Port Isolation

The port isolation is a port-based virtual LAN feature. It partitions the switching ports
into virtual private domains designated on a per port basis. Data switching outside of the
port's private domain is not allowed. It will ignore the packets' tag VLAN information.
This feature is a per port setting to configure the egress port(s) for the specific port to
forward its received packets. If the CPU port (port 0) is not an egress port for a specific
port, the host connected to the specific port cannot manage the Switch.
If you wish to allow two subscriber ports to talk to each other, you must define the egress
port for both ports. CPU refers to the Switch management port. By default it forms a
VLAN with all Ethernet ports. If it does not form a VLAN with a particular port then the
Switch cannot be managed from that port.

Node Command
enable show port-isolation
interface port-isolation ports
PORTLISTS
interface no port-isolation
Example: If you want to allow port-1 and port-3 to talk to each other, you must configure
as below:
L2SWITCH(config)#interface 1/0/1
L2SWITCH(config-if)#port-isolation ports 3
L2SWITCH(config-if)#exit
Allow the port-1 to send its ingress packets to port-3.
L2SWITCH(config)#interface 1/0/3
L2SWITCH(config-if)#port-isolation ports 1
L2SWITCH(config-if)#exit
Allow the port-3 to send its ingress packets to port-1

CLI Configuration

This command displays the current port isolation
configurations.
"V" indicates the port's packets can be sent to
that port.
"-" indicates the port's packets cannot be sent to
that port.
This command configures a port or a range of
ports to egress traffic from the specific port.
This command configures all ports to egress
traffic from the specific port.
