Important Considerations

■The default VLAN always uses VLAN ID (VID) 1 and the name Default. For Layer 3 systems and modules, it also uses the protocol type

unspecified.

■The VLAN ID (VID) is used as the 802.1Q tag if tagging is enabled for a port.

■The VLAN statistics for the CoreBuilder 3500 and CoreBuilder 9000 Layer 3 switching modules are valid only under one of the following conditions:

■If the VLANs are defined for the same protocol type (or for the type called unspecified) and do not share any ports. Example: IP VLAN1 has ports 1 through 6 and IP VLAN2 has ports

7 through 12.

■If the VLANs are explicitly defined for different protocol types. In this case, the VLANs may share ports. Example: An IP VLAN and an IPX VLAN both use ports 2 through 4.

■As of Release 3.0.0, the CoreBuilder 3500 system and

CoreBuilder 9000 Layer 3 modules support one of three origins for a VLAN:

■If you explicitly create the VLAN with a bridge vlan define operation, the origin of the VLAN is static.

■If you create a router port IP interface (for which the system automatically creates a router port VLAN), the origin of the router port VLAN is router.

■If you enable dynamic port-based VLAN configuration via the GARP VLAN Registration Protocol (GVRP), the origin is GVRP.
