Table 1-3 Processing of incoming/outgoing packets
Port
If the packet
type
does not carry
a VLAN tag
Access
Trunk
Receive the
packet and add
the default tag to
the packet.
Hybrid
To guarantee the proper packet forwarding, the default VLAN ID of the local hybrid port or trunk port
should be identical with that of the hybrid port or trunk port on the peer device.

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 this switch can intercommunicate with the same
VLAN on the peer device.
An access port can only be added to one VLAN, while hybrid and trunk ports can be added to multiple
VLANs.
Note that the port shall be added to an existing VLAN.

Configuring Ethernet Ports

Making Basic Port Configuration

Follow these steps to make basic port configuration:
Processing of an incoming packet
If the packet carries a VLAN tag
If the VLAN ID is just the
default VLAN ID, receive the
packet.
If the VLAN ID is not the
default VLAN ID, discard the
packet.
If the VLAN ID is just the
default VLAN ID, receive the
packet.
If the VLAN ID is not the
default VLAN ID but is one of
the VLAN IDs allowed to pass
through the port, receive the
packet.
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
Deprive the tag from the packet
and send the packet.
1-3
packet
If the VLAN ID is just the
default VLAN ID, deprive the
tag and send the packet.
If the VLAN ID is not the
default VLAN ID, keep the
original tag unchanged and
send the packet.
If the VLAN ID is just the
default VLAN ID, deprive the
tag and send the packet.
If the VLAN ID is not the
default VLAN ID, deprive the
tag or keep the tag unchanged
(whichever is done
determined by the port hybrid
vlan vlan-id-list { tagged |
untagged } command) and
send the packet.
