VLAN of H3C three switch

Ethernet frame of traditional adds 4 bytes HP JD377A of 802.1Q tags, as a VLAN tag afterframe

Vlan id=0 for the identification of priority, VLAN id=4095 as the reserved values

IEEE 802.1Q defines a new field, is used to identify the Ethernet framebelongs to VLAN, the field is added in the etheric

After the network frame of the MAC source, the TPID contains a fixed value:0x8100

Port of port VLAN known as the default VLAN, also known as the default all ports of the PVID default value is vlan1

Allow only the Ethernet frame by default VLAN port called access port, Access port after receiving the Ethernet frame type VLAN label, VLAN label forwardinga port is stripping. Allow multiple VLAN frame through a port called Trunk port

PVID is set in a fixed label port, for some VLAN on the switch does not play tagcan then

The Hybrid port can be used for the interconnection between the switches, can also be used to connect the terminal host or router equipment

Common VLAN division (order matching):

Based on the MAC address of the VLAN, based on IP network VLAN protocolbased on VLAN port based VLAN

Technology of dynamic VLAN configuration of general GVRP (GARP VLANGeneric Attribute Registration Protocol)

GVRP multicast destination MAC address: 01.80.C2.00.00.21

GVRP port registration modes: Normal mode, Fixed mode, Forbidden mode

GARP timer: timer Join timer, Hold, Leave, LeaveAll timer timer

Vlan basic configuration: VLAN XX (to create VLAN), port interface-list (port),

Port based on VLAN XX

Port Ethernet x/x

In view of port link-type trunk interface (port link type trunk)

Port trunk peimit VLAN XX (allows the VLAN through the current trunk port)

When implementing the undo VLAN command to delete the VLAN is the defaultVLAN port, Access port for the default VLAN back to VLAN 1, the Trunk and Tybrid ports, the port will not change the default vlan.

The VLAN function can only be MAC address configuration in port based onHybrid

Mac-vlan mac-address xxxx-xxxx-xxxx VLAN XX (VLAN and priority of the corresponding MAC address configured)

Interface port link-type hybrid views

Port hybrid VLAN XX XX untagged (allows you to specify the VLAN through theHybrid port)

Mac-vlan enable (open port MAC VLAN function)

The basic configuration of GVRP

[Switch]gvrp (open global GVRP function) [Switch-ethernet1/1] GVRP (portGVRP)

Must first open the global GVRP function, can open the port function of GVRP(must be trunk port)

Configure the GVRP timer

[Switch]grap timer leaveall (default 1000 seconds)

[Switch-ethernet1/1] GVRP timer {hold 10 |join HP JG241A  20 |leave per second persecond 60 seconds}
