MAC Security with Pre-shared Keys
		Authentication Limitations
 
  
	
		The following limitations apply to the MAC Security (MACsec) with Pre-shared
			Keys (PSK) Authentication:
				- This initial release of MACsec only
					implements section point-to-point LANs within a secured network as described in
						Clause 7.4 MACsec to
						support Infrastructure LANs of the much broader standard outlined in
						IEEE802.1X-2010
						Port-Based Access Control. All other sections and clauses are not
						supported.

Note   
MACSec
						between customer edges over L2VPN is supported on untagged access
						ports.
 
 
				- MACsec is only configurable using CLI commands. There is no SNMP access to the
					two MACsec MIBs defined by IEEE: IEEE8021X-PAE-MIB and IEEE8021-SECY-MIB.
 
				- MACsec is not supported on ports with stacking enabled.
 
				- MACsec is not supported on Extended Edge Switching ports.
 
				- Hot swapping LRM/MACsec Adapters is not supported. MACsec must be disabled
					before hot swapping. 
 
				- The LRM/MACsec Adapters cannot be connected across slots on a
					stack.
