Regulations for Double VLANs
Some rules and regulations apply with the implementation of the Double VLAN procedure.
1. All ports must be configured for the SPVID and its corresponding TPID on the Service Provider’s edge switch.
2. All ports must be configured as Access Ports or Uplink ports. Access ports can only be Ethernet ports while Uplink ports
must be Gigabit ports.
3. Provider Edge switches must allow frames of at least 1522 bytes or more, due to the addition of the SPVID tag.
4. Access Ports must be an un-tagged port of the service provider VLANs. Uplink Ports must be a tagged port of the service
provider VLANs.
5. The switch cannot have both double and normal VLANs co-existing. Once the change of VLAN is made, all Access
Control lists are cleared and must be reconfigured.
6. Once Double VLANs are enabled, GVRP must be disabled.
7. All packets sent from the CPU to the Access ports must be untagged.
8. The following functions will not operate when the switch is in Double VLAN mode:
•
Guest VLANs
•
Web-based Access Control
•
IP Multicast Routing
•
GVRP
•
All Regular 802.1Q VLAN functions
