MAC Security Feature License

Use of the MAC Security (MACsec) feature requires a slot-based MACsec Feature License.

Slot-based MACsec licenses have the following behaviors:

Table 1. MACsec License Behavior
	No License	License Installed
Standalone Switch	The command show macsec is the only available command. MACsec cannot be configured or enabled.	All MACsec commands are available. MACsec can be configured and enabled.
Stack	All MACsec commands are available. MACsec can be configured on MACsec-capable slots. If configured, MACsec cannot be enabled.	All MACsec commands are available. MACsec can be configured and enabled on licensed slots.

Note

In a stack, any slot configured with a MACsec-capable module (with configure slot slot module module_type) can be configured for MACsec, even if the slot is not physically present, or if the slot is present, but does not have a valid MACsec license installed.
