3.4.8 Display VLAN information

VLAN information is VLAN description string, vlan-id, VLAN status and interface members in it,

tagged interfaces, untagged interfaces and dynamic tagged interfaces. Interface members

consist of tagged and untagged members.

show vlan [ vlan-id ]

If the VLAN with specified keyword exists, this command displays the information of the

specified VLAN. If no keyword is specified, this command displays the list of all the existing

VLANs

For example:

! Display the information of existed VLAN 2.

QTECH(config)#show vlan 2

3.5 PVLAN

PVLAN means private VLAN which is used to realize interface isolation function. These private

VLANs are unknown to uplink devices to save the resource of public VLAN. Nowadays,

factories in this field use SVL to realize PVLAN and provide corresponding configuration

command. But there is some shortage by using SVL, such as: the uplink and downlink

interfaces are access, and MAC address wasting. Our company uses redirection technology to

realize PVLAN and overcome the shortage of SVL, any interface can be access or trunk,

which entirely realize PVLAN. The detailed information of PVLAN configuration can refer to

interface isolation configuration.

3.6 GVRP configuration

3.6.1 Brief introduction of GVRP

GVRP, GARP VLAN Registration Protocol is a kind of application of GARP. It is based on

GARP working mechanism to maintain VLAN dynamic register information in switch and

transfer it to other switch. All switch that support GVRP can receive VLAN register information

from other switches and dynamically upgrade local VLAN register information which includes:

current VLAN members, and by which interface can reach VLAN members. And all switches

supported GVRP can transfer local VLAN register information to other switches to make the

consistency of the VLAN information of devices which support GVRP. VLAN register

information transferred by GVRP includes local munal configuration of static register

information and the dynamic register information of other switch.

3.6.2 GVRP Configuration list

In all configurations, enable global GVRP first before enable GVRP on a port. GVRP must be

enabled in the two ends of trunk link which follows IEEE 802.1Q standard.

GVRP Configuration list is as following:

 Enable/disable global GVRP

 Enable/disable GVRP on a port

 Display GVRP

 Add/delete vlan that can be dynamic learnt by GVRP

 Display vlan that can be learnt by GVRP
