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 1/5 to trunk mode and port 1/8 to access mode, port 10 to hybrid
mode.
Switch(config)#interface ethernet 1/5
Switch(Config-If-Ethernet1/5)#switchport mode trunk
Switch(Config-If-Ethernet1/5)#exit
Switch(config)#interface ethernet 1/8
Switch(Config-If-Ethernet1/8)#switchport mode access
Switch(Config-If-Ethernet1/8)#exit
Switch(config)#interface ethernet 1/10
Switch(Config-If-Ethernet1/10)#switchport mode hybrid
Switch(Config-If-Ethernet1/10)#exit
9.1.3.11 switchport trunk allowed vlan
Command: switchport trunk allowed vlan {WORD | all | add WORD | except
WORD|remove WORD}
no switchport trunk allowed vlan
Function: Set trunk port to allow VLAN traffic; the "no switchport trunk allowed vlan"
command restores the default setting.
Parameter: WORD is the list of VLANs allowed to pass through in the specified Trunk
port; keyword "all" indicate allow all VLAN traffic on the Trunk port; "add" add assigned
VIDs behind allow vlan; "except" all VID add to allow vlan except assigned VIDs;
