Static Virtual LANs (VLANs) VLAN Operating Rules Parameter No - or Auto Forbid Effect on Port Participation in Designated VLAN No: Appears when the switch is not GVRP-enabled; prevents the port from joining that VLAN. Auto: Appears when GVRP is enabled on the switch; allows the port to dynamically join any advertised VLAN that has the same VID Prevents the port from joining the VLAN, even if GVRP is enabled on the switch. VLAN Operating Rules ■ DHCP/Bootp: If you are using DHCP/Bootp to acquire the switch's configuration, packet time-to-live, and TimeP information, you must designate the VLAN on which DHCP is configured for this purpose as the Primary VLAN. (In the factory-default configuration, the DEFAULT_VLAN is the Primary VLAN.) ■ Per-VLAN Features: IGMP and some other features operate on a "per VLAN" basis. This means you must configure such features separately for each VLAN in which you want them to operate. ■ Default VLAN: You can rename the default VLAN, but you cannot change its VID (1) or delete it from the switch. ■ VLAN Port Assignments: Any ports not specifically removed from the default VLAN remain in the DEFAULT_VLAN, regardless of other port assignments. Also, a port must always be a tagged or untagged member of at least one port-based VLAN. ■ Voice-Over-IP (VoIP): VoIP operates only over static, port-based VLANs. ■ Multiple VLAN Types Configured on the Same Port: A port can simultaneously belong to both port-based and protocol-based VLANs. ■ Protocol Capacity: A protocol-based VLAN can include up to four protocol types. In protocol VLANs using the IPv4 protocol, ARP must be one of these protocol types (to support normal IP network operation). Otherwise, IP traffic on the VLAN is disabled.
