2.5.2 Network 

 

 

2.5.2.1 Limit Control 

 

Limit Control allows for limiting the number of users on a given port. A user is identified by a 

MAC address 

and 

VLAN ID

. If Limit Control is enabled on a port, the limit specifies the maximum number of users on the 

port.  If  this  number  is  exceeded,  an  action  is  taken.  The  action  can  be  one  of  the  four  different  actions  as 

described  below.  The  Limit  Control  module  utilizes  a  lower-layer  module,  Port  Security  module,  which 

manages  MAC  addresses  learned  on  the  port.  The  Limit  Control  configuration  consists  of  two  sections,  a 

system- and a port-wide.
