Configuring VLAN Membership
Cisco Small Business SG200 Series 8-port Smart Switches Administration Guide
For example, assume a General port is an untagged member of VLANs 1, 10, and
20, and the port's PVID is 1.
When the port is changed to a Trunk port, VLAN 1 becomes the native VLAN. The
Trunk port remains a member of VLANs 10 and 20, but now with tagging enabled.
Deleting a VLAN
When a VLAN is deleted, the following actions occur:
•
If the deleted VLAN was a Trunk port's native VLAN, the trunk port's native
VLAN and PVID are changed to the default VLAN.
•
If an Access port was a member of the deleted VLAN, the Access port
becomes a member of the default VLAN and its PVID is changed to the
default VLAN.
•
If a General port was configured to use the VLAN ID as its PVID, the General
port's PVID is changed to the default VLAN ID. No other VLAN memberships
are changed.
You can use these pages to view and configure VLAN memberships:
•
The Port to VLAN page enables you to select a VLAN and configure its
member ports. See
•
The Port VLAN Membership page enables you to select a port and
configure it as a member of one or more VLANs. See
VLAN
Membership.
By default, all ports are members of VLAN 1. You can change the VLAN
membership of any port. VLAN memberships can be configured as tagged or
untagged.
•
If the switch receives an untagged frame from a VLAN, the switch will insert
a VLAN tag before forwarding the frame to the egress ports that are
configured as tagged members of the VLAN.
•
If the switch receives an untagged frame from a VLAN, the switch will
forward the frame as is to egress ports that are configured as untagged
members of the VLAN.
