The difference between Hybrid and Access, and set the Huawei Trunk

There are three kinds GICK  of link type Ethernet port: Access, Hybrid and Trunk:

The three type of the link connecting the terminal difference:

Access type of port can only belong to 1 VLAN, typically used to connect the computer port;

Type Trunk port allows multiple VLAN, can message receiving and transmittingmultiple VLAN, generally used for connecting ports between switches;

Type Hybrid port allows multiple VLAN, can message receiving and transmitting multiple VLAN connections, can be used to switch between, can also be used to connect the user's computer.

Treatment processes of the three kinds of link data type is also different:

Acess port message:

Receive a message, to judge whether there is VLAN information: if not, a PVID port forwarding, and exchange, if there is discarded directly (default)

The Acess port to send message:

The VLAN information release message, sent directly.

Trunk port message:

Receive a message, to judge whether there is VLAN information: if not a port of the PVID, and exchange forwarding, if the trunk port whether to allow the VLAN data into: if the forwarding, or discarded

The trunk port to send message:

Comparison of PVID port and will be sending message VLAN information, if it is equal, stripping VLAN information, send, if not equal to directly transmit

Hybrid port message:

Receive a message, to judge whether there is VLAN information: if not a port of the PVID, and exchange forward, if it is determined that the hybrid port is to allow the VLAN data into: if the forwarding, or discarded (at ports on the untag configuration is not considered, only the untag configuration effect of packet transmission)

The hybrid port to send message:

1, whether the VLAN properties in the port (disp interface can see the port isuntag, on which VLAN is what VLAN tag)

2, if untag is the stripping VLAN information, send, if tag is directly send

Generally speaking, Hybrid port and the Trunk port when receiving data,processing method is the same, the only difference is that the data is sent:send Hybrid port allows multiple VLAN message without a label, and the Trunkport is only allowed to send the default VLAN message without a label.

The following a few simple example to understand the configuration and working principle of Trunk, Hybrid, Access.  EPBC
