switchport mode
This command configures the VLAN membership mode for a port. Use the no form
to restore the default.
Syntax
switchport mode {hybrid | trunk | dot1q-tunnel}
no switchport mode
• hybrid - Specifies a hybrid VLAN interface. The port may transmit tagged
or untagged frames.
• trunk - Specifies a port as an end-point for a VLAN trunk. A trunk is a direct
link between two switches, so the port transmits tagged frames that identify
the source VLAN. Note that frames belonging to the port’s default VLAN
(i.e., associated with the PVID) are also transmitted as tagged frames.
• dot1q-tunnel - For an explanation of this command see page 30-21.
Default Setting
All ports are in hybrid mode with the PVID set to VLAN 1.
Command Mode
Interface Configuration (Ethernet, Port Channel)
