1.1.2 Link Types of Ethernet Ports
An Ethernet port on an S3100-52P switch can operate in one of the three link types:
z
Access: An access port can belong to only one VLAN, and is generally used to
connect user PCs.
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.
