show macsec usage

show macsec usage


Displays a per-port view of MAC Security (MACsec) usage information.

Syntax Description

usage Specifies to display per-port MACsec usage information.



Usage Guidelines

Displays the number of ports that have MACsec enabled, and the maximum number of ports allowed, per slot. 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 information:

# show macsec usage           
	   ----Port Count----  ------Bandwidth-----
Slots     #Enabled     Limit  Allocated    Maximum
========  ========  ========  =========  =========
Slot-1           1        48    1.0Gbps   50.0Gbps     


The following example shows MACsec usage information on ports 1-5:

# show macsec ports 1-5 usage 
               Link  to BW     MACsec   Allocated
Port          Speed  Maximum?  Enabled  Bandwidth
========  =========  ========  =======  =========
1           1.0Gbps  Yes       No               -
2           1.0Gbps  Yes       No               -
3           1.0Gbps  Yes       No               -
4           1.0Gbps  Yes       No               -
5           1.0Gbps  Yes       No               -
