Default VLAN
All interface ports are administratively up (in L2 mode) and are automatically placed in the default VLAN as untagged interfaces.
When you assign a port to a non-default VLAN in Trunk mode, the interface remains an untagged member of the default VLAN and a
tagged member of the new VLAN. When you assign a port to a non-default VLAN in Access mode, it removes from the default VLAN and
is assigned to the new VLAN as an untagged member of the new VLAN.
• VLAN 1 is the default VLAN.
• You cannot delete the default VLAN. However, you can change the default VLAN ID number using the default vlan-id command.
• You cannot assign an IP address to the default VLAN.
Use the show vlan command to verify that the interface is part of the default VLAN (VLAN 1).

Create or remove VLANs
You can create VLANs and add physical interfaces or port-channel (LAG) interfaces to the VLAN as tagged or untagged members. You can
add an Ethernet interface as a trunk port or as an access port, but it cannot be added as both at the same time.

The shutdown command stops L3 (routed) trac only. L2 trac continues to pass through the VLAN. If the VLAN is not a routed VLAN
congured with an IP address, the shutdown command has no eect on VLAN trac.
