Setting the Default VLAN

STEP 4
Setting the Default VLAN
Cisco Small Business SG200 Series 8-port Smart Switch
• PVID—When this option in selected, the port uses the selected VLAN ID as
its port VLAN ID (PVID). The port assigns the PVID to all untagged frames
received on the port before forwarding. The following configuration rules
apply:
- If the interface VLAN mode is General, any VLAN of which the interface is
a Tagged or Untagged member can be selected to provide the PVID.
- If the interface VLAN mode is Trunk, the PVID is set to the VLAN ID of
which the port is a tagged member.
- If the interface VLAN type is Access, the PVID is set to the Access VLAN
ID and this field cannot be modified.
When you select the Untagged, Tagged, and PVID options and move the VLAN to
the Selected list, a U, T, and/or P is appended to the VID.
Click Apply and then click Close. Your changes are saved to the Running
Configuration.
By default, the switch automatically creates VLAN 1 as the default VLAN for all
ports and link aggregation groups (LAGs). If a port has no VLAN memberships, the
switch automatically configures it as a member of the default VLAN.
You can use the Default VLAN Settings page to change the default VLAN.
When the VID of the default VLAN is changed:
• Ports that were members of the original default VLAN are removed as
members of that VLAN and are configured as members of the new default
VLAN.
• The Port VLAN Identifier (PVID) of the ports that were members of the
original default VLAN is changed to the VID of the new default VLAN.
• If the management VLAN was the same as the original default VLAN, then
the management VLAN is updated to the new default VLAN provided there
is at least one member port. If DHCP is enabled, the switch attempts to
renew the switch IP address through DHCP.
