1.1.2 Link Types of Ethernet Ports
An Ethernet port on an S3600 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.
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/trun k port can belong to
several VLANs, and so a default VLAN ID for the port is required.
After you configure default VLAN IDs for Ethernet ports, the packets passing through
the ports are processed in different ways depending on different situations. See
1-2 for details.

z If the VLAN ID is just

z If the VLAN ID is not

but is one of the
VLAN IDs allowed to

port, receive the
packet.
z If the VLAN ID is
neither the default
VLAN ID, nor one of
the VLAN IDs
allowed to pass
through the port,
discard the packet.
Processing of an outgoing
packet
Deprive the tag from the packet
and send the packet.
z If the VLAN ID is just the
default VLAN ID, deprive
the tag and send the packet.
z If the VLAN ID is not the
default VLAN ID, keep the
original tag unchanged and
send the packet.
Send the packet if the VLAN ID
is allowed to pass through the
port. Use the port hybrid vlan
command to configure whether
the port tags the packet when
sending a packet in this VLAN
(including default VLAN).
Caution:
You are recommended to set the default VLAN ID of the local hybrid or trunk ports to
the same value as that of the hybrid or trunk ports on the peer switch. Otherwise,
packet forwarding may fail on the ports.
1.1.4 Adding an Ethernet Port to Specified VLANs
You can add the specified Ethernet port to a specified VLAN. After that, the Ethernet
port can forward the packets of the specified VLAN, so that the VLAN on thi s switch can
intercommunicate with the same VLAN on the peer switch.
An access port can only be added to one VLAN, while hybrid and trunk ports can be
added to multiple VLANs.

Note:
The access ports or hybrid ports must be added to an existing VLAN.
