3.7. VLAN Classification Commands

Command Purpose

Use this command to apply vlan classifier group to an interface.

To remove it, use the no form of this command.

Prerequisites

Command Syntax

vlan classifier activate GROUP_NUMBER based ( ip | mac | protocol )

no vlan classifier activate

Command Mode

Interface Configuration

Default

None

Usage

An interface can only be applied by one vlan classifier group.

One vlan classifier group can apply more than one interface.

This command applies vlan classifier group to interface, and the interface can classify packets to different vlan according to the rule in vlan classifier group.

To create the rule, refer to vlan classifier rule command.

To create the group, refer to vlan classifier group command.

Examples

This example shows how to apply vlan classifier group 1 to the interface:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# vlan classifier activate 1 based ip

This example shows how to remove the vlan classifier group 1 from the interface:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# no vlan classifier activate

Related Commands

vlan classifier group

vlan classifier rule

Command Purpose

Use this command to add or delete rule to vlan classifier group. Use the no form of this command to delete the group.

Prerequisites

Command Syntax

vlan classifier group GROUP_NUMBER ( add | delete ) rule RULE

no vlan classifier group group

Command Mode

Global Config

Default

None

Usage

To create the rule, refer to vlan classifier rule command.

To apply the vlan classifier group to an interface, refer to vlan classifier activate command.

When add a rule to the group by this command, the rule will be active immediately if the group has been applied to an interface already.

When delete a rule from the group by this command, the rule on this interface will be inactive immediately if the group is still applied to that interface.

The vlan classifier group will be deleted when the last rule on this group is deleted.

Examples

This example shows how to add rule1 to vlan classifier group 1:

Switch# configure terminal
Switch(config)# vlan classifier group 1 add rule 1

This example shows how to delete rule1 from vlan classifier group 1:

Switch# configure terminal
Switch(config)# vlan classifier group 1 delete rule 1

This example shows how to delete vlan classifier group 1:

Switch# configure terminal
Switch(config)# no vlan classifier group 1

Related Commands

vlan classifier activate

vlan classifier rule

Command Purpose

Use this command to create vlan classifier rule.

To remove the vlan classifier rule, use the no form of this command.

Prerequisites

Command Syntax

vlan classifier rule RULE ( ip IP_ADDR | ip IP_ADDR/PREFIX-LENGTH | ipv6 IPV6_ADDR | mac MAC_ADDR | protocol ( arp | ip | mpls | mpls-mcast | pppoe | rarp ) ) vlan VLAN_ID

no vlan classifier rule RULE

Command Mode

Global Config

Default

None

Usage

The rule will be effective only in inbound on interface.

The vlan id assigned by vlan classifier rule will be appended to the packets which match the rule.

To add this rule to vlan classifier group or apply the group to an interface, refer to vlan classifier group and vlan classifier activate command.

Examples

This example shows how to create rule1 which will classify all ipv4 packets to vlan11:

Switch# configure terminal
Switch(config)# vlan classifier rule 1 protocol ip vlan 11

This example shows how to delete rule1:

Switch# configure terminal
Switch(config)# no vlan classifier rule 1

Related Commands

vlan classifier group

vlan classifier activate

Command Purpose

Use this command to set action when not hit vlan classifier rule. Use the no form of this command to restore default action.

Prerequisites

Command Syntax

vlan classifier default-action drop

no vlan classifier default-action drop

Command Mode

Interface Configuration

Default

None

Usage

When packet input the port which enable vlan classifier and not hit any vlan classifier rule, the packet will be dropped.

Examples

This example shows how to set default action drop:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# vlan classifier default-action drop

This example shows how to set default action not drop:

Switch# configure terminal
Switch(config)# interface eth-0-1
Switch(config-if)# no vlan classifier default-action drop
