Configure protocol-based VLAN entry, the frame type is Ethernet II, ethernet type is 0x900.

Add VID=5 tag to untagged packets ingress from port 4

QTECH(config)# vlan-protocol table index 0 ethertype 900 protocol

ethernetv2

QTECH(config)#interface ethernet 0/0/4

QTECH(config-if-ethernet-0/0/4)#vlan-protocol table index 0 vlan 5

QTECH(config-if-ethernet-0/0/4)#vlan-protocol

3.8.3 VLAN translate

VLAN translate can be divided into ingress and egress part.

 Configure VLAN translate:

Configure it in global configuration mode

vlan-translate { ingress | egress } table <startvid> <endvid> <new vid>

no vlan-translate { ingress | egress } table [<startvid> <endvid>]

 Enable VLAN translate:

Configure it in interface configuration mode

[no] vlan-translate { ingress | egress }

For example:

!Translate packet which ingress from port 4 VID 5 to be 8

QTECH(config)#vlan-translate ingress table 5 5 8

QTECH(config)#interface ethernet 0/0/4

QTECH(config-if-ethernet-0/0/4)#vlan-translate ingress

3.8.4 N:1 VLAN

N:1 VLAN is used for: user A, B and C uses VLAN A, B and C. But uplink server uses VLAN D.

So uplink data should translate VLAN A,B,C to be VLAN D; downlink data should translate

VLAN D to be VLAN A,B,C.

Uplink data translate uses vlan-translate egress; downlink data translate can:

1. static configuration: use acl to do VLAN translate according to user's mac and ip;

2. dynamic configuration: enable N:1VLAN of DHCP SNOOPING to get VLAN auto-match;

For example:

!Configure QinQ global TPID to be 0x88a8

QTECH(config)dtag outer-tpid 88A8
