Syntax

vlan {vlan-range}

no vlan {vlan-range}

• vlan-range—A list of VLAN IDs to be added. List separate, non-consecutive VLAN IDs separated by commas without spaces. A hyphen designates a range of IDs.

The maximum number of VLANs is 4095.

Example

The following example creates VLAN number 1972.

interface vlan

Use the interface vlan global configuration command to enter the interface configuration (VLAN) mode to configure an existing VLAN.

Syntax

interface vlan vlan-id

• vlan-id—The ID of an existing VLAN (excluding GVRP dynamic VLANs).
  
  

Default Configuration

This command has no default configuration.

Command Mode

Global Configuration Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example configures the VLAN 1 IP address of 10.1.2.3 and subnet mask 255.0.0.0.

User Guidelines

Commands under the interface range context are executed independently on each interface in the range. If the command returns an error on one of the interfaces, an error message is displayed and execution continues on other interfaces.

Example

The following example groups VLAN 221-228 and VLAN 889 to receive the same command.

Console (config)# interface range vlan 221-228, 889 Console (config-if)#

User Guidelines

The VLAN name should be unique.

Example

The following example names VLAN interface 19 as Marketing.

Console (config)# interface vlan 19 Console (config-if)# name Marketing

switchport mode

Use the switchport mode interface configuration command to configure a port VLAN membership mode. To reset the mode to the appropriate default for the port, use the no form of this command.

Syntax

switchport mode { access | trunk | general }

no switchport mode

• access—Port belongs to a single, untagged VLAN.
  
  
• trunk—Port belongs to 1...n VLANs, all tagged (except, optionally, for a single native VLAN).
  
  
• general—Port belongs to 1...n VLANs, and each VLAN is explicitly set by the user as tagged or untagged (full 802.1Q mode).
  
  

Default Configuration

All ports are in access mode and belong to the default VLAN (whose VID=1).

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example configures port 1/e8 as an untagged layer 2 VLAN interface.

Console (config)# interface ethernet 1/e8 Console (config-if)# switchport mode access

switchport access vlan

The switchport access vlan interface configuration command configures the VLAN ID when the interface is in access mode. To reconfigure the default, use the no form of this command.

Syntax

switchport access vlan vlan-id

no switchport access vlan

• vlan-id—VLAN ID to which the port is configured.
  
  

Default Configuration

The default VLAN ID is 1.

User Guidelines

The command automatically removes the port from the previous VLAN, and adds it to the new VLAN.

Example

The following example configures a VLAN ID of 23 to the untagged layer 2 VLAN interface number 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# switchport mode access console (config-if)# switchport access vlan 23

switchport trunk allowed vlan

Use the switchport trunk allowed vlan interface configuration command to add or remove VLANs from a trunk port.

switchport trunk allowed vlan {add vlan-list | remove vlan-list}

• add vlan-list—List of VLAN IDs to add. Separate non-consecutive VLAN IDs with a comma and no spaces. A hyphen designates a range of IDs.
  
  
• remove vlan-list—List of VLAN IDs to remove. Separate non-consecutive VLAN IDs with a comma and no spaces. A hyphen designates a range of IDs.
  
  

Default Configuration

This command has no default configuration.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example adds VLANs to the allowed list of port 1/e8.

Console (config)# interface ethernet 1/e8 Console (config-if)# switchport mode trunk Console (config-if)# switchport trunk allowed vlan add 1,2,5-8

switchport trunk native vlan

Use the switchport trunk native vlan interface configuration command to define the port as a member of the specified VLAN, and the VLAN ID as the port default VLAN ID (PVID). To configure the default VLANID, use the no form of this command.

Syntax

switchport trunk native vlan vlan-id

no switchport trunk native vlan

• vlan-id—A VLAN ID for the active VLAN.
  
  

Default Configuration

The default VLAN ID is 1.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

Incoming untagged frames are assigned to this VLAN and outgoing traffic from this VLAN is sent untagged (despite the normal situation where traffic sent from a trunk-mode port is all tagged).

The port is added as a member in the VLAN. If the port is already a member in the VLAN (not as a native), it should be removed from the VLAN first.

Example

The following example defines port 1/e8, in trunk mode, and is configured to use VLAN number 123 as the native VLAN.

console (config)# interface ethernet 1/e8 Console (config-if)# switchport mode trunk console (config-if)# switchport trunk native vlan 123

switchport general allowed vlan

Use the switchport general allowed vlan interface configuration command to add and remove VLANs from a port in general mode.

Syntax

switchport general allowed vlan add vlan-list [ tagged | untagged ]

switchport general allowed vlan remove vlan-list

• add vlan-list—List of VLAN IDs to add. Separate non-consecutive VLAN IDs with a comma and no spaces. A hyphen designates a range of IDs.
  
  
• remove vlan-list—List of VLAN IDs to remove. Separate non-consecutive VLAN IDs with a comma and no spaces. A hyphen designates a range of IDs.
  
  
• tagged—Sets the port to transmit tagged packets for the VLANs. If the port is added to a VLAN without specifying tagged or untagged, the default is tagged.
  
  
• untagged—Set the port to transmit untagged packets for the VLANs.
  
  

Default Configuration

This command has no default configuration.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example shows how to add VLANs to the allowed list.

console (config)# interface ethernet 1/e8 Console (config-if)# switchport mode general Console (config-if)# switchport general allowed vlan add 1,2,5,6 tagged

switchport general pvid

Use the switchport general pvid interface configuration command to configure the Port VLAN ID (PVID) when the interface is in general mode. To configure the default value, use the no form of this command.

Syntax

switchport general pvid vlan-id

no switchport general pvid

• vlan-id—PVID. The VLAN ID may belong to a non-existent VLAN.
  
  

Default Configuration

The default VLAN ID is 1.

Interface Configuration (Ethernet, port-channel) Mode

User Guidelines

There are no user guidelines for this command.

Example

The following example configures the PVID for port 1/e8, when the interface is in general mode.

no switchport general acceptable-frame-types tagged-only

Default Configuration

All frame types are accepted at ingress.

Command Mode

Interface Configuration (Ethernet, port-channel) Mode
