8.3 Port Isolation Function Typical Examples
Figure 8-1 A 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:
