Displays transmitted and dropped (congested) packets for each MACsec engine. Each slot has four engines: two encryption and two decryption.
| macsec-engines | Specifies the display of transmitted and dropped packets for each MACsec engine. | 
| congestion | Specifies the display of packets dropped at ingress due to port congestion. | 
| no-refresh | Specifies a static snapshot of data instead of the default dynamic display. | 
| refresh | Specifies a continuous refresh of output. | 
N/A.
The MACsec engines correspond to the internal MACsec ports and not to any external switch ports.
