Ethernet Port
Configuration Example
Networking Requirements
Switch A is connected to Switch B through Trunk port Ethernet1/0/1. Configure the
trunk port with a default VLAN ID, so that:
When receiving packets without a VLAN Tag, the port can forward them to the
member ports belonging to the default VLAN
When it is sending the packets with VLAN Tag and the packet VLAN ID is the
default VLAN ID, the trunk port will remove the packet VLAN Tag and forward the
packet.
