[Initial value]
none
[Input mode]
interface mode
[Description]
Sets the VLAN ID that is associated as a trunk port with the applicable interface.
If this is executed with the "no" syntax, all associated VLAN IDs are deleted and the port type is changed to access port.
[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)
