show macsec ports usage

show macsec ports port-list usage


Displays per-port MAC Security (MACsec) usage data in tabular format.

Syntax Description

ports Specifies ports to show information on.
port_list Lists which ports to view MACsec information on.
usage Specifies to display per-port MACsec usage information.



Usage Guidelines

Displays per-port MACsec usage information. This command also displays the amount of bandwidth consumed by the enabled ports (assumes maximum throughput), as well as the maximum bandwidth allowed.

If the switch type has no port limit, then the "Port Count Limit" is displayed as N/A. If the switch has no bandwidth limit, then the "Bandwidth Maximum" is also displayed as N/A.



The CLI prevents you from exceeding the port limit but not the bandwidth limit. If the instantaneous traffic across all MACsec-enabled ports exceeds the switch's bandwidth limit, then excess traffic will be dropped.


The following example shows MACsec usage on ports 1-2 and 49-56:
