To convert a Trunk port into a Hybrid port (or vice versa), you need to use the Access port as a
medium. For example, the Trunk port has to be configured as an Access port first and then a Hybrid
port.
The default VLAN IDs of the Trunk ports on the local and peer devices must be the same.
Otherwise, packets cannot be transmitted properly.
