[Note]
This command can be set only for a LAN/SFP port or logical interface for which the
switchport mode trunk
command is set.
If this command is applied to a logical interface, the settings of every LAN/SFP port associated with that interface are changed.
If the port type is changed to access port, the setting of this command returns to the default setting.
If this is set with "all" or "except" specified, the content of a subsequently changed
vlan
command is always applied.
If this is set with "all" or "except" specified, making the following settings will change the remaining affiliated VLAN IDs to
the settings that were specified by "add."
• If you specify "remove" to delete a VLAN ID that is associated
• If you use the
switchport trunk native vlan
command to specify an associated VLAN ID
If you make this setting with "except" specified, and then associate the VLAN ID that had been excluded by specifying "add",
the associated VLAN ID is changed to the setting specified by "add".
If you specify "remove" and then specify an unassociated VLAN ID, an error occurs.
For the setting of this command and the
switchport trunk native vlan
command, the last-specified command takes priority.
• If you use the
switchport trunk native vlan
command to specify a VLAN ID that was associated by this command, it is
removed from the specified VLAN ID.
• If you specify and associate a VLAN ID that was set by the
switchport trunk native vlan
command,
switchport trunk
native vlan none
is set.
If you specify the
switchport trunk allowed vlan add
command with a combination of "-" or "," in the
vlan-ids
, the command
setting will fail if you revert to an older version (Rev.2.00.08 or earlier). As a result, normal communication might become
impossible. (Example setting: switchport trunk allowed vlan add 101,103-105)
[Example]
Set LAN port #1 as the trunk port, and associate it to VLAN #2.
SWR2311P(config)#interface port1.1
SWR2311P(config-if)#switchport mode trunk
SWR2311P(config-if)#switchport trunk allowed vlan add 2

VLAN ID set by the
vlan
command
[Initial value]
switchport trunk native vlan 1
[Input mode]
interface mode
[Description]
Sets the native VLAN for the applicable interface.
If "none" is specified, the native VLAN is disabled. This means that untagged frames received by the applicable interface are
discarded.
If this command is executed with the "no" syntax, the setting returns to the default.
[Note]
This command can be set only for a LAN/SFP port or logical interface for which the
switchport mode trunk
command is set.
If this command is applied to a logical interface, the settings of every LAN/SFP port associated with that interface are changed.
If the port type is changed to access port, the setting of this command returns to the default setting.
For the setting of this command and the setting of the
switchport trunk allowed vlan
command, the last-specified command
takes priority.
