Port isolation commands
display port-isolate group
Use display port-isolate group to display port isolation group information.
Syntax
display port-isolate group [ group-id ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
group-id: Specifies an isolation group by its ID. The value range is 1 to 8.
Examples
# Display all isolation groups.
<Sysname> display port-isolate group
Port isolation group information:
Group ID: 1
Group members:
GigabitEthernet1/0/1
Community VLAN ID: None
Group ID: 5
Group members:
GigabitEthernet1/0/2 GigabitEthernet1/0/4
Community VLAN ID: None
# Display information about isolation group 1.
<Sysname> display port-isolate group 1
Port isolation group information:
Group ID: 1
Group members:
GigabitEthernet1/0/1
Community VLAN ID: None

Field |
Description |
|
Group ID |
ID of the isolation group. The (peer-link) tag indicates that the isolation group is automatically associated with a peer-link interface. |
|
Group members |
Isolated ports in the isolation group. No ports indicates that the isolation group does not contain isolated ports. |
|
Community VLAN ID |
IDs of the community VLANs in the isolation group. The (default) attribute indicates that the VLAN is the default VLAN. None indicates that the isolation group does not contain community VLANs. |
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-id
undo port-isolate enable
Default
The port is not assigned to an isolation group.
Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view
Predefined user roles
network-admin
Parameters
group group-id: Specifies an isolation group by its ID. The value range is 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 GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to isolation group 1.
<Sysname> system-view
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] port-isolate enable group 1
[Sysname-GigabitEthernet1/0/1] quit
[Sysname] interface gigabitethernet 1/0/2
[Sysname-GigabitEthernet1/0/2] port-isolate enable group 1
