Media Access Control Security (MACsec) is an industry standard encryption mechanism that protects all traffic flowing on the Ethernet links. MACsec is based on IEEE 802.1X and IEEE 802.1AE standards. By default, if MACsec configuration is applied on the interface, then it encrypts and decrypts all the other protocols PDU and other data packets. This document talks about a feature which allows LLDP protocol packets to bypass encryption and decryption. Additionally, from release 4.26.0F, there is a way to allow LLDP packets to be sent/received from the port even when the port is not authorized i.e. even when MKA session is yet to become successful.

The MACsec scheduler compensation feature is used to automatically make adjustments to the packet size seen by the scheduler for MACsec encrypted traffic, based on MACsec configuration.
