3.6.7 Display vlan that can be learnt by GVRP

Use show garp permit vlan command to display current static vlan permitted learning by GVRP

show garp permit vlan

For example:

Display current static vlan permitted learning by GVRP

QTECH(config)#show garp permit vlan

3.6.8 Examples for GVRP configuration

! Enable GVRP on Ethernet port 2

QTECH(config-if-ethernet-0/0/2)#gvrp

! Disable GVRP on Ethernet port 2

QTECH(config-if-ethernet-0/0/2)#no gvrp

3.7 QinQ configuration

3.7.1 Brief introduction of QinQ

QinQ is used for the commnunication between discrete client vlan whose service model is the

interconnection of one or more switches supported QinQ by service provider interfaces which

are in service provider vlan. The interface linking client vlan is called customer interface.

Packet with client vlan tag will add a tag head with the vlan id being service provider vlan when

passing through the customer interface. The tag head will be stripped when passing through

service provider vlan.

3.7.2 QinQ configuration list

 Configure global QinQ

 Configure interface QinQ

3.7.3 Configure global QinQ

QTECH QSW-3200-24TC can only support static QinQ:

1, static 802.1q in 802.1q. Vlan protocol number in this mode can be configured but can only

be 0x8100 or 0x88a8 and there will be a new tag inserted between the 12th and 13th bit;

!Use dtag command to enable/disable QinQ globally in global configuration mode.

dtag { [ flexible-qinq ] | outer-tpid tpid }

no dtag

For example:

!Configure QinQ global TPID to be 0x88a8

QTECH(config)dtag outer-tpid 88A8

3.7.4 Configure QinQ mode of interface

There are two kinds of interface modes: one is service provider port, the other is customer

port. The former do not permit ignoring tag head of ingress packet and the latter permits.

! It is in the interface configuration mode.

dtag mode { customer | service-provider }

Example:

Configure interface to be customer
