6.4 Ethernet Port Configuration Example
I. Network requirements
Switch A is connected to Switch B through Trunk port GigabitEthernet2/1/1. Configure
the Trunk port with default VLAN ID, so that: when receiving the packets without VLAN
Tag, the port can forward them to the member ports belonging to the default VLAN;
when it sending the packets with VLAN Tag and the packet VLAN ID is the default
VLAN ID, the Trunk port remove the packet VLAN Tag and forward the packet.
