Configuring Default VLAN Settings
When using factory default settings, the switch automatically creates VLAN 1 as the default VLAN, the default interface status of all ports is Trunk, and all ports are configured as untagged members of the default VLAN.
The default VLAN has the following characteristics:
- It is distinct, non-static/non-dynamic, and all ports are untagged members by default.
- It cannot be deleted.
- It cannot be given a label.
- It cannot be used for any special role, such as unauthenticated VLAN or Voice VLAN.
- If a port is no longer a member of any VLAN, the switch automatically configures the port as an untagged member of the default VLAN. A port is no longer a member of a VLAN if the VLAN is deleted or the port is removed from the VLAN.
- RADIUS servers cannot assign the default VLAN to 802.1x supplicants by using Dynamic VLAN Assignment.
When the VID of the default VLAN is changed, the switch performs the following on all the ports in the VLAN, after saving the configuration and rebooting the switch:
- Removes VLAN membership of the ports from the original default VLAN (possible only after reboot).
- Changes the PVID (Port VLAN Identifier) of the ports to the VID of the new default VLAN.
- The original default VLAN ID is removed from the switch. To be used, it must be recreated.
- Adds the ports as untagged VLAN members of the new default VLAN.
To change the default VLAN:
- Click VLAN Management > Default VLAN Settings. The Default VLAN Settings page opens.
- Enter the value for the following field:
- Click Apply.
- Click Save (in the upper-right corner of the window) and save the Running Configuration to the Startup Configuration.
The Default VLAN ID After Reset becomes the Current Default VLAN ID after you reboot the switch.
