Restrictions: Hardware compatibility with MACsec
MACsec is supported only on the following ports on the HPE FlexFabric 5950 4-slot Switch (JH404A):
The 24 SFP+ ports on the LSWM124XG2Q (JH181A) interface card.
The 24 10GBASE-T ports on the LSWM124XGT2Q (JH182A) interface card.
The 8 QSFP28 ports on the LSWM18CQMSEC (JH957A) interface card.
If interface cards that have MACsec-capable interfaces are enabled with MACsec, the interface cards do not support hot swapping.
You cannot enable MKA on a MACsec-incapable port.
