Chapter 30: MAC Address-based Port Security
354 Section VIII: Port Security
Guidelines
The following guidelines apply to MAC address-based port security:
ˆ The filtering of a packet occurs on the ingress port, not on the egress
port.
ˆ 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.
ˆ This type of port security is not supported on optional GBIC, SFP, or
XFP modules.
ˆ 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.
