Chapter 19 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. 19.1 port isolation Description The port isolation command is used to configure the forward port/LAG list of a port/LAG, so that this port/LAG can only communicate with the ports/LAGs on its list. To delete the corresponding configuration, please use no port isolation command. Syntax port isolation { [ gi-forward-list gi-forward-list ] [ po-forward-list po-forward-list ] } no port isolation Parameter gi-forward-list -- The list of Ethernet ports. po-forward-list -- The list of LAGs. Command Mode Interface Configuration Mode (interface gigabitEthernet / interface range gigabitEthernet / interface port-channel / interface range port-channel) Privilege Requirement Only Admin and Operator level users have access to these commands. Example Set port 1, 2, 4 and LAG 2 to the forward list of port 1/0/5: T1500G-10MPS(config)# interface gigabitEthernet 1/0/5 T1500G-10MPS(config-if)# port isolation gi-forward-list 1/0/1-2,1/0/4 po-forward-list 2 Set all Ethernet ports and LAGs to forward list of port 1/0/2, namely restore to the default setting: T1500G-10MPS(config)# interface gigabitEthernet 1/0/2 T1500G-10MPS(config-if)# no port isolation 165

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.
19.1
port isolation
Description
The
port isolation
command is used to configure the forward port/LAG list of
a port/LAG, so that this port/LAG can only communicate with the ports/LAGs
on its list. To delete the corresponding configuration, please use
no
port
isolation
command.
Syntax
port
isolation
{
[
gi-forward-list
gi-forward-list
]
[
po-forward-list
po-forward-list
] }
no port isolation
Parameter
gi-forward-list
—— The list of Ethernet ports.
po
-forward-list
—— The list of LAGs.
Command Mode
Interface Configuration Mode (interface gigabitEthernet / interface range
gigabitEthernet / interface port-channel / interface range port-channel)
Privilege Requirement
Only Admin and Operator level users have access to these commands.
Example
Set port 1, 2, 4 and LAG 2 to the forward list of port 1/0/5:
T1500G-10MPS(config)# interface gigabitEthernet
1/0/5
T1500G-10MPS(config-if)#
port
isolation
gi-forward-list
1/0/1-2,1/0/4
po-forward-list
2
Set all Ethernet ports and LAGs to forward list of port 1/0/2, namely restore to
the default setting:
T1500G-10MPS(config)# interface gigabitEthernet
1/0/2
T1500G-10MPS(config-if)# no port isolation
