8.3 Port Isolation Function Typical Examples
Figure 8-1: 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 cannot 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:
