Guidelines Here are the guidelines to MAC address-based port security:
 The filtering of a packet occurs on the ingress port, not on the egress
port.
 You cannot use MAC address-based port security and 802.1x port-
based access control on the same port. To configure a port as an
Authenticator or Supplicant in 802.1x port-based access control, you
must remove MAC address-based port security.
 MAC address-based port security is not supported on the optional
GBIC, SFP, or XFP modules.
 You can manually add static addresses to ports that are configured for
this security. The manually added addresses are not counted against
the maximum number of addresses the ports can learn.
