Port Security can be enabled on a per-port basis. When a port is locked, only packets with allowable source MAC addresses
can be forwarded. All other packets are discarded. A MAC address can be defined as allowable by one of two methods:
dynamically or statically. Note that both methods are used concurrently when a port is locked.
Dynamic locking implements a "first arrival" mechanism for Port Security. You specify how many addresses can be learned
on the locked port. If the limit has not been reached, then a packet with an unknown source MAC address is learned and
forwarded normally. Once the limit is reached, no more addresses are learned on the port. Any packets with source MAC
addresses that were not already learned are discarded. Note that you can effectively disable dynamic locking by setting the
number of allowable dynamic entries to zero.
Static locking allows you to specify a list of MAC addresses that are allowed on a port. The behavior of packets is the same
as for dynamic locking: only packets with an allowable source MAC address can be forwarded.
To see the MAC addresses learned on a specific port, see
page 82.
Disabled ports can only be activated from the Configuring Ports page.
The Port Security folder contains links to the following pages:
•

"Port Security Administration"

• "Port Security Interface Configuration"
• "Port Security Static"
• "Port Security Dynamic"
