Question
What happens to switch ports after the VLAN to which they are assigned is deleted?
Solution
When a VLAN to which switch ports are assigned is deleted, the following happens:
-
The switch ports that were assigned to the deleted VLAN become inactive. They no longer pass traffic for the deleted VLAN.
-
The switch ports return to their default VLAN configuration, which is typically VLAN 1 in most switches.
-
The switch ports are still operational, but they are not part of any VLAN until they are reassigned to a new VLAN.
-
Any settings or configurations that were specific to the deleted VLAN are also deleted. This includes things like VLAN name, VLAN ID, and any VLAN-specific settings.
-
If the switch ports were part of a trunk link, they will stop passing traffic for the deleted VLAN. However, they will continue to pass traffic for any other VLANs that are still active on the trunk link.
-
If the switch ports were configured with a Voice VLAN, this configuration will also be deleted when the VLAN is deleted.
In summary, when a VLAN is deleted, the switch ports that were assigned to it become inactive and return to their default configuration until they are reassigned to a new VLAN.
