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 e1/0/1, e1/0/10 and e1/0/15

all belonging to VLAN 100. The requirement is that, after port isolation is enabled on switch S1, e1/0/1 and

e1/0/10 on switch S1 can not communicate with each other, while both of them can communicate with the

uplink port e1/0/15. 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

e1/0/1
