Preserving User-Configured VLAN Definitions
When the VLAN mode is set to either of the Multiple VLAN mode, user-
configured VLAN definitions cannot be created or modified. However,
the software preserves user-configured VLANs that were configured
before multiple VLAN mode was enabled. When the user switches back
to user-configured VLANs mode, the software automatically enables the
user-configured VLANs with the pre-existing configuration.
