Chapter 15 Port Isolation Commands
Port Isolation provides a method of restricting traffic flow to improve the network security by
forbidding the port to forward packets to the ports that are not on its forwarding port list.
port isolation
Description
The
port isolation
command is used to configure the forward port list of a port,
so that this port can only communicate with the ports on its port list. To delete
the corresponding configuration, please use
no
port isolation
command.
Syntax
port isolation
{ [
fa-forward-list
fa-forward-list
] [
gi-forward-list
gi-forward-list
] }
no port isolation
Parameter
fa-forward-list
——Configure Fast Ethernet ports to the forward port list.
gi-forward-list
—— Configure Gigabit Ethernet ports to the forward port list.
Command Mode
Interface Configuration Mode (interface fastEthernet / interface range
fastEthernet / interface gigabitEthernet / interface range gigabitEthernet)
Example
Set port 1, 2, and 4 to the forward port list of port 5:
T1500-28PCT(config)# interface fastEthernet
1/0/5
T1500-28PCT(config-if)# port isolation
fa-forward-list
1/0/1-2,1/0/4
Set all Ethernet ports to forward port list of port 2, namely restore to the default
setting:
T1500-28PCT(config)# interface fastEthernet
1/0/2
T1500-28PCT(config-if)# no port isolation
show port isolation interface
Description
The
show port isolation
interface
command is used to display the forward port
list of a port.
