Cisco ACI-SEC-XF, DCN Security Licence for Nexus 9K Fixed, CloudSec

ACI-SEC-XF is the Cisco DCN security licence for fixed Nexus 9K switches, sold as an add-on. Cisco's licensing guide says the security add-on enables MACsec and Secure VXLAN EVPN Multi-Site using CloudSec, and that ACI-SEC-XF replaces the older NXOS-SEC-XF. It can be added to either the Essentials or the Advantage tier. Security and network teams in Dubai and across the UAE can request a quotation by part number. CloudSec support depends on the switch platform and release, so check both first.
