Port Isolation Function Configuration
4.1 Introduction to Port Isolation Function
Port isolation is an independent port-based function working in an inter-port way, which isolates
flows of different ports from each other. With the help of port isolation, users can isolate ports within
a VLAN to save VLAN resources and enhance network security. After this function is configured,
the ports in a port isolation group will be isolated from each other, while ports belonging to different
isolation groups or no such group can forward data to one another normally. No more than 16 port
isolation groups can a switch have.
4.2 Task Sequence of Port Isolation
1. Create an isolate port group
2. Add Ethernet ports into the group
3. Display the configuration of port isolation
1. Create an isolate port group
Command Explanation
Global Mode
isolate-port group <WORD>
no isolate-port group <WORD>
Set a port isolation group; the no operation of this command
will delete the port isolation group.
2. Add Ethernet ports into the group
Command Explanation
Global Mode
isolate-port group <WORD>
switchport interface [ethernet]
<IFNAME>
no isolate-port group <WORD>
switchport interface [ethernet]
<IFNAME>
Add one port or a group of ports into a port isolation group
to isolate, which will become isolated from the other ports
in the group; the no operation of this command will remove
one port or a group of ports out of a port isolation group.
