port isolate-state enable vlan

Function

The port isolate-state enable vlan command configures interface isolation on an interface in a VLAN.

The undo port isolate-state enable vlan command cancels the configuration.

By default, isolation is not configured on interfaces.

Format

port isolate-state enable vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> }

port isolate-state enable vlan vlan-id1

undo port isolate-state enable vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> }

undo port isolate-state enable vlan vlan-id1

Parameters

Parameter	Description	Value
vlan-id1	Specifies the start VLAN ID.	The value is an integer ranging from 1 to 4094.
vlan-id2	Specifies the end VLAN ID.	The value is an integer ranging from 1 to 4094. vlan-id2 must be greater than vlan-id1.

Usage Guidelines

Usage Scenario

Before configuring isolation on an interface, add the interface to a VLAN.

The port isolate-state enable command isolates two or more interfaces in a VLAN. Therefore, run this command on two or more interfaces in the VLAN. Otherwise, the interface isolation function does not take effect.

To run the port isolate-state enable vlan command on a Layer 3 interface, first switch the interface to a Layer 2 interface using the portswitch command.

Example

# Configure interface isolation on GE 0/1/0 in VLAN 10.

<HUAWEI> system-view
[~HUAWEI] vlan 10
[*HUAWEI-vlan10] interface GigabitEthernet0/1/0
[*HUAWEI-GigabitEthernet0/1/0] portswitch
[*HUAWEI-GigabitEthernet0/1/0] port default vlan 10
[*HUAWEI-GigabitEthernet0/1/0] port isolate-state enable vlan 10
