8.4 Port isolation

8.4.1 Brief introduction of port isolation

Forbid intercommunication of users in different interfaces by port isolation configuration.

There are two kinds of interfaces in port isolation function. One is uplink port, and the other is

downlink port. Uplink port can transmit any packet, but downlink port can only transmit the

packet whose destination is uplink port. Connect user’s computer to downlink port, and

advanced devices connect to uplink port to shield intercommunication bwtween users and not

influence user accessing exterior network through advanced switching devices.

8.4.2 Port isolation configuration

Use port-isolation command in global configuration mode to add a or a group of descendent

isolation port. Use no port-isolation command to remove a or a group of descendent isolation

port:

 Add port isolation downlink port

port-isolation { interface-list }

 Delete port isolation downlink port

no port-isolation { interface-list | all }

interface-list is the optioned interface list which means one or more Ethernet interfaces. When

adding port isolation downlink ports, not all ports can be added to be port isolation downlink

ports. Choose all only when delete port isolation downlink ports. Choose «all» to remove all

downlink isolation ports. By default, all ports are port isolation uplink ports.

For example:
