VLAN Configuration
195
ports from the specified VLAN.
Parameter: ethernet is the Ethernet port to be added. portchannel means that the port
to be added is a link-aggregation port. interface-name port name, such as e1/1. If this
option is selected, ethernet or portchannel should not be. interface-list is the port list to
be added or deleted, “;” and “-” are supported, for example: ethernet1/1;3;4-7;8.
Command mode: VLAN Mode.
Default: A newly created VLAN contains no port by default.
Usage Guide: Access ports are normal ports and can join a VLAN, but a port can only
join one VLAN for a time.
Example: Assign Ethernet port 1，3，4-7，8 of VLAN100.
Switch(Config-Vlan100)#switchport interface ethernet 1/1;3;4-7;8
15.1.34 switchport mode
Command: switchport mode {trunk | access | hybrid}
Function: Set the port in access mode, trunk mode or hybrid mode.
Parameter: trunk means the port allows traffic of multiple VLAN; access indicates the
port belongs to one VLAN only; hybrid means the port allows the traffic of multi-VLANs
to pass with tag or untag mode.
Command mode: Port Mode.
Default: The port is in Access mode by default.
Usage Guide: Ports in trunk mode is called Trunk ports. Trunk ports can allow traffic of
multiple VLANs to pass through. VLAN in different switches can be interconnected with
the Trunk ports. Ports under access mode are called Access ports. An access port can
be assigned to one and only one VLAN at a time. Hybrid ports can allow traffic of multiple
VLANs to pass through, receive and send the packets of multiple VLANs, used to
connect switch, or user’s computer. When Hybrid ports and Trunk ports receive the data,
the deal way is same, but the deal way is different in sending the data. Because Hybrid
ports can allow the packets of multiple VLANs to send with no tag, however, Trunk ports
can only allow the packets of the default VLAN to send with no tag. The attribute of ports
can not directly convert between Hybrid and Trunk, it must configure to be access at first,
then configure to be Hybrid or Trunk. When the Trunk or Hybrid attribute is cancelled, the
port attribute restores the default (access) attribute and belongs to vlan1.
Example: Set port 5 to trunk mode and port 8 to access mode, port 10 to hybrid mode.
