switchport trunk native vlan
The switchport trunk native vlan Interface Configuration mode command defines the port as a
member of the specified VLAN, and the VLAN ID as the "port default VLAN ID (PVID)". To
configure the default VLAN ID, use the no form of this command.
Syntax
switchport trunk native vlan vlan-id
no switchport trunk native vlan
vlan-id — Valid VLAN ID of the native VLAN.
•
Default Configuration
If default VLAN is enabled, then the VID=1, otherwise VID = 4095.
Command Mode
Interface Configuration (Ethernet, port-channel) mode
User Guidelines
•
This command has the following consequences: incoming untagged frames are assigned to
this VLAN and outgoing traffic in this VLAN on this port is sent untagged (despite the
normal situation where traffic sent from a trunk-mode port is all tagged).
•
The command adds the port as a member in the VLAN. If the port is already a member in the
VLAN (not as a native), it should be first removed from the VLAN.
Example
The following example g16, in trunk mode, is configured to use VLAN number 123 as the "native"
VLAN.
console(config)# interface ethernet g16
console(config-if)# switchport trunk native vlan 123
switchport general allowed vlan
The switchport general allowed vlan Interface Configuration mode command adds or removes
VLANs from a general port.
Syntax
switchport general allowed vlan add vlan-list [tagged | untagged]
switchport general allowed vlan remove vlan-list
•
add vlan-list — List of VLAN IDs to add. Separate non-consecutive VLAN IDs with a
comma and no spaces. A hyphen designates a range of IDs.
