OmniSwitch AOS Release 6 Network Configuration Guide

Learned Port Security (LPS) provides a mechanism for controlling network device access on one or more 
switch ports. Configurable LPS parameters allow the user to restrict the source learning of host MAC 
addresses to:

• A specific amount of time in which the switch allows source learning to occur on all LPS ports. 

• A maximum number of learned MAC addresses allowed on the port. 

• A list of configured authorized source MAC addresses allowed on the port.

Additional LPS functionality allows the user to specify how the LPS port handles unauthorized traffic. The 
following two options are available for this purpose:

• Block only traffic that violates LPS port restrictions; authorized traffic is forwarded on the port.

• Disable the LPS port when unauthorized traffic is received; all traffic is stopped and a port reset is 

required to return the port to normal operation.

LPS functionality is supported on the following Ethernet and Gigabit Ethernet port types:

• Fixed (non-mobile)

• Mobile

• 802.1Q tagged

• Authenticated

• 802.1x

The following port types are not supported:

• Link aggregate

• Tagged (trunked) link aggregate
