9.4 Port isolation

9.4.1 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.

9.4.2 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:

! Add Ethernet 0/1, Ethernet 0/3, Ethernet 0/4, Ethernet 0/5, Ethernet 0/8 to be downlink isolation port.

QTECH(config)#port-isolation ethernet 0/1 ethernet 0/3 to ethernet 0/5 ethernet 0/8

! Remove ethernet 0/3, Ethernet 0/4, Ethernet 0/5, ethernet 0/8 from downlink isolation port.

QTECH(config)#no port-isolation ethernet 0/3 to ethernet 0/5 ethernet 0/8
