How Do I Restore the Default VLAN Configuration of an Interface?

How Do I Restore the Default VLAN Configuration of an Interface?

The default VLAN configuration of an interface depends on the default VLAN of the interface and the VLAN that the interface joins. By default, the default VLAN configuration of an interface is as follows:
  • Access: The default VLAN is VLAN 1. An access interface joins VLAN 1 in untagged mode.
  • Trunk: The default VLAN is VLAN 1. A trunk interface joins VLAN 1 in tagged mode.
  • Hybrid: The default VLAN is VLAN 1. A hybrid interface joins VLAN 1 in untagged mode.
  • Dot1q-tunnel: The default VLAN is VLAN 1. A dot1q-tunnel interface joins VLAN 1.
  • Negotiation-auto or Negotiation-desirable: If the interface is negotiated as an access interface, the default VLAN configuration of that interface is the same as that of the access interface. If the interface is negotiated as a trunk interface, the default VLAN is VLAN 1 and the interface joins VLANs 1 to 4094 in tagged mode.

Run the display this include-default | include link-type command in the interface view to check the link type of the interface, and then perform one of the following configurations to restore the default configuration of the interface.

  • Restore the default VLAN configuration of an access or dot1q-tunnel interface.
