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.
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 this switch can
intercommunicate with the same VLAN on the peer switch.
