By default, trunk ports are members of all existing VLANs and will automatically participate in any newly created VLANs. The administrator can restrict the VLAN membership of a trunk port. VLAN membership for tagged frames received on a trunk port is configured separately from the membership of the native VLAN. To configure a trunk port to accept frames only for a single VLAN, both the native VLAN and the tagged VLAN membership settings must be configured. Access ports accept untagged traffic and traffic tagged with the access port PVID. Untagged ingress traffic is considered to belong to the VLAN identified by the PVID. GVRP The GARP VLAN Registration Protocol (GVRP) helps to dynamically manage VLAN memberships on trunk ports. When GARP is enabled, switches can dynamically register (and de-register) VLAN membership information with other switches attached to the same segment. Information about the active VLANs is propagated across all networking switches in the bridged LAN that support GVRP. You can configure ports to forbid dynamic VLAN assignment through GVRP. The operation of GVRP relies upon the services provided by the Generic Attribute Registration Protocol (GARP). GVRP can create up to 1024 VLANs. For information about GARP timers, see "What Are GARP and GMRP?" on page 702. Double-VLAN Tagging For trunk ports, which are ports that connect one switch to another switch, the PowerConnect 8000/8100-series switches support double-VLAN tagging. This feature allows service providers to create Virtual Metropolitan Area Networks (VMANs). With double-VLAN tagging, service providers can pass VLAN traffic from one customer domain to another through a metro core in a simple and cost-effective manner. By using an additional tag on the traffic, the switch can differentiate between customers in the MAN while preserving an individual customer's VLAN identification when the traffic enters the customer's 802.1Q domain. 556 Configuring VLANs
