Chapter 30: MAC Address-based Port Security
354 Section VIII: Port Security
Guidelines
The following guidelines apply 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 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 set its MAC address security level to Automatic, which is the
default setting.
This type of port security is not supported on optional GBIC, SFP, or
XFP modules.
All of a port’s static MAC addresses are deleted when its security level
is changed from Locked to any of the other three security levels.
