifying MACsec on an interface:
Switch(config)# interface GigabitEthernet1/0/25
Switch(config-if)# switchport access vlan 10
Switch(config-if)# switchport mode access
Switch(config-if)# macsec
Switch(config-if)# authentication event linksec fail action authorize vlan 2
Switch(config-if)# authentication host-mode multi-domain
Switch(config-if)# authentication linksec policy must-secure
Switch(config-if)# authentication port-control auto
Switch(config-if)# authentication violation protect
Switch(config-if)# mka policy replay-policy
Switch(config-if)# dot1x pae authenticator
Switch(config-if)# spanning-tree portfast
Switch(config-if)# end
Switch# show authentication sessions interface gigabitethernet1/0/25

Understanding Cisco TrustSec MACsec
Note Cisco TrustSec MACsec for switch-to-switch security is supported only on switches running the IP base
or IP services feature set. It is not supported on switches running the NPE or LAN base feature set.
Table 1-2 summarizes the Cisco TrustSec features supported on the switch. For more detailed
explanations, see the Cisco TrustSec Switch Configuration Guide:
