Operating mechanism for device-oriented mode
As shown in
negotiation.
In this mode, the session negotiation, secure communication, and session termination processes are
the same as the processes in client-oriented mode. However, MACsec performs a key server
selection in this mode. The port with higher MKA key server priority becomes the key server, which is
responsible for the generation and distribution of SAKs.

Protocols and standards

•
IEEE 802.1X-2010, Port-Based Network Access Control
•
IEEE 802.1X-2006, Media Access Control (MAC) Security

Feature and hardware compatibility

MACsec is supported on all the ports on the LSQM2GP44TSSE0(JH431A) module.

General restrictions and guidelines

When you configure MACsec, follow these restrictions and guidelines:
•
In device-oriented mode, the MACsec configuration takes effect on Layer 2 and Layer 3
Ethernet ports.
•
MACsec is not supported on an aggregate interface, but it is supported on the member ports of
an aggregation group.
•
The MACsec header occupies 38 bytes in each frame. Please take into consideration the
header when you plan the network capacity.
