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.
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.
An access port can only be added to one VLAN, while hybrid and trunk ports can
be added to multiple VLANs.
n
The access ports or hybrid ports must be added to an existing VLAN.

If the VLAN ID is not the

Deprive the tag from the packet
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, 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).
