z Trunk: A trunk port can belong to more than one VLAN. It can receive/send
packets from/to multiple VLANs, and is generally used to connect another switch.
z Hybrid: A hybrid port can belong to more than one VLAN. It can receive/send
packets from/to multiple VLANs, and can be used to connect either a switch or
user PCs.
 Note:
A hybrid port allows the packets of multiple VLANs to be sent without tags, but a trunk
port only allows the packets of the default VLAN to be sent without tags.
You can configure all the three types of ports on the same device. However, note that
you cannot directly switch a port between trunk and hybrid and you must set the port as
access before the switching. For example, to change a trunk port to hybrid, you must
first set it as access and then hybrid.
1.1.3 Configuring the Default VLAN ID for an Ethernet Port
An access port can belong to only one VLAN. Therefore, the VLAN an access port
belongs to is also the default VLAN of the access port. A hybrid/trunk port can belong to
several VLANs, and so a default VLAN ID for the port is required.
z After you configure default VLAN IDs for Ethernet ports, the packets passing
through the ports are processed in different ways depending on different
situations:
