802.1Q Vlan - D-Link DES-3528 User Manual

xStack DES-3528 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual
Customer VLANs using SPVLANs, thus greatly regulating traffic and routing on the Service Provider switch. This
information is then routed to the Service Provider's main network and regarded there as one VLAN, with one set of
protocols and one routing behavior.
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
•
