6.3 Port Isolation Function Typical Examples 
Typical example of port isolation function 
The topology and configuration of switches are showed in the figure above, with e1/1, e1/10 
and e1/15 all belonging to VLAN 100. The requirement is that, after port isolation is enabled on 
switch S1, e1/1 and e1/10 on switch S1 can not communicate with each other, while both of 
them can communicate with the uplink port e1/15. That is, the communication between any 
pair of downlink ports is disabled while that between any downlink port and a specified uplink 
port is normal. The uplink port can communicate with any port normally. 
The configuration of S1:
