Moving ports between C-VLANs and S-VLANs (mixed VLAN mode)
An interface has to beGVRP-disabled to move it from the C-VLAN to the S-VLAN space. This is because S-VLANs of mixed VLAN mode do not support provider-GVRP, and also because a GVRP-enabled configuration (when the port is a C-VLAN member) is in the context of customer-GVRP which must be disabled before the port can operate in the S-VLAN space.
Interface should not have any mirroring or monitoring sessions when moving between C-VLANs and S-VLANs. The configuration on all mirror/monitor sessions that involve the port must be removed.
An interface that has auth-vid or unauth-vid configuration cannot move into the S-VLAN space. They have to be unset.
Interfaces cannot have LACP enabled (active or passive modes) when moving into the S-VLAN space. They have be disabled.
