Learned Port Security Commands

OmniSwitch CLI Reference Guide

page 18-13

Configures a list of authorized MAC addresses by defining a range of addresses allowed on the port. This 
command also enables LPS on the specified port, if LPS is not already active on the port.

port-security slot/port[-port2] mac-range [low mac_address | high mac_address | low mac_address 
high mac_address]

The slot number for the module and the physical port number on that 
module (e.g., 3/1 specifies port 1 on slot 3).

The last port number in a range of ports you want to configure on the 
same slot (e.g, 3/1-4 specifies ports 1-4 on slot 3).

low mac_address

MAC address that defines the low end of a range of MACs 
(e.g., 00:20:95:00:10:2A).

high mac_address

MAC address that defines the high end of a range of MACs 
(e.g., 00:20:95:00:10:2F).

• If low and high end MAC addresses are not specified with this command, then the range is set back to 

the default range value (00:00:00:00:00:00– ff:ff:ff:ff:ff:ff). 

• Source MAC addresses received on an LPS port that fall within the authorized range are allowed on 

the port. An additional entry is made in the LPS table for each of these learned addresses. 

• Any additional source MAC addresses received that do not match configured authorized addresses are 

allowed on the port based on the LPS time limit (if active) and the maximum number of MAC 
addresses allowed. 

• Each configured authorized MAC address counts towards the number of addresses allowed on the port 

even if the port has not learned the configured address. For example, if a port has 3 configured autho-
rized MAC addresses and the maximum number of addresses allowed is set to 10, then only 7 addi-
tional MAC addresses are allowed on that port.
