-
The N9K-X9400-8D LEM offers full MACsec (64 ports) for a full load chassis but with a limit of 400G high power optics within 32pcs among 8 slots (maximum of 32 ports of 20-W optics irrespective of MACsec), and the high power optics can go in any of the 400G ports.
-
The N9K-X9400-22L LEM offers 22 front ports supporting 10G or 25G or 50G with MACsec.
