# Display port isolation group information.
<Sysname> display port-isolate group
Port isolation group information:
Group ID: 1
Group members:
GigabitEthernet0/0/2

Field |
Description |
|
Group ID |
ID of the isolation group. |
|
Group members |
Isolated ports in the isolation group. No ports indicates that the isolation group does not contain isolated ports. |

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

undo port-isolate enable
Default
The port is not assigned to an isolation group.

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.
This command assigns a port to the default isolation group (isolation group 1).
Examples
# Assign GigabitEthernet 0/0/1 and GigabitEthernet 0/0/2 to the default isolation group.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/0/1
[Sysname-GigabitEthernet0/0/1] port-isolate enable
[Sysname-GigabitEthernet0/0/1] quit
[Sysname] interface gigabitethernet 0/0/2
[Sysname-GigabitEthernet0/0/2] port-isolate enable
# Assign Layer 2 aggregate interface Bridge-Aggregation 1 to the default isolation group.
<Sysname> system-view
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] quit
[Sysname] interface gigabitethernet 0/0/1
[Sysname-GigabitEthernet0/0/1] port link-aggregation group 1
[Sysname-GigabitEthernet0/0/1] quit
[Sysname] interface gigabitethernet 0/0/2
[Sysname-GigabitEthernet0/0/2] port link-aggregation group 1
[Sysname-GigabitEthernet0/0/2] quit
[Sysname] interface bridge-aggregation 1
[Sysname-Bridge-Aggregation1] port-isolate enable
