Port isolation commands

display port-isolate group

Use display port-isolate group to display port isolation group information.

Syntax

Devices that support only one isolation group:

display port-isolate group

Devices that support multiple isolation groups:

display port-isolate group [ group-id ]

Parameters

group-id: Specifies an isolation group by its ID. The value range varies by device model.

Examples

# Display port isolation group information.

<Sysname> display port-isolate group

 Port isolation group information:

 Group ID: 1

 Group members:

    GigabitEthernet1/0/2

 Community VLAN ID: 3

# Display all isolation groups.

<Sysname> display port-isolate group

 Port isolation group information:

 Group ID: 1

 Group members:

    GigabitEthernet1/0/1

 

 Group ID: 5

 Group members:

    GigabitEthernet1/0/2            GigabitEthernet1/0/4

 Community VLAN ID: 3

# 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: 1(default), 2

Table 1 Command output

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.
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.

Use undo port-isolate enable to remove a port from an isolation group.

Syntax

port-isolate enable

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.

You cannot assign the member ports of a service loopback group to an isolation group, and vice versa.

This command assigns a port to the default isolation group (isolation group 1). (Applicable to devices that support only one isolation group.)

Examples

# Assign GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 to the default isolation group.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] port-isolate enable

[Sysname-GigabitEthernet1/0/1] quit

[Sysname] interface gigabitethernet 1/0/2

[Sysname-GigabitEthernet1/0/2] 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 1/0/1

[Sysname-GigabitEthernet1/0/1] port link-aggregation group 1

[Sysname-GigabitEthernet1/0/1] quit

[Sysname] interface gigabitethernet 1/0/2

[Sysname-GigabitEthernet1/0/2] port link-aggregation group 1

[Sysname-GigabitEthernet1/0/2] quit

[Sysname] interface bridge-aggregation 1

[Sysname-Bridge-Aggregation1] port-isolate enable
