40 CHAPTER 2: PORT CONFIGURATION
Perform the following configuration in Ethernet port view.
The access port will be added to an existing VLAN other than VLAN 1. The VLAN
to which a Hybrid port is added must exist. The VLAN to which a Trunk port is
added cannot be VLAN 1.
After adding the Ethernet port to the specified VLANs, the local port can forward
packets from these VLANs. The hybrid and trunk ports can be added to multiple
VLANs, thereby, implementing the VLAN intercommunication between peers. For
the hybrid port, you can tag VLAN packets to process packets in different ways,
depending on the target device.
Setting the Default VLAN ID for Ethernet Port
Since the access port can only be included in one VLAN, its default VLAN is the
one to which it belongs. The hybrid port and the trunk port can be included in
several VLANs, however, it is necessary to configure the default VLAN ID. If the
default VLAN ID has been configured, the packets without VLAN Tag will be
forwarded to the port that belongs to the default VLAN. When sending the
packets with VLAN Tag, if the VLAN ID of the packet is identical to the default
VLAN ID of the port, the system will remove VLAN Tag before sending this packet.
Perform the following configuration in Ethernet port view.
■ A Trunk port and isolate-user-vlan cannot be configured simultaneously. A
hybrid port and isolate-user-vlan can be configured simultaneously. However, if
the default VLAN has been mapped in isolate-user-vlan, you cannot modify the
default VLAN ID until the mapping relationship has been removed.
