Port isolation commands
display port-isolate group
Use display port-isolate group to display port isolation group information.
Syntax
display port-isolate group [ group-number ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
group-number: Specifies an isolation group by its number in the range of 1 to 8.
Examples
# Display all isolation groups.
<Sysname> display port-isolate group
Port isolation group information:
Group ID: 2
Group members:
Ten-GigabitEthernet1/0/1
Group ID: 5
Group members:
Ten-GigabitEthernet1/0/2
Ten-GigabitEthernet1/0/4
# Display information about isolation group 2.
<Sysname> display port-isolate group 2
Port isolation group information:
Group ID: 2
Group members:
Ten-GigabitEthernet1/0/1

Related commands
port-isolate enable
port-isolate enable
Use port-isolate enable to assign a port to an isolation group.
Use undo port-isolate enable to remove a port from an isolation group.
Syntax
port-isolate enable group group-number
undo port-isolate enable
Default
The port is not assigned to any isolation group.
Views
Layer 2 Ethernet interface view, Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
group group-number: Specifies an isolation group by its number in the range of 1 to 8.
Usage guidelines
The configuration in Layer 2 Ethernet interface view applies only to the interface.
The configuration in Layer 2 aggregate interface view applies to the Layer 2 aggregate interface and its aggregation member ports. If the device fails to apply the configuration to the aggregate interface, it does not assign any aggregation member port to the isolation group. If the failure occurs on an aggregation member port, the device skips the port and continues to assign other aggregation member ports to the isolation group.
To assign ports to an isolation group, make sure the isolation group already exists.
One port can be assigned to only one isolation group.
Examples
# Assign ports Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 to isolation group 2.
<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] port-isolate enable group 2
[Sysname-Ten-GigabitEthernet1/0/1] quit
[Sysname] interface ten-gigabitethernet 1/0/2
[Sysname-Ten-GigabitEthernet1/0/2] port-isolate enable group 2
