Chapter 6 Port Isolation Function Configuration 
6.1 Introduction to Port Isolation Function 
Port  isolation is  an  independent port-based  function working  in  an  inter-port  way,  which 
isolates  flows  of  different  ports  from  each  other.  With  the  help  of  port  isolation,  users  can 
isolate ports within a VLAN to save VLAN resources and enhance network security. After this 
function is configured, the ports in a port isolation group will be isolated from each other, while 
ports belonging to different isolation groups or no such group can forward data to one another 
normally. No more than 16 port isolation groups can a switch have. 
6.2 Task Sequence of Port Isolation 
1.  Create an isolate port group 
2.  Add Ethernet ports into the group 
3.  Display the configuration of port isolation 
1.  Create an isolate port group 
Command 
Explanation 
Global Mode 
isolate-port group <WORD> 
no isolate-port group <WORD> 
Set a port isolation group; the no operation of 
this  command  will  delete  the  port  isolation 
group. 
2.  Add Ethernet ports into the group 
Command 
Explanation 
Global Mode 
isolate-port group <WORD> switchport 
interface [ethernet] <IFNAME> 
no isolate-port group <WORD> switchport 
interface [ethernet] <IFNAME> 
Add  one  port  or  a  group  of  ports into  a  port 
isolation  group  to  isolate,  which  will  become 
isolated from the other ports in the group; the 
no operation of this command will remove one 
port or a group of ports out of a port isolation 
group.
