packet
Access
z If the VLAN ID is just the
default VLAN ID, receive the
packet.
z If the VLAN ID is not the
default VLAN ID, discard the
packet.
Deprive the tag from the packet
and send the packet.
Trunk
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.
Hybrid
Receive the
packet and add
the default tag to
the packet.
z If the VLAN ID is just the
default VLAN ID, receive the
packet.
z 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.
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.
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, deprive the
tag or keep the tag unchanged
(whichever is done is
determined by the port hybrid
vlan vlan-id-list { tagged |
untagged } command) and
send the packet.
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.
