Port isolation commands

community-vlan vlan

Use community-vlan vlan to configure community VLANs in an isolation group.

Use undo community-vlan to restore the default.

Syntax

community-vlan vlan { vlan-id-list | all }

undo community-vlan

Default

An isolation group does not have any community VLANs.

Views

Isolation group view

Predefined user roles

network-admin

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each item specifies a VLAN ID or a range of VLAN IDs in the format of vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The ID for vlan-id2 must be equal to or greater than the ID for vlan-id1.

all: Specifies all VLANs in the isolation group.

Usage guidelines

To modify the community VLANs for an isolation group, execute the undo community-vlan vlan command to remove the existing community VLANs, and then execute the community-vlan vlan command.

Examples

# Configure VLAN 3 as a community VLAN in isolation group 1.

<Sysname> system-view

[Sysname] port-isolate group 1

[Sysname-port-isolate-group1] community-vlan vlan 3

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:

    Ten-GigabitEthernet1/0/1

 Community VLAN ID: None

 

 Group ID: 5

 Group members:

    Ten-GigabitEthernet1/0/2            Ten-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:

    Ten-GigabitEthernet1/0/1

 Community VLAN ID: None

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.

 

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 Ten-GigabitEthernet 1/0/1 and Ten-GigabitEthernet 1/0/2 to isolation group 1.

<Sysname> system-view

[Sysname] interface ten-gigabitethernet 1/0/1

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

[Sysname-Ten-GigabitEthernet1/0/1] quit

[Sysname] interface ten-gigabitethernet 1/0/2

[Sysname-Ten-GigabitEthernet1/0/2] port-isolate enable group 1

Related commands

display port-isolate group

port-isolate group

Use port-isolate group to create an isolation group.

Use undo port-isolate group to delete isolation groups.

Syntax

port-isolate group group-id

undo port-isolate group { group-id | all }

Default

No isolation groups exist.

Views

Parameters

group-id: Specifies an isolation group by its ID.  The value range is 1 to 8.

all: Deletes all isolation groups.

Examples
