Using Passwords, Port
Security, and Authorized IP
Figure 7-3. Example of How Port Security Controls Access
Note Broadcast and Multicast traffic is not “unauthorized” traffic, and can be read
by intruders connected to a port on which you have configured port security.
Trunk Group Exclusion
Port security does not operate on either a static or dynamic trunk group. If
you configure port security on one or more ports that are later added to a trunk
group, the switch will reset the port security parameters for those ports to the
factory-default configuration. (Ports configured for either Active or Passive
LACP, and which are not members of a trunk, can be configured for port
security.)
